Form K: the certificate that takes your Korean duty down to the FTA rateWhat it proves, who in China signs it, and why it needs to be in your broker's file before the vessel loads
Korea has been cutting duty on Chinese-origin goods since December 2015 and keeps cutting until the phase-out ends. The lower rate is not automatic at the border: your import declaration only lands in the FTA column when it claims the agreement rate and carries origin evidence behind it. Form K is that evidence.
Qingdao, one of the busiest gateways for China–Korea cargo. The certificate has to be right before the box gets on the ship.
The short version
Form K is the preferential certificate of origin issued under the China–Korea Free Trade Agreement. Its official name is the Certificate of Origin for the China–Korea FTA; in the trade people call it Form K, the K certificate, or the CK certificate. The certificate number carries the treaty identifier K, and the form is completed in English.
It is issued in China by China Customs at the port of export or by CCPIT and its local branches, filed online and self-printed on A4 in color with the electronic seal and signature. File before or at the time of shipment, or within seven working days after it. Miss that window and a certificate can still be issued retroactively, up to one year from the shipment date, marked ISSUED RETROACTIVELY. Either way it stays valid for twelve months from the date of issue.
What it buys you: by the end of the phase-out Korea removes duty on 92% of its tariff lines for Chinese-origin goods, in cuts spread across 10, 15 and 20 years. Which line your product sits on decides the rate; the certificate decides whether you get that rate at all. Without it, your broker files at the MFN rate and the difference is collected at the border.

Definition and legal basis
What Form K actually is
The two governments signed the agreement in June 2015 and put it into force on December 20, 2015 with the first round of tariff cuts; a second round followed on January 1, 2016. Form K operates under the origin rules in Chapter 3 of that agreement and the form set out in Annex 3-C.
The document is one page of numbered boxes: exporter, producer, consignee, means of transport and route, remarks, item lines with marks, description, six-digit HS code, origin criterion, quantity and invoice number and date, then the exporter's declaration and the issuing body's certification. It carries the word ORIGINAL and a unique certificate number, and box 10 states the basis on which the goods qualify — WO for wholly obtained, WP for produced entirely from originating materials, PSR where a product-specific rule is met. A certificate that leaves box 10 vague, or ticks a rule the shipment does not meet, is a certificate waiting to be pulled.
On the Chinese side two instruments govern it: the Measures on the Administration of the Origin of Import and Export Goods under the China–Korea FTA (GACC Order No. 229, as amended by Order No. 273 in 2024), which is the rulebook on how origin is decided, and the Measures for the Administration of Certificate of Origin Visa for Export Goods (GACC Order No. 270, effective September 1, 2024), which covers filing, review, issuance and reissuance.
Origin is decided one of three ways. Wholly obtained: grown, mined, caught or produced entirely in China or Korea. Produced exclusively from originating materials: everything that went into the goods already qualifies. Product-specific rule in Annex 3-A: non-originating materials were used, but the finished goods meet the rule written for their six-digit subheading — a change in tariff classification (CC, CTH or CTSH), a regional value content threshold (RVC 40 is the common one), a process requirement, or a combination of them. That third route is how nearly all manufactured exports qualify.
Where value content is the test, the calculation is (FOB value − value of non-originating materials) ÷ FOB value × 100%. Four supporting rules matter as much as the main one. Bilateral cumulation: Chinese materials count as Korean and Korean materials count as Chinese, so content from either side builds the regional value. De minimis: non-originating materials up to 10% of the FOB value are disregarded, but only where the rule is a tariff change. Sets: goods put up in a set may carry non-originating content up to 15% of the FOB value. Direct transport: goods may pass through a third country but may stay there no more than 12 months, must remain under customs control, and may not be manipulated beyond unloading, storage, repacking for preservation and similar handling.
A certificate is a claim, not a finding. The issuing office reviews the paperwork; it does not audit your bill of materials. If the origin criterion does not survive a Korean verification, the duty you did not pay comes back as an assessment, plus penalties in serious cases — and the exposure sits with the importer of record, which is you.
What the certificate states, in plain terms
Who shipped it — exporter name and address, matching the export declaration.
Who made it — producer, or “SAME” where the exporter is the producer.
Who receives it — consignee, usually you or your Korean entity.
How it moved — departure date, vessel or flight, port of loading, port of discharge.
What it is — description, six-digit HS code, quantity, gross weight, invoice number and date.
Why it qualifies — box 10, the origin criterion, stated as a rule rather than an opinion.
One certificate covers one shipment and up to 20 item lines. Split consignments need separate certificates, and a certificate cannot be recycled for a later shipment of similar goods.
Why it matters to you
You are the importer of record. Here is what this certificate does for you.
Your company name goes on the import declaration, so the duty assessment, the verification and the penalty exposure all land on your side of the transaction. Form K is the document that moves your goods into the FTA column and keeps them there.
It moves your declaration into the FTA column
Korea Customs applies the agreement rate only when the declaration claims it and the origin evidence is there. No certificate, no claim — and the entry is assessed at MFN.
The gap is not small on every line
Korea's MFN rates on many industrial inputs are already low, so the certificate changes little. On textiles, apparel, footwear, bags, home goods and a range of consumer products the difference is real money, and that is where the certificate earns its keep.
It is the document your broker files against
Your Korean broker needs the certificate number to link the preference claim to the import declaration. Paperwork that arrives late means an entry at the wrong rate, then a correction, a refund claim, or both.
It is the answer to a verification letter
Korea Customs verifies origin after release. The certificate, the invoice, the bill of materials and the production record are what closes the query. A thin file loses the preference; a clean file ends the conversation.
It feeds refunds, quotas and trade remedies
If the certificate arrives after the entry was filed at MFN, the agreement allows a refund application up to one year after importation. Anti-dumping cases, quota administration and import statistics all run on origin too.
It gives your buyers a landed cost to plan on
Landed cost is duty plus VAT plus freight plus clearance. Take duty out of the model and the price you can afford to pay your supplier rises by that amount — which is the real argument for the certificate, decided before the order ships.
Duty is not the whole bill. Korea charges 10% VAT on imports at the border whatever the tariff treatment, and the VAT base includes duty. Form K removes duty, which also trims the VAT base. It does not touch VAT itself, the customs processing charge, or inspection costs on food, plants and wood packaging.
Issuing offices
Where to get it: two official channels
Only two kinds of office in China can issue a Form K — China Customs, and CCPIT with its local branches. Both produce a certificate Korea accepts, and both are filed online. Which one you use is usually settled by your contract, your letter of credit, or where your supplier already files.
Channel
What it is
Where it is filed
Use it when
China Customs
Government issuing authority — the customs house covering the port of export
Internet + Customs at online.customs.gov.cn (origin certificate module), or the Single Window at singlewindow.cn
You want the certificate tied to the export declaration and to electronic origin data
CCPIT
Chamber issuer — the China Council for the Promotion of International Trade and its local branches
CCPIT origin certificate system at co.ccpit.org, or declare.ecoccpit.net
Your buyer or bank wants a chamber-issued certificate, or the supplier already files everything through CCPIT
Filed online, printed in the supplier's own office
Filing is electronic end to end. Submit in one of the systems above, the authority reviews it online, and once it clears the certificate is self-printed — A4, color, with the electronic seal and the authorized signature. That printout carries the same legal effect as a pre-printed form, and the agreement expects only one original hard copy to be printed.
There is no residency requirement. Any customs house or local CCPIT branch takes an online filing. Cargo out of Shenzhen and the Pearl River Delta is normally filed with Shenzhen Customs or CCPIT Shenzhen, which keeps review and rework in one place. Cargo out of Qingdao, Weihai, Shanghai, Ningbo, Tianjin, Dalian or Xiamen is filed with the office that matches the port of export — and those northern ports are where most Korea-bound volume actually loads.
The electronic record is not the paper. Korea Customs can confirm a certificate through the verification channel, but your broker still needs the certificate number at the time the declaration is filed, and your bank may still want the signed original. Send the PDF the day it clears and courier the original with the rest of the set.
Shipping from a port the exporter is not registered at: the exporter name and address, the routing, the port of loading and the departure date on the certificate have to describe the actual movement. A Shenzhen-based exporter loading in Qingdao still shows Qingdao. When the certificate says one routing and the bill of lading says another, that mismatch is the first thing a verification asks about.
Who applies
Who can file: three routes, and one line we do not cross
The rule is short. The certificate is issued on application by the exporter, the producer, or an authorized representative acting under the exporter's responsibility. In practice that produces three arrangements.
The factory files
The manufacturer registers, keeps its own profile current and files its own certificates. Tightest control over origin data, and it works well when the product range is narrow and the documents desk is staffed.
The trading company files
The exporter applies in its own name, so the certificate matches the invoice and the bill of lading it issued. The usual setup for high-volume exporters with a dedicated documents team.
We file as your agent
The certificate still carries your supplier's name or yours — never ours. This is the route for importers whose supplier has no registration, no documents desk, or cargo spread across several ports.
First filing: what has to be set up
Before a first certificate can be filed, the exporter's profile has to exist in the system: business licence, unified social credit code, Chinese and English name and address, and the customs registration number. Self-printing also needs the company seal and the signatory's signature uploaded and authorized. Where we file as agent, the power of attorney is registered in the e-port system as well as signed on paper.
None of this is difficult; all of it takes a day or two when the supplier has never filed before. That is the part to start on the day the order is confirmed, not the day the container is booked.
Our line: we file certificates; we do not sell them. The exporter on the certificate, the seller on the invoice and the shipper on the bill of lading have to point at one real transaction. We turn down borrowed company names, invented goods descriptions, and values that do not match the payment. A false origin declaration is the declarant's legal exposure, and the duty consequence lands on you at the other end.
Most rejections are caught here, at the desk, before the filing goes in — not at the Korean border.
Third-party invoices are allowed. Where the invoice is issued by a company outside China or Korea — a Hong Kong trading entity, for instance — the agreement does not let Korea reject the certificate for that reason alone. The non-party operator is named in box 5, and the invoice number and date still have to line up with what your broker files.
Timing
When to file: before the vessel loads, with a year of runway behind it
The agreement sets the window precisely: issued before shipment, at the time of shipment, or within seven working days after it. That is not bureaucratic fussiness. The certificate has to carry the departure date, the vessel and voyage, the port of loading and the port of discharge, and none of those exist until the booking is confirmed.
Booking confirmed
Lock the movement
Departure date, vessel and voyage, discharge port are fixed. Pull the invoice, packing list, HS code and the origin support for the goods.
Before cutoff
Settle the origin call
Decide which Annex 3-A rule the product meets and assemble the bill of materials or cost build-up that proves it. Do it before filing, not after a query.
Filed online
Reviewed and issued
The issuing office completes review within two business days of accepting the filing. Self-print, then check the number, the seal, the signature and the ORIGINAL marking.
Same day
Into your broker's hands
PDF goes out ahead so your Korean broker can prepare the declaration; the original travels with the documents or by courier.
If the vessel has already sailed
You are still inside the rules. A certificate can be issued retroactively up to one year from the shipment date, filed with the bill of lading or air waybill as proof of that date, and it carries the words ISSUED RETROACTIVELY in the remarks box. Good cause is required — force majeure, an involuntary error, an omission — and the issuing office will want to know what it was. Two practical limits: no retroactive certificate where the goods have been returned or where origin cannot be established, and some letters of credit refuse a certificate dated after the bill of lading.
Three dates, three jobs. The shipment date on the bill of lading decides whether the certificate counts as retroactive and starts the one-year retroactive window. The issue date starts the twelve-month validity clock. The import declaration date in Korea is when the preference is actually claimed — the certificate has to be in force on that date, which is why a certificate issued early in a long transit still needs watching.
A mistake is not a new application. If a box is wrong, surrender the original and have it amended or reissued; the replacement carries the original validity and does not buy another year. If the certificate is lost, stolen or destroyed before use, ask for a certified true copy inside the validity period, marked as a true copy of the original and quoting its number and date. Korean customs will also give you 5 to 30 working days to produce a corrected certificate where the defect is minor — legibility, a face defect, a mismatch against the declaration.
Process
From origin call to certificate in hand
Filing it yourself and having us file it walk the same official path. What changes is who fills the boxes, who checks them against the rest of the file, and who does the rework when something is wrong.
Confirm the agreement applies
Destination Korea, goods of Chinese origin, and a tariff line where duty is still charged. If the line is at zero MFN anyway, the certificate is paperwork for the file, not a saving.
Settle the origin criterion
Read the Annex 3-A rule for the six-digit subheading, then work out whether the goods are wholly obtained, made from originating materials only, or meet a tariff-change, value-content or process rule.
Build the origin file
Bill of materials, supplier invoices for the non-originating inputs, cost build-up where value content is the test. This is the file that answers a verification six months later.
Reconcile the documents
Invoice, packing list, bill of lading. Number and date, value, package count, gross and net weight, marks — the four corners have to agree before anything is filed.
File in the system
Exporter, producer and consignee details, transport and routing, goods description taken line by line from the invoice, HS code, origin criterion. No catch-all wording in the description box.
Clear review
Customs or CCPIT reviews within two business days and normally lists every needed correction in one pass, which is why a clean file saves a full round trip.
Print and verify
Self-print A4 in color, or collect at the counter. Check the certificate number, seal, signature and the ORIGINAL marking before the page leaves the office.
Deliver and archive
PDF to your broker immediately, original with the document set or by courier. Keep the certificate and the application file for three years — that is what gets produced when a verification arrives.
The field that gets certificates bounced is box 10. Filing WO on goods made from imported components, or claiming a tariff change that never happened, is a false declaration — not a formatting slip. The issuing office can ask for the bill of materials, Korea can verify the same claim, and the correction path runs through amendment or reissuance while the container is already at sea.
Documents
What we need from you
The list is short, and one item on it runs longer than a plain CO requires: Form K asks for the basis of the origin claim, and that is the part reviewers and Korean customs both read closely.
Always required
Commercial invoice — English, with number and date, Incoterms, unit prices, total value and consignee details.
Packing list — package count and type, gross and net weight, marks and numbers (N/M where there are none).
HS code — six digits at minimum, consistent with the invoice and the export declaration, and mapped to the Korean HSK line.
Origin support — material sources and the manufacturing step performed in China; bill of materials and cost breakdown where the rule needs them.
Exporter details — business licence, unified social credit code, Chinese and English name and address, customs registration number.
Depending on the shipment
Bill of lading or air waybill — required for a retroactive certificate, as proof of the shipment date.
Power of attorney — when we file as your agent; the entrustment is registered in the e-port system too.
Non-party invoice instruction — if the seller on the invoice is not the Chinese exporter, say so up front; the operator is named in box 5.
Transshipment evidence — through bill of lading, discharge and reload records, or a non-manipulation certificate where the routing passes a third country.
Send the file, not a summary. A screenshot of an invoice, a description typed into an email, or a value quoted from memory all cost a round trip. The reviewer compares fields against the actual documents.
Origin claims are checked against real cargo. The paperwork has to describe what is actually in the box.
Small consignments
Under USD 700 — Korea waives the certificate requirement for a consignment of originating goods with a customs value up to USD 700.
Split on purpose — the waiver does not apply where the shipments were obviously arranged to avoid presenting a certificate.
Bulk is not exempt — a low value per unit does not lower the consignment value; what counts is the declared value of the whole consignment.
Cost
What it costs: nothing to the government, a per-certificate fee to us
Two separate charges, two separate reasons. The issuing office takes no certificate fee — neither China Customs nor CCPIT publishes one. What you pay is the agent's service fee for the work behind the document.
Government fee: none
China Customs issues origin certificates without a certificate charge, and CCPIT's fee schedule shows the same. Review, form stock, electronic seal and electronic signature are not billed to the applicant.
Service fee: per certificate
Our fee covers the filing work — settling the origin criterion, assembling the support file, reconciling the documents, filing, tracking review, printing, delivery, and rework if a box is wrong. Quoted per certificate.
What moves the price of a certificate
Origin work — a bill of materials and a value-content calculation take more time than a simple goods description, and some lines need both.
Rush handling — same-day issuance depends on the day's queue and needs a dedicated reviewer.
Amendments and reissuance — a wrong box, a changed invoice, or a lost original all run through review again.
Non-party invoicing — trading structures and offshore invoicing need the box 5 remark handled correctly and the invoice reconciled.
Chamber stamps and legalization — where a buyer wants chamber certification or embassy legalization, that is a separate process with its own fee.
Extras and courier — additional copies and international courier are billed at cost.
On quoting: we do not publish one headline number, because the work behind a certificate varies with the product, the HS line, and whether the origin claim has to be built from a bill of materials. Send the invoice, the packing list and the Korean HSK code, and you get an itemized quote against the actual certificate count — no teaser price followed by add-ons.
Nobody can guarantee an approval. The issuing office decides; we file, prepare and follow up. Treat any offer to “guarantee issuance” or to supply a certificate in someone else's name as a red flag. A certificate bought rather than earned is a false declaration, and the importer who files it carries the consequence.
Comparison
Form K, a plain CO, Form B and an RCEP certificate
Four documents that look alike on the page and do different jobs at a Korean import declaration. Filing the wrong one is the most common reason a preference claim fails on arrival.
Document
Code
What it does at a Korean entry
Use it when
Form K — China–Korea FTA certificate of origin
K
Supports the FTA claim: Korea's agreement rate on Chinese-origin goods, provided the Annex 3-A rule for the line is met.
Goods are Chinese origin and duty would otherwise be charged. The default choice for China-to-Korea cargo.
CO — non-preferential certificate of origin
C
Proves Chinese origin only. No treaty rate, no reduction; supports the MFN column and origin-based controls.
Your bank or broker wants proof of origin without a preference claim, or the destination has no agreement with China.
Form B — Asia-Pacific Trade Agreement certificate
B
A narrower margin than the FTA: APTA cuts apply to a negotiated list, so the rate is usually better than MFN and usually worse than Form K.
The goods fail the China–Korea origin rule but sit on the APTA concession list for Korea.
Another route to a reduced rate, on RCEP rules rather than the bilateral ones, with its own schedule for Korea.
The product fails the bilateral rule but meets the RCEP rule, or the supply chain spans several RCEP countries.
One rule of thumb. If duty at MFN is already zero, no certificate changes your bill — file for the record only. If duty is charged, match the certificate to the agreement whose origin rule your goods actually meet, not to whichever certificate is easiest to get. The same Korean buyer can legitimately have three options on one shipment, and the file has to carry the one that matches the claim.
Risk
Why some Form K certificates get pulled for verification
Issuance is the start, not the end. Korea Customs verifies preference claims after release, and the question in a verification is rarely “is there a certificate” — it is “does this certificate hold up”.
The origin claim does not hold
Imported components declared as wholly obtained, or a value-content claim that never reached the threshold. The heaviest category, and the one that survives an audit years later.
The description is too broad
“Machine parts”, “fittings”, “goods” — that is not a description. Each invoice line needs the item, the specification, the model and the quantity, with the HS code beside it.
The HS codes do not line up
The Chinese export code and the Korean HSK line can differ in structure, and the Annex 3-A rule applies to the subheading. A code mapped to the wrong line can put the goods outside the rule.
The documents disagree
Invoice date, value, package count, gross weight, marks — any difference against the packing list, bill of lading or declaration invites a closer look, and amendments cost more than clean filings.
Transshipment with no evidence
Cargo routed through Hong Kong, Busan or another hub needs proof that it stayed under 12 months, under customs control, and unmanipulated. Without a through bill of lading or a non-manipulation record, the direct-transport condition is unproven.
Expired, or retroactive and unexplained
A certificate past its twelve-month validity, or one issued after shipment without the retroactive marking and the reason behind it, does not support the claim. The entry then sits at MFN until it is corrected.
Five things to check before you send it to your broker
Certificate number — present, unique, and the same number your broker types into the declaration.
Issue date — inside the seven-working-day window, or carrying ISSUED RETROACTIVELY and a shipment date within the last year.
Goods, HS code, value, packages, weights — identical to the invoice and packing list, line by line.
Consignee and ports — your name and address, the port of loading and the port of discharge, matching the bill of lading.
Seal, signature, ORIGINAL — present and legible; a photocopy or a black-and-white print is not an original.
The clock on a verification. Korea Customs can run a verification before or after release, and may hold the preference while it runs. The exporting authority has six months from the request to return results, and the whole visit process is capped at another six months. That deadline is why the origin file is built at filing time and kept for three years, instead of being reconstructed when the letter arrives.
Questions
Frequently asked questions
The questions importers actually send us, answered without the treaty language.
What does Form K actually do at a Korean import declaration?
It is the origin evidence behind the preference claim. Your broker states in the declaration that the goods qualify under the China-Korea FTA and attaches the certificate number; Korea Customs then applies the agreement rate instead of MFN. Without a valid certificate the declaration is assessed at MFN, and the rate difference is collected at the border.
Do I need Form K, or is the invoice enough?
The invoice is not origin evidence. Korea requires a valid certificate of origin at the time the import declaration is made, issued by an authorized body in China and carrying that body's signature and seal. An exporter's own statement on the invoice is not a substitute under this agreement, and it will not move the entry into the FTA column.
Does Form K mean zero duty?
Not automatically. Korea's schedule removes duty on 92% of tariff lines for Chinese-origin goods by the end of a phase-out that runs up to 20 years, and a minority of lines stay outside the cuts. Your HSK line decides the rate; the certificate decides whether you get it. Plenty of industrial inputs are at zero MFN already, where the certificate saves nothing.
How long does issuance take?
The issuing office completes review within two business days of accepting the filing. With clean documents most certificates clear in one working day. A same-day request depends on that day's queue and has to be arranged before the filing goes in, not after.
Who can apply for Form K?
The exporter named on the certificate, or the producer of the goods, or an authorized representative acting under the exporter's responsibility. When we file on your behalf, the certificate stays in your supplier's name or yours, never in ours, and the power of attorney is registered with the issuing office.
What does a Form K cost?
The issuing authority charges no certificate fee; China Customs and CCPIT both publish a zero charge. What you pay is the agent's service fee, quoted per certificate and itemized by the work involved: origin analysis, filing, rush handling, amendment, chamber stamp or courier.
The cargo already sailed. Can we still get a certificate?
Yes, retroactively, up to one year from the shipment date, with the bill of lading or air waybill as proof of that date. The certificate carries the words ISSUED RETROACTIVELY and good cause has to be shown. Two caveats: no retroactive certificate where the goods were returned or origin cannot be established, and some letters of credit refuse a certificate dated after the bill of lading.
How long is Form K valid?
Twelve months from the date of issue, and it has to be in force on the date the import declaration is filed in Korea. Amendments and reissues carry the validity of the original rather than restarting the clock, so a correction late in the cycle does not buy another year.
What origin rule applies to my product?
Whichever rule Annex 3-A sets for your six-digit subheading: a change in tariff classification (CC, CTH or CTSH), a regional value content threshold (RVC 40 is the common one), a specific process, or a combination. Value content is (FOB value minus non-originating material value) divided by FOB value. Non-originating materials up to 10% of the FOB value may be disregarded, but only where the rule is a tariff change.
Can Chinese and Korean materials be combined?
Yes. Bilateral cumulation treats materials originating in either country as originating in the other, so Chinese content in a Korean-made input, or the reverse, counts toward the rule. Keep the supplier declarations that prove the originating status of those inputs; cumulation is only as good as the paper behind it.
What if the goods transship through Hong Kong or Busan?
Direct transport allows a third-country stop as long as the goods stay no more than 12 months, remain under customs control, and are not manipulated beyond unloading, storage, repacking for preservation or similar handling. Keep the through bill of lading, the discharge and reload records, and any non-manipulation certificate. Without them the condition is unproven at verification.
Form K or Form B or RCEP - which one do I file?
File the agreement whose origin rule your goods actually meet, and compare the resulting rate. Form K gives Korea's FTA rate on Chinese-origin goods. Form B gives the narrower APTA concession, usually better than MFN but worse than the FTA. RCEP has its own schedule and its own accumulation rules, which can help where the supply chain runs through other member countries. One shipment can qualify for all three on paper; only one claim gets filed.
