How far in advance should export clearance at Shenzhen Airport start?
For general cargo, two to three working days before departure is enough to classify, review and file with room to correct. Battery products, chemicals and cold chain need four to five, because a UN38.3 summary, hazard determination or temperature plan often has to be reissued. Same-day shipments are possible, but only when the documents are right the first time.
Does a customs release mean the cargo makes the flight?
No. Release ends the customs step. Terminal acceptance, screening, build-up and airline load planning still follow, and in peak season those queues run for hours. Plan the schedule as release time plus terminal time, never as release time alone.
What is the difference between Shenchang and the airport international terminal?
Shenchang sits in the south cargo area on Linghang Second Road and is the first international terminal in China with round-the-clock customs clearance under a smart, remote supervision model. Export cargo is filed in advance and released at the gate, where flagged shipments are separated from cleared ones automatically. The airport international terminal on Airport Fourth Road is the main facility for freighter and belly-hold cargo, where acceptance, weighing and build-up queue by flight. Shenchang suits e-commerce and urgent shipments; the main terminal suits full pallets and large consignments.
Can I export through Shenzhen without an import-export licence?
Yes, through a licensed entity acting as exporter of record. The catch is ownership: the exporter of record holds the VAT refund and the foreign-exchange collection route. If the goods carry a refund, fix the structure before the first shipment rather than discovering it at the refund stage.
How are lithium batteries and products with cells declared?
Cells shipped on their own fall under UN3480; cells packed with or contained in equipment fall under UN3481. Either way the shipment needs a UN38.3 test summary, an MSDS and a watt-hour statement, and the package must carry the lithium battery mark. Customs release and airline acceptance are separate standards, and passing one does not guarantee the other.
Where are 9610, 9710 and 9810 e-commerce shipments filed?
Retail export under 9610 uses list declaration, while 9710 for business-to-business and 9810 for overseas warehouses follow different entry logic. Express and e-commerce cargo at SZX is handled at the international express supervision center, where lists are matched against waybill, order and payment data before release. Shenchang also handles 9610 export transit.
What happens if my cargo is flagged at the gate?
Being flagged is routine enforcement, not a finding. At Shenchang the gate diverts flagged cargo to the central inspection area for inspection in the normal flow while cleared cargo goes straight to build-up. Someone has to attend for opening, counting and photographs, and X-ray is used wherever it is sufficient. Inspection itself is free; devanning, shifting and storage are billed as incurred.
Can air cargo leave China through another airport after clearing in Shenzhen?
Yes. Shenzhen operates air-to-air transit export to Urumqi, Harbin, Chengdu Shuangliu, Chengdu Tianfu, Beijing Daxing and Beijing Capital: declared in Shenzhen, exported elsewhere, one declaration and clearance at both ends. Truck flights and cross-border fast clearance at a road port are the other options, and the mix depends on destination and available space.
Is customs available for late-night flights?
Yes at Shenchang, which has run 24-hour customs clearance since April 2025, so overnight freighters pass the gate normally. The main international terminal also operates around the clock, but filing and inspection follow customs working arrangements. For a small-hours departure, file in the afternoon and leave the night for terminal handling rather than for paperwork.
When are the documents for a VAT export refund available?
The refund copy of the entry can be printed only after departure and manifest closure, usually one to three working days after the flight. Amendments, inspections or a slow manifest push that back. The exporter of record, the invoice issuer and the payment route all have to match, or the refund stage asks for an explanation.
