Home / Shipping To USA / Professional Shipping DG Cargo from China to USA
A complete guide for U.S. importers covering how to legally and safely ship dangerous goods (DG) from China to the United States — by air (IATA DGR), by LCL and FCL ocean (IMDG Code), and by bonded truck — including UN Class 9 lithium batteries, Class 3 flammable liquids, Class 8 corrosives and all other hazard classes. Backed by 12+ years of hazmat-compliance experience from Goodhope International Logistics.
The United States imports more than USD 4.5 billion of classified dangerous goods from China every year. China is the dominant origin for batteries, lithium-ion cells, paints, coatings, adhesives, aerosols, cleaning products, pesticides and laboratory chemicals bound for the U.S. market. All DG shipments from China are governed by the same UN classification system used worldwide — nine classes, each with strict packaging, labeling, documentation and segregation rules.
Misdeclaring or under-declaring DG can result in U.S. CBP civil penalties of up to USD 5,000 per violation per shipment, criminal prosecution under 49 U.S.C. § 5124, vessel/aircraft detention, and permanent loss of hazmat privileges. We audit every UN number, packing group and flash point before booking.
Air freight is the fastest way to move DG cargo, but it is also the most strictly regulated. Every package must comply with the IATA Dangerous Goods Regulations (DGR) — the industry rulebook published annually by the International Air Transport Association. China-to-U.S. air DG typically clears customs and delivers to the consignee within 3 to 7 days door-to-door, depending on whether the destination is a U.S. gateway airport or an inland point.
DG air freight can only be tendered by a forwarder holding a valid IATA Cargo Agency qualification and a Dangerous Goods Regulations training certificate (current within 24 months) for each staff member who signs the shipper's declaration. We operate as an IATA-licensed agent and pre-clear every consignment with the carrier's DG desk before tendering.
A signed, multi-copy Shipper's Declaration for Dangerous Goods is mandatory on every DG air shipment. It must include the UN number, proper shipping name, hazard class, packing group, quantity, packaging instruction, authorization (Special Provision or Excepted/Limited Quantity) and the 24-hour emergency contact (tremcard reference).
Each package must be built to a UN Performance Packaging (PG) standard and marked with the UN packaging code (e.g. UN 4G/Y18/S/...). For Section II lithium batteries (PI 965-970), the inner packagings must pass a 1.2 m drop test and the cells must have passed UN 38.3 testing. We supply and pre-print packaging at our Shanghai, Shenzhen and Guangzhou DG-certified warehouses.
Each package must display the appropriate Class 9 (or other) hazard label in diamond format, the handling label (e.g. "Cargo Aircraft Only" or "This side up"), the UN number, and the consignor/consignee address. Overpacks require the "Overpack" mark and a copy of all inner labels.
Standalone lithium batteries (UN3480 & UN3090) and most Class 3 liquids with flash point < 23°C are forbidden on passenger aircraft. They must travel on Cargo Aircraft Only (CAO) flights, which limits routing options and may add 1-3 days to transit time.
DG LCL is the right answer for shippers moving 1–15 CBM of dangerous cargo — too small for a full container, too dangerous to share with general cargo. China-to-U.S. DG LCL follows the IMDG Code and requires specially licensed CFS (Container Freight Station) handling at origin and destination, plus strict segregation between incompatible hazard classes inside a single container.
Consolidated weekly sailings from China to U.S. coasts with full hazmat compliance.
Classes accepted and the documentation each shipment requires.
When your DG shipment exceeds ~15 CBM, FCL is faster, cheaper and safer than LCL. You get a dedicated IMO-marked container, single shipper, single consignee, no segregation constraints, faster port handling and direct drayage to your U.S. warehouse. China-to-U.S. DG FCL transit is 18–24 days to the West Coast and 26–34 days to the East Coast.
Choose the right equipment for your hazmat.
What we handle at origin so you don't have to.
A dangerous goods shipment can only move from China to the United States when both the forwarder and the shipper hold the right qualifications, and the documentation stack is complete, accurate and audit-ready. Goodhope Freight holds the certifications below and prepares every required document for you — so you can focus on production and sales instead of paperwork.

China is the world's largest exporter of lithium-ion and lithium-metal cells, and the U.S. is its biggest single market. Lithium batteries are classified under UN Class 9 (Miscellaneous Dangerous Goods) and must be declared correctly under one of four UN numbers depending on cell type and how it is packed. Standalone cells face the strictest rules; cells packed in or contained in equipment have more flexible options.
UN3480 / UN3090 standalone cells must travel Cargo Aircraft Only. Typical transit: 3–6 days door-to-door from China to U.S. gateway (LAX, JFK, ORD, ATL). IATA Section II (PI 965-970) relaxed requirements for small cells ≤ 10 kg net Li-equivalent.
IMDG Special Provision 188 allows most lithium cells under IMDG provisions with simplified packaging. Ocean is the safest and most cost-effective mode for large volumes of batteries — we book with carriers that accept lithium under SP 188 / 230.
Amazon FBA accepts Class 9 lithium-ion only when packed in equipment (UN3481) and pre-approved via the FBA Dangerous Goods program. Standalone power banks (UN3480) are restricted. We pre-clear every ASIN and ensure correct SDS upload.
Dry ice for temperature-controlled lithium shipments, magnetized material, life-saving appliances, and lithium battery-powered equipment all fall under Class 9. We prepare Section II / Section I packaging and labels per IATA PI 954 (dry ice).
Not every container line, and not every China airport, will accept dangerous goods. Below is the carrier and gateway landscape we work with every week. We pre-book space on DG-accepted vessels and flights to keep your shipment moving without rejection or reroute fees.
