Fireworks move as Class 1 dangerous goods in full containers (FCL) only — LCL is not accepted for 1.3G and impractical for 1.4G. Your supplier arranges licensed DG trucking to Shanghai, Ningbo or Shenzhen, files the DG declaration, MSDS and packaging certificate, and books with a carrier that accepts Class 1 cargo (book 2–3 weeks ahead; surcharges apply). Air freight and China–Europe rail are not available for fireworks.

For pyrotechnic products the practical MOQ is one 20-foot container — you can usually mix SKUs inside it. Cold-spark machines and other non-pyrotechnic hardware can ship in smaller quantities (even by air), but their consumable granules still move by sea as DG. Custom show services are quoted per event, not per container.

An EX Number is the US DOT/PHMSA explosives approval required before fireworks can be transported to or through the United States. The manufacturer applies through an authorized fireworks approval laboratory (e.g. AFSL’s lab) and receives approval letters per product family. As a buyer, request the EX letter schedule for every SKU on your order and cross-check it against the packing list before the container closes.

Video sampling is the industry standard: the factory shoots numbered test videos of your selected items so you can judge effect height, break and timing. Physical samples can ship as small DG consignments but cost is high. Before bulk shipment, commission a pre-shipment inspection or third-party audit (SGS/BV) — and factory visits are welcomed by established exporters.

Each regime is verifiable: AFSL membership via the AFSL office; EX letters against the issuing approval laboratory; CE Declarations of Conformity via the notified-body number on the EU NANDO database; ISO 9001 certificates via the issuing certification body. Also check the CPSC public recall database for the supplier’s history.

Standard terms are 30% T/T deposit and 70% against the bill-of-lading copy; letters of credit are accepted for larger programs. Production runs 45–75 days depending on season — book earlier for July-4 (ship by May) and New Year (ship by November) programs. Incoterms are usually FOB Shanghai/Ningbo or CIF destination.
