Dangerous goods are classified into a total of 9 categories, with flammable liquids falling under Category 3. Common examples include alcohol, paints, coatings, resin solvents, gasoline, diesel fuel, and more. Today, we’ll dive deep into an export case involving UN1268 lighter fuel—covering everything from booking space and obtaining the dangerous goods packaging certificate to crucial tips for customs declaration and inspection. This comprehensive guide will ensure you avoid unnecessary detours and navigate the process smoothly.

Preparatory Work

• Hazardous Characteristics Classification and Identification Report: Issued by a CMA/CNAS-accredited institution, clearly specifying the UN number, hazard class, packing group, and other relevant information.

• Certificate of Inspection for Packaging Used in the Transport of Dangerous Goods (Dangerous Goods Packaging Certificate): To be used together with the packaging performance test report, ensuring a one-to-one match among "Item Name, UN Number, and Packaging Category."

• Material Safety Data Sheet (MSDS): Contains 16 sections; the English version must be translated by an agency approved by China Customs.

Book a shipment

• Time requirement: 10 business days in advance.

• Core task: Submit the dangerous goods certificate, MSDS, and shipping manifest to the shipping company (clearly indicating "Chinese and English product names + UN number + CLASS").

Maritime Declaration

• Time requirement: 7 business days in advance.

• Core Task: Submit the "Dangerous Goods Declaration" through a single window, upload the packing list and a copy of the terminal receipt. After review and approval by the Maritime Bureau, the "Cargo Declaration Form" will be issued.

Customs Declaration

• Time requirement: 3 days before departure.

• Core task: Submit documents such as the customs declaration form, invoice, contract, and “Authorization Letter” (an electronic agreement must be signed in advance through the Single Window platform).

Packing and Importing to Port

• Time requirement: 48 hours before departure.

• Core Task: Loading must be supervised by personnel holding a "Dangerous Goods Supervision Qualification Certificate." Containers must be labeled with hazard markings (size no smaller than 10 cm × 10 cm) and marine pollution labels, as applicable.

Other precautions

• Packaging requirements: Class 3 hazardous materials must be categorized based on flash point and viscosity, and packaging conforming to UN specifications must be used.

• Direct loading requirements: For exports from certain ports like Shanghai Port, shipside direct loading may be required, necessitating advance coordination of inspection schedules.

• Consolidation requirements: If using LCL (less-than-container load), please note the minimum cubic volume limit, and ensure that the cargo complies with the regulations of the LCL carrier.

• System Operation Guidelines: The Single Window requires "card-based login"; please obtain your electronic port IC card in advance.

Exporting hazardous materials isn’t complicated—just make sure to handle “document preparation” and “packaging compliance” upfront. If you still feel confused, or if you run into issues like tight shipping space or inspection challenges, don’t hesitate to reach out to me anytime!
