Step 1: Determine Hazard Classification
Everything starts with proper classification. The UN Committee assigns UN numbers and hazard classes:
- UN 2218: Acrylic Acid, Class 8 (Corrosive), PG II
- UN 1993: Flammable Liquid N.O.S., Class 3, PG II/III
- UN 3082: Environmentally Hazardous Substance, Class 9, PG III
Find this in SDS Section 14, IMO DG Code, or IATA DGR. Never guess at classification.
Step 2: Select Approved Packaging
Hazardous chemicals require UN-certified packaging bearing markings like "1A1/X/.../23/CN/XXXX". Packaging groups: PG I (high danger), PG II (medium), PG III (low).
Liquids: 200L steel/HDPE drums, 1000L IBC tanks, ISO tank containers.
Powders: 20-25kg multi-wall paper bags, 500kg jumbo bags.
Special requirements include inhibitor addition for monomers, temperature control, and nitrogen blanketing for oxygen-sensitive products.
Step 3: Prepare Dangerous Goods Declaration
Formal statement that cargo is properly classified, packaged, and labeled. Must be signed by a certified person. Includes UN number, proper shipping name, hazard class, packing group, quantity, emergency contact, and flash point.
Step 4: Book Cargo Space
Provide DG declaration, SDS, packaging certificates, and booking request. Segregation rules apply (e.g., Class 3 away from Class 5.1). Expect DG surcharges of $50-150 per TEU.
Step 5: Labeling and Marking
Every package needs primary hazard label (diamond-shaped), UN number panel, secondary hazard labels if applicable. Minimum label size: 100mm x 100mm. FCL containers need placards on all four sides (250mm x 250mm).
Step 6: Port Procedures (Export Side)
Chinese ports require pre-arrival inspection for DG cargo by CIQ. DG cargo must arrive 48-72 hours before vessel departure. Standard export customs declaration plus DG declaration copy and packaging performance certificate required.
Step 7: Track and Prepare for Arrival
Send digital copies of all documents to consignee 3-5 days before arrival for customs pre-declaration, hazardous cargo warehouse arrangement, and licensed DG carrier scheduling.
Step 8: Destination Port Handling
Expect higher inspection rates for DG cargo. Once cleared, pay port/DG handling fees, arrange pickup by licensed hazardous materials carrier, and ensure receiving facility is authorized.
Air Freight vs. Sea Freight
Air freight follows stricter IATA DGR rules, costs 5-10x more, but delivers in 3-7 days vs. 20-35 days for sea. Best for samples, high-value specialty chemicals, or emergency replacements.
