What are the key logistics and regulatory challenges for exporting barium chloride from China?
Barium chloride is classified as a Class 6.1 toxic substance under UN 1564, and its export from Chinese ports requires strict dangerous goods handling. Shippers must navigate vessel selection, as not all carriers accept Class 6.1 cargo, and some require letters of indemnity even though the product is not on the Yangtze River Protection Law prohibition list. Packaging is typically 25 kg bags with packing group III, and loading must occur at certified warehouses with proper ventilation and spill containment. The HS code is 2827392000, and documentation must include composition, CAS number, and proper shipping name 'Barium compound, N.O.S.' Transport regulations prohibit mixing with acids or food-grade chemicals, and vehicles need emergency response equipment. Port-specific expertise matters, as Shanghai-based forwarders note that booking success and cost efficiency vary significantly by route and carrier familiarity with toxic solids.
