07 Supply & export note
Caustic soda is strongly hygroscopic and will absorb moisture and carbon dioxide through inadequate packing. We specify sealed inner-liner bags for all sea freight and advise against unlined packing regardless of cost saving. Hazard documentation is prepared for every consignment.
