Moisture-Proof Bulk Packaging, Safe Storage and Maritime Shipment Rules for Ammonium Lignosulfonate Export

Ammonium Lignosulfonate is a hygroscopic organic powder prone to agglomeration under humid conditions, requiring standardized moisture-proof packaging, warehouse storage and general cargo shipping operations for cross-border export. It belongs to non-dangerous goods, bringing low customs clearance difficulty with complete supporting documents.

 

Standard export packaging for Ammonium Lignosulfonate adopts 25kg woven bags lined with PE plastic film or 1000kg ton jumbo bags. Double-layer sealing blocks sea moisture during long ocean voyages, preventing powder clumping and performance decline before arriving at destination warehouses. Outer bags mark product grade, moisture index and production batch for easy port inspection.

 

Warehouse storage of Ammonium Lignosulfonate demands cool, dry and well-ventilated indoor space. Packages must stay away from ground dampness and acidic chemical stacks to avoid chemical neutralization and mold growth. Stack height should be controlled below 8 layers to prevent bottom bag rupture and powder leakage.

 

Maritime shipment rules are simple for this product: no IMDG dangerous goods declaration is needed. Exporters only prepare MSDS, COA, packing list and commercial invoice for smooth customs clearance. Loading and unloading staff just wear dust masks to avoid long-term inhalation of fine lignin powder. Proper packaging and storage guarantee Ammonium Lignosulfonate retains stable dispersion and binding effects after global transit.
