Calcium hypophosphite can be used as a halogen-free flame retardant in polyphenol oxidizers (PA), a food additive, and an animal feed additive. It can partially replace aluminum diethylphosphinate in PA flame retardant formulations. It is classified as a Class 4.1 hazardous chemical in my country's chemical catalog. What issues should be considered when exporting it to other countries and regions?

1. It must be transported to the warehouse using hazardous chemical vehicles throughout the entire process, and the packaging bags must have clear GHS labels. A maritime inspection certificate is required for export. No commodity inspection is required, but a hazardous packaging certificate is necessary.

2. It is a phosphorus-containing inorganic salt, and the export tax rebate rate is 0%.

3. Calcium hypophosphite related codes: HS No. 2835100000, CAS No. 7789-79-9, English name: Calcium hypophosphite, chemical formula: Ca(H2PO2)2

4. Packaging is 25kg/bag, double-layered: the first layer is an aluminum foil bag, and the second layer is a paper-plastic composite bag. 700kg/pallet, 1CBM/pallet, 14 tons/FCL

Calcium hypophosphite has a certain degree of solubility and can absorb moisture in humid environments or after prolonged exposure to air. Therefore, if the packaging bag is found to be damaged during storage, transportation, or handling, please seal it immediately; otherwise, the product will absorb moisture and become ineffective.
