Packaging, Storage & Transportation

1. Packaging Specifications

• Large quantity packaging: 1000kg / Ton bag (flexible freight bag), suitable for large-scale industrial orders, convenient for forklift loading and unloading.
• Customized packaging: Can print customer logos, product information, safety prompts, etc., to meet brand promotion needs.

2. Storage Requirements

• Moisture-proof: Avoid direct contact with air, seal the bag tightly after use, and place it on a wooden pallet (10-15cm above the ground) to prevent ground moisture.
• Anti-contamination: Separate storage from strong acids, strong alkalis, oxidants and other chemicals to avoid chemical reactions.
• Shelf life: 24 months under proper storage conditions (unopened packaging), if the packaging is damaged, it should be used as soon as possible.

3. Transportation Guidelines

• Transportation precautions: Cover with rainproof cloth during transportation to prevent rain and moisture; avoid violent loading and unloading to prevent bag breakage and product leakage; do not mix with toxic and harmful goods to avoid contamination.
• Cross-border transportation: Provide complete export documents (including COA, MSDS, customs declaration form, commodity inspection certificate, etc.), support FOB/CIF/EXW and other trade terms, and can cooperate with professional chemical logistics companies to ensure the safety of goods transportation.
