Frequently Asked Questions

1. What physical forms of Sodium Hydrosulfide are suitable for long-distance ocean transportation?

Granular and flake types of Sodium Hydrosulfide are more suitable for long-distance shipping. These two forms feature low moisture absorption, stable physical structure and less leakage loss during container transportation, effectively reducing storage and transportation risks for overseas importers.

2. Does this Sodium Hydrosulfide support REACH compliance and MSDS download?

All batches of Sodium Hydrosulfide complete formal REACH registration to meet EU chemical import regulations. Standard safety documents are available for free MSDS download, covering chemical hazard identification, transportation requirements and emergency disposal guidelines.

3. What storage conditions are required for industrial grade Sodium Hydrosulfide?

Industrial grade Sodium Hydrosulfide needs to be stored in dry, ventilated and cool warehouses. Sealed packaging is necessary to avoid contact with humid air. Direct contact with strong acids and oxidants should be forbidden to prevent chemical decomposition and harmful gas emission.
