Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stabilized with organic substances like starch
Chapter Note 2 excludes organically stabilized dithionites/sulfides from 2830.
If elemental sulfur content dominates
Pure sulfur classifies in 2802, not compounds.

Import Tips & Compliance
• Include COA with sulfur content verification to avoid 2830.50 reclassification
• 25kg bags on pallets; ensure UN-approved packaging
• Watch for cyanide impurities from manufacturing that trigger 2837 review
