Sodium Hydrosulfide Flake Alternative (Na2S Equiv.)
Sodium hydrosulfide (NaHS) flakes sometimes traded as sodium sulfide equivalent for mining flotation. Strictly Na2S under HTS 2830.10.00.00 when declared as such. Used interchangeably in some applications.

Import Tips & Compliance
• Careful chemical analysis needed; NaHS properly 2830.20 but misdeclared as Na2S common
• MSDS must match declared composition exactly
• Customs may require lab verification for borderline sulfide classifications
