Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other simple sulfides like zinc or calcium variants
Heading 2830 covers sulfides of other metals, excluding sodium-specific subheading.
If sodium hydroxide impurity exceeds classification thresholds
High NaOH content may classify as sodium hydroxide under 2815 per purity rules.
