HS-6 · Subheading
283190
Dithionites and sulphoxylates; other than sodium
Heading 2831 — Dithionites and sulphoxylates
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283190 when importing or exporting dithionites and sulphoxylates, specifically those that are not sodium-based. For example, if you're shipping a chemical used in textile processing that contains dithionite, this code applies.
This code falls under the broader category of inorganic chemicals, specifically within the 2831 heading that deals with dithionites and sulphoxylates. Unlike HS-6 283110, which covers sodium dithionite, this code is for other types, such as calcium or ammonium dithionites.
When classifying products, it's important to note that HS-6 283190 encompasses various non-sodium dithionites used in applications like bleaching, reducing agents in chemical reactions, or as intermediates in organic synthesis.
If you have a product that contains dithionites but is not sodium-based, ensure you check the specific chemical composition to confirm this classification. This can help avoid potential customs issues.
