HTS US: 2841.XX.XXXX
Description
Heading 2841 encompasses a range of chemical salts formed from oxometallic or peroxometallic acids. These substances are primarily used in industrial, chemical, and manufacturing processes due to their oxidizing properties and applications in pigments, catalysts, and other chemical syntheses.
The heading specifically includes various chromates and dichromates, permanganates, molybdates, tungstates (wolframates), and other related salts. These compounds are often characterized by their metal content and oxidation states, and they are vital in sectors such as leather tanning, water treatment, and metal plating.

What is NOT Classified Here?
To ensure accurate classification, note these exclusions:
- Pure elemental metals and their alloys are classified in other headings under Chapter 72 or 74.
- Organic metal compounds or organometallic complexes are excluded and fall under different chapters.
- Oxides and hydroxides of metals without salt formation under oxometallic or peroxometallic acids belong elsewhere.
Notes
- Regulatory Compliance: Many of these salts, especially chromates and permanganates, are regulated due to their toxicity and environmental impact.
- Duty Rates: Import duties vary depending on the specific 10-digit code and country of origin. Some compounds may be subject to special trade restrictions or environmental controls.
- Usage Considerations: These compounds are often handled under strict safety protocols in industrial settings.
