HS-4 · Heading
2841 — Salts of oxometallic or peroxometallic acids
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2841 when importing salts of oxometallic or peroxometallic acids, such as sodium dichromate used in tanning leather or as a pigment. This heading covers various salts, including chromates and molybdates, which have specific applications in industries like manufacturing and agriculture.
When choosing between HS-6 lines, consider the specific salt type. For example, HS-6 284130 specifically identifies sodium dichromate, while HS-6 284150 covers other chromates and dichromates not specified elsewhere. Ensure your product matches the description to avoid misclassification.
If your product is potassium permanganate, you would use HS-6 284161. However, if it’s a different manganite or manganate, check HS-6 284169 for other variations. The distinction is crucial for accurate tariff application and compliance.
For salts like molybdates, refer to HS-6 284170. If your product doesn't fit neatly into the other categories, you might need HS-6 284190, which covers salts not elsewhere classified in this heading.
