HTS heading 2834 is a four-digit product category for nitrites and nitrates, which are chemical compounds containing nitrite or nitrate ions. It groups these products at a broad level; the heading itself is not usually the complete classification needed for an import entry.
To reach the correct 8-digit HTSUS code, narrow the product using the applicable subheading descriptions and any required distinctions, commonly the chemical identity or type of compound. Confirm the product’s composition, form, and any relevant legal notes, and use the full 8-digit description that most precisely matches the merchandise. If the product is a mixture, preparation, solution, or formulated product rather than a single chemical compound, classification may require additional analysis.
What to check
- Identify the exact chemical name, formula, and whether the product is a nitrite, nitrate, mixture, solution, or preparation.
- Compare the product’s composition and chemical type with every relevant 8-digit subheading under heading 2834.
- Check the HTSUS legal notes, unit of quantity, and any exclusions or product-specific conditions that affect classification.
- Use the safety data sheet, specification sheet, certificate of analysis, and commercial invoice to support the classification.
- Request a customs-broker review or binding ruling when the chemical identity, mixture status, or competing headings is uncertain.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
