HTS heading 7501 is a broad product category for intermediate materials made during nickel metallurgy. It covers nickel mattes, nickel oxide sinters, and other partly processed nickel products that are not yet finished nickel articles or ordinary unwrought nickel. The heading describes the material’s metallurgical form and stage of processing, not simply the fact that it contains nickel.
To reach the correct 8-digit HTS code, first confirm that heading 7501 fits the product, then use the lower-level subheadings and statistical suffixes. These distinctions commonly depend on the product’s material or type, such as matte, oxide sinter, or another specified intermediate product. Review the product’s composition, manufacturing process, physical form, and technical description against the current HTSUS wording. If the product could fit another nickel heading, a customs broker or classification specialist may need to assess the facts.
What to check
- Obtain the supplier’s full technical description, including chemical composition, nickel content, and any relevant impurities.
- Confirm how the product was made and whether it is a matte, oxide sinter, or another intermediate of nickel metallurgy.
- Check the product’s physical form and intended processing stage; do not classify it based only on its trade name.
- Read every subheading and statistical suffix under heading 7501 in the current HTSUS, and compare the wording with the commercial invoice and specifications.
- Request a binding ruling or professional classification advice when the product description is incomplete or could fit more than one heading.
HTS heading 7501 summary
Nickel mattes is a 4-digit product category containing 2 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
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.

Common questions
What products fall under HTS heading 7501?
Nickel mattes, nickel oxide sinters and other intermediate products of nickel metallurgy. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
