HTS heading 2613 is a four-digit product category for molybdenum ores and concentrates. It generally covers mineral material containing molybdenum that has been extracted and prepared as ore or concentrate, rather than refined molybdenum metal or finished molybdenum products. The heading may distinguish products by processing or type, such as roasted versus unroasted material.
To reach the correct 8-digit HTSUS code, start with the heading and then follow the more specific subheading descriptions under it. Confirm the material’s physical form, processing status, composition, and intended identity as an ore or concentrate. The final statistical suffix can depend on the detailed product description in the current HTSUS, so do not select a code based only on the word “molybdenum.”
What to check
- Obtain the supplier’s technical description, assay or laboratory data, and processing details before classifying the shipment.
- Confirm whether the product is an ore or concentrate and whether it has been roasted, treated, or otherwise processed.
- Read every subheading and statistical suffix under heading 2613 in the current HTSUS; do not stop at the four-digit heading.
- Compare the product’s composition and form with the official wording, explanatory materials, and any relevant classification guidance.
- Ask a customs broker or request a binding classification ruling if the product’s processing or composition could fit more than one description.

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.
