HTS heading 8101 is a broad product category for tungsten, also called wolfram, and articles made from it. It can include the metal in different forms, such as unwrought material, powders, worked products, and manufactured articles, as well as tungsten waste and scrap. The heading is a starting point, not the final classification.
To reach the correct 8-digit HTSUS code, first identify what the product is and how it is presented: for example, raw material, powder, wire, bar, tool component, finished article, or waste and scrap. The relevant subheading may depend on the product’s physical form, composition, processing, or intended use. Read the complete heading and subheading descriptions, along with the legal notes and applicable classification rules, rather than choosing a code based only on the product name.
What to check
- Describe the item precisely, including its form, dimensions, manufacturing process, tungsten content, and intended use.
- Separate waste and scrap from usable tungsten material or finished articles; verify how the tariff provisions define those terms.
- Review every subheading under heading 8101 and compare the wording with the product’s actual condition and composition.
- Check whether another HTSUS heading more specifically describes a finished machine part, tool, or other article before using heading 8101.
- Confirm the classification with official HTSUS notes and, when the facts are uncertain, obtain advice from a qualified customs broker or classification specialist.

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.
