HTS heading 4006 groups together certain products made of unvulcanized rubber that are already formed into shapes or articles, rather than being imported as basic rubber compounds. Examples include rods, tubes, profile shapes, discs, and rings. The key distinction is that the rubber has not yet been vulcanized, meaning it has not undergone the curing process that gives finished rubber much of its permanent elasticity and strength.
Heading 4006 is a 4-digit category, not usually the complete classification. To reach the correct 8-digit HTS code, follow the subheading structure and compare the product with the listed material or product-type descriptions. The relevant distinction may involve the rubber composition, such as whether it is cellular or noncellular, or the particular form or article. Confirm that the goods belong in heading 4006 before choosing among its more specific subheadings; vulcanized rubber products may belong elsewhere.
What to check
- Verify from product specifications that the rubber is unvulcanized, and ask the supplier whether any curing or vulcanization has occurred.
- Identify the exact physical form, such as a rod, tube, profile shape, disc, ring, or another article, and record its dimensions and production method.
- Check the material description carefully, including whether the rubber is cellular, mixed with other materials, or combined with textile, metal, plastic, or other components.
- Read the HTS subheadings in order and match the product to the most specific material and type description; do not stop at heading 4006.
- Keep technical sheets, photographs, composition information, and supplier statements, and seek a customs broker or binding-ruling guidance when the material or manufacturing status is unclear.

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 4006?
Other forms (for example, rods, tubes and profile shapes) and articles (for example, discs and rings), of unvulcanized rubber. 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.
