HTS heading 3925 is a broad product category for builders’ ware made of plastics that is not more specifically classified elsewhere. It generally covers certain construction-related plastic articles, such as building components and fittings, rather than plastic material sold only as sheets, film, tubes, or other basic forms. The exact scope depends on the product’s design, function, and how it is presented at import.
To reach the correct 8-digit HTSUS code, first confirm that heading 3925 applies instead of another heading. Then use the subheadings and statistical provisions to narrow the item by its type or construction function—such as a specified building component, fitting, or other covered article—and, where the tariff text provides it, by the plastic material or other stated characteristic. Review the legal notes, product descriptions, and any applicable exclusions; the final classification may require a customs broker or other qualified professional.
What to check
- Describe the item’s construction use, shape, dimensions, and method of installation before comparing tariff provisions.
- Confirm that the product is builders’ ware and is not more specifically classified as plastic in a basic form, a household article, a sanitary or plumbing article, or another named product.
- Read every subheading and statistical suffix within heading 3925; do not choose a code based only on a product name or marketing description.
- Identify the plastic material and any reinforced, assembled, or composite construction when the tariff wording asks for those details.
- Keep product specifications, photographs, technical drawings, and supplier information to support the classification decision, and seek broker advice for borderline cases.

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.
