HTS heading 3904 is a broad product category for polymers made from vinyl chloride or other halogenated olefins, presented in “primary forms.” These are usually basic resin materials—such as powders, granules, flakes, or similar bulk forms—used to make finished plastic products. The heading is not limited to one polymer or one end use; it groups several related materials that must be separated at more detailed tariff levels.
To reach the correct 8-digit HTSUS code, first identify the polymer’s chemical identity and then follow the subheadings for the relevant material or type. Classification may depend on distinctions such as whether the product is PVC or another halogenated polymer, whether it is a copolymer, and whether it is supplied in a specified primary form. Review the product’s technical data sheet, formulation, and physical presentation, then verify the wording and any applicable section or chapter notes in the current HTSUS. A customs broker or classification specialist may be needed when the composition or tariff distinctions are unclear.
What to check
- Confirm the product is a polymer of vinyl chloride or another halogenated olefin, rather than a different plastic covered elsewhere.
- Check the technical data sheet for the exact polymer, copolymer status, additives, and composition—not just the product’s trade name.
- Verify that the goods are in a qualifying primary form, such as resin granules, powder, or flakes, rather than a finished or shaped article.
- Read the 6-digit and 8-digit subheading descriptions and related legal notes to match the material or type precisely.
- Keep supplier specifications, formulation information, and classification reasoning on file, and seek broker advice if the product could fit more than one subheading.
HTS heading 3904 summary
Polymers of vinyl chloride or of other halogenated olefins is a 4-digit product category containing 3 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 3904?
Polymers of vinyl chloride or of other halogenated olefins, in primary forms. 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.
