HTS heading 4002 is a four-digit category for synthetic rubber and certain oil-derived factice, when presented in primary forms or as plates, sheets, or strip. It also covers mixtures of natural rubber or other products of heading 4001 with products of heading 4002, in those same forms. “Primary forms” generally means basic, unworked forms such as liquid, paste, blocks, lumps, powders, granules, or similar forms, depending on the applicable tariff language.
To reach the specific eight-digit HTSUS code, first identify whether the product is synthetic rubber, factice, or a mixture involving heading 4001 material. Then follow the indented subheadings, which commonly distinguish the chemical or rubber type and may further distinguish the product’s form or composition. Confirm the complete eight-digit description in the current HTSUS and use the product’s technical documentation; a customs broker or classification specialist may be needed for complex compounds or borderline products.
What to check
- Identify the product’s exact polymer, chemical type, and whether it is factice or a mixture.
- Confirm whether the material is in a covered primary form, plate, sheet, or strip; do not classify solely from the product’s trade name.
- Check whether any natural rubber or other heading 4001 material is mixed with the heading 4002 product.
- Review the relevant subheading notes and the complete eight-digit descriptions in the current HTSUS.
- Compare the tariff description with the technical data sheet, formulation, manufacturing process, and invoice description; seek broker advice if those records do not clearly support one code.
HTS heading 4002 summary
Synthetic rubber and factice derived from oils is a 4-digit product category containing 6 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.
