HTS heading 5402 is a four-digit product category for synthetic filament yarn other than sewing thread, when the yarn is not put up for retail sale. It also covers certain synthetic monofilament measuring less than 67 decitex. “Synthetic” generally refers to man-made fibers produced from chemical polymers, while “filament” means the fibers are continuous rather than short staple fibers.
Heading 5402 is only the starting point, not the complete classification. To select an 8-digit HTS code, follow the subheadings and statistical subdivisions that distinguish the yarn by features such as the fiber-forming material, whether it is textured or non-textured, whether it has high tenacity, its yarn construction, and other technical characteristics. Confirm the product’s exact specifications against the current HTS descriptions and any applicable classification guidance; a customs broker or classification specialist may be needed for borderline products.
What to check
- Confirm that the product is synthetic filament yarn, not natural-fiber yarn, staple-fiber yarn, or sewing thread.
- Verify that the goods are not put up for retail sale, including how they are packaged and marketed.
- Identify the fiber-forming material or polymer and obtain the supplier’s technical specification or fiber-composition statement.
- Check whether the yarn is monofilament, multifilament, textured, non-textured, high-tenacity, or otherwise specially described.
- Compare every relevant characteristic with the 8-digit subheadings and retain product literature, test data, and classification reasoning for your records.

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.
