Written to help non-specialists understand this page. Rates, dates, and legal facts come from the official records above and on the linked source.
HTS heading 5309 is a broad product category for woven fabrics made from flax fibers. It groups textile fabrics in which flax is the relevant fiber, rather than identifying one exact fabric, use, or duty treatment. The heading can cover different fabric constructions and fiber compositions, subject to the detailed tariff wording and legal notes.
To reach the specific 8-digit HTSUS code, start with the heading and then read the subheadings and statistical provisions beneath it. These narrower provisions commonly distinguish the fabric by factors such as whether it is made wholly or partly of flax, the percentage or description of other fibers, and the fabric’s type or construction. Confirm the exact wording, unit of quantity, and any applicable notes in the current official HTSUS before filing.
What to check
- Confirm that the product is woven fabric and that flax is classified as the relevant textile material; do not assume a flax-blend fabric is treated the same as a flax-only fabric.
- Obtain the fiber-content breakdown, preferably from the mill or manufacturer, and compare it with the subheading distinctions.
- Check the fabric’s construction and description, including any features identified by the tariff provisions, rather than relying only on the commercial product name.
- Read the complete 8-digit provision and its legal notes, including any exclusions or special definitions, in the current HTSUS.
- Keep product specifications, laboratory or supplier documentation, and samples available; request a binding classification ruling or consult a customs broker when the wording 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.
