HTS heading 5306 is the 4-digit category for flax yarn, commonly associated with linen yarn. It groups yarn made from flax fibers, rather than finished woven or knitted fabric. The heading generally covers yarn whether sold for textile production, sewing, or another use, but the product must meet the tariff meaning of flax yarn.
To reach the correct 8-digit HTS code, first confirm that the item belongs in heading 5306, then follow the more detailed subheading descriptions. A key distinction is usually the yarn’s construction, such as single yarn versus multiple, folded, or plied yarn. The complete 8-digit description may also depend on additional characteristics stated in the current HTS, so classification should be based on the exact tariff wording rather than the product’s marketing name alone.
What to check
- Confirm the fiber content and verify that flax is the relevant textile fiber; do not assume that every product marketed as linen is classified as flax yarn.
- Determine whether the yarn is single, multiple, folded, or plied, and document how it is constructed.
- Check whether the item is actually yarn rather than thread, fabric, cordage, or a finished article; similar-sounding products can fall under different headings.
- Read the current HTS provisions, including section and chapter notes, and compare the full 8-digit descriptions before selecting a code.
- Keep specifications, labels, invoices, and technical sheets; seek a customs broker or formal classification ruling when the construction or fiber content 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.
