HTS Chapter 51 covers wool and fine or coarse animal hair, including the fibers themselves, waste, carded or combed fiber, yarn, and woven fabrics. The headings distinguish the material and processing stage—for example, raw or unprocessed wool, carded or combed fiber, yarn made from those fibers, and woven fabrics. Retail presentation and whether the yarn is carded or combed can also affect classification.
The HTS is organized from broad to specific: chapter, heading, subheading, and usually a 10-digit statistical reporting number. To classify a product, first identify its actual material and physical form, then determine how far it has been processed and how it is presented. Read the legal heading and subheading text, including notes and exclusions, rather than relying only on a product description or a search result. When the facts are unclear, a customs broker or binding ruling process may be appropriate.
What to check
- Confirm the fiber content and distinguish wool from fine or coarse animal hair; do not classify solely by the product’s trade name or intended use.
- Identify the processing stage: raw fiber, waste, carded or combed fiber, yarn, or woven fabric. For yarn, check whether it is made from carded or combed material and whether it is put up for retail sale.
- Check the relevant Chapter and Section Notes, including exclusions that may direct a product to another chapter or heading.
- For mixed-material goods or blends, verify the applicable textile classification rules and any required calculation of fiber composition.
- After selecting the 10-digit HTS code, check current official tariff data for any applicable Chapter 99 provisions, additional duties, quota or visa requirements, and other measures for the country of origin.
How to use this chapter
A chapter is the first classification level, not a duty rate. Choose the heading that describes the product, narrow by material, construction, use, or other legal distinctions, and verify the final line against the official HTS notes.
