HTS Chapter 54 generally covers man-made textile filaments and products made from them. It includes sewing thread, synthetic or artificial filament yarn, certain monofilaments and narrow strips, and woven fabrics made from synthetic or artificial filament yarn. “Synthetic” generally refers to fibers made from polymers produced by chemical synthesis, while “artificial” generally refers to fibers made from regenerated or chemically modified natural polymers. The exact fiber composition and product construction matter more than the product’s marketing name or intended use.
The HTS is organized hierarchically: the chapter is the two-digit section of the tariff (54), the heading is the next four digits (such as 5402 or 5407), the subheading adds digits to describe more specific goods, and the complete U.S. classification normally ends in a 10-digit statistical reporting number. To classify a product, start with its physical facts—fiber type, filament or yarn form, construction, dimensions, finishing, and whether it is woven—then compare those facts with the heading and subheading descriptions and their legal notes. Classification can depend on technical details, so a customs broker or other qualified professional may be needed for difficult cases.
What to check
- Identify the exact fiber material and confirm whether it is synthetic or artificial; obtain supplier specifications, fiber percentages, and technical sheets.
- Determine the product form and construction: sewing thread, yarn, monofilament, narrow strip, woven fabric, or another article, and verify measurements such as decitex, width, and fabric structure.
- Read the heading, subheading, section notes, and Chapter 54 notes together; check whether an exclusion or a more specific provision elsewhere in the HTS applies.
- Do not classify solely by end use or product name; compare the actual materials and manufacturing characteristics with the tariff language.
- After selecting the base HTS provision, check current U.S. notes and Chapter 99 provisions for any additional duties, exclusions, quota measures, or other reporting requirements that may apply to the origin and product.
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.
