A yarn with less than 85% cotton by weight that is packaged for retail sale and is not sewing thread falls under this heading. The 80/20 blend in your example meets both criteria — sub-85% cotton and retail presentation — so it would be classified here rather than under the 85%-or-above cotton retail yarn heading. Accurate fiber content labeling and supporting mill documentation are essential to defend this classification.

Blended cotton yarns from certain origins may be subject to antidumping or countervailing duty orders, and some synthetic-fiber components in the blend could implicate Section 301 tariffs depending on the country of origin. Importers should conduct an origin-specific trade-remedy review before sourcing, as the applicable measures depend on both the product's fiber composition and its country of manufacture.
