Last updated: July 2026 dataThree- and four-thread twill constructions of polyester-cotton blends — with polyester under 85% by weight and fabric weight at or below 170 g/m² — are classified under the single US tariff line 5513120000. The twill weave structure distinguishes this heading from the plain-weave fabrics of heading 551311, and the construction is commercially associated with workwear, chino, and uniform fabrics where diagonal weave durability is valued. Pakistan and India are the leading US suppliers, with China also a significant source subject to Section 301 tariffs. As with other subheadings in this group, both the fiber weight ratio and the fabric weight per square meter must be confirmed before classification.

Heading 551312 is specifically reserved for 3-thread (including broken twill) and 4-thread twill weaves in the polyester-cotton blend, under-85%-polyester, unbleached-or-bleached, ≤170 g/m² category. Plain-weave fabrics with the same fiber and weight parameters fall under 551311, while other weave constructions (satin, etc.) would fall into the 'other' subheadings. Weave structure documentation from the mill — specifying the interlacing pattern — is essential to support the correct classification.
Mexico is a leading supplier under this heading, and goods of qualifying Mexican origin may be eligible for USMCA preferential treatment. However, textile and apparel goods face specific USMCA rules of origin — typically a 'yarn-forward' requirement — meaning the polyester and cotton yarns used to weave the fabric must also originate in a USMCA country for the fabric to qualify. Importers should obtain a USMCA certification of origin and verify the yarn sourcing before claiming preference.
