U.S. imports of woven polyester-cotton blend fabrics, under 85% polyester, unbleached or bleached, plain weave, ≤170 g/m² (HS 551311) totaled $232K in April 2026, traded with 8 countries.
Last updated: April 2026 dataPlain-weave fabrics blending polyester staple fibers with cotton — where polyester is under 85% by weight and the fabric does not exceed 170 g/m² — are a foundational input for shirting, uniform, and institutional textile applications. The US schedule subdivides this heading by end-use construction: 5513110020 for plain-weave poplin and broadcloth, 5513110040 for sheeting, 5513110060 for printcloth, and 5513110090 for cheesecloth and similar open constructions. Pakistan leads US supply under this heading, with Mexico and India also significant sources; imports from China carry Section 301 tariff exposure. The weight ceiling of 170 g/m² is a hard classification boundary — fabrics exceeding this threshold fall into a different subheading — making fabric weight certification a routine documentation requirement.

Fabrics exceeding the 170 g/m² weight threshold do not qualify under heading 551311 and must be classified in the appropriate higher-weight subheading within Chapter 55. Importers should obtain fabric weight test reports from an accredited laboratory before filing entry, as CBP may request weight certification during examination, and reclassification to a higher-weight line can affect the applicable duty rate.
The polyester staple fiber content must be under 85% by weight, with cotton making up the balance (or the majority of the remaining fiber). Mill certificates or fiber content test reports — typically conducted per AATCC or ISO fiber analysis standards — are the standard supporting documents. If the polyester content is at or above 85%, the fabric reclassifies to heading 5512, which carries different duty treatment.
