Last updated: April 2026 dataWoven fabrics where synthetic staple fibers other than polyester and acrylic/modacrylic — such as nylon or polypropylene staple — constitute 85% or more of the weight in unbleached or bleached condition are captured here, making this a residual but commercially important heading for specialty technical textiles. The US schedule subdivides by construction: 5512910010 for plain-weave and broadcloth, 5512910020 for sheeting, 5512910040 for cheesecloth and similar open constructions, 5512910060 for satin and twill weaves, and 5512910090 for other constructions. South Korea leads US supply, followed by China — which carries Section 301 exposure — with the United Kingdom and Taiwan also notable sources. Nylon staple fiber fabrics used in filtration, geotextile, and industrial applications are a common commercial driver for this heading.

Heading 551291 covers woven fabrics where the dominant synthetic staple fiber is neither polyester nor acrylic/modacrylic — common examples include nylon (polyamide), polypropylene, and polyvinyl alcohol staple fibers.

Confirming the specific fiber type on the mill certificate is essential before assigning this heading.
South Korea is a US free-trade-agreement partner under KORUS, which means qualifying goods of South Korean origin may be eligible for preferential duty treatment, provided the applicable rules of origin are satisfied and a valid certificate or certification of origin is maintained. Importers should work with a licensed customs broker to confirm origin qualification before claiming KORUS benefits.
