Last updated: August 2026 dataPiece-dyed synthetic warp-knit fabrics are a workhorse input for activewear, swimwear, lingerie, and automotive interior textiles, and South Korea and China together account for the bulk of US imports under this heading. The US schedule subdivides by construction: open-work (6005370010), stitch-bonded (6005370020), a general line (6005370000), and a residual NESOI line (6005370080). Vietnam and Mexico are also notable suppliers, and goods from Mexico may benefit from USMCA preferential treatment where rules of origin are satisfied.

Open-work fabrics have clearly visible holes or gaps in the structure that are an intentional part of the design — mesh, net, or lace-like constructions. A fabric with a solid, closed knit structure, even if lightweight, would not qualify as open-work. Physical examination of the fabric, supported by a mill specification sheet describing the construction, is the standard approach; CBP may request samples or technical documentation during review.
Imports of synthetic warp-knit fabrics from China are subject to Section 301 tariffs in addition to the normal column 1 duty rate. The applicable list and rate depend on the specific 10-digit HTS classification and any subsequent modifications or exclusions. Importers should verify current Section 301 status for the relevant tariff line with CBP or a licensed customs broker before finalizing landed-cost calculations, as rates and exclusion lists are subject to change.
