Last updated: April 2026 dataDyed synthetic-fiber knit fabrics occupy a critical position in the apparel supply chain, serving as finished-color inputs for garment cut-and-sew operations in sportswear, intimate apparel, and outerwear. The US schedule subdivides this heading by fiber type and construction, with dedicated lines for dyed nylon double-knit (6006320020), dyed polyester double-knit (6006320040), other dyed double-knit synthetics (6006320060), and remaining dyed synthetic knits (6006320080). China leads US supply, with South Korea and Canada also among the top sources. Section 301 exposure on Chinese-origin goods makes supplier diversification — including toward South Korea — a recurring strategic consideration for fabric buyers.

Customs entries for knit fabrics generally require a commercial invoice stating fiber composition by weight percentage, a packing list, and often a mill certificate or laboratory test report confirming fiber content. Accurate fiber identification is essential because misclassification between synthetic and artificial fibers can result in different duty rates and potential penalties.
The US tariff lines under 600632 explicitly separate double-knit/interlock constructions from other knit structures. Double-knit fabrics have distinct physical properties — greater stability, weight, and reversibility — that affect end-use suitability and can influence duty treatment. Importers should confirm knit construction with their supplier and reflect it accurately on entry documents.
