Last updated: July 2026 dataThrown silk yarn reeled from intact cocoons — as opposed to yarn spun from waste fiber — and packed in bulk or industrial form rather than retail quantities is the product covered here. China dominates global silk yarn production and leads US imports under this heading; Italy and Switzerland are also significant sources, supplying premium-grade thrown silk to the US luxury textile and weaving industries. The single US tariff line (5004000000) covers all deniers and twist levels of this yarn type, so denier, twist direction (S or Z), and number of plies are commercial specification points rather than classification variables.

HTS 500400 covers yarn produced by throwing (twisting and plying) continuous filaments reeled directly from intact silkworm cocoons. HTS 500500 covers yarn produced by a spinning process from short-staple silk waste fibers. The raw material input — continuous filament vs. short staple waste — is the defining distinction, and suppliers should specify the fiber source on commercial invoices.
Yes. Yarn 'not put up for retail sale' must be in bulk industrial form — typically on cones, bobbins, or in hanks without consumer-facing labeling or packaging. If the same yarn is packaged in small quantities with retail labels for end-consumer sale, it would fall outside HTS 500400 and require reclassification. CBP may examine packaging and labeling at entry to verify the retail-sale condition.
