Last updated: July 2026 dataSlide fasteners — commonly known as zippers — are a high-volume apparel and soft-goods trim input with significant Section 301 tariff exposure for shipments of Chinese origin, making supplier diversification a recurring procurement consideration for US importers. Classification at the HTS level turns on the fastener's construction material (metal teeth versus plastic/coil) and whether the fastener is presented by the meter or as finished units, each carrying distinct duty treatment. Zipper specifications — tooth material, tape width, pull type, and chain length — are tightly controlled by apparel and luggage buyers and must be accurately reflected in commercial documentation.

At the HTS level, slide fasteners are subdivided by the material of the interlocking elements: metal-tooth zippers and plastic or synthetic-coil zippers fall under different tariff lines with potentially different duty rates. The tape material is secondary; the tooth or coil material is the primary classification criterion.
Standard commercial documentation — commercial invoice, packing list, and bill of lading — should specify tooth material, tape width, unit length or meterage, and country of origin. For shipments subject to Section 301 measures, a precise country-of-origin declaration is essential, and importers should retain supplier certifications to support any origin claims in the event of a CBP inquiry.
