U.S. imports of Abrasives on Woven Textile Base (SITC 66321) totaled $12.3M in August 2026, imported from 36 countries.
Importers of Abrasives on Woven Textile Base paid $1.0M in duties in August 2026, an average duty rate of 8.47% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Abrasives on Woven Textile Base imports of $12.3M in August 2026 ran 11% above the year-to-date monthly average of $11.1M.
Last updated: August 2026 dataCoated abrasive products backed by woven fabric — including abrasive cloth, belts, and discs — serve heavy-duty grinding, sanding, and finishing applications in metalworking, woodworking, and automotive refinishing. The woven substrate provides tensile strength and flexibility that paper or film backings cannot match, making these products the preferred choice for aggressive stock removal and contoured surface work. Imports compete on grit type (aluminum oxide, silicon carbide, zirconia alumina), backing weight, and bond system, all of which affect classification and end-use suitability.

The backing material is the primary classification criterion within SITC 663. Woven textile-backed abrasives fall under 66321, while paper/paperboard-backed products fall under 66322 and other substrates under 66329. Importers should confirm the precise backing construction — woven versus nonwoven versus vulcanized fiber — before declaring the SITC or HTS heading, as misclassification can affect duty treatment.
Common abrasive grains include aluminum oxide (for general metalworking), zirconia alumina (for heavy stock removal on steel), and silicon carbide (for non-ferrous metals and composites). The grain type, grit size, and bond resin are key specification points that buyers and customs brokers should document for both classification and end-use verification purposes.
