Last updated: July 2026 dataGlass wool — the fine, randomly oriented fiber product used primarily for thermal and acoustic insulation — enters the US under five tariff lines (7019801000 through 7019809000) that distinguish insulation batts, pipe coverings, and other nonwoven insulation forms from residual glass wool articles. Canada and Mexico dominate supply, reflecting integrated North American building-products supply chains and the logistical advantages of bulk insulation shipments from nearby manufacturing. Imports from both countries may qualify for preferential duty treatment under USMCA, subject to applicable rules of origin.

The US schedule provides distinct 10-digit lines for batts of nonwoven glass fibers (7019801010) and pipe coverings of nonwoven glass fibers (7019801020), both within the broader insulation products grouping (7019801000). The product form — flat batt versus pre-formed pipe section — determines which line applies, and importers should ensure commercial invoices describe the physical form clearly.
Importers should check the US International Trade Commission and Commerce Department databases for any active trade remedy orders covering glass wool or fiberglass insulation products, as this sector has historically been subject to trade remedy proceedings. The applicable order, if any, would be product- and country-specific, so a licensed customs broker or trade attorney should be consulted before entry.
