Last updated: April 2026 dataGlass fiber rovings — continuous bundles of parallel filaments wound without twist — serve as a primary feedstock for pultrusion, filament winding, and weaving operations in the composites and industrial sectors. The US schedule divides this heading into two 10-digit lines: 7019120040 for rovings used in industrial packaging and lubricating materials, and 7019120080 for all other glass fiber rovings and articles. Mexico leads US supply, followed by China, whose shipments carry Section 301 exposure; Bahrain and Brazil round out the major source countries.

HTS 7019120040 covers rovings specifically used in industrial applications as packing or lubricating materials, while 7019120080 captures all other glass fiber rovings and related articles not elsewhere specified. The end-use distinction is critical: importers should document the intended industrial application to support the correct line selection.
Rovings originating in China are subject to Section 301 tariffs in addition to standard MFN duties. Given that Mexico is the leading supplier and is not subject to those additional measures under USMCA, origin documentation and tariff engineering decisions are a recurring compliance consideration for buyers.
