Silica-Rich Roving for High-Friction Lubrication
Rovings with high SiO2 content are designed for extreme lubrication in mining equipment, qualifying as glass wool per Chapter note 4(a). They are continuous untwisted glass fibre bundles, meeting the definition of rovings. Their high silica content does not change their classification as glass fibre rovings.

Alkali-Free Glass Roving for Lubricant Carriers
Alkali-free glass roving acts as a carrier for dry lubricants in industrial gearboxes, preventing contamination. It is a continuous untwisted glass fibre bundle, qualifying as a roving. Its use as a lubricant carrier does not change its classification as a glass fibre roving.
AR-Glass Roving for Concrete Reinforcement
Alkali-resistant (AR) glass rovings are continuous bundles of glass filaments treated to withstand the high alkaline environment of cement and concrete. They are used to reinforce concrete panels, shotcrete, and GRC (glass-reinforced concrete) applications. As untwisted continuous fiber assemblies, they are classified as rovings under this tariff item.
Braided-Ready Glass Roving for Gland Packing
Pre-twisted glass roving optimized for braiding into gland packing for rotating shafts in compressors. It is a continuous glass fibre bundle with a slight twist, still meeting the definition of a roving. Its intended use in industrial packing does not alter its classification as a roving.
C-Glass Roving for Chemical-Resistant Laminates
C-glass rovings are continuous glass fibre bundles with enhanced corrosion resistance, making them suitable for laminates in chemical processing equipment like pipes and tanks. They are untwisted and lightly bound, meeting the definition of rovings. Their chemical-resistant properties do not alter their classification as glass fibre rovings.
C-Glass Roving for Chemical Tank Linings
Corrosion-resistant C-glass roving is used for resin infusion in chemical storage tanks and piping. It is a continuous untwisted glass fibre bundle, qualifying as a roving. Its borosilicate composition provides enhanced corrosion resistance without affecting its classification.
Continuous Filament Roving for Pump Packing
Continuous filament glass roving serves as primary packing in industrial pumps, offering compression and chemical resistance. It is an untwisted continuous glass fibre bundle, qualifying as a roving. Its use as packing material does not change its classification as a glass fibre roving.
