Products classified under HTS 7019.12.00.40
E-Glass Roving for Industrial Packing
E-glass roving consists of continuous glass filaments twisted into strands, specifically designed for use as packing material in industrial machinery seals and gaskets. It falls under HTS 7019.12.00.40 because it is rovings of glass fibers intended for packing or lubricating applications in industry, meeting the criteria for non-woven glass fiber products used in such roles. This classification distinguishes it from general textile rovings or finished fabrics.
High-Temperature Glass Fiber Roving for Lubrication Seals
This high-temperature resistant glass fiber roving is engineered for use as a lubricating material in high-friction industrial environments like pumps and valves. Classified under HTS 7019.12.00.40 as rovings specifically for industrial packing or lubricating, it provides thermal stability and low friction without becoming a finished article. Its unprocessed roving form before annealing keeps it in this heading per Chapter notes.
S-Glass Roving for Valve Stem Packing
S-glass roving, known for superior strength, is used as compressible packing around valve stems in chemical processing plants to prevent leaks. It qualifies for HTS 7019.12.00.40 due to its role as an industrial packing material in the form of rovings, not yet worked into final articles per heading 7006 note. The fused silica content aligns with the broad 'glass' definition in the tariff schedule.
Texturized Glass Roving for Bearing Lubrication
Texturized glass roving features bulked filaments for enhanced lubrication retention in industrial bearings and bushings. Under HTS 7019.12.00.40, it remains classified as rovings for packing/lubricating despite texturing, as pre-annealing processes don't constitute 'worked' per Chapter note (a). Ideal for high-wear applications without metal coatings.
Continuous Filament Roving for Pump Packing
Continuous filament glass roving serves as primary packing in industrial pumps, offering compression and chemical resistance. HTS 7019.12.00.40 covers this as rovings explicitly for industrial packing, retaining heading 7019 character per note even if article-like. Cutting to shape doesn't affect classification per note (b).
Alkali-Free Glass Roving for Lubricant Carriers
Alkali-free glass roving acts as a carrier for dry lubricants in industrial gearboxes, preventing contamination. It fits HTS 7019.12.00.40 precisely as rovings for lubricating materials, with silica content qualifying as glass wool per Chapter note if applicable. Non-reflecting surface ensures transparency in application.
Braided-Ready Glass Roving for Gland Packing
Pre-twisted glass roving optimized for braiding into gland packing for rotating shafts in compressors. Classified in HTS 7019.12.00.40 as industrial packing rovings, prior to any weaving or set assembly. Maintains fiber identity without absorbent layers.
Silica-Rich Roving for High-Friction Lubrication
Rovings with high SiO2 content for extreme lubrication in mining equipment, qualifying as glass wool per Chapter note (a). HTS 7019.12.00.40 applies to their industrial lubricating use as rovings, not falling to 6806. Fused quartz variant included in 'glass' definition.
