AR-Glass Roving for Concrete Reinforcement from Japan
Alkali-resistant (AR) glass roving withstands cement's high pH environment, used in glass fiber reinforced concrete (GFRC) panels. HTS 7019.12.0080 covers this as other rovings meeting fused glass fiber definitions. Zirconia content provides essential chemical durability.

Import Tips
• Certify zirconia content (>14%) to prove alkali resistance qualifying as AR-glass under industry standards
• Provide end-use statements for construction applications to avoid classification as textile reinforcement
• Ensure roving remains untwisted; twisting may shift to yarn subheadings
