AR-Glass Roving for Concrete Reinforcement
Alkali-resistant (AR) glass rovings resist cement's alkaline environment, used to reinforce concrete, GRC panels, and shotcrete applications. HTS 7019.12.00 covers these specialized rovings as continuous glass fiber assemblies.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If textured or bulked for specific composite processes
Textured yarns have modified structure for better resin wet-out, separate from smooth rovings.
If when pre-impregnated with resin as FRP prepreg
Chemical treatment creating prepared binders shifts to Chapter 38 from raw glass fibers.
If imported as multi-axial mats or assembled fabrics
Assembled glass fiber products beyond simple rovings classified as other articles.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Include alkali resistance certification (ZR rating) to justify AR-glass classification over standard types
• Declare end-use in construction composites; bulk packaging affects Form 7501 line descriptions
• Watch for fiber blooming during shipping; proper container ventilation prevents customs holds
