Uncolored Glass Fiber Battery Separator Mat
A chemically bonded, closed-structure non-woven fabric from colorless glass fibers used as separators in lead-acid batteries to prevent short circuits. Classified under HTS 7019.72.40.60 as other non-colored closed chemically bonded glass fiber fabrics. The closed pore structure is achieved via chemical binders, distinguishing it from papers or tissues.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If colored
Colored chemically bonded closed fabrics have a separate subheading in 7019.72.
If in sheet or roll form resembling paper
Glass fiber sheets or profiles not specifically fabrics may fall under 7010 if not qualifying as bonded mat.
If impregnated with plastics for industrial use
Textile fabrics coated or laminated with plastics for technical uses shift to Chapter 59.

Import Tips & Compliance
• Include technical specs showing closed fabric structure and chemical binder use; battery manufacturers often require certifications
• Avoid classifying as battery parts under 8507 if imported separately
• Pitfall: confusing with cellulose-based separators under paper headings
