Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not silica-specific (other colored)
Non-silica >93% colored fabrics under .90.15; silica purity defines .30.
If impregnated with friction materials
Friction-impregnated glass fabrics for brakes classify in Chapter 68 as friction materials.
If textile glass fiber mats, not woven
Non-woven mats revert to 7019.31, excluding closed woven fabrics.

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
• Document color as functional (e.g
• heat degradation indicator); ensure no metal threading to avoid composite classification; batch-test silica purity
