Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If filaments are textured or bulked
Textured fiberglass yarns for different reinforcement properties classify separately.
If when used in non-glass-reinforced rubber only
Articles of mineral materials without qualifying glass content shift to Chapter 68.
If imported as rovings rather than twisted cord
Unplied fiberglass rovings classify under 7019.10 regardless of diameter or treatment.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Request supplier affidavits confirming filament diameter tolerance (±0.5 micron) to prevent classification disputes
• Segregate RFL-treated from silane-treated cords, as surface treatments affect adhesion chemistry and potential reclassification
