Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7019Same rate: 39.9%

If pre-impregnated with resin (prepregs)

Roving/prepreg forms with coatings shift out of plain chopped strands.

3824.99Lower: 15% vs 39.9%

If heavily surface-treated for specific resin compatibility beyond basic sizing

Excessive chemical treatment may classify as prepared binder/additive, not pure glass fiber.

Import Tips & Compliance

Provide tensile strength and composition lab reports to distinguish S-glass from standard E-glass during verification

Bundle in fiber-specific invoices separating by type to prevent averaging lengths across shipments

Check for anti-dumping duties on certain glass fiber origins; origin certificates mitigate risks
