E-Glass Roving for Wind Turbine Blades
E-glass rovings are continuous fiber bundles of glass filaments designed specifically for reinforcing composite materials in wind turbine blades. They fall under HTS 7019.12.00 as rovings, which are untwisted and lightly sized assemblies of glass strands used in filament winding and pultrusion processes.

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 in sliver form rather than continuous roving
Slivers are untwisted collections of discontinuous strands, classified separately before roving stage.
If chopped into short strands
Chopped strands are cut to fixed lengths for compounding, distinct from continuous rovings.
If silica content below 60% without specified alkaline/boric oxides
Chapter notes exclude such mineral wools from glass fibers, placing them in Chapter 68 as other minerals.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Verify the silica content meets Chapter 70 glass definitions; non-compliant mineral wools shift to 6806
• Include technical data sheets proving roving specification (tex size, filament count) for customs verification
• Avoid misclassification as yarn by confirming no twisting; provide sizing type documentation
