Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If glass wool based
Glass wool variants for insulation differ from continuous filament AR-glass.
If pre-impregnated with resin
Resin-impregnated fibers become prepared binders for construction in Chapter 38.
If assembled into mats or veils
Assembled mats from AR-glass shift to 'other articles' subheading.

Import Tips & Compliance
• Certify alkali resistance (ZrO2 content >14%) via ISO testing to distinguish from standard yarns
• Declare intended end-use as construction composites to avoid textile misclassification
• Ensure dust-free packaging and worker safety data for fine fiber imports
