Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If textured and put up for retail sale
Textured glass yarns for retail packaging fall under specific yarn subheading rather than other glass fiber articles
If in woven fabric form
Woven glass fiber fabrics are classified separately in 7019.40 regardless of end use
If silica content below 60% without required oxide levels
Glass wool not meeting Chapter 70 specifications for heading 7019 falls into mineral wools of heading 6806

Import Tips & Compliance
• Obtain supplier certificate verifying E-glass composition (52-60% SiO2)
• Ensure proper documentation for composite manufacturing end-use
• Watch for reclassification if wound on bobbins as yarn
