Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rovings rather than twisted yarn
Glass fiber rovings for packing classify under roving provisions rather than finished yarn.
If when imported as pump repair kits
Glass packing included in pump parts kits classifies with the machinery rather than separately.
If for non-mechanical industrial uses
Yarns not specifically for packing/lubricating functions classify under general industrial yarn provisions.
