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 combined with glass for corrosion resistance
Specialty PP often glass-filled, becoming 'combined materials'.
If with socket fusion fittings
Plumbing PP tubes ship with joints, reclassifying.
If reservoirs or tanks from same material
Larger hollow shapes classify as plastic reservoirs.
