Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporating metal fittings or sold as complete hose assemblies
Articles like plastic tubes with attached fittings classify under 3917 per US note, not as separate seals.
If steel-reinforced or metal washers
Predominantly metal articles shift to Chapter 73; plastic content below threshold moves away from 3926.
If for non-sealing plastic spacers in plumbing
Spacers without sealing function are other plastic articles, not specifically gaskets or washers.

Import Tips & Compliance
• Provide NSF/ANSI 61 certification for potable water contact to ensure regulatory compliance
• Declare exact dimensions and pressure ratings; undersized washers risk reclassification as fittings under 3917
• Bundle in sets only if for retail; bulk shipments may trigger different valuation rules
