Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically modified nylon
Modified polyamides classify in 'Other' under subheading note (a)(3), separate from base polymers.
If under 38.1x45.7cm for certain rates
US note limits free rates in 3921, but small articles may residual to 3926.90.
If integral to valve assemblies
Tubes as parts of valves/appliances classify under Chapter 84 heading 8481.
