Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If latex is prevulcanized
Prevulcanized latex permitted under note but classified separately from standard NBR latex.
If compounded with pigments or plasticizers
Chapter Note 5(a) excludes mixtures with prohibited additives from primary forms, moving to waste/scrap heading.
If heavily modified into adhesive base
Significant chemical modification changes essential character from rubber to prepared adhesive.
