Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If latex-derived synthetic-natural mix
Blends with synthetic latex fall under synthetic rubber primary forms per note 2.
If vulcanized into finished sheets
Vulcanized plates/sheets are hardened rubber under 4007, not primary.
If prevulcanized latex form
Prevulcanized latex permitted in 4001.12 but changes from crumb to liquid primary.
