Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the ZDBC is imported as a pure separate chemically defined compound
Pure dithiocarbamates are organo-sulphur compounds classifiable in Chapter 29.
If the product is a compound plasticizer rather than an accelerator
Compound plasticizers for rubber are classified under a different subheading of heading 3812.
