Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported as fungicide/herbicide formulation >5% active
Pesticide preparations containing OIT as active ingredient classify in Chapter 38, not pure compounds.
If organo-sulfur classification emphasized over thiazole ring
Other organo-sulfur compounds could apply but Chapter 29 note prioritizes last numerical heading (2934).
If as part of multi-component biocide mixture
Chemical mixtures not meeting 'chemically defined' criteria shift to Chapter 38 preparations.
