Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporated into final cosmetic preparation
Mixtures for retail cosmetic use classify under Chapter 33, not pure Chapter 29 compounds.
If as disinfectant goods put up for retail sale
Retail-packaged disinfectants containing MIT shift to Chapter 38 per Chapter 29 exclusion (k).
If classified as nucleic acid salt rather than simple thiazole
Nucleic acids/salts have separate specific subheading earlier in 2934.10.
