Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sulfonated derivative rather than simple thiol
Sulfonated organo-sulfur compounds classified separately per Chapter 29 notes.
If esterified thiol function present
Oxygen-function thiols with ester groups fall under heading 2920 per classification rules.
If imported as a mixture of isomers including excluded forms
Mixtures of organic compounds classified in heading 2942 when not purely defined.

Import Tips & Compliance
• Submit NMR or GC-MS spectra confirming isopropyl substitution to distinguish from excluded analogs
• Package with stabilizer if prone to oxidation; declare as UN2785 for hazardous thiol transport
• Verify not mixed with excluded isomers; pure compounds only qualify for this specific subheading
