Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mixed with stabilizers beyond preservation needs
Additives making it suitable for specific use exclude it from Chapter 29 per notes 2(g) and 2(e).
If sulfur impurity present
Organo-sulfur contaminants link it to heading 2930 organo-sulfur compounds.
If for bulk industrial solvent blends
If diluted beyond Chapter 29 allowances, classifies as halogenated/sulfonated derivatives in earlier headings.
