Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If inkjet printing ink containing >10% thiodiglycol
Finished inks are classified by function in 3215, not by chemical components.
If pre-mixed as chemical additive for inks
Prepared additives for specific uses like printing shift to mixtures in 3824.
If generic thiodiglycol derivatives not exactly matching the named compound
Only specifically named bis(2-hydroxyethyl)sulfide stays in 2930.70; analogs go to residual.

Import Tips & Compliance
• Provide evidence of >90% purity to distinguish from ink preparations in Chapter 32 or 38
• Register under TSCA if not on inventory; submit PMN if modified formulation
• Bulk packaging must show it's not retail-packed to avoid 3212 classification
