Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by carboxamide function ignoring vitamin use
Incorrect functional group emphasis; Chapter 29 prioritizes vitamin-specific headings over general nitrogen functions.
If as laboratory diagnostic reagents
Specific lab use shifts to Chapter 38; pure vitamin identity keeps it in Chapter 29.

Import Tips & Compliance
• Crystalline purity >98% needs HPLC certificate; impurities affect Chapter 29 eligibility
• Declare exact chemical name on commercial invoice to match HTS description precisely
• Monitor for stabilizer additions; excess may invoke note (f) but still stays in 2936.21 if primary vitamin use
