Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in the form of salts rather than the chloride
Heading 2904.10 covers sulfo groups, their salts, and ethyl esters; chlorides specifically enumerated first.
If put up specifically as synthetic coloring intermediate beyond Chapter 29 scope
Chapter excludes coloring matter of heading 3204; remains in 2904 if chemical compound.
If classified as other organic compounds in heading 2942
Goods classifiable in multiple headings go to the last numerical order; 2942 follows 2904.

Import Tips & Compliance
• Require ACS certificate of analysis; ensure inhibitor-stabilized if required for stability
• Declare exact purity (>99%) to avoid scrutiny as impure mixture under Chapter notes
• Check for anti-dusting agents; additions must not render suitable for specific use (note g)
