Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If explicitly described as fenproporex salt rather than methadone intermediate
Fenproporex salts have a distinct subheading; tariff headings prioritize specific naming over general intermediate use.
If for industrial use as a saturated acyclic ketone derivative intermediate
If emphasizing oxygen-function (ketone group in synthesis pathway), it may fall under heading 2915 per Chapter Note 4 on oxygen functions, but nitrile takes precedence.
If imported as a mixture with solvents for transport exceeding safety-only criteria
Solutions in solvents not solely for safety/transport reclassify to mixtures of Chapter 38 per Chapter Note 1(e).

Import Tips & Compliance
• Include salt formation details and pH stability data in import documentation to confirm classification as the named base equivalent
• Monitor for anti-caking agents; if added beyond stabilization needs, it may trigger reclassification per Chapter Note 1(f)
