Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when put up as herbicide formulation >95% 2,4-D salts
High-concentration herbicide goods containing 2,4-D salts classified as formulated products in 3808 rather than pure chemical.
If classified primarily by the amine component
Misclassification could occur if focusing on methylamine structure rather than the dominant carboxylic acid function per chapter notes.
If for certain ester precursors or related intermediates
Some 2,4-D production intermediates with different oxygen functions may fall under earlier saturated acid headings.

Import Tips & Compliance
• Include EPA Establishment Number and Product Label with import docs; test for amine content to confirm 46-48% 2,4-D acid equivalent
• Avoid common error of shipping without proper corrosive class 8 placarding
• Check state-specific restrictions on 2,4-D amine formulations
