Import Tips
• Include batch certificates verifying no added solvents beyond transport safety limits per Chapter Note 2(e)
• Classify based on principal amine-function; ester derivatives follow acid component per Note 5(A) but remain here
• Monitor for sulfonated forms, which may require heading 2904 evaluation if sulfohalogenated derivatives apply
