o-Tolyl Isocyanate from Germany
o-Isocyanic acid, o-tolyl ester (o-tolyl isocyanate) is a monoisocyanate with the formula C6H4(CH3)NCO, explicitly covered under HTS 2929.10.20.00 for its isocyanate nitrogen function. It acts as an intermediate in pharmaceutical synthesis and agrochemicals, reacting to form ureas and carbamates. This fits Chapter 29 as a separate chemically defined compound with 'other nitrogen function' per heading 2929.

Import Tips
• Handle as UN 2483 hazardous substance with proper placarding; provide TSCA import certification
• Pitfall: Incorrectly declaring as 'ester' without isocyanate function leads to wrong heading
