  • India splits subheading 2916 20 into 3 lines: 2916 20 10 (Cyclanic, cyclenic or cycloterpenic monocarboxylic acids their anhydrides, halid); 2916 20 20 (Cyclanic, cyclenic or cycloterpenic monocarboxylic acids their anhydrides, halid); 2916 20 90 (Cyclanic, cyclenic or cycloterpenic monocarboxylic acids their anhydrides, halid).
  • Basic customs duty 7.5% on every one of them; with social welfare surcharge and IGST 18% that makes about 27.73%.
  • Lines that name a chemical are for that chemical; one that no line names goes under "Other" (2916 20 90).
