Crotonyl Chloride
Crotonyl chloride (2-butenoyl chloride) is an unsaturated acid chloride with a double bond and chlorine, but it is classified as a halide of a carboxylic acid. Per Chapter 29 Note 5(E), halides of carboxylic acids are classified with the corresponding acids, so it falls under heading 29.16, not 2903.

Import Tips & Compliance
• Verify the chemical structure: crotonyl chloride is an acid chloride, not a simple chlorinated hydrocarbon, so it may be classified under heading 29.16
• Provide the product's CAS number and technical data sheet to CBSA for accurate classification
• If uncertain, request a binding tariff classification ruling
