sec-Butyl Chloride
sec-Butyl chloride (2-chlorobutane) is a saturated chlorinated derivative of acyclic hydrocarbons, specifically a secondary alkyl chloride with the formula CH3-CHCl-CH2-CH3. It falls under HTS 2903.19.30.00 as it matches the exact subheading for this chemically defined compound. Primarily used as a solvent and intermediate in organic synthesis.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing impurities exceeding chapter note tolerances
Chapter notes limit heading to chemically defined compounds; impure mixtures fall under 'other' saturated chlorinated derivatives.
If when supplied as solution in non-exempt solvent for safety/transport
Chapter note (e) excludes solutions unless solvent use is solely for safety/transport without creating specific use suitability.
If fluorinated (e.g., sec-butyl chlorofluoride derivative)
Fluorinated derivatives classified under separate subheading 2903.30 for chlorinated fluorohydrocarbons.

Import Tips & Compliance
• Provide detailed chemical analysis (NMR, GC-MS) confirming sec-butyl chloride purity and isomer identity to avoid misclassification as n-butyl chloride
• Include Safety Data Sheet (SDS) and UN shipping papers for proper hazmat declaration as Class 3 flammable liquid
• Verify container compatibility with chlorinated solvents to prevent degradation during transport
