Monochloroacetic Acid (MCA)
Monochloroacetic acid is a colorless crystalline solid used primarily as a chemical intermediate in the production of carboxymethyl cellulose (CMC) and agrochemicals. It falls under HTS 2915.40.1000 as a saturated acyclic monocarboxylic acid that is halogenated with chlorine. This classification applies to the pure chemical compound meeting the chapter's definition for separate chemically defined organic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as a saturated aqueous solution for transport
Solutions in water qualify under chapter note (d) but may shift if concentration exceeds typical limits or renders suitable for specific use.
If impure mixture with >5% stabilizers or anti-dusting agents
Chapter notes exclude mixtures not meeting 'separate chemically defined' criteria; classified as chemical preparations if additives alter general use suitability.
If di- or trichloroacetic acid variant
Heading distinguishes mono- from di-/trichloroacetic acids; molecular chlorine count determines subheading within 2915.40.

Import Tips & Compliance
• Classify based on purity (>98% typical for industrial MCA) to avoid mixtures heading; provide Safety Data Sheets (SDS) and confirm CAS 79-11-8 documentation
• Common pitfall: mislabeling as acetic acid derivative leading to incorrect Chapter 29 placement
