Dibutyl Phthalate (DBP)
Dibutyl phthalate is an ester of orthophthalic acid used primarily as a plasticizer in PVC production for flexible plastics like flooring and cables. It falls under HTS 2917.34.0150 as an 'other' aromatic polycarboxylic acid ester, specifically the dibutyl ester derivative of phthalic acid. This classification applies to its pure chemical form for industrial use.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other plasticizers or solvents exceeding 50% concentration
Blends become chemical preparations of Chapter 38 rather than pure esters of Chapter 29.
If dissolved in organic solvents for safe transport
Chapter 29 note (e) excludes solvent solutions unless solely for safety/transport without specific use adaptation.
If classified as ester of other aromatic polycarboxylic acids like terephthalic
Specific isomer structure determines subheading; orthophthalic (1,2-) vs other positions changes classification.

Import Tips & Compliance
• Provide Safety Data Sheets (SDS) and purity certificates to verify chemical composition meets Chapter 29 definitions for separate organic compounds
• Ensure REACH compliance for EU imports and TSCA registration for US; phthalates face restrictions in consumer goods
• Avoid misclassification as mixtures; test for impurities exceeding trace levels which could shift to Chapter 38
