Diisobutyl Phthalate (DIBP)
DIBP functions as a fast-fusing plasticizer for PVC coatings and inks, derived from orthophthalic acid. Classified in HTS 2917.34.0150 as other orthophthalic esters under Chapter 29 for pure organic compounds. Alternative to DBP in some applications.

Import Tips & Compliance
• Confirm branched isobutyl structure via NMR to distinguish from n-butyl DBP
• Prop 65 labeling required in California for phthalate exposure
• Avoid packaging that implies consumer use; industrial bulk keeps Chapter 29
