Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher ethylbenzene content (>20%)
Mixed ethylbenzene/cumene classified as ethylbenzene, which occurs earlier numerically in heading 2902.
If contains polymerization inhibitors
Stabilized cumene with additives >1% becomes mixed chemical preparation, not pure compound.
If lubricating oil base stocks
Cumene in synthetic lubricant formulations classified by end-use as lubricants.

Import Tips & Compliance
• Declare exact impurity profile (ethylbenzene <0.5%) to justify Chapter 29 classification over Chapter 27
• Comply with MARPOL Annex II regulations for bulk liquid chemical shipments via chemical tankers
• Avoid common pitfall of incorrect flash point declaration; cumene requires Class 3 flammable liquid labeling

Cumene (Isopropylbenzene)
Cumene, chemically known as isopropylbenzene (C6H5CH(CH3)2), is a colorless liquid cyclic hydrocarbon used primarily as an intermediate in phenol and acetone production. It falls under HTS 2902.70.00.00 as a separate chemically defined organic compound within the cyclic hydrocarbons subheading of Chapter 29.
Industrial Grade Cumene 99.5% Pure
High-purity industrial cumene (99.5% minimum isopropylbenzene) supplied in bulk for petrochemical synthesis, particularly the Hock process for phenol production. Classified under HTS 2902.70.00.00 as it meets Chapter 29 criteria for separate chemically defined cyclic hydrocarbons.
Cumene UN 1918 Drums
Cumene packaged in 55-gallon UN-approved steel drums (UN 1918) for safe transport, meeting DOT specifications for flammable liquids. Remains classified under HTS 2902.70.00.00 as packaging doesn't alter the chemically defined cyclic hydrocarbon nature per Chapter 29 notes.
High Purity Cumene for Acetone Production
Ultra-high purity cumene (>99.9%) specifically distilled for acetone co-production via cumene peroxidation process. Qualifies under HTS 2902.70.00.00 as a separate chemically defined organic compound without disqualifying additives or impurities.
