Products classified under Tariff item 2902.70.00
Cumene (Isopropylbenzene)
Cumene, also known as isopropylbenzene (C6H5CH(CH3)2), is a colorless liquid cyclic hydrocarbon. It is a separate chemically defined organic compound, which qualifies it for classification under Chapter 29, and is used primarily as an intermediate in the production of phenol and acetone.
Cumene UN 1918 Drums
Cumene packaged in 55-gallon UN-approved steel drums (UN 1918) for safe transport. The packaging does not change the chemical identity of the product, which remains a separate chemically defined organic compound, so it is classified under this tariff item.
High Purity Cumene for Acetone Production
Ultra-high purity cumene (>99.9%) specifically distilled for acetone co-production via the cumene peroxidation process. It is a separate chemically defined organic compound, meeting the criteria for classification under this tariff item.
Industrial Grade Cumene 99.5% Pure
Industrial grade cumene with a minimum purity of 99.5% isopropylbenzene, supplied in bulk for petrochemical synthesis, particularly the Hock process for phenol production. It is a separate chemically defined organic compound, qualifying for this tariff item.
Phenol Process Cumene (Technical Grade)
Technical grade cumene optimized for air oxidation in phenol manufacturing, containing trace ethylbenzene impurities but primarily isopropylbenzene. Despite impurities, it is a separate chemically defined organic compound, as Chapter 29 allows for the presence of impurities.
