Which code does this activity belong in?
Petrochemical Manufacturing (32511) covers establishments making acyclic hydrocarbons like ethylene and propylene or cyclic aromatic hydrocarbons like benzene and toluene from refined petroleum or liquid hydrocarbons. The key distinction from Other Basic Organic Chemical Manufacturing is that petrochemicals must be derived specifically from refined petroleum or liquid hydrocarbons as feedstocks; basic organic chemicals made from other sources or cyclic intermediates produced from natural gas rather than petroleum are classified in Other Basic Organic Chemical Manufacturing instead.
