p-tert-Octylphenol
p-tert-Octylphenol is a monophenol with an octyl alkyl chain attached to the phenol ring, classified under HTS 2907.13.00.00 as it matches the definition of octylphenol isomers. It is primarily used as an intermediate in producing nonionic surfactants and resins.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing additional functional groups beyond simple alkyl substitution
Other monophenols not specifically listed as octyl/nonylphenol fall under the residual monophenols heading.
If when formulated into nonionic surfactants for retail sale
Mixtures containing octylphenol ethoxylates are classified as surface-active preparations, not pure phenols.
If imported as prepared chemical additive with stabilizers
Chemical preparations not elsewhere specified may apply if additives render it suitable for specific use per Chapter 29 note 1(g).

Import Tips & Compliance
• Provide chemical purity certificates and CAS number (140-66-9) to confirm classification as octylphenol isomer
• Ensure SDS includes handling precautions due to endocrine disruptor status; comply with TSCA registration
• Verify importer has proper EPA notifications for new chemical substances if applicable
