Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If actually dodecanol (C12) due to manufacturing error or mislabeling
Chain length determines specific subheading; C12 alcohols in 2905.22, not C8 isomers
If supplied as aqueous solution (>10% water) for safety transport
Aqueous dilutions excluded from pure compounds per Chapter 29 note (d) unless standard form

Import Tips & Compliance
• Require NMR spectrum verification of branched C8 structure to prevent misclassification as different chain length
• Store below 25°C; provide vapor pressure data (<0.1 mmHg) for VOC compliance declarations
• Avoid pitfall of C7/C9 mixture classification (2905.15/2905.22); assay must show >95% single isomer

2-Ethylhexanol
2-Ethylhexanol is a branched-chain octanol isomer, a colorless liquid used primarily as a chemical intermediate in the production of plasticizers like dioctyl phthalate and as a solvent. It falls under HTS 2905.16.0050 as an isomer of octanol (octyl alcohol), specifically a saturated monohydric acyclic alcohol meeting Chapter 29's criteria for separate chemically defined organic compounds.
4-Methyl-2-pentanol (MIBC)
Note: Correcting—4-Methyl-2-pentanol is C6H14O (hexanol), but for octanol isomers, using 2-methyl-1-heptanol instead for accuracy: 2-Methyl-1-heptanol is genuine C8 isomer used in surfactants. Classified as 'other' octanol isomer, saturated monohydric alcohol.
1-Octanol
1-Octanol, also known as octyl alcohol, is a straight-chain primary alcohol with eight carbon atoms, used in perfume manufacturing, as a flavoring agent, and as a chemical intermediate. It qualifies for HTS 2905.16.0050 as the reference saturated monohydric acyclic alcohol 'octanol' explicitly named in the heading, distinct from isomers.
2-Octanol
2-Octanol is a secondary alcohol isomer of octanol, used as a frother in mineral flotation processes and as a synthetic intermediate. Classified under HTS 2905.16.0050 as an 'other' saturated monohydric acyclic alcohol isomer thereof, fitting Chapter 29's organic compound definitions.
