Import Tips & Compliance
• Submit manufacturer's declaration affirming >50% aromatic content per subheading requirements
• Comply with TSCA import certification for chemical substances entering US commerce
• Avoid misdeclaration as general coal tar oil (2707.99.80) by specifying picoline identity

2-Picoline (Alpha-Picoline)
2-Picoline is a colorless liquid heterocyclic compound with the formula C5H4NCH3, derived from the distillation of high temperature coal tar where aromatic constituents predominate. It falls under HTS 2707.99.20.00 as a specific picoline product meeting the chapter's criteria for coal tar distillates. Primarily used as an intermediate in pharmaceutical and agrochemical synthesis.
3-Picoline (Beta-Picoline)
3-Picoline, or beta-picoline, is a methylpyridine isomer obtained from coal tar distillation with aromatic components outweighing non-aromatic ones. Classified under HTS 2707.99.20.00 due to its status as a picoline from high temperature coal tar processing. Key raw material for herbicides and pharmaceuticals.
Picoline Mixture (Mixed Isomers)
Commercial picoline mixture containing 2-, 3-, and 4-picoline isomers from coal tar rectification where aromatics exceed non-aromatics by weight. Falls under HTS 2707.99.20.00 as explicitly named 'picolines' in the tariff. Used in fine chemical manufacturing.
Technical Grade 2-Methylpyridine (Picoline)
Technical grade 2-methylpyridine, known as 2-picoline, sourced from high temperature coal tar with dominant aromatic profile. HTS 2707.99.20.00 applies to this unrefined distillate form used industrially. Essential for synthesis of antiviral drugs and pesticides.
