Methanol AR (Analytical Reagent)
Analytical reagent grade methanol with >99.8% purity for laboratory use in chromatography and spectroscopy. Falls under HTS 2905.11.20 as 'other' methanol, a chemically defined saturated monohydric alcohol per chapter 29 note 1(a). Distinguished from USP/pharmaceutical grades by intended laboratory rather than medicinal application.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If USP/pharmaceutical grade
Higher purity medicinal methanol classified in the specific USP subheading before 'other' category.
If diagnostic reagent preparation
Lab reagents put up for diagnostic use excluded from chapter 29 per note 2(e), moving to prepared diagnostic reagents.
If contains cyclic alcohol impurities
Presence of cyclic alcohols changes classification from acyclic alcohols (2905) to unsaturated/cyclic alcohols (2906).

Import Tips & Compliance
• Include ACS/AR specification certificate; lab-grade methanol requires proof of analytical purity for correct classification
• Label containers with 'For Laboratory Use Only' to prevent reclassification as general industrial chemical
• Verify stabilizer content <0.1%; added stabilizers must meet chapter note 1(f) for preservation only, not specific use
Related Products under HTS 2905.11.20
Industrial Grade Methanol
High-purity methanol (CH3OH) used as a solvent in chemical manufacturing and as a feedstock for formaldehyde production. Classified under HTS 2905.11.20 as a saturated monohydric acyclic alcohol, specifically 'other' methanol not covered by higher purity pharmaceutical grades. Meets chapter 29 requirements for separate chemically defined organic compounds.
Methanol with 0.1% Stabilizer
Methanol containing 0.1% polymerization inhibitor stabilizer for safe transport in chemical processing. Properly classified HTS 2905.11.20 per chapter note 1(f) as stabilizer-added acyclic alcohol necessary for preservation, not rendering it suitable for specific use.
Pharma-Grade Methanol Precursor
High-purity methanol used as reaction solvent/intermediate in pharmaceutical API synthesis. HTS 2905.11.20 as 'other' methanol; chemically defined organic compound per chapter notes, distinguished from USP grade by manufacturing rather than final medicinal use.
Methanol for Biodiesel Production
Technical methanol specifically for transesterification in biodiesel manufacturing from vegetable oils. Classified HTS 2905.11.20 as pure saturated monohydric alcohol; meets chapter 29 purity standards despite dedicated end-use.
Electronic-Grade Methanol
