1-Ethoxy-2,3-propanediol
1-Ethoxy-2,3-propanediol is an ether-alcohol-phenol derivative used as a reactive diluent in polyurethane coatings and epoxy resins. Though primarily ether-alcohol, its phenolic substitution qualifies it under the ether-phenol/ether-alcohol-phenol heading 2909. Supplied as viscous liquid with transport stabilizers.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purely ether-alcohol without phenolic substitution
Absence of phenolic ring shifts to earlier ether-alcohol subheadings within 2909.
If when pre-mixed as 50% solution in reactive monomers
Chemical preparations diluted beyond stabilizer allowances classify as mixtures under Chapter 38.
If imported as fully polymerized resin component
Polymerized ether derivatives become amino-resins under Chapter 39 rather than monomers.

Import Tips & Compliance
• Submit structural formula and CAS number (52214-84-5) confirming classification within ether-alcohol-phenol scope
• Verify solvent content <5%; solutions exceeding transport/stabilizer limits per Chapter Note 6(e) reclassify as mixtures
• Avoid bulk packaging without stabilizers; unprotected shipments risk polymerization and customs rejection
