Dihydroxyacetone Dimer (DHA Dimer) from Germany
DHA Dimer is the cyclic trimer form of 1,3-Dihydroxyacetone, a stable ketone-alcohol used in self-tanning formulations to prevent oxidation during storage. Classified under HTS 2914.40.60.00 as it retains the core ketone-alcohol structure with oxygen functions. It dimerizes in solution but is imported as a white powder for reconversion to active DHA.

Import Tips
• Provide stability data and dimer conversion specs in documentation; label as 'for further manufacturing' to avoid cosmetic mixture classification; watch for humidity control in shipping to prevent premature dimerization
