Paraldehyde USP Grade Acetaldehyde Trimer
Paraldehyde is the cyclic trimer of acetaldehyde, but pure monomeric acetaldehyde sources are classified under HTS 2912.12.00.00 as acyclic aldehydes without other oxygen functions. This USP grade is used in pharmaceutical formulations as a sedative-hypnotic.

Import Tips & Compliance
• Provide FDA Drug Master File if for pharmaceutical end-use to streamline CBP review
• Confirm monomeric content via GC-MS analysis to avoid misclassification as cyclic polymer under later headings
• Declare as hazardous (UN 2606) with proper ventilation requirements for import manifests
