Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If esterified with carboxylic acid functions
Esters of Chapter 29 oxygen-function compounds classify with the acid-function compound (later heading) per note 5(A).
If containing ester or acid salt derivatives
Organic salts of oxygen-function compounds classify with the organic component per note 5(C)(1).

Import Tips & Compliance
• Use stainless steel drums with nitrogen blanketing; acetals are moisture-sensitive and hydrolyze during transit
• Pre-clear with FDA if ultimate use is pharmaceutical intermediate (even if not final drug)
• Document synthesis route to prove compliance with Chapter 29 purity requirements vs
• Chapter 38 preparations
