Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as saturated acyclic alcohol peroxide rather than ether
Peroxides take precedence over ethers; classification follows last numerical heading per Chapter 29.
If imported as diagnostic reagent composite with diagnostic indicators
Laboratory reagents containing multiple organic compounds classified as biochemical composites.
If contains nitrogen heterocyclic impurities >1%
Mixtures with nitrogen heterocycles classified under heading 2939 occurring later in chapter.

Import Tips & Compliance
ā¢ Include GC-MS purity certificate; water content <0.01% distinguishes from technical grades
ā¢ Use brown glass or metal containers to prevent peroxide formation during transport
ā¢ Declare as 'not for anesthetic use' if intended for industrial/lab to avoid medical device scrutiny
