Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure hydrocarbon epoxides without oxygen functions
Simple hydrocarbon epoxides lacking additional functional groups may classify under earlier acyclic hydrocarbons.
If heterocyclic compounds with nitrogen
Presence of nitrogen heteroatoms would shift to Chapter 29 heterocyclic headings per exclusion notes.

Import Tips & Compliance
• Label containers with UN 3025 (Butylene oxide) markings and ensure secondary containment for spill prevention
• Confirm no sulfonation or halogenation occurred during synthesis, as modified derivatives stay with parent per chapter notes
• For bulk imports, arrange bonded warehouse storage to manage duty suspension during processing
