Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing oxygen functions from oxidation
Oxidized derivatives (butadiene oxides) shift to Chapter 29 oxygen-function compounds per note structure.
If with antioxidants exceeding safety thresholds
Antioxidant additives beyond Chapter note (g) limits classify as additive preparations, not pure hydrocarbons.

Import Tips & Compliance
• Temperature logs required throughout transit to prove product remained chemically unchanged
• Stainless steel IMO Type 5 tanks mandatory; carbon steel risks polymerization corrosion
• CBP may require inhibitor analysis (<50 ppm if present) to verify transport-only stabilization
