Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If certified as pure hydrocarbon gas >99.99%
Research-grade gases meeting Chapter 28 purity may classify as pure elements/compounds.
If when sold as certified reference material
Butane mixtures prepared as lab standards for calibration classify as diagnostic reagents.
If imported filled in gas chromatograph calibration kits
Lab gas in complete calibration equipment imports under instrument classification.

Import Tips & Compliance
• Provide GC-MS analysis certificate proving butane identity and impurity levels
• Declare as UN1978 liquefied petroleum gas; ensure cylinder retest dates current
• Lab gas importers often overlook valve outlet standards (CGA510 vs CGA600)
