Import Tips
• Provide chromatograph reports confirming butane purity within 90-94% to support classification
• Comply with EPA import requirements for calibration standards used in emissions testing
• Avoid bulk shipments without proper metering; declare in gaseous state to prevent liquid LPG confusion
