Import Tips
• Verify DOT marking (e.g
• DOT 3A) and hydrostatic test dates on each cylinder before export
• Obtain manufacturer's certification of compliance with 49 CFR 178.36-178.68; retain for CBP review
• Avoid overwrapping to stay under this subheading; common pitfall is misclassifying wrapped cylinders
