Import Tips

• Verify isotopic purity certification from supplier exceeding 99% by volume to meet HTS 2804.29.0030 criteria

• Obtain Material Safety Data Sheets (MSDS) and ensure compliance with DOT regulations for compressed gas transport

• Avoid misclassification as standard helium (2804.29.0010); declare isotopic composition accurately to prevent audits
