Import Tips
• Use inert atmosphere packaging to prevent oxidation; oxidized powder may be questioned as oxide compound
• Comply with TSCA import requirements by pre-registering tellurium as a chemical substance
• Avoid declaring as 'metal powder' – specify 'nonmetal elemental tellurium' to match HTS description
