Import Tips
• Ensure the crystals are properly classified as a telluride salt and not as a doped semiconductor element, which would fall under heading 28.53 or 38.18
• Provide a certificate of analysis to confirm chemical purity and composition when clearing customs
• Verify whether the goods qualify for duty relief under the Chemicals and Plastics Duties Reduction or Removal Order
