Import Tips

• Verify chemical purity and activator content via lab analysis to confirm luminophore function and avoid reclassification as general inorganic chemicals under Chapter 28

• Provide Safety Data Sheets (SDS) and emission spectra documentation to customs for proof of use as luminophores

• Avoid common pitfalls like mislabeling as 'pigment' without specifying phosphor properties, which could shift to heading 3206 other subheadings
