Import Tips

• Verify purity of barium sulfate content (>90%) via lab analysis to confirm classification as natural barytes and avoid reclassification as synthetic barium sulfate under 2833

• Include grinding specifications and particle size distribution (e.g

• D50 <10 microns) in commercial invoice to distinguish from crude barytes (2511.10.50)

• Obtain supplier certifications for natural origin to prevent issues with Chapter exclusions for chemically processed materials
