Import Tips
• Verify material composition with lab tests to confirm casein content, as misclassification to plastic blanks (3926.90) is common
• Include supplier certificates stating 'button blanks of casein' for CBP review to avoid reclassification
• Import in bulk quantities with commercial packaging to qualify as parts, not retail-ready goods
