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
