Import Tips

Include lab analysis showing particle size and purity to distinguish from synthetic abrasives in Chapter 28

Label clearly as 'natural pumice powder' to prevent misclassification as prepared pigments or colors

Check for heat-treatment declarations; excessive processing may require heading 6805 classification
