Import Tips

Conduct stitch density test (at least 10 stitches per cm) if questioned, as low density could misclassify toward other headings

Declare as 'underwear' only if primarily marketed/functionally used as such; outerwear use may trigger reclassification

Include mill test certificates for wool purity to prevent disputes over 'other textile materials' categorization
