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
