6212.10.70.00 - Containing 70 percent or more by weight of silk or silk waste

This HTS classification, 6212.10.70.00, specifically covers brassieres that are constructed with 70 percent or more by weight of silk or silk waste. These are items primarily designed to support and shape the breasts, made from the luxurious and natural fibers of silk. The emphasis on silk content is a crucial distinguishing factor for classification within this subcategory.

Distinction from its sibling category, 6212.10.90, is based solely on the material composition. While 6212.10.90 would encompass brassieres made from other materials not meeting the 70% silk threshold, this specific code isolates brassieres predominantly made from silk. This allows for precise tracking and tariff application based on the valuable raw material used in their manufacture.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification under 6212.10.70.00 hinges entirely on meeting the 70% silk or silk waste by weight requirement, in conjunction with the article being identifiable as a brassiere and not knitted or crocheted. Examples would include brassieres made entirely of silk satin, silk charmeuse, or a blend where silk constitutes the overwhelming majority of the weight.
