1702.11.00.00 - Containing by weight 99 percent or more lactose, expressed as anhydrous lactose, calculated on the dry matter

This HTS category specifically covers lactose and lactose syrup that contains 99 percent or more lactose by weight, calculated on a dry matter basis and expressed as anhydrous lactose. This high purity requirement distinguishes these products from other lactose and lactose syrup preparations. Examples within this classification include pharmaceutical-grade lactose or highly refined lactose used in specialized food manufacturing processes where precise lactose content is critical.

The primary distinction from its sibling category, 1702.19.00.00, lies in the minimum percentage of lactose. While 1702.11.00.00 demands a purity of 99% or more lactose (anhydrous, dry matter), the "Other" category (1702.19.00.00) encompasses lactose and lactose syrup with lower lactose concentrations or those that do not meet the stringent purity threshold defined for this subheading.

As this subheading is a leaf node, there are no further subcategories. Classification is determined solely by meeting the stipulated purity criteria of 99% or more anhydrous lactose on a dry matter basis. This ensures that only the most refined forms of lactose and lactose syrup are placed within this specific classification.
