7013.33 - Of lead crystal:

This HTS category, 7013.33, specifically covers drinking glasses crafted from lead crystal, intended for table, kitchen, toilet, office, or indoor decorative purposes. Lead crystal is characterized by a significant percentage of lead oxide, which imparts exceptional brilliance, clarity, and a distinctive resonance to the glass. This designation is crucial for distinguishing these high-quality glassware items from those made from other glass materials.

Within the broader classification of "Other drinking glasses, other than of glass-ceramics," this subcategory differentiates itself by the material composition. While its sibling category, 7013.37, encompasses other types of drinking glasses not made of lead crystal, 7013.33 is exclusively for lead crystal varieties. The purpose of this distinction is to accurately account for the material value and potentially different import duties associated with lead crystal articles.

The subcategories under 7013.33 further refine the classification based on the customs value of the individual drinking glasses. These subdivisions (7013.33.10.00, 7013.33.20.00, 7013.33.30.00, and 7013.33.50.00) are essential for determining the applicable ad valorem duty rates, as the value per item significantly impacts the final import cost. This hierarchical structure ensures precise classification for both customs administration and trade data analysis.
