Lead crystal drinking glasses are classified based on their lead monoxide content and whether they are cut or uncut, which can shift the applicable HTS subheading and duty rate. From an admissibility standpoint, FDA may scrutinize lead-crystal drinkware for potential lead leaching, particularly for items marketed for food and beverage use, so compliance with FDA guidance on lead in food-contact articles is advisable.

The degree of decoration — whether a glass is plain, colored, cut, or engraved — is a classification factor under the HTS. Cut crystal and hand-decorated stemware often fall into different subheadings than plain machine-made tumblers, affecting both duty rates and statistical reporting. Importers should confirm the manufacturing method and decoration details with suppliers before filing entry.
