Last updated: August 2026 dataLiquid lustres are precious-metal-bearing or metallic-effect preparations applied to fired ceramics or glass to produce iridescent or metallic decorative finishes, classified under tariff line 3207300000. Turkey leads US supply — a reflection of that country's significant decorative ceramics and tile industry — with the Netherlands and United Kingdom also notable sources. Because some formulations contain platinum-group metals or gold compounds, the precious-metal content can substantially affect the declared value and may warrant additional scrutiny during customs valuation review.

The transaction value must reflect the full commercial value of the preparation, including the precious-metal content. Importers should ensure the commercial invoice itemizes the precious-metal concentration or value component, as CBP may scrutinize undervaluation of precious-metal-bearing preparations. A licensed customs broker experienced in specialty chemical imports can advise on proper valuation methodology.
No — heading 320730 covers liquid lustres and similar preparations regardless of whether the intended substrate is ceramic, glass, or porcelain. The classification is driven by the nature of the preparation itself (a metallic or iridescent decorative coating applied by firing), not by the substrate to which it will be applied.
