Last updated: August 2026 dataCast iron bathtubs — whether left bare or finished with a vitreous enamel or precious-metal coating — are heavy, durable fixtures that occupy a premium segment of the bath products market. The US tariff schedule separates tubs coated or plated with precious metal (7324211000) from standard cast iron baths, enameled or not (7324215000). China dominates US imports of this heading, with Portugal and Poland serving as notable European sources that supply higher-end enameled product lines.

Tariff line 7324211000 covers cast iron baths coated or plated with precious metal (gold, silver, platinum, etc.), while 7324215000 covers all other cast iron baths, including the common vitreous-enamel-coated variety. The precious-metal distinction affects both classification and valuation, so importers of decorative or luxury fixtures should verify the coating specification with the manufacturer.
European foundries have long-established expertise in high-quality vitreous enameling and freestanding tub design, commanding premium price points that offset higher production costs. Their product mix tends toward architect-specified and luxury-segment baths, where design provenance and finish quality are key purchasing criteria rather than unit price alone.
