HS code for Enamelled cast iron bath: 7324.21
Cast iron, baths, whether or not enamelled.
Classification of enamelled cast iron bath under HS 7324.21
The classification of enamelled cast iron baths falls under HS code 7324.21. This code is specifically designated for sanitary ware and parts thereof made of cast iron, specifically baths, regardless of whether they have been enamelled or not. The primary factor for this classification is the material composition (cast iron) and the intended function (sanitary use). Enamelling is a common finishing process for cast iron baths to provide a smooth, durable, and hygienic surface, but it does not change the fundamental classification under this subheading. The General Interpretative Rules (GIR) dictate that products are classified based on their material of construction and their specific utility within the Chapter 73 framework for iron and steel articles. This code is part of a hierarchical structure where sanitary ware is first identified by material, then by specific item type. Cast iron is distinguished from other forms of iron or steel due to its carbon content and manufacturing process, which involves melting the metal and pouring it into a mold. This results in a heavy, durable product that is distinct from pressed steel alternatives. Furthermore, the term "sanitary ware" in the context of Chapter 73 refers to items designed for personal hygiene or bathroom use. The inclusion of "parts thereof" means that components specifically designed for these baths, such as specialized feet or integrated overflows, are also classified here if presented with the main article. The enamelling process involves fusing a glass-like substance to the metal at high temperatures, which is a standard treatment for cast iron to prevent oxidation and provide a non-porous surface. This treatment is explicitly mentioned in the subheading description, ensuring that both raw and finished cast iron baths are grouped together for tariff purposes. This classification is globally recognized under the WCO Harmonized System, facilitating uniform trade statistics and tariff application across international borders.

Codes often confused with 7324.21
Common mistake. Confusion often arises between 7324.21 and 7324.29. While 7324.21 is strictly for cast iron, 7324.29 covers baths made of other types of iron or steel, such as pressed steel baths. Additionally, plastic or acrylic baths are classified under 3922.10, and ceramic baths fall under 6910.10. It is vital to verify the base metal before assigning the code, as the weight and thickness of cast iron are its primary identifiers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
