HS code for Steel bathtub: 7324.29
Iron (other than cast) or steel, baths.
Classification of steel bathtub under HS 7324.29
HS code 7324.29 applies to baths made of iron or steel, excluding those made of cast iron. This classification falls under Chapter 73, which covers articles of iron or steel. The primary factor for this code is the material (pressed steel or sheet steel) and the intended use as sanitary ware. These products are typically manufactured by stamping a single sheet of steel into the desired shape, which is then coated with a layer of porcelain enamel or other protective finishes to prevent oxidation and provide a hygienic surface. The classification logic follows the transition from raw materials (Chapter 72) to finished articles (Chapter 73). For a product to fall under 7324.29, it must be a finished sanitary article. Most modern steel bathtubs are manufactured from pressed steel sheets which are then coated with vitreous enamel. This distinguishes them from the heavier, molded cast iron tubs. The classification is based on the primary material and the functional design as a plumbing fixture. It is important to note that this code covers the tub itself; associated plumbing fittings like faucets, drains, or showerheads may be classified separately under heading 8481 if they are shipped independently of the bathtub unit.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
