Last updated: September 2026 dataPanel and tubular steel radiators — the flat, welded-steel type common in European-style hydronic systems — fall here rather than under the cast iron subheading, with all trade consolidated into 7322190000. Taiwan leads US supply, followed by India and Poland, a supplier profile that reflects strong European manufacturing heritage alongside growing Asian capacity. Because these radiators are often imported as finished building-products components, importers should confirm that the iron or steel substrate is not cast iron; misclassification between 732211 and 732219 is a recurring audit issue.

Welded steel panel radiators require different manufacturing infrastructure — primarily sheet-metal stamping and welding — than cast iron sectional radiators. Taiwan, India, and Poland have well-established sheet-metal fabrication industries suited to panel radiator production, whereas cast iron foundry capacity is more concentrated in different regions.
No. Expansion vessels and thermostatic valve bodies are generally classified under their own headings (e.g., Chapter 84 for pressurized vessels or Chapter 84/85 for valves), not under 732219, which is limited to the radiator units themselves and their direct parts. A licensed customs broker should review the specific component before filing.
