Last updated: April 2026 dataCast iron central heating radiators occupy a niche in hydronic heating systems where thermal mass and longevity are prioritized over lightweight modern alternatives. The entire heading consolidates into a single 10-digit line, 7322110000, simplifying entry filing but placing all classification weight on confirming the cast iron material specification. China leads US imports under this heading, with the United Kingdom and South Korea also among the top suppliers — a notably diverse geographic mix that reflects both legacy European manufacturing and Asian production capacity. Section 232 tariff exposure applies to steel and iron articles from certain origins, so importers should verify current applicability at the time of entry.

The material specification is the sole distinguishing criterion: 732211 covers radiators and their parts made of cast iron, while 732219 covers radiators of iron or steel that are not cast iron (e.g., stamped or welded steel panel radiators). Importers should obtain mill certificates or material test reports from the manufacturer to confirm the alloy type before classification.
Parts of cast iron central heating radiators are explicitly included within 732211 (HTS 7322110000), so individual sections, headers, and fittings that are identifiable as parts of these radiators should classify here rather than as general cast iron articles elsewhere in Chapter 73.
