U.S. imports of electric storage heating radiators (HS 851621) totaled $5.9M in August 2026, imported from 12 countries.
Importers of Electric Storage Heating Radiators paid $2.1M in duties in August 2026, an effective tariff rate of 36.47% of the $5.9M imported — duty actually collected as a share of that value, not the published tariff schedule. Electric Storage Heating Radiators imports of $5.9M in August 2026 ran 265% above the year-to-date monthly average of $1.6M.
Last updated: August 2026 dataElectric storage heating radiators — which absorb off-peak electricity in a heat-retaining core and release warmth gradually — occupy a single 10-digit line (8516210000) with no further US schedule subdivision. China and Vietnam are the dominant suppliers to the US market, with Mexico also contributing. These units are common in markets with time-of-use electricity pricing and are distinct from simple panel heaters or fan-forced convectors, a specification difference that matters for both classification and energy-efficiency compliance. Chinese-origin radiators are subject to Section 301 tariffs, and importers should verify that products meet applicable UL electrical safety standards before entry.

A storage heating radiator contains a high-density heat-retaining core (typically ceramic bricks or similar material) that charges during off-peak hours and releases heat over an extended period. An ordinary panel or convector heater converts electricity to heat immediately without storage capacity. This functional distinction determines whether a unit classifies under 851621 (storage radiators) or the broader 851629 (other space heating apparatus), so technical specifications confirming the storage mechanism are essential documentation.
Section 301 tariffs apply to Chinese-origin electric storage radiators. Importers should check the US International Trade Commission and Commerce Department databases for any active antidumping or countervailing duty orders covering this product category from specific origins, as trade remedy coverage can change. A licensed customs broker can assist with an AD/CVD scope review before importation.
