Last updated: August 2026 dataPortable fan-forced heaters, radiant panel heaters, baseboard units, and electric soil heating cables that do not fit the storage-radiator or instantaneous-water-heater categories all converge in this residual space-heating heading. China and Vietnam together account for the bulk of US imports, and Chinese-origin goods are subject to Section 301 tariffs — a landed-cost factor that has driven sourcing diversification toward Vietnam, Canada, and Thailand. The US schedule breaks out fan-forced portable space heaters (8516290030), other portable space heaters (8516290060), and a catch-all line (8516290090) for fixed space-heating and soil-heating apparatus, making the portable-versus-fixed and fan-forced-versus-radiant distinctions critical for correct 10-digit classification.

Portability is generally evidenced by a self-contained design with a carrying handle, a cord and plug (rather than hardwired installation), and no permanent mounting hardware. Fixed units intended for wall or baseboard installation typically require an electrician and are not designed for relocation. Product manuals, installation instructions, and the manufacturer's product specification sheet are the most useful supporting documents for making this distinction on entry.
Soil heating apparatus — cables or mats embedded in soil or growing media to maintain root-zone temperature — shares the same heading (851629) as space heaters but falls under the catch-all 10-digit line 8516290090. Primary end users include greenhouse operators, agricultural nurseries, and sports turf managers. Because the product is purely industrial or agricultural in application, no special admissibility agency review is triggered at US Customs entry.
