Last updated: April 2026 dataResidual parts of iron or steel central heating boilers — those not elsewhere specified — cover a wide range of replacement and OEM components such as combustion chambers, heat exchanger sections, and mounting brackets that do not fall under more specific parts provisions. The 'not elsewhere specified' qualifier means classification here is appropriate only after confirming the part is not more precisely described under another heading, making a careful classification analysis essential. Section 232 tariff considerations apply given the iron and steel material composition.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
NES indicates that this heading captures boiler parts that are not more specifically described in another tariff provision. Before classifying a part here, importers should confirm it is not covered by a dedicated parts heading for a specific boiler type or component category. A licensed customs broker can assist with this residual classification analysis.
Each part in a mixed shipment should be classified individually based on its own description and function. Parts that are specifically described elsewhere must be classified under those more specific provisions, while only the genuinely residual components fall under the NES heading. Combining all parts under a single heading to simplify entry can result in misclassification and potential penalties.
