U.S. exports of carbonaceous pastes for electrodes and furnace lining pastes (HS 380130) totaled $2.6M in July 2026.
Importers of Carbonaceous Pastes for Electrodes and Furnace Lining Pastes paid $227K in duties in July 2026 — an effective duty rate of 14% on $1.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Carbonaceous Pastes for Electrodes and Furnace Lining Pastes imports of $1.6M in July 2026 ran 30% above the year-to-date monthly average of $1.3M.
Last updated: July 2026 dataElectrode pastes and furnace lining pastes made from carbonaceous materials are essential consumables in electric arc furnaces, aluminum smelters, and ferroalloy production, where they form self-baking Søderberg electrodes or protective hearth linings. Norway is the leading US supplier under this heading, a direct reflection of that country's dominant position in aluminum and ferrosilicon smelting technology and the associated paste manufacturing expertise. Germany and Brazil also rank among top suppliers, serving different segments of the metallurgical industry. All imports enter under a single 10-digit line (3801300000), so classification disputes typically center on whether a carbon-based product constitutes a paste versus a formed electrode or refractory article classified elsewhere.

Norway has a long-established aluminum and ferroalloy smelting industry that developed deep expertise in Søderberg electrode technology, which relies on continuously fed carbonaceous paste. Norwegian producers have built integrated supply chains for electrode paste that serve global smelter operators, making Norway a natural leading exporter to the US market.
Carbonaceous paste under 3801.30 is an unformed or semi-formed mixture intended to be shaped and baked in situ during furnace operation. Pre-formed, fully baked carbon or graphite electrodes — ready for direct installation — are classified under heading 8545 as electrical carbon products. The key distinction is whether the product arrives as a paste or as a finished electrode article.
