Certain carbon and graphite electrode products have been subject to antidumping and countervailing duty orders from specific countries. Importers should check the US International Trade Commission and Commerce Department's active order lists before sourcing, as the scope of these orders can be product-specific (e.g., large-diameter graphite electrodes used in electric arc furnaces may be covered while smaller grades are not).

Electrographite articles — manufactured by graphitizing carbon — and amorphous carbon articles may fall under different HTS subheadings even though both appear within the SITC 77886 grouping. The processing method and resulting crystalline structure are the key differentiators, and misclassification between these grades can result in incorrect duty assessment. A licensed customs broker familiar with electrical carbon products can help confirm the correct tariff line.
