Last updated: July 2026 dataThe most granular residual category within NAICS 327, this grouping captures specialty mineral articles not elsewhere classified — such as manufactured graphite electrodes, carbon and graphite shapes, mica fabrications, and friction materials — that serve niche but technically demanding roles in steel production, electrical equipment, and high-performance braking systems. Trade flows are often concentrated among a small number of technically capable suppliers, and several product lines within this category have faced antidumping scrutiny. Precise material and form identification is essential because these products scatter across multiple HTS chapters with distinct duty and regulatory treatment.

Graphite electrodes used in electric arc furnace steelmaking have been subject to antidumping duty investigations and orders from certain origins. Given their critical role in domestic steel production, trade-remedy activity in this product line has been closely watched. Importers should check the current status of any active orders with the US Department of Commerce before sourcing.
Customs brokers typically request a detailed technical data sheet specifying the article's carbon or graphite content by weight, its manufacturing method (extruded, molded, or isostatic), intended end use, and physical dimensions. These details determine whether the article classifies as a carbon or graphite electrode, a carbon or graphite brush, or another form — each of which may carry a different HTS heading and duty rate.
