Last updated: April 2026 dataRolls are the consumable working elements of rolling mills — cylindrical tools that apply compressive force to reduce metal thickness or shape profiles — and their classification depends on both material composition and unit weight. The US schedule subdivides this heading into gray iron rolls and cast steel rolls, each further broken by weight thresholds (not exceeding 2,268 kg; 2,268–6,803.9 kg; exceeding 6,803.9 kg), plus NESOI categories, spanning tariff lines 8455300005 through 8455300090. Germany and Brazil lead US supply, with Japan, Austria, and France also prominent — a supplier mix that reflects the specialized metallurgical casting capabilities required for high-performance mill rolls. Rolls subject to antidumping or countervailing duty orders from specific origins should be verified against current Commerce Department scope rulings before entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The US tariff schedule breaks rolls into weight brackets — not exceeding 2,268 kg, between 2,268 and 6,803.9 kg, and exceeding 6,803.9 kg — because duty rates and trade-remedy exposure can differ across these brackets. Importers must verify the actual unit weight of each roll against the certified shipping weight to select the correct 10-digit line.
Rolls that are not gray iron and not cast steel fall into the NESOI (not elsewhere specified or included) lines within 845530, again subdivided by weight. The material composition should be documented with a mill certificate or metallurgical test report to support the classification and to respond to any CBP inquiry about whether the roll might instead be a forged or machined roll classifiable elsewhere.
