Last updated: April 2026 dataWork rolls, backup rolls, and other replacement parts for metal-rolling mills are traded under SITC 73729 and represent a high-volume, recurring procurement category for steel and aluminum producers worldwide. Rolls are consumable items — they wear and must be periodically reground or replaced — making supply continuity and roll material specifications (forged steel, cast iron, high-speed steel) central concerns for mill operators. Importers should note that forged steel rolls may independently attract antidumping scrutiny depending on origin, separate from any Section 232 exposure on the steel content.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Antidumping duty orders on certain forged steel rolls have been in place against specific countries at various times. Importers must check the current scope of any active antidumping orders with the US Department of Commerce and USITC, and separately assess Section 232 applicability, as both measures can apply simultaneously depending on origin and product specification.
While SITC 73729 groups rolls together, HTS classification at the 10-digit level distinguishes rolls by material (cast iron versus forged steel versus other) and by the type of mill they serve. Importers should document the roll's material composition, manufacturing method (cast or forged), and the specific mill type to support accurate HTS classification and any antidumping scope analysis.
