Which code does this activity belong in?

Metalworking machinery manufacturing covers establishments that produce machine tools for cutting and forming metal, along with their accessories, dies, jigs, fixtures, industrial molds, and related equipment like rolling mill and wire drawing machines. This sector is distinct from agriculture and construction machinery manufacturing, which focuses on farm equipment, construction equipment, and mining machinery rather than tools designed specifically for metalworking operations.
