NAICS codes for machine shops, without pretending they are the whole story
332710 and related codes matter, but capability, certifications, and constraints decide whether a notice is pursuable.
Machine shops often appear under NAICS 332710 (Machine Shops) and adjacent codes for fabricated metal, aerospace parts, or contract manufacturing.
NAICS is a useful filter and a weak ranking signal on its own. Two shops with the same code can have completely different machines, materials, and certifications.
Use NAICS to get into the right neighborhood. Use a capability profile to decide whether the work belongs on a pursuit list.
