Which code does this activity belong in?
NAICS 33281 covers establishments that perform surface treatment, finishing, and decorative services on metal products made by other manufacturers. The code includes heat treating, electroplating, galvanizing, powder coating, enameling, and engraving services. The boundary separates this code from NAICS 3327, which covers machine shops that machine metal parts on a job or order basis; NAICS 33281 handles finishing operations after fabrication rather than the primary machining or forming processes that produce the metal products themselves.
