NOM-220-SSA1 sets the binding PV framework in Mexico. But the gap that surfaces in COFEPRIS inspections is rarely a documentation gap — it's a calibration gap. Programs built to the right standard, at the right time, that have since drifted from what the agency actually evaluates.
This checklist maps the five core PV obligation areas under NOM-220 against current COFEPRIS inspection expectations. Each item is tagged by criticality — Critical, Required, or Recommended — so your team can identify where the risk is concentrated before an inspection does it for you.
