Water on an inner wall may not be a leak; check product, packaging and wash moisture too.

Separate the source

Observe product starting condition, wet packaging and container dryness separately.

Inspection sequence

  • First wet area and time
  • Product starting state
  • Packaging and container surface
  • Lid openings

Interpret the finding. If wetness increases with openings, review handling; if it recurs at one closed point, inspect joints and drainage.
