What is it?

Quality control verifies product conformance to specifications through incoming, in-process, and/or pre-shipment inspections, often using statistical sampling plans.

Important Terms

Keep definitions operational: name places/ports, dates, document triggers, and cash milestones — avoid naked acronyms in contracts.

Why does it matter?

QC failures after arrival are ten times costlier than catching them at origin. Tie inspection release to balance payment whenever risk is material.
