Inspection is planned against the signed project specification, approved drawings and inspection and test plan. Typical checkpoints can include material records, routine tests, dimensional checks, accessories, markings, packing and document completeness.

Depending on the contract, inspection may be performed by the selected factory, witnessed by the buyer, or assigned to an independent third party. Reports and certificates remain attributable to the manufacturer and the inspected project. YUHENG HEAVY coordinates schedules, document exchange and issue follow-up.
