 Introduction

Qua-City is a unique engineering organization in China to provide TOTAL QUALITY ASSURANCE engineering services to support:

  • Oversea buyers of mechanical products from China
  • Oversea seller of mechanical products to China
  • Local Chinese mechanical product manufacturer in quality improvement

Critical difference between Qua-City & other laboratories:
BATCH CONSIGNMENT INSPECTION

Other laboratories conduct inspection and testing only on factory provided samples. The concern is whether or not these selected samples are representative of the entire lot purchased.

Qua-City understands your need and therefore all of our operation is geared to provide Batch Consignment Inspection that we select from the entire shipment as it arrives in our controlled warehouse. Our in plant 1,800 sq meter warehouse enables us to pick an “ISO” standard appropriate number of random samples to make sure the samples represent the entire shipment.
