01 About OID
A team that knows Chinese factories from the inside.
“The bad guys — 20 years of experience.”
OID is a quality control and product development company based in Foshan, in the manufacturing heart of Guangdong. For more than twenty years our people have worked on the production floor on behalf of international companies.
We check materials, processes and finished goods; we identify the root causes of defects and implement corrective measures; we verify suppliers before contracts are signed and watch containers being loaded before goods leave China.
The work is carried out by qualified inspectors and technicians, constantly updated on industry regulations and best practices — with tailored solutions for the cold sector (refrigeration).
Best quality, better life.

QA / QC What we do
We work on the product, where quality is decided.
We make sure every product meets the highest standards of quality, safety and compliance — through targeted inspections, analysis of production processes, and checks on materials and finished products.
Quality Control is fundamental in every production line. It is part of a broader Quality Management system, where Quality Assurance monitors and manages production processes to ensure compliance with regulations and corporate requirements. The QC department intervenes directly on the product, performing continuous checks and tests for constant reliability, safety and performance.
The goal: prevent defects, reduce waste and improve customer satisfaction — with reliable, consistent results.
