Carrefour, as an international super retailer, has high social responsibility requirements for itself and its suppliers. Carrefour will carry out a series of assessments on its partners when selecting them, which we usually call "Carrefour factory inspection". Factory inspection is mainly conducted by a third-party audit agency, and sometimes carried out by Carrefour's own audit department. The content of factory inspection is mainly to audit the social responsibility and quality management system of the factory. The audit results are divided into four levels: ABCD. The AB level is acceptable. The C level needs follow-up audit while the D level cannot cooperate with Carrefour. Carrefour audits suppliers according to ICS standards. Generally, an official report will be submitted to the factory within 15 working days after the factory inspection.
