Third-party certification bodies, such as SGS, BV, TUV, HKQAA, etc. , you can carry out SA8000 certification (that is, your so-called inspection).
If your company's fraud is perfect and the auditors can't find it out, it's entirely your company's problem, and the auditors are not the police who solve the case. If you think the company is fraudulent, you can collect evidence and complain to the certification company, provided that you find out which company certified you. A certification company may suspend its SA8000 certificate.
