Process for handling requests for information, complaints and appeals


Other than complaints and appeals, we can be contacted via email: or by phone at 6660 7682.

Handling of complaints

All complaints shall go to General Manager who will designate a manager (if the Department Manager is involved) who is independent of the activities related to the complaint, to further investigate the complaint.

Department Manager shall acknowledge all received complaints in writing, ensuring confidentiality to the complainant and the subject of complaint, ensuring submission, investigation and decision on complaints do not result in any discriminatory actions against the complainant. All written & verbal complaints shall be recorded in Complaints Log

Any valid complaint is related to a certified client, Department Manager may bring the complaint to the attention of the certified client as appropriate and review all necessary information to examine the effectiveness of the certified management system of the client.

If the complaint is related to certification activities that STS is responsible for, Department Manager shall consider following course of action:

a)         Initiating corrective/ preventive action;

b)         Calling for meeting with General Manager to discuss significant complaints;

c)         Rejecting the complaint if deemed to be unreasonable or impracticable.

The final decision to be communicated to the complainant shall be approved by General Manager and Department manager shall keep the complainant informed on the progress & outcome of action taken.

Complaints that are not closed out within a timeframe documented and agreed with the complainant shall be escalated to STS General Manager to ensure that the complaint receives the appropriate priority. Complaints that are not closed out within three (3) months of that agreed timeframe shall be brought to the attention of accreditation body (JAS-ANZ/SAC).

If a complainant is dissatisfied with the final outcome of the STS Certification’s complaints handling process, the complainant may refer the complaint to accreditation body (JAS-ANZ/SAC). The Department manager may take into account the recommendations made by accreditation body and issues its decision with the approval of General Manager, which shall be final.

If the issue under dispute has potential to affect the certification decision, Department Manager shall give certified client the opportunity to raise an Appeal which shall go through the appeals handling process. STS would determine, together with the client and the complainant, whether and, if so to what extent, the subject of the complaint and its resolution made public.

Department Manager shall settle all valid outstanding complaints and update the Complaints Log (in spreadsheet format).

If corrective/preventive action has been initiated, the Complaints Log shall be updated with related corrective action/ preventive action form number.
