We launched the current version of the LWG audit standard (P7) in 2021, marking a major advancement in our assessment of leather manufacturers and supporting a more sustainable and secure leather supply chain. This updated, holistic audit now emphasises a comprehensive ESG approach, encompassing all aspects of responsible leather manufacturing, including environmental management, traceability, chemical management, social responsibility, and governance.
Audit Scope
The LWG Leather Manufacturer Audit Standard was designed to assess facilities processing leather from raw, crust, tanned material into pre-tanned, tanned, crust, or finished leather. You can view those operations here.
It covers 17 separate sections and certification is valid for two years. Learn more about its remit here.

CETP of Concern
CETP of Concern
| Date Recorded (last updated) | Industial area / CETP Concerned | Comments | Auditor(s) |
| 17 Jan 2023 | TALCO Dingigul (Dingigul CETP) | This CETP is functional with satisfactory compliance, demonstrated compliance to conditions of consent orders, during approved LWG audits undertaken November 2022. Approved LWG auditors visited the CETP and checked the manifests of the hazardous waste disposals as well as ensuring hazardous wastes are in secured storage before disposal. Currently there seem to be no issues. Need to monitor continuously. | Viswanathan Munusamy / Belaji Velu |
| 17 Jan 2023 | Vanitec CETP | During September 2017, the CETP (Vanitec) appeared in local media regarding non-compliance issues. This prompted the authorities to undertake an inspection at the site, only to find it was compliant. Additionally, an Approved LWG Auditor undertook an LWG CETP assessment in 2018 as a pilot case audit at the CETP. The reports were accepted. Further to this, there have been several audits undertaken by Approved LWG auditor at leather manufacturing sites connected to the CETP, and the CETP has also been visited on many audit occasions. The CETP seems to be operating well within the permit condition. Currently there seem to be no issues. | Viswanathan Munusamy |
| 17 Jan 2023 | Pallavaram Tanners Industrial Effluent Treatment Company | This CETP was under expansion with additional tertiary processing and obtained an exemption for the discharge limits on TDS from the CETP. The TNPCB extended its permission until 31/03/2023. An LWG Approved Auditor recently visit the CETP in connection with an audit (Gemini Enterprises). The CETP seems to be improving constructively, currently there seems to be no issues. | Viswanathan Munusamy |
| 01 Sep 2023 | Savar and Hazaribagh area | LWG will not permit any audits to be undertaken in the area of Hazaribagh due to the relocation of tanners from this area, Due to the ongoing problems associated with the Central Effluent Treatment Plant (CETP) in Savar, LWG will not permit the auditing of any facility connected to that CETP. A facility located within the Savar CETP catchment that is not connected to it may be eligible for audit. The facility must demonstrate it has an independent effluent treatment plant of sufficient capacity for the treatment of the effluent produced and be able to provide test reports and records to show legal discharge of effluent and disposal of all wastes. | |
| 26 January 2022 | Challawa, Sharada, and Bompai industrial areas of Kano, Nigeria | The reason for adding these areas as being of concern is an article published in EnviroNews Nigeria entitled “NESREA seals 12 industries in Kano, five in Adamawa, two in Kwara” accessible via https://www.environewsnigeria.com/nesrea-seals-12-industries-in-kano/. It is understood that some tanneries have their own WWTP so it is not a blanket ban, only for those discharging to a CETP. Any proposed audit of a tannery in one of the three industrial areas indicated should first be approved by LWG. | |
| 16 February 2023 | Gerede Leather Industrial Region (Bolu City, Turkey) | The region has resolved some of the issues listed previously from 2021 but is still working on the waste storage areas mentioned then. There does not seem to be any solution for all the issues, at least for the next 6 months (July 2023). The warnings remain in place. | |
| 4 July 2024 | M/s Ranipet SIDCO Finished Leathers Effluent Treatment Company | Closure notice has been issued for the Ranipet SIDCO CETP. No audit or certification of facilities will be permitted of facilities connected to the Ranipet SIDCO CETP until it has been shown to operating legally and removed from the list of concern. | |
| 5 July 2024 | M/s SIPCOT-SIDCO Phase II Entrepreneur Finished Leather Effluent Treatment Co | Closure notice has been issued for the SIPCOT SIDCO CETP. No audit or certification of facilities will be permitted of facilities connected to the SIPCOT SIDCO CETP until it has been shown to operating legally and removed from the list of concern. |
