Our trader audit was launched back in 2017 to help assess traders of part-processed leather material, designed to provide better transparency and assurance to the leather supply chain. Since then, we've expanded the scope of the standard to also allow traders of finished leather and raw hides/skins to obtain a 12-month LWG Trader Certification. 

The LWG Trader Audit helps you to understand how much material a trader buys from LWG-certified leather manufacturers, stores, and sells. The data obtained during a trader audit can be input into a leather manufacturer's own audit, using the LWG Leather Manufacturer Audit Standard.

The LWG Trader Audit Standard covers six separate sections:


Purchasing Raw hides/skins, part-processed material, and finished leather
Selling Raw hides/skins, part-processed material, and finished leather

Only a trader operating from a physical warehouse is eligible for audit. The warehouse may be owned or rented by the trader, it must be physically segregated from other businesses, organisations, or activities, it must be identifiable through a unique address, which must be indicated on documentation associated with despatches from the site. Access to the facility must be controlled by the trader and the warehouse must be operated by the trader with their own employees.

Any trader not meeting these requirements, is, within the scope of the LWG audit, regarded as an agent trader and not eligible for audit.

Separation Must be able to demonstrate physical and documented separation of material that originates from LWG-certified vs. non-certified facilities
Suppliers Can give details of all suppliers, including quantity supplied from each, and contact details
Customers Can give details of all customers, including quantity supplied to each, and contact details
Minimum thresholds of LWG Material supplied*

To be eligible for an audit and certification, the trader must meet one of the conditions below:

Have suppled more than 300,000 m2, 300,000 pieces or 2,000 ton of LWG origin material in the data period to be included in the audit


The quantity of LWG origin material traded exceeds 50% of the total volume traded in the data period to be included in the audit

* Minimum threshold requirements were introduced with effect from 1st March 2023

Traders that do not own and operate their own physical warehouse where material is received into or dispatched from cannot be audited using the LWG Trader Audit Standard. These companies may be eligible to join LWG through our membership route, where they would be classified as an 'Agent Trader'. However, please keep in mind that this membership does not confer any form of certification and therefore cannot be used by leather manufacturers during the course of their own audit under the LWG Leather Manufacturer Audit Standard.

Audit Scope

The LWG Trader Audit Standard was designed to assess the system by which a trader tracks material coming into their warehouse, ensuring their systems are robust, monitoring material origin, and understanding the LWG certification status of their supplier or feeding into the LWG certification process of their customers.

Length of audit: 1-day on site
Certification validity: 12-months
