Sedex Members Ethical Trade Audit (SMETA)

Sedex Members Ethical Trade Audit (SMETA) is a widely recognised global social compliance scheme. Based on the Ethical Trade Initiative (ETI) Base Code, SMETA is the Sedex Members Ethical Trade Audit methodology that a business can use to monitor its supply chain by assessing the risk in a supplier’s working conditions across the areas of labour, health and safety, environment, and business ethics.  

NSF is an Affiliate Audit Company (AAC) of Sedex. Sedex is one of the world’s leading collaborative platforms for buyers and suppliers to store, share and report on ethical and social audit information quickly and easily. Being granted AAC approval indicates NSF’s commitment to correctly using ETA (Sedex Members Ethical Trade Audit), the Sedex social audit methodology, and to conducting audits with quality and integrity.

Sedex has more than 55,000 members in 180 countries, and its AACs have conducted over 280,000 audits worldwide. NSF can guide you through the process, assisting you with your self-assessment or conducting your audit to demonstrate your adherence to good labour, health and safety, environmental, and business practises.

Sustainability Initiative of South Africa (SIZA)

This holistic offering identifies problems, usually through an independent third-party audit, and provides appropriate support and interventions, including awareness-raising and relevant capacity-building programmes. SIZA is a South African social compliance standard developed, owned and operated in South Africa but aligned to global best practises for supply chain monitoring of labour, health and safety, and working conditions. SIZA also operates in Namibia.

The programme aims at monitoring compliance and focuses on continuous improvement. Its objective is to encourage continuous improvement in practises over time, going beyond the minimum legal requirements. SIZA engages directly with our stakeholders throughout the value chain to manage risks and identify needs and issues. Interventions and support tools are created by measuring member compliance over time. SIZA provides a platform for agricultural stakeholders to ensure ethical sustainable trade. SIZA social audits can also be visible on other platforms, like Sedex Advance. SIZA is benchmarked against Sedex.

The Wine and Agriculture Ethical Trade Association (WIETA)

The Wine and Agriculture Ethical Trade Association (WIETA) is a South African social compliance code that can be used to drive a proactive and sustainable ethical trade programme for the South African wine industry and related sectors. The Ethical Code of conduct serves as a rigorous framework through which its members and their supply chains are monitored. Social audits not only serve as a primary monitoring tool to measure legal compliance with South Africa’s labour and occupational health and safety legislation, but also go beyond compliance requirements to ensure that a company’s management systems reflect sustainable, ethical principles, policies and practises. 

GLOBALG.A.P. Risk Assessment on Social Practise (GRASP)

This is a risk assessment of social practises on the farm, focused on workers’ health, safety and welfare. Designed to complement GLOBALG.A.P. certification, GRASP has helped 50,000-plus producers upgrade their good social practises, assess their social management systems and demonstrate their compliance to their buyers.
