Sika also assumes responsibility for the supply chain. Since 2015, the Supplier Code of Conduct, introduced in 2013, is binding for all new suppliers and is gradually being extended to existing suppliers. The agreement was endorsed by a total of 5’165 suppliers. Sika thereby ensures that suppliers are informed of Sika’s ethical, environmental, and social expectations and guidelines and that they carry out their processes in compliance with the Sika sustainability criteria.

Sika introduced a group-wide process that maps out the main sustainability principles (economic, social, and ecological) for supplier qualification and evaluation. The multi-stage supplier evaluation process has three central elements: It starts with the commitment to comply with the Supplier Code of Conduct and the completion of a self-assessment formulaire. In unclear cases, the purchasing department will follow up with sustainability audits before concluding a supply contract. Sika continued to implement this process globally in 2017 with a special attention to new suppliers in high-risk geographic regions and industries.

Documentation generated during supplier qualification is transparently recorded and stored on a dedicated platform. The system enables buyers to inspect suppliers’ qualifications and improve them in their countries as necessary.

Sika continued the implementation of its worldwide process that  map out the main sustainability principles for vendor qualification and evaluation (multi-stage vendor qualification process). Also in 2017 procurement employees in the company have been trained using a systematic supplier audit method. These procedures are designed to ensure compliance with international labor standards and prescribed quality, environment, safety, and health criteria.

Sika has been implementing this process globally in 2015, collecting evidence and documents on a newly created globally available platform. However, as Sika applies a risk-based approach, companies reporting according to GRI on human rights criteria, and signatories of the UN Global Compact and the OECD Guidelines for multinational companies will not necessarily be screened.
