Supplier Code of Conduct
Sika takes responsibility for sustainability along the value chain and includes suppliers. Since 2015, the "Supplier Code of Conduct", introduced in 2013, is binding for all new suppliers and is gradually being extended to existing suppliers. End of 2018, the agreement was endorsed by a total of 6,936 suppliers (+34% vs. 2017) and meanwhile covers 81% of the value of direct spend. 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.
Supplier qualification and evaluation
Sika’s group-wide process maps out the main sustainability principles (economic, social, and ecological) for supplier qualification and evaluation. The multistage 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.
Documentation generated during supplier qualification, like audit and visit reports, supply agreements and specifications, 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.
