RCS
(Recycled Claim Standard)

The Recycled Claim Standard (RCS) applies to products that contain at least 5% recycled raw materials. It is designed to ensure the continuity of managing recycled raw materials and finished products containing the same. The entire process is subject to audit, from raw material collection and processing to finished product manufacturing and sales. By obtaining this certification, producers and distributors of RCS-certified products can ensure that their production and management structures are consistent and transparent. In addition, by promoting the use of recycled materials, a company can reduce environmental damage resulting from production activities and improve its social standing.

(Global Recycled Standard)

GRS is a certification standard that verifies the utilization of recycled materials in textile raw materials and apparel production. Targeting products containing at least 20% recycled raw materials, the standard ensures the continuity of management through process review at all stages, from raw material collection and processing to sale of finished goods. GRS-certified product manufacturers and distributors must adhere to the organization's social, environmental, and chemical standards, and obtaining certification ensures that production and management structures are consistent and transparent. Increasing demand for GRS certification encourages the use of recycled materials, thereby reducing environmental damage resulting from production activities and contributing to the enhancement of corporate social standards.
