Ueyama Group / Ueyama Textile Co., Ltd. (Moriguchi City, Osaka; CEO: Noriyuki Ueyama) has obtained the 'OCS (Organic Content Standard)' international certification for organic textile products. With this achievement, the company has established a system in the Banshu region capable of supplying OCS-certified fabrics through a supply chain that includes everything from weaving to dyeing and distribution.
This certification was issued by the certification body IDFL (International Down and Feather Laboratory). Within the Ueyama Group's production system, the certification covers the following processes:
- Trading: Ueyama Textile Co., Ltd.
- Weaving, Sizing, and Warehousing: Ueyama Orimono Co., Ltd.
- Dyeing and Pre-treatment: Toban Dyeing Co., Ltd.
As a result, an integrated supply system for organic textiles has been realized through a collaborative supply chain within the Banshu region.
In recent years, the apparel industry has been identified as one of the industries with a high environmental impact, and there is a growing demand for environmental consideration and traceability throughout the supply chain. In particular, the cultivation of cotton, a major raw material, has been pointed out for issues such as water consumption and pesticide use.
Against this background, the global demand for products using organic raw materials is rising, and the importance of international certification systems that manage the history from raw materials to products is increasing.
## What is OCS (Organic Content Standard)?
OCS (Organic Content Standard) is an international certification system for the supply chain of products containing organic fibers. It certifies that rigorous management is in place at each stage from raw material harvesting to the final product (weaving, sizing, dyeing, finishing, warehousing, etc.) to ensure:
- Verification of the content percentage of organic fibers
- Management systems to prevent mixing or contamination
- Ensuring traceability
This certification covers textile products made from organic cotton, such as:
- Yarn-dyed fabrics
- Undyed fabrics
- Greige (unfinished) fabrics
