Sumitomo Forestry Co., Ltd. launched in May 2015 full-scale sales of original wooden fire-prevention doors, made from “balsa” known as the lightest timber in the world, which are lighter, less-expensive and more attractively-designed than existing products.

Safety and Quality Control in Overseas Manufacturing Business

Basic Policy and Framework for Safety and Quality Control

Group companies engaged in the manufacture of wood building materials overseas have acquired quality certifications such as ISO 9001, Japanese Industrial Standards (JIS) and Japanese Agricultural Standards (JAS). In line with the requirements of these certifications, each company has established policies and standards for quality control, and through education and training, strives to ensure that its employees understand them well. Furthermore, each company is making ongoing improvements to quality control management systems by means of annual certification audits through external organizations as well as periodic internal audits.

The quality standards of every company are being further improved to provide greater safety by focusing on communication and feedback from users about product safety and quality, especially in the production of products for Japan which demands the utmost safety and quality.

Updating to ISO9001:2015

Six consolidated companies have completed their update to ISO9001:2015: Nelson Pine Industries (NPIL), Kutai Timber Indonesia (KTI), Rimba Partikel Indonesia (RPI), AST Indonesia (ASTI), Canyon Creek Cabinet (CCC), and Vina Eco Board (VECO).

Under the new quality management system, we will move forward with even greater continual improvement, maintaining and increasing the safety and quality of our products.
