Recently, Rainbow Offshore successfully passed the Japanese JIS certification audit, becoming one of the few domestic marine engineering equipment companies to have obtained this certification. This achievement follows the acquisition of international certifications such as the American ASME, EN1090-EXC4, and ISO3834-2, further accelerating the pace of Rainbow Offshore's international development.

Rainbow Offshore attaches great importance to JIS certification and has rigorously adhered to the requirements for application and preparation. The audit team actively cooperated with the review team to conduct product quality testing and factory acceptance. A series of tasks including product design, raw material procurement, and product testing were completed successively, ultimately leading to the certification.

The JIS (Japanese Industrial Standards) is a set of industrial standards established and reviewed by the Japanese Industrial Standards Committee (JISC), one of the world's top ten standardization organizations. It is the most important and authoritative certification standard in Japan's national standards and is also recognized internationally as one of the highest-level system standards. In addition to testing product quality and performance, JIS certification also involves strict scrutiny of the factory to ensure its capability to continuously and stably produce qualified products.

The certification signifies that the product quality and management level of Rainbow Offshore have reached international standards, holding profound significance for the company's future expansion in the Japanese market and enhancing its competitiveness in the international market.

Adhering to high standards is an unwavering pursuit of Rainbow Offshore. The company emphasizes the establishment of a product quality management system and maintains strict control over quality and production processes to ensure the provision of high-quality products and services to global customers, persistently striving to create benchmark products in the industry.
