1. What Is a GRS Certificate?
The Global Recycled Standard (GRS) is an international standard created to verify recycled materials.
It checks the source of recycled content, the percentage used in the product, and whether the entire production process follows environmental, social, and chemical safety requirements.
A valid GRS certificate means that a company has passed third-party audits, proving that:
Raw materials are traceable and come from legal recycling channels
No harmful chemicals are used during production
The factory meets social responsibility standards (no child labor or forced labor)
Proper environmental management systems are in place
2. Why Is GRS Certification Important?
With carbon neutrality, ESG, and green procurement becoming global trends, GRS is more than an environmental label—it is a guarantee of real sustainability.
GRS certification helps companies:
Build stronger brand trust and global competitiveness
Prove genuine recycled content to meet consumer expectations
Support carbon footprint tracking, ESG reports, and carbon-related regulations
3. How GRS Influences the Industry
GRS has become a requirement not only for brands but also for governments.
Many countries use “compliant supply chains” as part of their tax rules, policies, and procurement standards.
In Europe and the United States, recycled materials without GRS certification are often rejected. For recycled plastic suppliers, failing to meet GRS requirements will make international orders increasingly difficult to obtain.
4. Yung Iee Green Materials Is Already Fully Prepared
As the global supply chain moves toward sustainability and compliance, Yung Iee Green Materials obtained GRS certification as early as 2018—making us one of the first certified rPET bottle-flake producers in Taiwan.
We focus on producing rPET flakes using raw materials sourced from legal recycling systems.
Our flakes go through multiple washing and sorting processes, and we have also received the U.S. FDA NOL approval for PET, allowing use in food-grade applications. Our stable quality is trusted by both domestic and international brands.
Our strengths include:
100% traceable and transparent recycled sources, verified through GRS audits
rPET flakes that meet the specifications of major global brands
Processing over 4,500 tons of post-consumer PET bottles every month, ensuring reliable supply
Complete in-house lines for washing, sorting, color separation, and flake processing
We also hold ISO 9001 for quality management and ISO 14067/14064 for carbon footprint and greenhouse gas reporting. This helps our partners meet ESG, carbon audit, and brand compliance requirements all in one place.
GRS certification is more than a label—it is a responsibility.
It turns recycling from a slogan into a system that customers can trust from raw materials to the final product.
If you are a brand, manufacturer, or partner looking for high-quality recycled PET flakes, Yung Iee Green Materials is ready to work with you.
