This edition features the company Sivanthi Joe Coirs in our series “RHP Stories: Committed to Quality.” In this series, we highlight certified companies and invite them to share what RHP certification means to them and what it has brought to their business.
“Since 30 January 2006, we have been RHP Horticulture certified for our coir products, both as substrate raw materials and as substrates. Certification has resulted in a solid internal quality system based on objective standards, enabling us to consistently maintain our quality. As RHP requirements evolve in line with developments in horticulture, we remain ‘state of the art’.”
“RHP certification has strengthened our quality control and provides access to expert knowledge and technical support from RHP as the knowledge center for substrates. It facilitates easier access to international markets such as the USA and Australia. In addition, RHP statements support us in other markets. Through training and consultation, RHP also helps keep our technical team up to standard.”
“Customers and growers recognise RHP certification as an independent quality standard for growing media. Many growers and traders value or specifically request RHP certification. It provides assurance and, in some cases, aligns with the grower’s own certification requirements.”
“We are proud to be the first coir company outside the Netherlands to obtain RHP certification for coir products, and the first outside Europe for end product substrates. We are pleased to be part of the group of leading substrate (raw material) producers in the world operating at the highest quality level, which we strive to achieve every day.”
“We have developed a new product, Coco Pro Coin, which is currently under RHP review. In developing this product, we were able to use the tools developed by RHP. These tools that align well with current grower requirements.”
“In our view, there is still an opportunity to increase awareness and understanding of what the RHP quality mark for coir products represents among new customers.”
