Certifications

In Mayflower's extensive range of yarn, there is a wide selection of qualities with different certifications, all of which have in common that they are voluntary labeling schemes with high international standards, each imposing high and specific requirements on, for example, animal welfare, work environment, human rights, harmful substances, the production chain, and the finished product. 

At Mayflower, we are constantly working to obtain as many certifications as possible to promote transparency and insight into the production chain that precedes the yarn we sell. This gives you the opportunity to make an informed choice, and it gives us an opportunity to influence the entire production chain as much as possible through the high demands, laboratory tests, and controls of the certifications.

GOTS – GLOBAL ORGANIC TEXTILE STANDARD

GOTS is the world's leading standard label for organic fibers for yarn and textiles. The certification is voluntary and has strict criteria and requirements for producers in the following areas:
