Certifications

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

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