Frequently Asked Questions

What is GRS certification?

The Global Recycled Standard (GRS) is an international, voluntary standard that sets requirements for third-party certification of recycled content, chain of custody, social and environmental practices, and chemical restrictions.

What’s the difference between pre-consumer and post-consumer recycled yarn?

Pre-consumer waste comes from manufacturing scraps, while post-consumer waste is made from used products like plastic bottles. Both reduce landfill waste and resource consumption.

Can I request custom colors or specifications?

Yes, we offer customized dope-dyed and spun yarns in various deniers, twists, and colors. MOQs apply based on product type.

What are the lead times for bulk orders?

Typical lead time is 20–30 days after order confirmation, depending on product and quantity. We prioritize fast and reliable delivery.

Do you provide samples?

Yes, free samples are available upon request. Please contact us with your requirements and shipping address.
