Organic Socks Manufacturer in China
FOCS is an organic socks manufacturer based in Shanghai, China, producing GOTS certified organic cotton, organic wool, bamboo and hemp socks for brands across Europe and North America. With 600 knitting machines spanning 84N to 240N gauge, we cover everything from chunky organic rib socks to 240-needle fine-gauge dress socks ā all under one roof, one QC system and nine international certifications.
Sourcing organic socks from China is not risky when your supplier holds the certifications itself. FOCS runs segregated organic production lines, documents every yarn lot, and issues GOTS transaction certificates with each order ā the paperwork your own certification audit will ask for. Our organic programme spans organic cotton crew socks, organic baby socks in OEKO-TEX Class I grade, organic tights, bamboo socks and hemp socks.
Two decades of exporting to Nordic and Western European brands means we already work the way your compliance team expects: pre-production samples, in-line inspections, color fastness reports, and packaging in recycled or FSC-certified materials. Around 28% of our factory's electricity comes from rooftop solar, and our social compliance is audited under BSCI ā details that matter for your ESG claims under the EU's greenwashing rules.
Whether you need 500 pairs to test a market or 50,000 pairs for a retail program, you get the same factory-direct pricing, the same certified organic yarn, and a single point of contact who answers within one business day.
