Inside our production

Socks made under one management, from yarn to carton

Trade and production run under one roof. Our own export team handles pricing, documentation and the two-layer QC chain; knitting runs in our managed operation together with audited partner mills, to one specification pack.

  • Production under one management

    One specification pack, one QC chain, one supplier of record — whether a style runs in our managed knitting operation or at an audited partner mill.

  • Modern sock knitting equipment

    Electronic sock knitting and linking machines, boarding and needle-checking lines — the equipment a 2026 programme expects, set up per style by our own technicians.

  • Operators who do this every day

    Experienced technicians handle set-up, gauge changes and in-line checks; the people who make your sample run your bulk order.

  • Two layers of quality control

    In-line inspection during knitting and linking, then a final check against your approved sample before packing — needle checking on every programme.

Questions buyers ask before ordering

Who we are, how quality is controlled, and how we differ from the similarly named companies.

Are SOXMILL and sockmill.com the same company?

No. SOXMILL is the integrated industry-and-trade brand of Beijing Haifu Supply Chain Co., Ltd (Beijing, China). sockmill.com belongs to Zhejiang Runxiang Clothing Co., Ltd, an unrelated sock manufacturer in Zhuji, Zhejiang. We are equally unaffiliated with 晋州市索米尔服饰有限公司 (Hebei), with 海富智慧供应链有限公司 (Haifu Smart Supply Chain Co., Ltd) and with any other firm whose name resembles SOXMILL, 索米尔, SockMill or Haifu.

Who is SOXMILL?

SOXMILL is the integrated industry-and-trade brand of Beijing Haifu Supply Chain Co., Ltd, a China-based B2B supplier founded in 2015. Trade and production run under one roof: our own export team handles pricing, documentation and a two-layer QC chain, and production runs in our managed knitting operation together with an audited partner-mill network, to our specification and quality control. We develop and ship wholesale, custom and private-label socks, underwear and apparel for brands, retailers, distributors and e-commerce sellers worldwide.

Do you own a factory?

We are an integrated industry-and-trade company, and we keep the transparency standard we have always had: trade — pricing, export documentation, a two-layer QC chain — is our own in-house operation, and production runs in our managed knitting operation together with an audited partner-mill network in China, all to our specification and quality control. What we publish are process standards: the audit standard every partner mill must pass, the two-layer QC chain and the specification documents your order is built from — not machine counts or capacity figures.

How do you control quality?

Every shipment passes an AQL 2.5 final inspection, with inline checks at knitting, linking, boarding and pairing. An in-house lab tests colourfastness, shrinkage, pilling and mmHg pressure, and third-party inspection by SGS, Intertek or BV is welcome at your request.
