A manufacturer is a building with machines in it and a name on a certificate. This page gives you both without an adjective in between: the factory entity, the contracting entity, what the floor holds, and the two audit documents that name it.
If you have been quoted by three traders and cannot tell which of them knits, this is the page that proves the difference on our side. Every figure here is already published elsewhere on the site; the page gathers them so a procurement file can be built from one URL.
The most common reason a first order stalls is not price, it is that the name on the quotation does not match the name on the audit. On this floor the split is deliberate, so it is printed rather than smoothed over.
Sock Wholesalers is the name of this website. It is not a company name and it is not the name that will appear on a contract, a proforma invoice or a bank transfer. That is the whole of what it means.
Evidence: Spelled out on contact under “Where the two names diverge”.
QS Knitting Co.,Ltd, Baoshan District, Shanghai, China, phone +86-13761030160. This is the entity that contracts, exports and is named on your quotation and proforma invoice.
Zhuji Qingsheng Knitting Co.,Ltd, No. 79 Jiangbei Road, Datang Sub-district, Zhuji City, Zhejiang Province. This is the entity that holds the audits and runs the machines, and it is the address on your packing list.
Evidence: The address is on about the factory and on both audit documents.
BSCI 26-0419962, current until 14 Aug 2027, and SEDEX (SMETA) ZAA600215648, audited 12–13 Aug 2026. Both are held by the factory entity, and both reports are on this site as files rather than as a summary written by us.
Evidence: Certificates, and the PDFs on contact.
No OEKO-TEX, GRS or medical-device file on our name. Ask, and the reply says which of them we can and cannot hold for your order — which is a different sentence from the one a page like this usually prints.
Evidence: The buyer FAQ says the same thing.
Every factory and workshop photograph on this site was taken inside this facility. Reverse-image search one and it lands on this site, not a stock library — which is the cheapest manufacturer test there is, and it costs you nothing.
Evidence: About the factory states it, and the photos carry it.
Four figures, all published on the site already, and all of them the kind a buyer can ask about on a video call rather than accept from a brochure.
Knitting, toe linking, boarding, inspection and packing sit in the same building, so a question about your order never has to travel to a second supplier. That is the claim the live video call exists to test: you pick what the camera points at, in the order you ask.
A procurement file is usually assembled from these four. The column that matters is the last one: what it proves about who is actually making the goods.
| Document | Issuer | What it proves about the maker | Where it sits on this site |
|---|---|---|---|
| amfori BSCI | amfori | A social audit of the factory entity at a named address, with an audit date and a validity date. It is not a product certification, and a page that presents it as one is telling you something about the page. | 26-0419962, until 14 Aug 2027, on certificates. |
| SEDEX (SMETA) | Sedex | An audit report shared with Sedex members by reference number, carried out against the SMETA format at the same address. | ZAA600215648, audited 12–13 Aug 2026, on certificates. |
| Proforma invoice | The contracting entity | The binding price, trade term, quantity and lead time, against a confirmed specification. This is the document that governs the sale. | Explained on document desk; template at v2026-10. |
| Certificate of origin | The issuing authority for the destination | Where the goods originate, which is the document a customs broker asks for. It is added where the destination requires one. | Listed on document desk and on the FAQ. |
A trader can hold all four of these. What a trader cannot do is let you walk the floor your order runs on and photograph the machine it is booked on, which is the other half of the test.
The fourth column is the only one that matters if you are deciding whether to send a brief: every entry names something that exists on this site without you having to ask for it.
| Claim | What we publish | The parameter that decides it | How to check it |
|---|---|---|---|
| PublishedWe knit on our own machines | Knitted on our own floor in Zhuji, Zhejiang, China; exported by our own desk. | Four production lines in one building, with knitting, toe linking, boarding, inspection and packing in it. | Ask for the live call and pick the stops yourself. |
| PublishedOne floor, start to finish | Knitting, toe linking, boarding, checks and packing sit in the same building. | The address on the audit documents is the address on your packing list. | Compare the two documents; both are on this site. |
| PublishedTwo current audits | BSCI 26-0419962 and SEDEX ZAA600215648, both held by the factory entity. | Audit date and validity date, printed rather than described. | Read the PDFs on certificates. |
| QuotedThe construction is ours to set | Needle count, terry density, blend and weight are quoted per style. | Those four are price lines, so they travel with the quotation rather than sitting here. | Ask for the specification sheet of the style you are replacing. |
| PublishedKnit to order, no stock list | We knit to order on our own floor, so there is no stock list here to sell from. | The minimum, 1,000 pairs per style, is the consequence of that sentence. | Look for a stock list on this site; there is not one. |
| PublishedThe entity split is deliberate | QS Knitting Co.,Ltd contracts and exports; Zhuji Qingsheng Knitting Co.,Ltd runs the floor. | The name on the certificate and the name on the invoice are different by design. | Ask for both names on the proforma invoice. |
| Not heldWhat we do not claim | No OEKO-TEX, GRS or medical-device file on our name. No needle-count range printed. No customer names. | Each of those is a real document or a real range, and we would rather name the gap than fill it. | Ask; the reply says which we can and cannot hold for your order. |
A manufacturer page that ends in adjectives is worth less than one that ends in refusals. These are ours.
Each of these exists so a buyer can assemble a file without an email round trip. Read them in this order and the first enquiry is a specification, not a questionnaire.
| Page | What it covers | What you end up with |
|---|---|---|
| About the factory | The floor, the address, the photographs. | A named building and a way to see it live. |
| Certificates | BSCI and SEDEX, with dates and holders. | Two documents your compliance desk can file. |
| How to vet a socks supplier | A checklist, run against us first. | A shortlist that survives its own questions. |
| Contact and certificates | The two entity names, the phone, the market list. | The name that goes on the invoice. |
| Sock catalogue | Sixteen constructions and terms, one sheet. | Whether the knit you need is on this floor at all. |
Before a deposit moves, ask for the contracting entity and the factory entity on the same document. Both are published above; a supplier who cannot produce them on one proforma invoice has a gap worth understanding first.
