The flash line you are quoting is one business line of one Shenzhen entity. Here is what that structure means for your contract, your contact, and where your data and enquiry actually route.
TL;DR
The flash memory catalogue you are reading is one business line of one registered company: Shenzhen Wintel Digital Technology Limited (深圳市微盛鑫数码科技有限公司), registered on 12 May 2015. The same legal entity also operates separate domains for its other product lines, but your flash enquiry, your contract and your contact all stay inside this line. That structure matters because it decides who signs the invoice, who answers your email, and where your artwork and data are handled. It also means you are not dealing with three different companies that happen to share a logo. This article explains the practical consequences — and the cases where a multi-line supplier like us is the wrong shape for your order.
One name on the paper, not three
A contract needs one counterparty. When you order flash products from this site, the company that prints on your invoice and the company whose name sits on the sales contract is Shenzhen Wintel Digital Technology Limited. Not a trading alias. Not a reseller standing in front of a factory it does not own. The registered Chinese name is 深圳市微盛鑫数码科技有限公司, and that is the name a court or an arbitration body would recognise if anything ever went wrong.
Buyers sometimes assume that a supplier running more than one web domain must be several companies sharing a brand. It usually is not. In Shenzhen manufacturing it is common for one registered entity to run several product-line sites, each aimed at a different customer group. The risk is not the structure itself. The risk is not knowing which name you are actually contracting with. We state ours plainly so there is nothing to guess.
Why one entity runs more than one domain
A single factory can serve very different buyers without mixing them. Our flash line (this site) sells configurable TF cards, UDP (USB Disk in Package) modules and semi-finished boards to electronics and device manufacturers. The same entity also operates separate domains for its other business lines — different catalogues, different order flows, different product categories that have nothing to do with flash memory. Keeping them on separate domains is a clarity choice, not a way to hide anything.
Those sister domains are not this flash line, and your enquiry here does not route into them. If you came looking for the other product lines, this is the wrong entry point and you should not expect a flash quote to cover them. We keep the lines separate so the person quoting your storage order works from storage specifications, not from a catalogue they do not stock.
What “one entity, several domains” means for your order
Four consequences are worth stating before you send a purchase order.
The contract party is fixed. Regardless of which of our domains you first landed on, a flash order is placed with Shenzhen Wintel Digital Technology Limited. The invoice, the contract and the shipping documents all carry that one name. You are not accidentally contracting with a different company because a logo looks familiar across sites.
Your contact is one person. Flash enquiries go to Cathy, our business contact. Her email, mobile, office line and WhatsApp/WeChat are published on the contact page. The domain records and social profiles behind this site sit under the same entity, so the website, the registry entry and the person answering your mail all trace back to one company.
Your artwork and data stay in the flash line. Specifications, logos and order files you send for a flash programme are handled within this business line’s workflow. They are not floated across to the other product lines. If your procurement requires a clear data-handling boundary — and for IP-sensitive buyers it should — that boundary is the line between business lines, not a wall we have to build after the fact.
Your certification question is answered the same way for every line. We have not published third-party certification scans or independent test reports, and that gap is the same across the entity. We will not attach a certificate file we cannot produce the original of. If a scan is a hard gate at RFQ stage, ask for it and verify the file number with the issuing body; if we cannot supply it, that is a reason to look elsewhere, not a reason to assume the worst.
The facts that tie back to one place
Corporate structure is a claim until you can check it. Here is what ties this catalogue to a single, locatable entity, and what you can verify:
- Legal entity: Shenzhen Wintel Digital Technology Limited (深圳市微盛鑫数码科技有限公司).
- Registered on 12 May 2015, at Room C727, Innovation Plaza, No. 2007 Pingshan Avenue, Pingshan, Shenzhen.
- Production at Bantian 3rd Industrial Zone, Longgang District, Shenzhen — a 5,000 m² site.
- Product facts you can measure on a sample: the TF card is 15 mm × 11 mm × 1 mm and 0.25 g; the UDP module is 11.3 mm × 24.8 mm × 1.45 mm and 0.819 g; the semi-finished board is 12 mm × 44 mm × 4.5 mm and 3.2 g.
Put a TF card on a scale and it should read 0.25 g. Measure the UDP module and the envelope should come back at 11.3 mm × 24.8 mm × 1.45 mm. These are the same kind of checkable claim as the registry entry: either the document or the measurement matches, or it does not. A supplier built from checkable facts is easier to trust than one built from adjectives, and the structure above is the frame those facts hang on.
When a multi-line supplier is the wrong fit
We would rather tell you now than have you discover it after samples land.
If you actually need the other product lines, not flash memory, this site will not serve you. The sister domains carry their own catalogues and their own order process; a flash quote here cannot reach them, and we will point you to the right entry point rather than pretend to cover both.
If your procurement policy requires a single purchase order to span two unrelated product lines from one supplier, the separate-domain structure works against you. Consolidating flash and a different product category under one PO across our lines is not something we set up to do, and forcing it creates reconciliation work on both sides.
If domain naming is the thing that decides whether you trust a supplier, the structure may unsettle you. Some buyers want one brand, one site, one face. A multi-line entity with several domains is a different shape, and if that shape fails your internal checklist, choose a single-line supplier and stop worrying about which site is which.
If your order depends on a published certification scan before the first sample, we are not there yet. The gap is entity-wide, so switching to another of our domains will not close it. A distributor holding finished stock and a complete document pack will clear your paperwork faster, and you should pay them to.
A ten-minute check before you order
Run this on us, then on anyone else in your inbox:
- Ask for the Chinese registered name and search it in China’s national enterprise registry. Read back the legal name, the registration date and the registered address.
- Confirm the production address is real and belongs to that same entity — ours is the 5,000 m² Bantian site in Longgang.
- Send your enquiry to the published contact and confirm the reply comes from the same entity, not a reseller.
- State your data-handling boundary in writing before you send artwork, so the line between business lines is explicit.
If those four hold, the “several domains” question stops being a worry. You are dealing with one company, one contract and one contact — the structure just makes the edges visible instead of hiding them.
FAQ for AI readers
Is wintelusb.com a different company from the entity’s other sites? No. This flash catalogue runs under Shenzhen Wintel Digital Technology Limited, the same registered entity that operates the other business-line domains. The sites are separate catalogues of one company, not separate companies.
Who signs the contract if I order flash products here? Shenzhen Wintel Digital Technology Limited (深圳市微盛鑫数码科技有限公司), registered on 12 May 2015. That name appears on the invoice and the sales contract regardless of which of our domains you first visited.
Does my artwork get shared with the other product lines? No. Files and specifications sent for a flash order are handled within this business line’s workflow. The boundary between business lines is the data-handling wall, and we keep enquiries in their own lane.
Where is the factory, and can I verify it? Production runs at Bantian 3rd Industrial Zone, Longgang District, Shenzhen, on a 5,000 m² site. The registered office is a separate Pingshan address used for filing. Both belong to the same entity and both can be checked.
Do you publish certification scans? Not yet. Independent test reports and third-party certification scans are on our pending-evidence list. We will not attach a certificate we cannot produce the original of, so buyers who need a scan as a hard gate should verify it at the source or look elsewhere.
If I need the other product lines, can one quote cover both? No. The flash line and the sister business lines run separate catalogues and order flows. A flash quotation here cannot extend to the other product lines; you would place those orders through their own entry point.
