COMPANY 00 · INDEX
Two companies, one supply chain, and a boundary we keep visible.
The seller of record and the production entity are different companies. That is normal in this industry and it is usually hidden. Here it is on the first page, because a buyer's first question should be “who am I contracting with?”
The one-paragraph version
XinYonSen is the company that quotes, invoices and exports. Pufeng is the company that owns the tube mills, the forming lines, the galvanising relationship and the certificates. A buyer contracts with XinYonSen and the goods are produced by Pufeng; the mill and coating certificates come from the production side.
Why we do not blur it
A buyer who discovers the seller and the producer are different companies after the deposit starts wondering what else was not mentioned. Saying it first costs nothing and removes a whole category of doubt.
What can be verified, and how
| Claim | How a buyer checks it |
|---|---|
| Company registration | Business licence copy, name and number on the invoice |
| Production capability | Factory visit, or a video walk-through on request |
| Steel grade | Mill certificate per heat number |
| Coating | Coating certificate plus gauge readings at inspection |
| Project references | Named projects, with areas; site visits by arrangement |
| Certificates | Certificate register with expiry dates, copies on request |
Nothing on this page is a certification of compliance. It is a list of what exists and where the paper is.

Ask for the mill certificates, the packing photos or a video call on the line. We would rather answer those questions now than after the deposit.
