We keep your COAs straight.
For brands that sell through other people's stores.
One link per product, printed once. Every batch keeps its own report. A person matches each report to the right product, size and batch, and tells you when one is missing. You forward the lab email. We do the rest.
A sample product with a watermarked sample document, so the flow can be clicked through. Real records resolve to the lab's document, never to values on this page.
How it usually goes.
The report goes in a folder. The page on your site gets a new row. The QR on the label points where it pointed last year. When a store asks for a file, someone goes and finds it.
Nobody checks that the file under a product is the file for that product. We found a wrong one on a real brand's page in September 2026. The brand did not know.
A new batch
You forward the lab's email, or the lab copies our inbox. Then:
- I.We match the report to the product, size and batch it names.
A person checks it. Folder links, viewer pages and partial files are rejected. If a match is unclear, we ask you.
- II.We put it behind the product's permanent link.
The one on your label. The link stays. The document changes.
- III.The older batch keeps its own link.
A can from last spring still finds last spring's report.
- IV.A product with no current report goes on a list.
You see the list. Nothing else.
We match, host and keep. We do not grade the results. The lab's document is the document. The whole flow
One record. Every place someone looks.
Your label
One QR or link per product. A new batch never means a new label.
Your site
A batch search box. One paste. Type the batch number, get that batch's report.
The store's product page
Stores paste the same link once. Free, no account. It stays current.
The public lookup
Barcode or batch number at rdrelay.com/lookup. No sign-in.
A folder stores files. That is all it does.
| A folder and a page you maintain | A lab portal or a COA plugin | rd Relay | |
|---|---|---|---|
| A new batch, without editing a page | No. You edit the page. | Only if you post each one. | Yes. |
| Older batches findable by batch number | Only if every file was kept and named right. | If you keep posting them. | Yes. Every batch keeps its own link. |
| Someone checks the file matches the product, size and batch | Nobody. | Nobody. | A person, every document. |
| Any lab, any platform | Yes. | One lab, or one platform. | Yes. |
| One label address that never changes | A folder, or one PDF forever. | A page. | One link per product. Printed once. |
| Who does the filing | You. | You. | We do. |

Brands on rd Relay"We run two stores and an online shop with more than fifty brands. I see whose documents are broken before they do, because a customer or an inspector asks me first. I built rd Relay so a brand can hand the filing to someone who checks it."
Recalls. Permits. History.
Three things the same record holds.
Recalls.
Flag a batch once. Its link stops serving the report and serves your notice instead, everywhere the link is. Every serve is logged. Try it on the sample.
Flag one barcode and its permanent link serves the recall notice instead of the document, on every page pointing at it.
Sample record — a demonstration.
Permits.
For stores and distributors. Every account's permits on one board with their expiry dates. Alerts from 60 days out.
The permit boardHistory.
Every publish, replacement and recall is logged with a timestamp. Exportable. What was current on a given date is on the record.
How the record is keptBuilt to be checked.
Your records are yours.
Each account reads its own rows and nobody else's. The database enforces it.
Every publisher is identified.
A brand's identity is checked before its records serve publicly. That is an identity check, not a judgment of the lab result.
Nothing of yours is trapped.
If rd Relay shut down: 90 days notice, a full export, and every link keeps serving through the notice period.
How to start.
Send your product list with barcodes and the COAs you have. In the first week we match everything, hand back one link per product and a list of what is missing. Then you forward each lab email. Setup, then a monthly fee sized to your catalog.
Prefer to run it yourself? Log in any time. You never need to.
