EAN Data
Open barcode data for Denmark.
A barcode is the one thing a product carries that a machine can read with certainty. If you know what a number means, software can help someone decide what to do with the item in front of them. That lookup does not exist as open data for the Danish market, so we are building it.
What we publish
ean-product-dataset — barcode to product name, description, product image, retailer and safety data sheet link, harvested from public product pages at Danish retailers.
| Products | 1,132,080 |
| Retailers | 153 |
| With a fetched image | 909,774 |
| With a safety data sheet link | 31,773 |
| Assessed as chemical products | 56,461 |
How we work
Images are stored as original bytes, not as links. A URL is a promise: a retailer can change CDN tomorrow, and the dataset would be empty without looking empty. Every image is kept byte for byte as the retailer sent it — same format, same resolution. Re-encoding and downscaling are both irreversible, and a downscaled JPEG is too little if a model is later to read the label text.
Every barcode is verified with its check digit, and only counted when the page itself labels it as an EAN, GTIN or barcode. A loose 13-digit number is just as often a phone number or a form placeholder.
"Not assessed" is not "not hazardous". is_chemical is true, false
or null, and null means nobody has looked yet. Filtering that distinction
away would be a claim we cannot support.
Stock photos are labelled, not removed. When the same image file appears on 25 or more different items, it is the shop's "image to follow" icon rather than a product photo — we mark it and leave it in. A silent filter is a claim nobody can check.
Why
The dataset grew out of work on chemical waste sorting: staff at Danish recycling centres photograph a product and are told which container it belongs in. Getting that right needs to know what the barcode is, and the lookup turned out to be the hard part. It seemed more useful shared than kept.
Provenance and rights
Content was fetched from retailers' public product pages; every row records
its source, product_url and harvested_at.
Product names, descriptions and photographs remain the property of the respective retailers and manufacturers. We claim no rights over them and publish the data as-is, for research and for building tools that help people sort chemical waste correctly. If you are a rights holder and want a row or an image removed, open a discussion on the dataset and it will be removed.
