The most useful page on your site may be one that only exists after the sale.
ESPR, the EU regulation behind digital product passports, has been in force since July 2024, with apparel requirements expected around 2027. Most brands have filed it as a compliance line item for a future budget cycle. Nobody's Child, a UK brand at roughly 30M in revenue, already ships garments with QR passports and published its playbook while luxury houses were still scoping theirs.
A passport is a per-unit record, not a per-SKU one. Scan the tag and you get this garment: what it is made of, where it was made, how to wash it, how to repair it, what it is worth on resale today, and a one-tap path to list it or reorder it. On Shopify that is a metaobject per unit, a QR code or NFC chip in the label, and a landing page that gains content as the product ages.
The strategic part is that it survives resale. When the second owner scans the tag, they land on your page rather than a marketplace listing. You learn that the item resold, roughly what it fetched, and that a new person now owns it. For most brands that is the only reliable window they will ever get into a secondary market they already supply for free.
The catch is per-unit data discipline. Serializing at unit level means your factory, your labels, and your warehouse all carry an identifier that never breaks, and most apparel supply chains were not built for that. Expect real negotiation with vendors, a per-garment tag cost, and a scan experience that has to work on a 4-year-old phone in a changing room. The regulatory target is still moving, so build a data model you can extend rather than chasing a final spec that does not exist yet. Treat the compliance reading as a job for counsel, not for a project manager with a PDF.
Every product you have ever sold is still out there, still being worn, still saying nothing. That silence is a choice you keep making.
