Multi-region, US ADA codes vs EU CE-mark vs AU TGA registration, multi-store with shared SKUs?

Yes, Magento native multi-store handles this cleanly. The regulatory metadata lives on the product, not the storefront, so one SKU renders regulator-correct per region.

• US, ADA Code on Dental Procedures and Nomenclature (CDT codes) for billing tie-in to clinics’ practice-management systems. FDA UDI per device. NDC code if you carry any Rx items.
• EU, CE-mark with class (Class I, IIa, IIb, III) per device, EU MDR 2017/745 since May 2021. Notified Body number for Class IIa+. Eudamed registration (the EU equivalent of GUDID). Distance-selling rules + 14-day right-of-return (less relevant for B2B clinics, mandatory for any DTC).
• AU, TGA (Therapeutic Goods Administration) registration with ARTG number per device. Sponsor liability sits with the importer.
• CA, Health Canada MDL (Medical Device Licence) per device, class-graded similarly to FDA.
• UK (post-Brexit), UKCA marking, MHRA registration. Northern Ireland still uses CE.

Magento implementation: store views per region (en-US, en-GB, en-AU, en-CA, de-DE, fr-FR, nl-NL). Per-region product attributes (CE-mark class, ARTG number, MDL number, NDC code) populated per SKU. The PDP template conditionally renders the region-specific compliance block. The catalog is shared; the regulatory presentation is region-specific.

Practical: most US distributors don’t need multi-region day 1. Adding EU or AU later is a 4-6 week project once the base store is live. Decide multi-region scope before catalog ingestion to avoid re-shaping the attribute schema later.
