Where it comes from
A supply base is a set of places.
Silk in Como, worsted in Biella, recycled wool in Prato, knit in Porto, organic cotton in İzmir and Tirupur, selvedge in Osaka, alpaca in Lima. Tier 1 is a name on an invoice; tier 2 and tier 3 are a map - and the question that actually decides a season is which of these places can make your fabric, to which certification, at your volume.
Lodet AI searches mills, factories, biomaterial pioneers and certified suppliers across these regions, verifies GOTS, GRS, OEKO-TEX and Bluesign claims against the issuing body, and returns a dossier you can send — with the certificate numbers and the expiry dates in it.
