A supplier marked hidden, or hidden by the account-wide setting, is now also hidden under Materials on the public passport — so supplier confidentiality holds consistently across the whole passport.
When hidden, the material shows no supplier. Name, description, composition, origin, colour and certificates are unaffected.
Staff and distributor accounts see the supplier, the same as in Traceability. This adds no new setting; it reuses the existing per-supplier flag and account toggle.
If you already use hidden suppliers or have the account-wide toggle on, a supplier name that used to appear under Materials will no longer show. No action is needed on your side.
