I haven't get still on my hand

but I have received a steel item from Squirellbits few weeks ago.
Italy customs has not requested nothing...
Well, well... maybe here they are not "really focused" on that... the package was not inspected and so on... just asked customs fees...
BTW I have verified and it seems it's allowed importation even without MTC test: (see below - translated with google translated...)
However, it must be clear that, in the absence of this document, the operation can still be carried out provided, the authorities specify, the origin of the production factors has been attested with further and combined means of proof or a combination such as, for example, invoices , delivery notes, supplier's declarations, including multi-shipment supplier's declarations (long-term supplier's declarations), business correspondence, production descriptions, quality certificates and clauses in purchase orders or executed contracts, to provided that they include information on the origin of the production factors used.
