What the paper covers
A certificate of origin states where the goods in one shipment were made. Buyers use it to claim a duty rate, banks use it to release money under a letter of credit, and customs officers use it to decide what to charge. Knowing how to apostille a Certificate of Origin is part of exporting to any country that wants Italian papers proved.
The apostille itself is one certificate added by an Italian office, confirming that the seal and signature on your trade paper are genuine. It makes no claim about the goods. To apostille a Certificate of Origin in Bari, therefore, the paper must already be signed and sealed by whoever issued it.
Which office stamps trade papers
Trade papers are issued by public bodies, which puts them on the administrative side, and administrative papers are stamped by the Prefettura (Prefecture). You apostille a Certificate of Origin in Italy at the Prefettura of the province where the issuing body sits. If a notaio has instead sworn an exporter's own declaration, that act belongs to the Procura della Repubblica.
Cost, and the shipping clock
The apostille cost for a Certificate of Origin in Bari is a public charge: a €16 tax stamp per document, and some papers are exempt. Every paper in the set is counted on its own, so a shipment with three stamped papers means three charges. The clock, not the cost, is what hurts an exporter, so build the errand into your booking plan.
Buyers, banks and brokers
Demands are worded loosely. One buyer asks for a legalised paper, another for the legalisation of a Certificate of Origin in Bari, and a third simply says the file must be stamped. Italy has been inside the Hague Convention since 1978, so an apostille answers the request for other member states. Some destinations ask for a consular route instead, so check first.
Language and matching details
Where a broker works in another language, have a sworn translation made by a translator who signs an asseverazione, a formal statement of accuracy, before an Italian court. Keep the numbers on the translation identical to the original, and keep the whole set together: certificate, stamp, translation and invoice reach the far desk as one file.
