What the chamber certifies
A certificate of origin states where goods were made. It travels with a single shipment and names the exporter, the buyer, the marks on the cases and the quantity inside them. Customs officers abroad use it to work out duty. Because it belongs to one consignment, you cannot keep a spare in a drawer.
Getting the form from the Camera di Commercio
In Italy the certificate is issued by the Camera di Commercio on its own form. Genoa's chamber serves the firms around the port, so exporters here order it locally. How to legalize a Certificate of Origin begins at that counter, since the chamber's stamp is the mark every later desk checks.
Make it match the invoice
Bring the invoice and the packing list with your request. The description of the goods, the weights and the case marks must read the same on every sheet. A single mismatch between invoice and certificate is enough for the file to be stopped abroad. Read the three papers side by side before you file them.
The Prefettura stamp
The state's own stamp comes next. Consular legalization of a Certificate of Origin in Italy cannot start until the Prefettura has legalized the chamber signature. That office is the state's representative in the province, and it holds specimen signatures for the chamber officials. Judgments and notarial deeds go elsewhere, to the Procura della Repubblica.
The buyer's consulate in Italy
The buyer's own mission has the last say. The embassy legalization of a Certificate of Origin in Genoa is completed at that consulate in Italy, which adds a stamp of its own. Some missions want the invoice legalized alongside the certificate, so ask what the full bundle should hold before you book.
Duty, charge and the sailing date
Costs come in two parts — the €16 stamp duty here, plus the consular charge set by the receiving mission. Allow 10–15 business days from the day we get the papers, or 3–5 business days on the express route. Where the vessel has already sailed, most exporters legalize a Certificate of Origin in Genoa on the fast track.
When the consular link is needed
Whether the embassy attestation of a Certificate of Origin in Genoa is needed at all depends on the buyer's country, not on us. Some destinations release cargo on a single-step certification. Others hold it until their mission's stamp is on the paper. Put the question to the buyer or their customs broker in writing, and keep the reply with the file.
