How to spot a fake certificate of origin for DRC copper

Forged certificates of origin turn up in a large share of the cathode offers that circulate on WhatsApp and LinkedIn. Most of them are not clever. They fail on basic facts that anyone can check once they know how copper physically leaves the Congo.

This guide covers the checks we use first. None of them needs special software.

Rule of thumb: one truck, one set of papers. A single certificate covering hundreds of tonnes of cathode that left the DRC by road is the fastest fake to catch.

What a certificate of origin is for

A certificate of origin states where goods were produced. For Congolese copper it sits inside a larger export file that also includes customs declarations, mining and export authorisations, weighbridge tickets and border documents.

You don't need to memorise which office stamps which page. You need to ask one question: is this paper consistent with how copper actually moves?

The per-truck rule

Almost all cathode from the Katanga and Lualaba copperbelt leaves by road. A typical truck carries roughly 32 to 36 tonnes. The export paperwork follows the truck, so in our experience each truckload has its own documents, including its own certificate of origin.

That makes a single certificate for 100, 500 or 2,000 MT of cathode a strong warning sign. It looks like a document typed at a desk by someone who has never loaded a truck.

There is one point that confuses people. When many trucks arrive at a bonded warehouse in Dar es Salaam or Durban and the lot is shipped by sea, the bill of lading can cover the whole lot. The origin paperwork from the DRC side still traces back truck by truck. So ask for the truck-level file:

• truck and trailer registration numbers
• the date each truck crossed the border (for example at Kasumbalesa)
• the weighbridge ticket for each truck
• the certificate for each truck

A real exporter has these. Someone selling a template does not.

Kilograms, not "MT"

Congolese customs paperwork records weight in kilograms, for example "33 480 kg". A certificate that states "500 MT" or "96.000 MT" in the weight field has usually been edited, or built from a template made outside the DRC.

Dates that cannot be true

Read every date on the page, slowly:

• An issue date in the future. It happens more often than you would think.
• An issue date after the claimed shipment date, or long before the copper could have been produced.
• A US date format (month first, such as 07/22/2025) on a Congolese document. The DRC writes day first.
• An expiry date that equals the export date, or validity periods that make no sense.

Stamps, paper and handwriting

Forgers try hard to look official, and that is often what gives them away:

• many overlapping round stamps in random places, in different ink colours
• handwritten entries in fields that should be typed
• plain coloured paper photographed to look like security paper
• one line, often the company name, in a slightly different font, size or sharpness from the rest
• destination names that are not real places, or that are spelled the way no shipping line would spell them

Names that don't match

Lay the papers side by side: the certificate of origin, the sales offer (SCO or FCO), the warehouse receipt and the invoice. The exporter, the seller and the owner of the goods should be the same company, or the link between them should be explained in writing.

Also check that the exporter's licence is valid for the current year. Lapsed licences are common, and a lapsed licence means the copper cannot legally leave in that company's name.

How to confirm a certificate is real

1. Ask for the truck-level file described above. Real sellers send it within a day or two.
2. Contact the issuing office yourself, using contact details you found independently, not the phone number or email printed on the document.
3. Ask the warehouse that is said to hold the copper to confirm that it received those trucks, with dates and lot numbers. Again, use the warehouse's official contact details.
4. Run the document through a document check. It flags the patterns in this guide automatically and explains each one.

What even a real certificate won't tell you

A genuine certificate of origin proves where the copper came from. It does not prove that the person offering it owns the copper today, that the copper is still in the warehouse, or that it meets the grade on the offer. Pair it with warehouse confirmation and an independent inspection before you pay.
