A container of food product can sit at the port in Lagos, Abidjan or Dakar for reasons that have nothing to do with tariffs or a missing invoice. It sits there because the health certificate attached to the shipment does not say what the importer’s licence says it should say. For manufacturers used to generating their own paperwork in-house, this is often the first export document that isn’t theirs to write: it depends on a third-party authority, it takes time to obtain, and getting it wrong stops the shipment cold at the point of entry, not before it leaves the factory.
What a health certificate actually confirms
A health certificate, sometimes called a sanitary certificate, is an official statement issued by a competent authority in the exporting country confirming that a specific consignment meets the food safety requirements of the destination market. It is not a general statement about the manufacturer’s standards; it applies to a defined batch, on a defined date, tied to a specific shipment. This is why the batch or lot numbers on the certificate have to match the packing list and commercial invoice exactly. It also works differently to a certificate of origin, which confirms where the goods were made, not whether they are fit for consumption.
Who issues it, and why it isn’t automatic
In Spain, health certificates for most foodstuffs are issued by Sanidad Exterior, the external health service under the health ministry, on request and based on documentation the manufacturer supplies: product formulation, analysis results, HACCP records. For products of animal origin, the certificate typically follows an EU export health certificate model, processed with input from the regional veterinary authority, often through the EU’s TRACES system.
None of this happens instantly, and the authority is not rubber-stamping a request. It is assessing evidence the exporter provides. Manufacturers who leave the application until the container is already booked routinely find themselves paying for a delayed sailing, or shipping without the certificate and hoping to send it on afterwards, which most buyers will not accept.
Health certificate versus certificate of free sale
Import permits and buyers do not always ask for the same document, and the terms get used loosely. A certificate of free sale confirms that a product is legally sold in its country of origin. It says nothing about whether that product meets the destination country’s specific food safety requirements, which is what a health certificate is for. Some import permits ask for one, some ask for both, and assuming they are interchangeable is a common way to end up with the wrong paperwork at the wrong moment. The only reliable approach is to ask the buyer, or read the import permit itself, for the exact wording required, rather than guessing from a template used on a previous shipment to a different country.
Where it goes wrong in practice
The failures that hold cargo at customs are rarely dramatic. They are small mismatches that a customs officer or port health inspector is trained to catch:
- The certificate uses generic wording that doesn’t match the product description or HS code declared on the commercial invoice
- The certificate is dated after the vessel has already sailed, breaching the validity window the destination market requires
- Batch or lot numbers on the certificate don’t reconcile with the packing list
- The destination country requires the product or its label to be pre-registered with its own national food authority, a separate and often lengthy process that no health certificate can substitute for
- The certificate hasn’t been legalised or authenticated in the way the buyer’s country requires, when that step applies
The registration point is the one manufacturers most often miss, because it sits outside the shipping process entirely. Several West African markets require food products, and sometimes their labels specifically, to be registered with a national food and drugs authority before import is permitted at all. A perfectly valid health certificate does not help if the product itself was never registered.
Before you apply, not after
A health certificate sits alongside, not instead of, other checks a buyer may require. Some contracts also call for a pre-shipment inspection, which examines the goods themselves rather than the paperwork describing them; the two serve different purposes and neither substitutes for the other.
Before finalising a shipping schedule, it is worth working through this in order:
- Ask the buyer, or check the import permit, for the exact certificate wording and validity period required
- Confirm whether the product or label needs prior registration with the destination market’s food authority, and how long that takes
- Apply for the health certificate early enough that the issuing date falls comfortably within the shipment’s transit window
- Check that batch numbers on the certificate match the commercial invoice and packing list before the container is sealed
None of this is complicated once it’s been done once. The manufacturers who get caught out are almost always shipping to a given market for the first time, treating the health certificate as a formality rather than a document with its own lead time and its own failure points.
