5 Documents Every Import Buyer Should Request Before Signing a Supply Contract

Most import buyers request one or two documents before signing a supply agreement. Here is the full stack — what each document is, why it matters at customs, and what a gap in any one of them can cost you.

1. Phytosanitary Certificate

Issued by the national plant protection organisation of the exporting country, this certifies that the produce has been inspected and is free from pests and diseases. Without a valid, shipment-specific phytosanitary certificate, agricultural products will be held at customs on arrival in the UK or EU — regardless of any other documentation.

2. EU Export Certificate / UK Import Licence

For animal-origin products entering the EU or UK, an official health certificate signed by the exporting country's competent authority is mandatory. For plant-origin products, EU import requirements vary by product and origin but often include additional documentary checks. Verify which applies to your specific product and origin before contracting.

3. HACCP Compliance Records

Hazard Analysis and Critical Control Points documentation confirms that the processing facility operates to food safety standards. Retail buyers — particularly UK supermarket category managers — will request this during supplier onboarding. A supplier without current HACCP records is unlikely to pass a retail buyer audit, regardless of product quality.

4. GlobalG.A.P. Certificate

The leading global standard for good agricultural practices. Increasingly required by UK and EU supermarkets as a baseline supplier qualification. Without it, a producer cannot be listed as a direct supplier to major retail chains — making it a minimum threshold for retail-grade supply, not an optional credential.

5. Country of Origin Declaration

Required for tariff purposes under both UK Global Tariff and EU Common External Tariff. With UK CBAM now in force, the origin declaration also links to carbon content reporting requirements. An inaccurate origin declaration exposes both importer and exporter to customs penalties.
