How do I submit samples?

Each sample must be marked with the same name on the packaging as on the sample form. The sample should be well-sealed, for example in a closable plastic bag or test tube. Note that the sample form and the packaging with the sample must not be attached onto each other, and the sample should not be packaged in aluminium foil.

You can send your sample as a letter or as a parcel, depending on the size of the sample. Addresses can be found on the sample form and below.
