Selling FRM - Master Certificates
This document sets out information relevant to each specific collection of FRM, such as quantity, species, provenance and origin.  Each certificate is given a unique number that identifies that collection which must refer to a single entry in the National Register of Basic Material.  The Master Certificate number allows the Forestry Commission to trace the FRM from collection to planting. The suppliers who applied for them must keep Master Certificates for minimum period of 5 years.

  • How to get a Master Certificate
    Complete one or more of the following forms: 
    • FRM4A  Seed sources and stands
    • FRM4B  Seed orchards or parents of family
    • FRM4C  Clones and clonal mixtures 

  • When to apply for a Master Certificate
    The supplier must apply to the Forestry Commission for a Master Certificate within 9 months of collection of, or before marketing, the FRM, whichever is earlier.

Selling FRM - Suppliers Documents
Each time seed or plants grown from material covered by a Master Certificate are marketed; a Suppliers Document must be given to the buyer at the time of delivery. 

The Suppliers Document gives the following information:

  • All the information required by the Master Certificate
  • Quantity of FRM supplied
  • Name of the supplier
  • Master Certificate Number
  • Additional information as required

Suppliers Documents must be issued whenever marketing takes place at any stage in the production of planting stock for a single collection, not just when the original collector markets material.

Whenever seed is marketed, a Seed Test Certificate must also be copied to the recipient.  Seed testing is carried out by approved seed testers.
