The sampler must:

  1. initiate sampling as soon as possible after receiving a service request from the establishment;
  2. for pedigreed seed, assign the lot number as derived from the Seed Inspection Certificate and provide the lot number to the establishment. At the time of sampling, leave a copy of the certificate with the establishment;
  3. communicate with the operator, grower, owner/manager of the establishment to determine the number of seed lots to be sampled and their location in the warehouse;
  4. obtain from the establishment operator the required documents (i.e., crop certificates, pedigreed seed declaration, blend sheets, Application for Seed Analysis, extra tags) to enable sampling to proceed;
  5. verify that the seed lot is accessible;
  6. verify that all containers are labelled with kind, variety if applicable, and lot identifier/ number;
  7. verify that there is no evidence that the lot has been tampered with;
  8. verify that all portions of the lot are packaged in the same size and type of container;
  9. when tags are affixed to a seed lot, verify that the information on the tag corresponds to all the documentation. If the back of the OECD tags indicates a month and year of sealing, the sampler must verify that date of sampling does not precede the labelled date of sealing;
  10. when the seed lot is tagged with OECD tags, the tag must contain all the information as required by QSP 152.1 Implementation of the OECD Seed Schemes and EU Seed Directives. Otherwise, refuse to sample the seed lot;
  11. verify that the seed lot size does not exceed the maximum lot sizes as stated in the ISTA International Rules for Seed Testing Chapter 2;
  12. for the issuance of an Orange International Seed Lot Certificate, where the company prints the official tags prior to sampling, verify that all information printed on the tags is correct on every container;
  13. for seed lots of non-pedigreed seed, the company must mark or label each container in the seed lot with a unique lot designation/number. The sampler's responsibility is to verify that all the operations are conducted in accordance with ISTA Rules;
  14. verify that all seed is sealed in tamper-proof containers. Containers of non-pedigreed seed must also be sealed with a CFIA metal seed seal, by the sampler or under the direction of the sampler;
  15. select the appropriate approved sampling method based on the packaging of the seed and crop kind as specified in Appendix I;
  16. prior to sampling, clean sampling triers and equipment thoroughly and verify that the adjacent area surrounding the seed lot is free of foreign/contaminating material;
  17. sample according to the sampling intensities specified in Appendix II;
  18. sample the seed lot using the appropriate technique for the selected trier or method as described in Section 7;
  19. not insert triers through labels or printed labelling on the container
  20. close the holes in jute or poly bags made by the trier by running the point of the trier across the hole a couple of times in opposite directions to pull the threads together to close the holes. When the holes cannot be closed by this method, suitable adhesive patching tape/labels must be used. The patch should be signed and dated by the sampler;
  21. verify that all primary samples drawn from containers or bulk are of approximately equal amounts of seed and each primary sample must be checked for uniformity as to seed lot homogeneity described in Section 10.0;
  22. clean the container/pail in which the sample is placed as it is drawn thoroughly at the beginning of the sampling procedure and after each sampling operation;
  23. verify that uniform primary samples are combined to form the composite sample. The composite sample is submitted to the laboratory (submitted sample) except, in some cases, the composite sample of the large seeded crop kinds may be mixed and divided as described in Section 13.1;
  24. verify that the submitted sample is labelled, (including the tag used in tagging the seed lot sampled) sealed, and packaged securely for shipment to the laboratory as soon as is practicable as described in Section 15;
  25. draw moisture samples as described in Section
