Prior to issue of a phytosanitory certificate for export of plant and plant products, the material should be inspected and tested to ascertain the pest freedom for some quarantine pests. Therefore the exporter should make a request from Additional Director ,NPQS specifying the conditions stipulated by the importing country. Upon receipt of such request plant quarantine operations division carry out following activities.

Registration of request
Investigate the request and inform the relevant officers (Entomology/Pathology/Treatment Technology/ Weed Science) for nursery or factory inspection.
Coordinate the nursery/factory inspection & sampling considering the additional declarations and the date of dispatch of the consignment.
Preparation of format for test report and distribute among the relevant laboratories.
Collection of test report prior to date of export and inform contaminants of to the exporter.
Preparation of final test report and send to exit point to issue phytosanitory certificate prior to date of dispatch.
International agreement is that only authorized officers of the official plant protection service  shall issue the phytosanitory certificate for all plant commodities exported.
Phytosanitary certificates are prepared according to the model given by IPPC.
A PSC is issued in three copies in English only. The original and a copy are kept in office and a copy is given to the applicant.
Two different formats are available as Phytosanitory certificate and phytosanitory certificate for re export.


Plant nurseries/factories inspection, registration and accreditation
The companies who wish to export plants or plant products have to be registered with the NPQS Further as an import requirement, some Importing countries require the nurseries/ production sites to be accredited.
The Plant Quarantine Operations Division is responsible for these activities.

Due to insufficient certifications, inaccurate declarations, non fulfillment of specific entry conditions and visible pest infestation, plant quarantine officers at entry points can not release the consignment. Under such conditions plant quarantine officers of the entry points seek advice/ further testing from the NPQS. Normally plant quarantine officers of the seaport/airport do sampling and send to NPQS / operation division with a form of submission of intercepted materials.

Testing intercepted material
1. Sample submitted from entry ports to the Plant Quarantine Operations Division
2. Registration of intercepted sample with following information.

              a. Date received
              b. Name and address of the importer
              c. Name of the importing country
              d. Permit number and date
              e. PSC number and date
              f. Material and quantity

3. Based on the reason for interception, samples of the material are distributed to relevant technical laboratories for further testing.    

4. Printing and distribution of report format to relevant technical laboratories (entomology/pathology/weed science/treatment technology) to submit the test results.

5. Compiling final test reports and final decision to the release of consignment is taking by the Additional Director, National Plant Quarantine Service, Katunayake. Apart from that questionable material carried by the air travelers are detained at the port of entries and send to Additional Director/ NPQS for destruction.
All items prohibited to import to Sri Lanka are liable to confiscation and destruction.  These consignments are destroyed in a manner that is technically justified to be eliminating the associated pest risk under the supervision of the officers of the plant quarantine operation division. The details of the consignments which are subject to destruction are recorded in a separate register.
