Import Permit Yes
Phytosanitary Certificate Yes
Additional Declaration/Endorsement No
Protocol Market No

Consignments are to be free from pests, soil, weed seeds and extraneous material.

A copy of the import permit must be presented to an Authorised Officer at the time of inspection.

Malaysian import permits may indicate that the following text be included as an additional declaration: "The issuance of this PC is based on the Malaysia IP reference number MAQXXXXXX."

  • Australian phytosanitary certificates cannot be issued with additional declarations that reference import permit numbers.
  • In negotiations with the Malaysian NPPO, it has been agreed that the import permit number indicated in the import permit section of Australian phytosanitary certificates is sufficient for meeting this requirement.
  • No text stating the import permit number in either the additional declaration section or the additional product description section is required for clearance, regardless of the statement on Malaysian import permits regarding import permit number printing requirements.

If required by the import permit, consignments must be:

Fumigated with Methyl bromide at 48 grm/m3 for 24 hours, or more, at a minimum temperature of 21 degrees Celsius;

OR

Fumigated with phosphine at 4 grm/m3 for 120 hours at a minimum temperature of 21 degrees Celsius;

OR

Heat treated for 4 hours, or more, at a minimum core temperature of 70 degrees Celsius (continuous).

Treatment must be undertaken no more than 14 days prior to export.

Please note that the department's minor use permit for aluminium phosphide and cylinderised phosphine gas (both 99% phosphine and 2% phosphine active constituent versions) only allows for above-label concentrations if fumigation is conducted over a minimum exposure period of:

  • 7 days when commodity temperature is above 25 degrees Celsius
  • 10 days when commodity temperature is 15-25 degrees Celsius
  • 20 days for surface-only applications in well-sealed structures greater than 375m3 (300 metric tonne capacity)—it is the fumigator's responsibility to apply as appropriate.
Although the minimum fumigation duration and/or temperature required by the NPPO is below this, the department's minor use permit does not allow for treatments shorter than the above periods or at lower temperatures. The phosphine concentration applied must still meet the NPPO minimum concentration.

Treatment requirements with minimum concentrations greater than the below schedules are considered above-label treatments:

FumigantConcentration
Aluminium phosphide1.5 grm/m3
99% phosphine gas1.4 grm/m3
2% phosphine gas70 grm/m3 (1.4 grm/m3 phosphine)
(Magnesium phosphide)(No departmental minor use permit available)
 

Treatment details for phosphine treatments are to be endorsed in the Treatment section as:

“WITH [PHOSPHINE/ALUMINIUM PHOSPHIDE] AT [NPPO concentration]GRM/M3 FOR [NPPO minimum duration] OR MORE AT [temperature] DEGREES CELSIUS [add “OR ABOVE" if fumigation temperature is greater than NPPO minimum temperature]"

For example, if an NPPO requires aluminium phosphide  treatment at 5 GRM/M3 FOR 5 DAYS at 20 DEGREES CELSIUS, the treatment should be conducted at 5 grams per cubic metre for 10 days at 20 degrees and the text should read as:

“WITH ALUMINIUM PHOSPHIDE AT 5 GRM/M3 FOR 5 DAYS OR MORE AT 20 DEGREES CELSIUS"


The exporter is to provide evidence attesting to the treatment and present it to the Authorised Officer at the time of inspection.

Details of treatment to be endorsed on the phytosanitary certificate in the treatment section.
