NOTE:
To be able to export logs to China, registered establishments must be on a list approved by the General Administration of Customs of the People's Republic of China (GACC). Registered establishments, fumigators and Authorised Officers must also be audited and approved by the Grain and Seed Export Program prior to any export of logs to China. Please contact the Grain and Seed Exports Program (Grain.Export@aff.gov.au) to be listed by GACC and for more information regarding the registration application and audit for exporting logs to China.
Consignments are to be free from pests, soil, weed seeds and extraneous material.This Micor case applies to all logs for export to China, as well as the following sandalwood (Santalum album) products:
- sandalwood logs (with or without bark)
- sandalwood roots
- sandalwood discs
- sandalwood blocks
- sandalwood sticks
- any other sandalwood products which may include bark.
Please note the below.
- Logs without an accompanying phytosanitary certificate, and/or logs with bark that have not gone through quarantine treatment, will not be permitted entry into China.
- Inspection of logs for export to China must be done at a registered establishment approved by the Grain and Seed Exports Program for inspecting logs for export to China.
- Inspection of logs for export to China must be done by an authorised officer approved by the Grain and Seed Exports Program for inspecting logs for export to China.
- Fumigation of logs must only be performed by a fumigator approved by the Grain and Seed Exports Program for fumigating logs for export to China.
Fumigation must take place at either a registered establishment approved by the Grain and Seed Exports Program for fumigating logs for export to China or in a bulk vessel hold - fumigation in bulk vessel holds require a fumigation plan sent to the Grain and Seed Exports Program; please refer to details in the Treatment section.
The registered establishment number and fumigator licence number(s) of all fumigators involved must be entered for all consignments of logs with bark in the additional product description of the Request for Permit (RFP) as follows:
- "[full botanical name (genus and species)] inspected and packed at establishment [establishment number], fumigated by fumigator(s) [fumigator 1 licence number], [(if applicable) fumigator 2 licence number], [etc.]"
The establishment number listed in this statement must be the establishment listed in the RFP. The fumigator licence number(s) must be present on the fumigation certificate and must match.
Consignments of logs without bark that have not been fumigated must still report the registered establishment number as below:
- "[full botanical name (genus and species)] inspected and packed at establishment [establishment number]"
The establishment number listed in this statement must be the establishment listed in the RFP.
Contact the Grain and Seed Export Program (Grain.Export@aff.gov.au) for more details in relation to:
- Inspection of the container prior to loading
- Inspection of the logs prior to loading
- Mandatory treatment of logs with bark (pre-shipment)
- Inspection of logs after treatment
- Phytosanitary certification
All logs with bark require mandatory treatment prior to shipment using one of the below treatment methods.
If logs without bark fail their initial inspection, they are also subject to one of the below treatment methods.
Fumigators are to ensure that all fumigation enclosures are sufficiently gas-tight to retain the required concentration for the duration of the exposure period. If gas concentrations during monitoring are found to be below the target values shown in Table 1, gas must be topped up to ensure the concentrations at any time during the exposure period do not fall below the target value. The monitoring and topped up details must be recorded on the fumigation certificate.
If logs without bark fail their initial inspection, they are also subject to one of the below treatment methods.
Fumigation of logs must only be performed by a fumigator approved by the Grain and Seed Exports Program for fumigating logs for export to China. Below is a list of approved fumigators - note this is only a list of fumigators who have consented to have their details published, not a complete list. It is the exporter's responsibility to ensure fumigators are approved for treating logs to China. Please contact Grain.Export@aff.gov.au to verify whether a specific fumigator is approved for treating logs for export to China.
Note: Fumigators can only fumigate at establishments that they are specifically approved for. Please contact Grain.Export@aff.gov.au if you need to verify whether a fumigator can perform fumigations at a specific establishment.
The fumigation event must take place at either a registered establishment approved by the Grain and Seed Exports Program for fumigating logs for export to China or in a bulk vessel hold - fumigation in bulk vessel holds require a fumigation plan sent to the Grain and Seed Exports Program, details further below.
Methyl Bromide fumigation at:
- 80grm/m3 for a minimum of 24 hours at above 15 degrees Celsius;
OR
- 120grm/m3 for a minimum of 24 hours at between 10-15 degrees Celsius.
Note: The lowest measured log temperature is used to calculate the fumigation dosage, not the forecast minimum ambient temperature (or enclosure temperature if heaters are used). If the forecast minimum ambient temperature is lower than 10 degrees Celsius, heaters must be used to raise the air temperature to at least 10 degrees Celsius, verified with an enclosure temperature reading, and this information must be endorsed on the fumigation certificate.
Gas concentrations must be monitored and recorded at the start of fumigation, at 2 hours, 16 hours and 24 hours (end of fumigation) (as shown in Table 1) after equilibrium has been achieved to assure that the minimum concentration of methyl bromide is maintained as per "Methyl bromide fumigation methodology, 1 May 2025, Version 3" (https://www.agriculture.gov.au/sites/default/files/documents/methyl-bromide-fumigation-methodology-v3.0.pdf).

Each fumigation chamber/enclosure must have a minimum of three monitoring lines at the bottom, middle and top of the stack away from the gas injection point. For sheet fumigation, logs must be stacked on a sealed surface and covered with gas proof sheets.
NOTE:
- Equilibrium is established when the highest concentration reading is within 15% of the lowest concentration reading.
- Equilibrium can be calculated as: (Highest Reading - Lowest Reading) x 100/Lowest Readings ≤ 15
OR
Sulfuryl Fluoride fumigation at:
- 104grm/m3 for a minimum of 24 hours at between 5-10 degrees Celsius;
OR
- 80grm/m3 for a minimum of 24 hours at above 10 degrees Celsius;
OR
- At recommended manufacturers requirements (registered label rates).
Gas concentrations of sulfuryl fluoride must be monitored at 2 hours, 16 hours and 24 hours after equilibrium has achieved to assure that the minimum concentration of methyl bromide (Table 2) is maintained as per ISPM 15 requirements.
