ANNEXES


I. Approved measures associated with wood packaging material

Heat treatment (HT)

Wood packaging material should be heated in accordance with a specific time-temperature schedule that achieves a minimum wood core temperature of 56oC for a minimum of 30 minutes[3].

Kiln-drying (KD), chemical pressure impregnation (CPI), or other treatments may be considered HT treatments to the extent that these meet the HT specifications. For example, CPI may meet the HT specification through the use of steam, hot water, or dry heat.

Heat treatment is indicated by the mark HT. (see Annex II)

Methyl bromide (MB) fumigation for wood packaging material

The wood packaging material should be fumigated with methyl bromide. The treatment is indicated by the mark MB. The minimum standard for methyl bromide fumigation treatment for wood packaging material is as follows:

Temperature

Dosage rate

Minimum concentration (g/m3) at:

0.5hrs.

2hrs.

4hrs.

16hrs.

21oC or above

48

36

24

17

14

16oC or above

56

42

28

20

17

11oC or above

64

48

32

22

19

The minimum temperature should not be less than 100C and the minimum exposure time should be 16 hours[4].

List of most significant pests targeted by HT and MB

Members of the following pest groups associated with wood packaging material are practically eliminated by HT and MB treatment in accordance with the specifications listed above:

Pest group

Insects


Anobiidae


Bostrichidae


Buprestidae


Cerambycidae


Curculionidae


Isoptera


Lyctidae (with some exceptions for HT)


Oedemeridae


Scolytidae


Siricidae

Nematodes


Bursaphelenchus xylophilus

II. Marking for approved measures

The mark shown below is to certify that the wood packaging material that bears the mark has been subjected to an approved measure.

The mark should at minimum include the:

- symbol

- ISO two letter country code followed by a unique number assigned by the NPPO to the producer of the wood packaging material, who is responsible for ensuring appropriate wood is used and properly marked

- IPPC abbreviation according to Annex I for the approved measure used (e.g. HT, MB).

NPPOs, producers or suppliers may at their discretion add control numbers or other information used for identifying specific lots. Where debarking is required the letters DB should be added to the abbreviation of the approved measure. Other information may also be included provided it is not confusing, misleading, or deceptive.

Markings should be:

- according to the model shown here
- legible
- permanent and not transferable
- placed in a visible location, preferably on at least two opposite sides of the article being certified.

The use of red or orange should be avoided since these colors are used in the labeling of dangerous goods.

Recycled, remanufactured or repaired wood packaging material should be re-certified and re-marked. All components of such material should have been treated.

Shippers should be encouraged to use appropriately marked wood for dunnage.

III. Measures being considered for approval under this standard

Treatments[5] being considered and which may be approved when appropriate data becomes available, include but are not limited to:

Fumigation
Phosphine
Sulfuryl fluoride
Carbonyl sulphide

CPI
High-pressure/vacuum process
Double vacuum process
Hot and cold open tank process
Sap displacement method

Irradiation
Gamma radiation
X-rays
Microwaves
Infra red
Electron beam treatment

Controlled atmosphere

[3] A minimum core temperature of 56° C for a minimum of 30 min. is chosen in consideration of the wide range of pests for which this combination is documented to be lethal and a commercially feasible treatment. Although it is recognized that some pests are known to have a higher thermal tolerance, quarantine pests in this category are managed by NPPOs on a case by case basis.
[4] Certain countries require that the minimum commodity temp should be higher
[5] Certain treatments such as phosphine fumigation and some CPI treatments are generally believed to be very effective but at present lack experimental data concerning efficacy which would allow them to be approved measures. This present lack of data is specifically in relation to the elimination of raw wood pests present at the time of application of the treatment.
