New Zealand WPM Requirements

IMPORTANT NOTE: A phytosanitary certificate is not required nor authorized for wood packing material when used as packing. Treatment is not mandatory but shipments arriving in New Zealand without treatment are subject to inspection.

Requirements:

• Must be free from pests that New Zealand has identified as being associated with wood packing material.
• Must not contain or be contaminated with greater than 0.01% by weight with extraneous material (e.g. leaves, soil, etc.).
• Must be bark-free: wood from which all bark excluding vascular cambium,ingrown bark around knots, and bark pockets between rings of annual growth has been removed.

 

Treatment Certificate Requirements

All certifications must be original, free of alterations and erasures, and printed in English. Treatment Certificates must contain the following information:

• A full description of the consignment and wood component
• All relevant identification marks and brands
• The number and/or volume of items treated
• The container number (where applicable)

 

Treatment Options

• Fumigate with methyl bromide or sulphuryl fluoride at 80 g/m3 for 24 hours at a minimum temperature of 10 degrees Celcius.

 

Wood packing material must be treated NO more than twenty-one (21) days before export to New Zealand .
Statement on Treatment Certificate that:,

"The wood packaging material has been fumigated with (insert methyl bromide or sulphuryl fluoride) at (insert fumigant concentration (g/m3)) for (insert duration of treatment) at a minimum temperature of (insert minimum temperature during treatment) on the (insert date of treatment (dd/mm/yy))."OR,

• Fumigate with phosphine at 1.41 g/m3 minimum atmospheric concentration for more than 72 hours, at a minimum temperature of 10 degrees Celcium and a maximum temperature of 30 degrees C.

 

Wood packing material must be treated NO more than twenty-one (21) days before export to New Zealand .

IMPORTANT NOTE: phosphine fumigation may only be used on wood packing material no thicker that 50mm and having a moisture content of less than 25%.

 

Statement on Treatment Certificate that,

"The wood packaging material has been fumigated with phosphine at (insert minimum atmospheric concentration (g/m3)) for (insert duration of treatment) at a minimum temperature of (insert minimum temperature during treatment) and a maximum temperature of (insert maximum temperature during treatment) on the (insert date of treatment (dd/mm/yy))." OR,

• Heat Treat at a minimum core temperature of 70 degrees Centigrade for more than 4 hours.

 

Wood packing material must be treated NO more than twenty-one (21) days before export to New Zealand .

Statement on Treatment Certificate that,

"The wood packaging material has been heated for (insert duration of treatment) at a minimum core temperature of (insert minimum core temperature during treatment) on the (insert date of treatment (dd/mm/yy))." OR,

• Chemical preservation to full sapwood penetration as specified in the following table:

 

Chemical	Minimum Retention
Boron compounds	0.1% Boric Acid equivalent minimum loading in the sapwood core
Copper + didecyldimethyl ammonium chloride (Ddac)	0.35% mass/mass OR 2.8 kg/m3 in softwood timbers, 5.60 kg/m3 in hardwood timbers.
Copper azole	0.27% mass/mass OR 1.35 kg/m3 in softwood timbers, 2.7 kg/m3 in hardwood timbers.
Copper Chrome Arsenic (CCA)	0.27% mass/mass OR 3kg/m3 minimum preservative retention
Arsenic	0.04% minimum preservation loading in sapwood core
Permethrin	Minimum retention of not less than 0.06% mass/mass

• No additional statements are required.

 

OR,

• Treat and label according to the requirements of the International Standards on Phytosanitary Measures (ISPM) 15. For additional information on " ISPM 15 refer to: Guidelines for regulating wood packaging in international trade" Refer to: https://www.ippc.int/static/media/files/publication/en/2017/05/ISPM_15_2013_En_2017-05-25_PostCPM12_InkAm.pdf

 

WARNING: Treatment certificates will not be accepted for wood packing material that is treated in compliance with ISPM 15 BUT not marked as specified in ISPM 15. Shipments not meeting both the treatment and labeling requirements OF ISPM 15 will be considered "untreated."

NOTE TO EXPORTERS: Exporters wishing to use this option should contact the American Lumber Standard Committee. PPQ does not maintain a database for suppliers of wood packing material that complies with ISPM 15. Contact the American Lumber Standard Committee at:

Treatments specified in ISPM 15:

Heat treatment (HT)

Wood packing 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. 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, Chemical Pressure Impregnation (CPI) may meet the HT specification through the use of steam, hot water, or dry heat.

Heat treatment must be indicated by the mark HT. To view the required HT mark refer to: https://www.ippc.int/static/media/files/publication/en/2017/05/ISPM_15_2013_En_2017-05-25_PostCPM12_InkAm.pdf

• Methyl bromide (MB)

 

The treatment is indicated by the mark MB. The minimum standard for methyl bromide fumigation treatment for wood packing material is as follows:

Temperature	Dosage Rate	Hours of Exposure	Minimum Gas Concentration (g/m3
			2hr	4hr	12hr	24hr
21 C or greater	48	24	36	31	28	24
16 - 20.9 C	56	24	42	36	32	28
11 - 15.9 C	64	24	48	42	36	32

The minimum temperature should not be less than 10C and the minimum exposure time should be 16 hours.
