Accepted timber permanent preservative formulations

This page lists timber preservative formulations (by chemical class as a list of acceptable trade names) that the department has approved for use as biosecurity treatments as well as the minimum preservative retention requirement for each formulation. To be accepted by the department, preservative treatments must also be applied using an appropriate method and meet penetration zone requirements as outlined on the Timber permanent timber preservative treatments webpage.

Please note that the department no longer assesses new formulations. For any preservative formulations not listed below, check to see if they meet the biosecurity requirements for compliance to the Australian Timber Preservation Standards.

For acceptable preservatives the minimum retention of active ingredients required is given below as %mass/mass. Use the following equation to convert retention (%mass/ mass) into retention (kg/m³):​​​​​

Retention (kg/m3) =

Retention (%mass/ mass) x Density of plywood (kg/m³)

100

Preservatives for​ treating solid timber

The department accepts the preservative formulations listed below for impregnation treatments of solid timber (lumber, timber packaging/dunnage, wooden articles, unbonded glulam components) and unbonded timber veneers of maximum 5mm thickness.

Water borne ti​​mber preservatives

2.1.1 Copper chrome arsenic (CCA) timber impregnation preservatives

These timber preservatives are mixtures of various compounds of copper, chromium and arsenic.

Preservatives of this type must be formulated from either salts or oxides of bivalent copper, hexavalent chromium and pentavalent arsenic. In the formulated preservative and the solution used to treat the timber, the ratio of these active elements shall fall within the following limits

  • Copper: 23-25%
  • Chromium 38-45%
  • Arsenic 30-37%.

The minimum concentration of CCA-type preservative in the zone required to be penetrated shall be 0.320% mass/mass (elemental copper + elemental chromium + elemental arsenic) based on the oven dried mass of the wood. This is deemed to be the minimum retention requirement.

Calculation of preservative retentions relies on a number of assumptions. These are listed in the example below. Minimum retention for each CCA preservative may be calculated as follows:

  1. Each elemental concentration of copper, chromium and arsenic is converted to the form in which it appears in the formulation, i.e.
    • %Cu to % Cu formulation e.g. % Cu to % CuSO4.5H2O
    • %Cr to % Cr formulation e.g. % Cr to % K2Cr2O7
    • %As to % As formulation e.g. % As to % As2O5.2H2O
  2. Formulation concentrations are then added to provide a Total Formulation Value (TFV); i.e.
    • % CuSO4.5H2O + % K2Cr2O7 + % As2O5.2H2O = %TFV
  3. The % TFV is then multiplied by the wood density/100. In the absence of more detailed information, 500 kg/m3 may be assumed as the wood density value for Pinus timbers and 1000 kg/m3 assumed as the value for hardwoods, therefore;
    • %TFV x wood density/100 = piece retention

In general, piece retention is about 60% of charge retention and so Charge retention = piece retention x 1.6.

The CCA timber impregnation preservative formulations that appear in Table 2.1.1 are acceptable as biosecurity treatments for solid timber and unbonded timber veneers.

Accordingly these two formulations are onlyaccepted as a glueline treatment for plywood manufactured from hardwood substrates. Tailileum 200 has not been tested for European beech and therefore it is not accepted for use with this species.

Treatment certificates must state veneer thickness.

3.2.3   Imidacloprid timber glueline preservatives

Timber preservative formulations containing Imidacloprid that appear in Table 3.2.3 are acceptable as biosecurity treatments for plywood and LVL.

Accordingly, these formulations of Imidacloprid are only accepted as a glueline treatment for plywood manufactured from hardwood substrates. Tailileum 400 was tested on Keruing/ Eucalyptus plywood and birch/ larch plywood. 

Treatment certificates must state veneer thickness.

3.2.4   Bifenthrin timber glueline preservatives

Timber preservative formulations containing Bifenthrin that appear in Table 3.2.4 are acceptable as biosecurity treatments for plywood and LVL.

Supraleum 2006 CY 1.6mm - - 0.075
Supraleum 2006 A-CY 1.6mm - - 0.024

Note: Efficacy tests for Radaleum FAP and Radaleum HP were conducted on Radiata pine (Pinus radiata D. Don) plywood. Accordingly, the above Radaleum FAP and Radaleum HP formulations of Cypermethrin are only accepted as a glueline treatment for plywood/LVL manufactured from softwood (coniferous) substrates. Radaleum FHP – 60 has been tested on both softwood and hardwood plys.

The efficacy tests for the above Tailileum 300, Cypermethrin and Alpha-cypermethrin formulations were conducted on keruing plywood. Therefore it is only accepted for use in hardwood substrates. Tailileum 300 formulations containing beta-cypermethrin are not accepted by the department.

Treatment certificates must state the veneer thickness.

3.2.6   Neonicotinoid timber glueline preservatives

Formulations containing Neonicotinoids that appear in Table 3.2.6. are acceptable as biosecurity treatments for softwood plys and LVL.
