    Zika Virus Fumigation Concerns


    There have been many incoming calls related to China's fumigation and certification requirement to kill mosquitoes in containers due to concerns related to the Zika Virus. If a customer contacts you regarding this please advise them this is not related to the ISPM 15 program or the wood packaging material you are providing.  China is requiring the entire container (including the consignment) fumigated prior to shipment to make sure any mosquitoes that may be in the container and potentially carrying the Zika virus are killed.  ISPM 15 relates only to pests that can attack and kill trees.  If any WPM customer needs further clarification they can contact their local APHIS Export Certification Specialist at this link:  APHIS Export Certification Specialist


    Processing Reused WPM



    ISPM 15 states in Section 4.3.1 "A unit of wood packaging material that has been treated and marked in accordance with this standard and that has not been repaired, remanufactured or otherwise altered does not require re-treatment or reapplication of the mark throughout the service life of the unit."  Reused WPM (formerly known as Pass-throughs) is further defined by ALSC in their clarifications "that remanufactured WPM or repaired WPM where any doubt exists as to the heat treat compliance of all components shall have any existing ISPM 15 quality marks obliterated. This applies not only to a WPM manufacturer remanufacturing or repairing WPM onsite, but also applies to situations where that WPM manufacturer is aware the WPM has been remanufactured or repaired. Examples include sending WPM offsite to another facility to facilitate remanufacture or repair, bringing in WPM from a supplier known to be a remanufacture and/or repair operation, and receiving WPM from sister facilities remanufacturing or repairing WPM. In effect, any WPM known to have been remanufactured or repaired where any doubt exists as to heat treat compliance of all components shall have original IPPC quality marks removed."  (Ratified by ALSC November 7, 2014)  In any situation where used WPM is coming into a facility and any material is replaced or it appears to have been repaired in the past, the old marks will need to be obliterated, the WPM retreated and new marks applied for the WPM to conform to ISPM 15. 

  • Information Related to Add-Ons

    When combining or adding on to previously IPPC stamped (from another source) WPM (pallet, skid, crate, etc):

    1. The added WPM (either a single piece or multiple component WPM) must have the IPPC stamp applied, or
    2. The previously IPPC stamped WPM must have the marks obliterated.

    When combining or adding on to non IPPC stamped WPM the added WPM cannot be stamped unless the non IPPC WPM in question is heat treated and stamped by the facility.

    Scenario:  IPPC stamped pallets from an outside source are brought in and had a box added to the pallet by the facility; either the box MUST be IPPC stamped by the facility or the stamps must be obliterated on the pallet.

    Scenario:  Non-stamped pallets are brought from an outside source and had a box added to the pallet by the facility; the box CANNOT be IPPC stamped by the facility since the pallet was not certified (stamped) by the original supplier.

    NOTE:  Both the base (pallet) and the addition (box) must be either IPPC stamped or neither may be stamped. There are 2 certifications involved and each are separate.

    In regards to situations where there are multiple but individual add-on pieces that are not connected in any way, a single mark on one piece on opposite sides of the WPM is sufficient to identify all individual add-on pieces as a unit of add-on WPM.  Each piece does not have to be marked.  In sensitive areas more markings are recommended but this is all that is required by ALSC.
