  • MARKS RELATED TO ISPM 15 CONFORMANCE

    There are three marks involved in the process of creating ISPM 15 conforming wood packaging material (WPM).  When applied each mark must be fully legible meaning all elements of the mark must be capable of being read or distinguished.  This includes the border for the IPPC mark.  These three marks are described in greater detail below.

  • HT Mark

    TP HT Mark

    The HT mark identifies individual pieces of lumber or lumber components as being heat-treated in conformance with ISPM 15 standards.  The mark contains 3 elements; the facility number, the letters "HT" and the agency trademark.  The HT mark must be applied legibly a minimum of one time per individual piece and 100% of pieces must be marked (a special provision is made for "small" pieces).  The mark serves in establishing a chain of custody between the site that treated the raw materials and the facility that will certify finished WPM as ISPM 15 conforming.  This mark is NOT recognized as a replacement for the IPPC mark.

  • IPPC Mark

      

    The IPPC mark identifies multi-component WPM (i.e. pallets, crates, boxes, etc.) as being heat treated and debarked in compliance with ISPM 15 standards.  In addition to the 3 elements of the "HT" mark, the IPPC mark also includes a country code and the IPPC "wheat" symbol.  The IPPC mark should be legibly applied a minimum of 2 times with a mark placed on opposite faces of the WPM.  These marks should be visible on the WPM so they can be easily seen by Customs if inspected.  If the WPM is made up of solid and processed wood materials (i.e. engineered or corrugated board product), ISPM 15 states "where various components are integrated into a unit of wood packaging material, the resultant composite unit should be considered as a single unit for marking purposes. On a composite unit of wood packaging material made of both treated wood and processed wood material (where the processed component does not require treatment), it may be appropriate for the mark to appear on the processed wood material components to ensure that the mark is in a visible location and is of a sufficient size."  To be safe, if you're dealing with a box where solid wood is used as an exterior frame place the IPPC mark on the solid wood frame and not the engineered or corrugated material.  If solid wood is used as an interior frame, you should place the IPPC marks on the outside of the box on the processed wood material but also place marks on 2 opposite pieces of the interior frame so Customs can see them on the solid wood frame in the box if it is opened at port.

  • IPPC DUN (Dunnage) Mark

    The IPPC DUN (dunnage) mark typically identifies individual pieces of solid wood used for blocking or bracing as being heat-treated and debarked in conformance to ISPM 15 standards. The DUN mark includes all the elements of the standard IPPC mark but will also include the term "DUN" or "Dunnage" on it.  This mark is required to be legibly and visibly placed once on each piece of dunnage. If treated wood is being sent as dunnage to another facility where it will require further cutting, the dunnage mark should be placed in way where each cut piece would have a full mark displayed on it after cutting.  Pieces of wood that do not include all the required elements of the DUN mark should not be used for dunnage.  Examples where the dunnage mark would be permissible to use include where a wood piece is attached to opposite ends of a long corrugated pipe box, when bracing is employed in the back of a container or when a piece of wood blocking is used to prevent metal banding from marring equipment.  If you're uncertain whether the use of a DUN mark is appropriate in a specific application please contact your inspector or the Conyers office.
