What are the Wood Packing Material Requirements?

All wood packing material must be marked and treated by either of two methods, heat treatment or methyl bromide. Examples of WPM includes but not limited to pallets, skids, pallet collars, containers, crating/crates, boxes, cases, bins, reels, drums, load boards, dunnage. Wood packaging made of exempt materials but combined with solid wood components must still be treated and marked. Enclosed is the example of the marking which contains the Country where it was marked, the facility identification code that treated the WPM, the treatment method, and the inspection agency logo.

Failure to treat or properly mark each pallet in the shipment will result in inadmissibility and the cargo will be refused by Agriculture. ALL WPM must be visible, and clearly marked. Multiple IPPC logos belonging to various treatment facilities within the same and/or added wood pieces to reconstruct a pallet that is not marked will also result in a refusal.
In the following link you will find WPM requirements for each country:

What are the different types of Import Alerts with FDA?


There are two different types of automatic detention. One is caused when the shipper has been sampled and found violated. This causes the shipper to be placed on an import alert and placed on a list known as Detention without Physical Examination which is known to be a red list. 

This link has a list of all the import alerts from Mexico:


The second type of automatic detention is based on a few commodities. At the moment these commodities for Mexico are dry pepper, dry tamarind, and papayas. These commodities are considered to be of high risk and require a private lab analysis unless the shippers have met the criteria and are placed on a list of exclusion of Detention Without Physical Examination which is also known as the green list. If the shipper is in the list in the enclosed link then they are exempt from having to do private labs.

Dry Peppers: Import Alert 24-11 

Dry Tamarind: Import Alert 21-07 

Papayas: Import Alert 21-17
