On July 4, 2005, Bolivia notified other countries that effect as of May 24, 2005, it has required that wood packaging materials meet the International Plant Protection Convention guidelines for wood packaging materials, ISPM 15. 

The Bolivian regulations (see link below at page 8 (Spanish only)), require that for imported wood packaging the wood packaging is to be constructed from debarked wood and treated and marked according to the ISPM 15 standard.  However, there are no requirements that the wood be marked as manufactured from debarked wood.  Wood packaging made from unmarked wood may be retained and either treated, destroyed or re-exported.  If the wood packaging is marked according to the ISPM 15 standard and infested (or showing signs of live pests), the officials may take action and notify the national plant protection agency of the country of origin.
