Re: What is the difference between Heat Treatment and Eradication?
Eradication is used to describe the process of making the wood packaging free of pests. Heat treatment is one approved method for doing this in solid wood packaging. The other approved method is Methyl Bromide Fumiigation.
There are time and temperature requirements under both methods, but there is also a dosage requirement where the methyl bromide gas is concerned. At this time, these are the ONLY approved methods of eradication. However, other methods are currently being studied, to determine their effectiveness, as well. Some of these other methods include Chemical Pressure Impregnation (pressure treating), radio waves and vacuum treatments, as well as other fumigants besides methyl bromide.

Regarding different types of stamps...
There is ONE standard format for the stamp, brand or stencil (no labels permitted), which indicates compliance with the international standard, ISPM-15. However, the country code within that stamp changes depending on what country the wood packaging originated in. The method of treatment must also be identified within the mark, so it will say HT if heat treated, or MB, if fumigated with Methyl Bromide.
