Pallets revolutionized rail transport about 100 years ago in that they made loading faster and they have revolutionized warehousing. Do not go for a pallet that is not treated. The best pallets are heat-treated pallets.
The main reason for this is the fact that there are claims that the fumigation process of treating pallets, which makes use of methyl bromide, is harmful to the environment since this chemical is toxic. So, what makes a good heat-treated custom wooden crates supplier?
Go for a pallets wooden supplier who is certified for International Standards for Phytosanitary Measures number 15 or ISPM 15 since this is an indication that they are credible and reliable. You could check the stamp to verify this. Pallets that do not use ISPM 15 Certified Heat Treating will not be accepted in the International Plant Protection Convention or IPPC member countries.
Ensure that the heat-treated pallet supplier you go for does the heating properly. The treatment should be done at 132.8 F (56 C) and this should go on for 30 or so minutes. Such pallets come with the initials HT, but you should get other proof that this has been done.
The supplier you go for should be registered by the relevant industry and government regulatory bodies. Examples of such bodies are the EPA in the U.S. and the Timcon and Forest Service and Forestry Commission. This is the only way to ensure that you get a reliable and credible heat-treated pallets supplier.
Only go for a supplier who can give you more than pallets wooden. The supplier should offer you advice on such issues as the best pallets for your particular needs. The supplier should also offer other services such as picket fencing, the manufacture of wood packaging products like timber packing and plywood cases, pallet collection, remanufacturing, and recycling.
