Dangerous goods, as defined by the Transportation of Dangerous Goods Regulations, are non-mailable matter.

Purolator is currently the only Canadian courier on Machool that accepts them, and only if your company has a certified Dangerous Goods Specialist and the commodity is an accepted one. Select "Dangerous Goods" in the service options when you create the shipment.

Check with the courier on their own requirements for anything needing special labelling or handling. Some shipments need extra forms or labels that have to be produced outside Machool.

Broadly, any mail that:

• Is prohibited by law, such as illegal items, obscene material, or anything that may not be imported or sent by mail
• Fails to meet certain physical characteristics or marking requirements
• Contains products or substances that could injure handlers, damage postal equipment, or trap other items
• Contains sexually explicit material, unless sent in an opaque envelope marked "ADULT MATERIAL" or similar

You are solely responsible for confirming an item is acceptable for mailing. See the Non-mailable Matter Regulations under the Canada Post Corporation Act.
