Myth: 'I have used my supplier for years and they tell me their product meets the mandatory standard. Therefore I don’t need to ask them for proof that the product complies.'
Fact: Suppliers at all levels of the supply chain are responsible for ensuring their products meet mandatory standards.
While you can visually check some safety requirements such as warning labels, performance and strength requirements need qualified and accredited testers with the right equipment. If you are not the manufacturer, you need to be sure that the products you sell meet their mandatory standards.
