1. Export to USA: UL Marking :
For exporting your products to united states of America, your product should be certified as UL (Underwriters Laboratories)
is an American worldwide safety consulting and certification company headquartered in Northbrook, Illinois. It maintains offices in 46 countries. UL was established in 1894 and has participated in the safety analysis of many of the last century's new technologies, most notably the public adoption of electricity and the drafting of safety standards for electrical devices and components.
UL provides safety-related certification, validation, testing, inspection, auditing, advising and training services to a wide range of clients, including manufacturers, retailers, policymakers, regulators, service companies, and consumers.
UL is one of several companies approved to perform safety testing by the US federal agency Occupational Safety and Health Administration (OSHA). OSHA maintains a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories.
2. Recognized Component Mark :  The "Recognized Component Mark" is a type of quality mark issued by Underwriters Laboratories. It is placed on components which are intended to be part of a UL listed product, but which cannot bear the full UL logo themselves. The general public does not ordinarily come across it, as it is borne on components which make up finished products.
3. Export to Canada: CSA Mark
The CSA Group (formerly the Canadian Standards Association or CSA), is a not-for-profit standards organization which develops standards in 57 areas. CSA publishes standards in print and electronic form and provides training and advisory services. CSA is composed of representatives from industry, government, and consumer groups.
CSA began as the Canadian Engineering Standards Association (CESA) in 1919, federally chartered to create standards. During World War I, lack of interoperability between technical resources led to frustration, injury, and death. Britain requested that Canada form a standards committee.
The CSA registered mark shows that a product has been independently tested and certified to meet recognized standards for safety or performance.
