As consumers become more informed of the quality and products that are being sold in the market, the use of certification marks has become a standard for many manufacturers to enhance their image and customer perception of their products.
Some of the marks are not mandatory and some are. For example, most products that are sold in the North America market will have UL mark on them even though it may not be mandatory. It has in a way become a standard in this part of the market to have this marking.
The use of certification marks indicates that the product has gone through successful test based on a certain test standards for that particular product. It also assured the consumers that the manufacturer is being regularly audited on the materials and production processes to ensure that the standards are being adhered to.

It is therefore critical for the management to identify and study the product life cycle and the market before deciding to apply for the marking.
