High-quality cosmetic goods are often the target of grey market shifts to the detriment of brand owners. In addition, this causes price fluctuations in the market, which reduces customer loyalty. For this reason, more and more producers are opting for individual coding of the folding boxes of cosmetic products (grey market code), as well as "track & trace" coding at higher packaging levels such as outer cartons and pallets. This allows the flow of goods to be tracked seamlessly all the way to the target markets, enabling grey market shifts to be identified and the responsible retailers to be held accountable. In addition, the system can be used for targeted customer approaches, which increases customer loyalty and enables further market assessment.
