[EN] The present Final Degree Project is developed in the company TORRECID S.A in Alcora, province of Castellón. This company is a multinational of the chemical sector that supplies products mainly to the sectors of glass and ceramics. The products are marketed internationally, for this it¿s necessary to obey the legislation of the country of origin and destination of the product. The objective of this work is to establish a protocol for the commercialization of the products that way to comply with the requirements of the adaptations of the Globally Harmonized System (GHS) of Classification and Labeling of Chemical Products in European Union, China, Japan and Korea. For this it is necessary to know the existing legislation in those countries and establish the differences between them in order to be able to constitute a procedure based on the identification of physical, health and / or environmental hazards. It will be necessary to take into account the classification criteria and cut-off values for each country. Once the GHS classification has been carried out according to the particularities of each country, it will be essential to take into account the specific requirements of each country in the hazard communication methods, which are the labels and safety data sheets.
