The development of sustainable products is a full growth area due to current legislation, mainly in Europe and the United States. Electronics products have increasingly short life cycles, which imposes the need to exchange information more dynamically, accurately and timely, for preventing failures in the survey, interpretation and application of information during the stage of product development, ensuring compliance to existing regulatory frameworks. Products need to be designed based on structured information. Capturing the desires and needs of customers and turning them into requirements and design details for the purpose of compliance to the RoHS regulatory framework is a complex task due to the multitude of information, not always correlated. Hypothetically, the use of a single definition model that captures a spatial, behavioral and procedural description of the product can help reduce the current waste of resources and quality assurance in the development process. The present work aims to develop a product definition model for meeting the RoHS directive. This is done by proposing a formal ontology that potentially promotes interoperability of information systems that are used throughout the production chain in the electronics industry. The model is under development and is to be checked for suitability in the context of the Brazilian electronics industry.
