How do I choose the ISIC category of my company? Boris May 22, 2018 13:18 Updated ISIC (International Standard Industrial Classification) is the United Nations system for classifying all economic activities. It is used internationally. Please note that the classification is based on the company’s activity, not on the product (e.g. for a same product, the activity can be either manufacturing or wholesale). Please select the category which is the most similar to your activity. If you are not sure of your ISIC category, you can select more than one. You may also put this information in your activity description. Please be assured that we will check your ISIC information once we receive your completed registration.
