Micro and small companies are essential for the economy, as they gen- erate employment and income. The cosmetics industry in Brazil has been empha- sizing international trade and micro and small companies are looking for other markets to conquer new clients and new partners, but the process for internation- alization finds barriers. The focus of this paper is to identify and verify if the barriers are similar for both micro and small entrepreneurial companies. To meet the objective, a research was carried out with 41 micro and 115 small cosmetics companies. The data collection was carried out through a questionnaire, whose results are shown to be the same for micro and small enterprises, as they are: the difficulty to make changes in the products destined to external customers' de- mands, exchange rate fluctuations, delay in receiving the payments from com- mercialization and difficulties in obtaining capital. Keywords: Micro and Small Companies, Cosmetics, Barriers 1 Introduction According to the Brazilian Support Service for Micro and Small Companies - Sebrae [1] from the 1980s the Micro and Small Companies were gaining ground in Brazil and over time were gaining representativeness. On December 14, 2006, Law 123 was cre- ated establishing the Statute of Micro and Small Companies, which advocates the es- tablishment of a differentiated tax burden for such companies. Once companies operate regionally, many of them seek new markets and strive to win international clients. Rasmussan and Madsen [2] emphasize the need for prior plan- ning, knowledge of market, legislation requirements and of tariff and non-tariff barri- ers. Cosmetics companies operating in Brazil, have shown growth in exports. Data from the Brazilian Association of the Personal, Perfumery and Cosmetics industry - ABHIPEC show that, from 2006 to 2016, exports grew more than 293% in the pe- riod[3].
