While the country's mask-making industry is relatively small, it's expected to grow significantly in the coming years. Globally, the habit of wearing masks is catching on and India is set to become the leading supplier of medical masks in the future. In Europe alone, demand for medical masks is estimated to be at least $150 million pieces per month. Each buyer determines what type and model of masks they'll need each month. In addition to India, China, Thailand, Vietnam, Indonesia, and Brazil are major suppliers of surgical masks.
