If the application is submitted online but contains non-database descriptions of goods/services, each type of goods and services will be charged S$341; if the application is submitted offline (Form TM4), each Category 1 goods and services are charged S$374. You can find a Singapore trademark application agency to handle it for you. After all, professional people will be more comfortable handling this matter. I recommend Singapore Fu Zhilin Group. Their company has rich experience.
