Starting a manufacturing business in the agricultural industry, food industry, electronics industry, or aerospace industry should be your top choice. These industries have increasing demands proportionate to the economic growth of Thailand.
Of course. Agricultural businesses contribute about 6% to Thailand’s GDP. It also creates employment for over 30% of laborers in Thailand. Setting up a manufacturing business in the agricultural industry has a high chance of success.
Manufacturing businesses in the electronics industry face the highest competition. As of November 2024, the electronics industry contributed about 14% to the overall export of manufactured products. So, opening a business in this industry can be profitable and challenging at the same time.
Not always. Manufacturing businesses need at least one Thai partner if they don’t have a foreign business certificate or a BOI promotion certificate. With any of these certificates, manufacturing businesses can operate without having Thai partners.
It depends on the investment capital, business strategy, target market, and other factors. New entrepreneurs should start with light manufacturing businesses. Experienced investors with large investment capitals can tap into the heavy or advanced manufacturing industry.
Registering a manufacturing business won’t take more than a few weeks. But, getting the BOI promotion certificate can take about 100-150 days. Then, it will depend on the factory size, machinery, etc. Registered companies must commence their operation within 36 months of registration.
