TAITRA's four local branch offices in Hsinchu, Taichung, Tainan, and Kaohsiung provide services to companies outside metropolitan Taipei. Through these domestic offices, TAITRA is able to maintain close contact and interaction with local companies in their respective areas and provide direct and substantial services in areas such as feature trade promotion, business information, market seminars, and on-the-job training.

As a trade promoter and consultant, TAITRA is well-equipped to help identify the actual needs of individual companies and industries. Moreover, it has the resources to offer other trade and business services.

AITRA staff visited local companies and factories regularly. In addition, they also visited local government offices, industrial parks, industry promotion associations, and export zones of the MOEA to collect information on investment incentives and other useful topics for the domestic business community.

To help local companies understand more about world economic trends and the international market, TAITRA domestic offices conduct trade and business-related seminars regarding various issues on a regular basis.

Thousands of trade publications, periodicals, CDs, and non-publication information were collected and displayed at TAITRA's five domestic trade libraries. In 2006, a total of 81,208 visitors benefited from the trade information and statistics databases managed and operated by these libraries.

To meet the needs of the local business community, TAITRA offers various trade-related and foreign language courses at its four domestic offices. Through these programs, TAITRA hopes to provide local businesses with well-trained staff whose enhanced professional marketing skills can help their international businesses operate more efficiently.
