The Government Procurement (GP) Chapter of JSEPA mainly follows the WTO Government Procurement Agreement (GPA), which, both Singapore and Japan are members of. The threshold for bidding for central govt contracts for goods and services (apart for construction, architecture, engineering and some other technical services) has been brought down from SDR 130,000 to SDR 100,000.

With a reduced threshold, more governmental purchases by both Parties will be subject to the non-discriminatory, open and competitive tendering procedures. This would represent an increased chance for a Singapore supplier to respond and win the tenders from the Japanese Government (and vice versa).

All other aspects of the GP Chapter in JSEPA follow the WTO GPA and thus information as to the procedures for GP can be obtained from the Annexes of the GPA. Under the GPA, Singapore-based companies can bid for the provision of goods and selected services by 21 government ministries and agencies and 77 government-related entities. Entities will publish a notification in Kanpo (the official Government gazette) of their request for the materials and other necessary information on basic requirements for scheduled procurement, and will provide copies of the notification to suppliers upon request. Kanpo is published in Japanese, daily, by the printing bureau of the Ministry of Finance.

Notifications in Kanpo will clarify the following:

Except in cases of urgency, the deadline for submission of material is usually set at least 30 days after the day following publication of the request for submission of materials. All central government and all sub-central entities including prefectural governments entitled "To", "Do", "Fu" and "Ken", and all designated cities entitled "Shitei-toshi", are covered under the government procurement chapter.
