1. Procurement types of OIST

 OIST's procurement is regulated to be conducted through selection of business partner by price competition in principle. Multiple quotation comparison will be adopted to the range 1.5 million JPY or more and less than 3.0 million JPY (or, if the Requesting Unit is a research unit or section managed by the Provost, less than 5.0 million JPY). Public tender will be organized in the range 3.0 million JPY or more (or, if the Requesting Unit is a research unit or section managed by the Provost, in the range 5.0 million JPY or more). Above JPY equivalent will be calculated by OIST internal fixed monthly exchange rate (not by realtime TTC/TTS).
 In the cases like selection by quality examination (not only its price), several proposal methods will be accomplished, and some cases are including negotiation events about contract terms and conditions.

Besides, information of OIST's tender announcement and past contract records are available at separated webpage (please refer to below links).

Procurement Information (including construction items)
List of Past Contracts

*For documentation regarding tender, please follow the required documents when applying tender.


2. Contract terms and conditions

 For transactions valued 3.0 million JPY or more (or, if the Requesting Unit is a research unit or section managed by the Provost, in the range 5.0 million JPY or more), contract agreement will be established by case using OIST's standard contract form(s) shown as below.

*Above forms are described along OIST's general transaction terms and conditions, and some adjustment will be proposed according to actual transactions.
*Please refer to the webpage for OIST's rules and procedure related to procurement, for more information including detail stipulations about business transaction.


3. Placing purchase order from OIST

 Order will be placed by the authorized staff in the OIST procurement section in principle.

 An exception, only transactions valued 1.5 million JPY or less, OIST regulation allows that order form will be provided by research units or administrative sections directly to the business partners. In such cases, please inform persons in charge in each unit/section with order receipt.

 Order from OIST will be placed essentially by the official "Order Form" (PO) or contract agreement. Please carefully be noted that OIST can not make payment for transactions without issuing official "Order Form" for both goods sales/purchase and services, since it will not be accepted as OIST's transaction. Our business partners are requested to prevent issuing order receipt without OIST's official "Order Form", like just via telephone or email.
 Besides, if you received several PO forms which separated each below 1.5 million JPY from the same person at the same day, it may be concerned as inappropriate split order described in following "7. Contact window for illicit or inappropriate action". Please do not issue your order receipt, and ask the person in charge about such compliance.

 OIST places purchase order based on your quotation (or similar price estimation). It would be appreciated if we could receive it as electronic file like PDF. Paper-basis master copy of quotation will be required at delivery, so please includ it to delivery package when shipping. Master copy is requested to have logo or trade mark of your company (at ordering, it will be accepted without such symbol), printed date and signature or seal by the representative of your company. If your company is operated in abroad (not in Japan), it is not necessary to provide paper-basis master copy (we can accept e-file solo).
In OIST, only for transaction values 1.5 million JPY or more, specification with requirement sheet (quotation request form) is essential to be presented from OIST employee to business partner at request for quotation. Specification sheet will be attached to "Purchase Order", therefore, when there was not established specification sheet by OIST in such price range above, please contact requesting person in charge.

OIST's nominee for contract agreement/application forms
OIST stipulates that nominee of university for PO or contract shall be authorized by the CEO of the school corporation in principle. Only authorized persons in charge can make signature, and/or seal onto your company's format like contract agreement, application forms and other documentation which certifies establishing the transactions.
OIST cannot accept any of such documentation signed/sealed by non-authorized staff of the university, even your company's regulation does not care about its authority. Thank you very much for your careful attention.

8. Special requests for your cooperation

[At the auditor's inspections]

 OIST's transaction and budget execution are carefully checked by the Board of Audit of Japan and OIST internal audits. When necessary to submit transaction data to them, we perhaps ask you for your cooperation for disclosure of the data or documents in your company, or some questionnaire about procurement in OIST.  We deeply appreciate your kind support and cooperation.

[At the end of fiscal-year]

【Request for early issuing of bills/invoices】

OIST requests all business partners that early issuing and sending bills/invoices for transactions include goods/services delivered within March 31 (date of closing of OIST accounting) to make arravial of the documents by 2nd business day of April.
In the cases of unavoidable delay, please email/FAX with photocopies or e-files within above deadline.
We are deeply afraid to bothering you in busy season at the end of the fiscal year, but it would be appreciated to your kind cooperation.

Contact for issuing bill/invoice: OIST Accounting Section

【Operations when delivery will be crossing fiscal years】

As soon as it becomes clear that the items will not be delivered by the end of March, we will cancel them. In that case, they will be reordered as soon as it becomes April. This processing is necessary because the order will straddle two fiscal years, but we have no intention of cancelling the order itself.

In such case, OIST requests issuing of partial delivery slip, bill/invoice and its quotation only for the items delivered before the end of the fiscal year. We are afraid to bothering you, but it would be highly appreciated to your understanding and kind cooperation.

If the delay of delivery of the object items/services from the end of fiscal year would be clearly indicated, OIST does not issue a PO for such transaction by correspondent budget. It would be appreciated if you could notify OIST person in charge of the transaction when you find out such fiscal-year-crossing matter of the lead time.
