Suppliers should encrypt and compress the quotation list and related attachments (which need to be stamped with the official seal and scanned in color) into a zip format before the quotation deadline, and only send the encrypted compressed package to the Jinfeng Laboratory procurement email jfsys-caigou@jflab.ac.cn. The decompression password and project quotation amount must not be entered in the body of the email, otherwise it will be treated as an invalid quotation. The password will be notified separately after the expiration date by the purchaser. Those who do not quote before the quotation deadline will be deemed to have given up automatically. The subject of the email must be filled in strictly in accordance with the format: [Full name of the project] + Supplier’s complete unit name + Quotation document. If the subject is filled in incorrectly, causing the purchaser to be unable to identify and classify the email, and the risk of the email being misjudged as spam by the system is borne by the supplier.

7. Quotation document requirements

1. The supplier’s quotation document should contain the following attachments:

(1) Quotation letter

(2) Quotation list

(3) Legal representative qualification certificate (if the bidder is an authorized representative, he must also provide a legal representative authorization letter)

(4) Statement

(5) Letter of commitment

(6) Business license or other organizational entity certification documents

(7) Performance certificate/professional qualification (if any)

2. The bidder should prepare a freshly stamped quotation document (PDF) and send it to the mailbox. The quotation document must be clearly visible, otherwise the quotation will be deemed invalid.

3. The quotation document should be produced in accordance with the requirements of the "Purchase Announcement". The quotation document must be signed and sealed by the legal representative of the bidder or his authorized representative at the prescribed signature place. The signature, seal and content should be complete. If there are any omissions, you will bear the risk of being deemed an invalid quotation.

4. The quotation document should be written clearly and neatly.
