Updated: August 24, 2022

1. APPLICABILITY: These Terms and Conditions of Sale (“Terms”) are incorporated by reference into every quotation, order acknowledgment, invoice or other sales document (collectively, “Sales Documents”) issued by International Engineering & Manufacturing, Inc. and/or its applicable affiliate(s) named therein (“Seller”) to the buyer and/or its applicable affiliate(s) named therein (“Buyer”).

2. OFFER AND ACCEPTANCE: Each quotation issued by Seller and each revision thereof (“Quotation”), whether or not issued in response to Buyer’s request for quotation (“RFQ”), constitutes an offer or counteroffer by Seller to sell the products described therein to Buyer. Alternatively, if no Quotation is issued, Seller’s order acknowledgment and each revision thereof (“Order Acknowledgment”) constitutes an offer or counteroffer by Seller to sell the products described therein to Buyer. Any of the following acts by Buyer shall constitute its acceptance of the Quotation or Order Acknowledgement: (i) acknowledging the Quotation or Order Acknowledgement; (ii) issuing a purchase order, release, scheduling agreement or other similar document for the products on the same or substantially the same terms as reflected on the face of the Quotation or Order Acknowledgement; (iii) accepting delivery of the products; or (iv) by any other conduct which recognizes the existence of a contract for the purchase and sale of the products. Upon Buyer’s acceptance, the Quotation, Order Acknowledgment and other Sales Documents, together with the mutually agreed-upon final drawings, specifications, statements of work and assignment of tasks and responsibilities, as each may be amended from time to time by mutual written agreement of the parties, are incorporated herein by reference and, together with these Terms, constitute the parties’ agreement (the “Agreement”). Neither Seller’s issuance of any Sales Document nor Seller’s manufacture or delivery of products shall constitute acceptance by Seller of any terms and conditions attached to or purportedly incorporated into any RFQ materials, purchase orders, releases, scheduling agreements or other purchasing documents issued by Buyer (collectively, “Purchasing Documents”), and any such terms and conditions are specifically excluded and are not incorporated into the Agreement. For avoidance of doubt, Seller objects to and rejects any additional and/or different terms proposed by Buyer in its Purchasing Documents (or otherwise) and such proposed additional and/or different terms are not part of the Agreement and shall have no effect with respect to any sales by Seller or purchases by Buyer of any products. Seller’s performance under any Purchasing Documents issued by Buyer is expressly limited to and conditioned upon Buyer’s acceptance of these Terms. Notwithstanding the foregoing, Seller reserves the right to reject any Purchasing Document not issued in compliance with the Agreement or any Purchasing Document that purports to include other terms not part of the Agreement. Any quotation issued by Seller shall expire thirty (30) days after its date of issuance, and may be reinstated only by Seller’s written confirmation.

3. PRICES: Prices for products are EXW Seller’s Hope, Michigan facility loading dock (Incoterms 2020) and are subject to change without notice to Buyer at any time prior to Seller’s Order Acknowledgment or shipment of products, whichever is earlier. Unless specifically otherwise agreed by Seller in writing, prices do not include the amounts of any applicable sales, use, transfer, excise or other taxes, tariffs or custom duties, and Buyer will pay directly or be charged by Seller for any such taxes, tariffs or custom duties levied upon the sale, transfer, import or use of the products sold hereunder.

4. PAYMENT TERMS; INTEREST ON LATE PAYMENT; SETOFF: Terms of payment, unless otherwise expressly agreed by Seller in writing, are as set forth on the face of the Sales Documents, or, if not so stated, are net ten (10) days from delivery. Buyer shall make all payments in United States currency. A one and one-half percent (1.5%) monthly service charge, or the maximum permitted by applicable law, will be added for every month or part of a month that the amount due remains unpaid after its due date. Until the products have been paid for in full, Buyer (i) will hold the products subject to a security interest or lien in favor of Seller allowing for the right of repossession by Seller to the extent permitted by applicable law, (ii) will not alter, remove, destroy, or damage any identifying mark on the products or their packaging, and (iii) will keep the products separate from any other goods. Notwithstanding the foregoing, if Buyer becomes delinquent in payment or otherwise fails to fulfill the terms of payment, in addition to and without prejudice to any other legal or equitable remedy, Seller shall have the right to (i) recall or withhold further deliveries of the products until past due payments are made, (ii) immediately terminate the Agreement or otherwise cancel all or any part of any order or release, and/or (iii) declare all unpaid amounts for any products previously delivered immediately due and payable. Buyer acknowledges and agrees that it may not set off or otherwise debit against or recoup from any amounts due or to become due to Seller or any amounts due or become due to Buyer, unless and until Seller agrees in writing to such setoff or recoupment, and Buyer shall not exercise any purported right to setoff, debit or recoupment in connection with any disputed, contingent, or unliquidated claim. In the event Buyer fails to the comply with the foregoing and improperly sets off, debits or recoups from amounts due or to become due to Seller, Seller shall be entitled, in addition to all of its other rights hereunder or otherwise, to withhold shipments of products until Buyer reverses such improper set off, debit and/or recoupment.

5. SHIPMENT; DELIVERY: Unless otherwise expressly agreed by Seller in writing, products will be delivered EXW Seller’s Hope, Michigan facility loading dock (Incoterms 2020). Title and risk of loss of or damage to all products sold will pass to Buyer upon delivery of the products as determined by the applicable Incoterms delivery terms. Shipping dates are approximate only. Orders with indefinite delivery dates are accepted upon the understanding that Seller shall have the right to fill said order as it sees fit and to hold the products for Buyer’s account, at Buyer’s expense and risk, pending receipt of definite delivery instructions. On any individual order or release against an order for products, Seller reserves the right to ship and invoice for a quantity of products which may vary up to ten percent (10%) over or under the quantity specified on the release and Buyer shall accept delivery and pay for such revised quantity and consider the shipment to be complete.

6. EXCUSABLE DELAY; FORCE MAJEURE: Seller shall not be liable or responsible to Buyer, nor be deemed to have defaulted or breached the Agreement, for any delivery delays or nonperformance resulting from (a) delays in receipt of final specifications or instructions from Buyer, (b) changes in specifications, or (c) a force majeure event, including, without limitation, strikes, labor disturbances, material shortages, nonperformance by subcontractors or suppliers, abnormal manufacturing conditions, delays or failures of carriers, telecommunications breakdowns, fire, flood, storms, riot, war, terrorism, invasion, governmental orders, acts of God, pandemics, epidemics, or other similar or dissimilar events beyond Seller’s reasonable control (“Force Majeure”). For avoidance of doubt, to the extent that any such failure or delay causes Seller to reduce or suspend its production or deliveries, the time for Seller’s performance shall be automatically extended for so long as required for Seller to overcome such failure or delay. Upon the occurrence of a force majeure event, Seller shall have the right to immediately terminate the Agreement or otherwise cancel all or any part of any order or release without liability to Buyer. Cancellation of any part of an order shall not affect Seller’s rights to payment for any products delivered.

7. INSPECTION: Buyer agrees to inspect products delivered by or for Seller within ninety-six (96) hours after delivery in accordance with the Incoterm delivery term for patent nonconformities, including, without limitation, with respect to quantities, packaging, materials, and workmanship, and all products delivered shall be conclusively deemed accepted and to conform to contract requirements unless Buyer provides Seller notice of a potential non-conformity in writing within such ninety-six (96) hour period. In such event, Seller will have the opportunity to inspect and conduct a root cause of the allegedly affected product(s) to determine whether the product(s) are Non-Conforming, as provided in Paragraph 9 hereto.

8. ORDER CANCELLATIONS: UNLESS OTHERWISE MUTUALLY AGREED IN WRITING, NO ORDER MAY BE CANCELLED BY BUYER NOR WILL SELLER CONSENT TO ANY CANCELLATION UNLESS BUYER PROVIDES WRITTEN NOTICE TO SELLER AT LEAST ONE HUNDRED EIGHTY (180) DAYS PRIOR TO THE AGREED-UPON ESTIMATED DELIVERY DATE. If Buyer cancels an order or any portion of an order in less than one hundred eighty (180) days prior to the agreed-up estimated delivery date and/or without Seller’s express written consent, Buyer agrees to pay Seller, at a minimum, a reasonable cancellation fee (“Cancellation Fee”). Unless otherwise mutually agreed in writing, the Cancellation Fee shall be fifteen percent (15%) of the total amount of Buyer’s cancelled order. Seller also reserves its right to recover from Buyer any and all damages, costs and expenses incurred by Seller as a result of Buyer’s cancellation, including, without limitation, those necessary to compensate Seller for any loss in profits that it may suffer in the event that Seller is unable to resell the products at the contract price.
