Last updated: 05/29/2024

1. Applicability

These terms and conditions of sale (these “Terms“) are the only terms which govern the sale of products manufactured by or for, or products distributed by Seller (“Products“). For purposes of these Terms, “Seller” shall mean MBL International Corporation and its divisions, subsidiaries and affiliates and their successors and permitted assigns and “Customer” shall mean any person or organization purchasing Products from Seller.

These Terms and Conditions shall apply to all transactions between Seller and Customer, unless there is a written contract signed by both parties in existence covering the sale Products covered hereby. In that event, the terms and conditions of said contract shall prevail to the extent they are inconsistent with these Terms. These Terms prevail over any of Customer’s purchase order or general terms and conditions of purchase regardless whether, when or how Customer has submitted its purchase order or such terms. These Terms shall also apply to the exclusion of any terms implied by trade, custom, practice or course of dealing unless otherwise agreed to upon by Seller in writing. Fulfillment of Customer’s order does not constitute acceptance of any of Customer’s purchase orders or terms and conditions and does not serve to modify or amend these Terms.

Seller may amend these Terms from time to time by posting a new version on its website ( Please re-read these Terms before placing each order because, by placing such order after a revised version of these Terms has been posted, Customer shall be deemed to have accepted the revised version.

Each shipment will constitute a separate sale, and Customer shall pay for units of Product shipped whether such shipment is in whole or partial fulfillment of Customer’s purchase order. Seller will use reasonable commercial efforts to deliver the Product(s) by the requested delivery dates set forth in the Order. Both Seller and Customer understand that the requested delivery dates are good faith estimates that are not firm commitments.

For protocol-related issues, Seller’s technical services team will provide reasonable independent advice. For Product-related defects, a replacement or credit will be offered as Customer’s sole and exclusive remedy.

In a situation where Product(s) is ordered incorrectly or returned without a defect, Seller may at its discretion, accept the return of any such Product, subject to a 25% processing and restocking charge, plus any shipping, handling and packaging costs.

16. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, excluding any conflict-of-law provisions. The venue for any dispute hereunder shall be a court of competent jurisdiction located in Massachusetts. The parties acknowledge and agree that the United Nations Convention on Contracts for the International Sale of Goods is specifically excluded from application to the Terms.

17. Miscellaneous

If any term or provision of these Terms is invalid, illegal or unenforceable in any jurisdiction, any such term or provision shall be ineffective to the limited extent of such invalidity, illegality or unenforceability, without rendering invalid or unenforceable the remaining provisions of these Terms. If a court of competent jurisdiction declares any such term or provision to be invalid, illegal or unenforceable, the parties hereto shall request that such court reduce the scope, delete specific words or phrases from the term or provision, or replace the provision with a provision that is valid and enforceable and that comes closest to expressing the original intention of the parties hereto, and these Terms shall be enforceable as so modified in the court in which the provision was declared invalid or unenforceable. No waiver of a breach of any provision of these Terms shall constitute a waiver of any other breach, or of such provision. Seller shall not be responsible or liable for damages resulting from a failure or delay in its performance hereunder to the extent such delay is due any act or event beyond its reasonable control, whether or not foreseeable, including, without limitation, acts of God, fires, storms, earthquakes, floods, accidents, sabotage, embargoes, acts of terrorism, wars, riots, labor disputes or shortages, strikes, governmental laws, ordinances, orders, rules and regulations, shortages of or inabilities to obtain raw materials, supplies, utilities and equipment, failures or delays in transportation and any other similar or different contingencies. These Terms and the applicable Order constitute the entire agreement between the parties hereto with respect to subject matter hereof. By placing the Order, Customer waives all terms and conditions contained in its order acknowledgment form, purchase orders or other documents that are different from or additional to the terms and conditions set forth in these Terms, and all such different or additional terms and conditions shall be null and void. These Terms supersede all prior or simultaneous representations, discussions, negotiations, letters, proposals, agreements and understandings between the parties hereto with respect to the subject matter hereof and thereof, whether written or oral. The parties to these Terms are acting as independent contractors and nothing contained in these Terms shall be construed to place the parties in the relationship of employer and employee, partners, joint venturers, or principal and agent. Neither party shall have the right to act on behalf of nor bind the other except as expressly provided for in these Terms or as may be hereafter agreed in writing.

 18. Additional Terms Regarding Monomer and Tetramer Products

In addition to the terms and conditions set forth above, if Customer purchases or otherwise obtains from Seller any Products that are either a monomer or tetramer, the additional terms and conditions shall be considered part of these Terms:

a) Resale of the Products to any third party is strictly prohibited.

b) Seller’s monomer and tetramer Products are not intended for clinical diagnosis, prognosis, or therapeutic determinations. Customer represents and warrants that it shall use the monomer and tetramer Product(s) for in vitro research or investigation purposes only.

c) Seller’s obligation to manufacture and sell each Product is conditioned upon the satisfactory formation of the peptide (i.e., the string of amino acids associated with certain products) complex in sufficient quantity of the Product to deliver the quantity set forth in the Order and to allow Seller to perform quality control consistent with its standard quality control practices.

d) If the Order indicates that Seller will provide the peptide, Seller will be responsible for producing or obtaining the peptide. If the Order indicates that Customer will provide the Peptide:  (i) Customer will deliver the peptide to Seller in a timely manner and in the quantities and specifications that Seller reasonably may request; (ii) from time-to-time as required by Seller for Seller to meet its obligations under these Terms, Customer shall deliver further quantities of the peptides; (iii) there shall be no charge to Seller for the delivery to or the use by Seller of the peptides.

e) Customer hereby agrees to indemnify, defend and hold harmless Seller and its officers, directors, shareholders and employees, from and against any and all damages, liabilities, claims, demands, losses, costs and expenses (including without limitation reasonable attorney’s fees and disbursements and court costs) incurred in connection with damages, claims or suits, whether based in statute, contract, tort, strict liability or otherwise, to the extent arising from or relating to an assertion that the use of the peptides supplied under these Terms to Seller or the use of such peptides in the Product(s) constitutes an infringement of any patent or other intellectual property right or the unauthorized use of any third party trade secret.

f) In addition to any prices specified in an Order, Seller may apply a peptide acquisition fee if Customer requests that Seller provides the peptide. The peptide acquisition fee will be invoiced when the Product is shipped and is non-refundable, even if the Product (monomer/tetramer) manufacture fails.

g) In addition to any prices specified in an Order, Seller may apply a feasibility fee if the manufacture is attempted, but fails to generate the Product (monomer/tetramer).  If the manufacture is successful, the feasibility fee will be waived.
