Customer is responsible for paying all Taxes or other charges imposed by law with respect to the import, export, sale or use of the Products or Services purchased hereunder. If Jackson has a legal obligation to pay or collect Taxes for which Customer is responsible under this section, Jackson will invoice Customer and Customer will pay that amount unless Customer provides Jackson with a valid exemption certificate authorized by the appropriate taxing authority. The Parties will work together to avoid any withholding Tax if exemptions, or a reduced domestic or treaty withholding rate, are available. If Jackson qualifies for a Tax exemption, or a reduced treaty withholding rate, Jackson will provide Customer with reasonable documentary proof. Customer will make commercially reasonable efforts to notify Jackson of any withholding Taxes against payment to Jackson sufficiently in advance so as to allow Jackson to provide or apply for any eligible withholding tax exemptions prior to remittance. In the event that Customer must withhold any Taxes prior to remittance, Customer will provide Jackson reasonable evidence that it has paid the relevant authority for the sum withheld or deducted.The Parties agree to cooperate with each other on Tax matters.

Customer will not without the prior written consent of Jackson return Products or shipping containers to Jackson.


(12) Customer Materials

12.1 Customer will provide Jackson with sufficient amounts of compounds, materials, animals, substances, devices, and protocols meeting relevant specifications, including health and genetic data (“Customer Materials”) with which to perform the Services. Customer will provide Jackson with complete and accurate data to inform Jackson of the identity, strength, purity, stability, composition or other characteristics, proper storage, and safe handling requirements of the Customer Materials, including a material safety data sheet or equivalent documentation. All costs associated with shipping the Customer Materials to Jackson will be the responsibility of Customer.

Customer shall visually inspect the Products upon delivery. Health or quality control issues which can be noted upon visual inspection shall be reported to Jackson in writing within three (3) business days following delivery of the Products. In the event Customer submits written notice of health or quality control problems to Jackson within three (3) business days following delivery, Jackson’s policy on credits for live Mice shall apply. If no written notice of health or quality control problems is received by Jackson within three (3) days of delivery, then the Products will be deemed accepted in terms of health and quality control issues that can be observed upon visual inspection.

16.2 Jackson has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of Mice strains as well as the genotypes of strains with identified molecular mutations. The phenotype of each strain, however, may not be fully characterized or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all Customer expectations. To ensure that Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, Jackson recommends ordering and performing tests on a small number of Mice to determine suitability for your particular project.
