These Terms of Sale may not be altered, supplemented or amended by use or reference to any other documents or agreements, unless and except as expressly agreed by MWI in a mutually executed writing. Any Products sold under an agency model will be subject to the respective manufacturer’s terms of sale.

In addition, you will be liable and pay for any costs, including reasonable attorney and collection agency fees, incurred by MWI to collect any past due amounts. If you experience a change of control, become insolvent, are named in any legal, arbitration or other proceeding to collect money, or file bankruptcy, then all amounts you owe to MWI will become immediately due and payable. MWI may impose a surcharge on all statement balances paid by credit card.

13. Returns and conditions

MWI Animal Health provides you, our customers, with a generous returns policy for obtaining credit or adjustment for products sold by MWI Animal Health. Customers may easily request a return, credit or adjustment for eligible items purchased directly through MWI Animal Health by contacting our Customer Care Returns Department:

To initiate your return request, all returns must have prior authorization to ensure timely and accurate processing to your account. Customers will have 30 days to utilize the return authorization label we provide for your return through a UPS facility. Due to the nature of some items carried by MWI Animal Health, not all items qualify for return or credit.

You must notify MWI Animal Health within three business days of receipt of your order regarding any items that are damaged, shorted, mis-picked or ordered incorrectly for authorized return correction adjustments or such items will be ineligible for return and credit. If a reshipment or order correction is needed, reach out to your sales representative at 800.824.3703.

All other items may be returned only if they qualify as saleable product and will be subject to a restock fee. Saleable product is defined as product that:  i) is in the original, unaltered, unopened package with seals intact; ii) is free of markings, stickers and damage; iii) has at least 6 months dating remaining upon the date of receipt by MWI; iv) is returnable and saleable under applicable laws and regulations at the time of return; v) has been properly stored, handled, and shipped as to not affect the quality or efficacy of the item; vi) was purchased by you directly from MWI in the ordinary course of business; and vii) does not otherwise qualify as a non-returnable item. 

Restock fee will be based on your Invoice Date. You will have the following number of days to return your items to minimize applicable fees: i) within 60 days - NO restock fee; ii) 61-365 days - 20% restock fee; iii) after one (1) year items are non-returnable. 

The following items are non-returnable items and will not be accepted for return or credit: controlled substances; Rx labeled script items; items dropped shipped by the manufacturer or another third party; special or custom orders; open and used equipment; diagnostic test kits; refrigerated items (some exceptions may apply); hazardous materials; partials; discontinued or obsolete items; expired product or product approaching expiration; items not purchased directly from MWI; items purchased from MWI more than one year from the date of return; and items in unsaleable condition and outside of the initial reporting window for MWI caused damages and errors.

Class 2 and 2N controlled substances require MWI Animal Health to send you a DEA Form 222 to enclose with a pre-approved authorized return label. 

Exceptions may be administered for specific manufacturer’s return policies, subject to applicable restock fees.

All return authorizations must be signed to be valid for processing and by returning any product to MWI, you guarantee that such products were properly stored, handled and shipped as to not affect its quality or efficacy.

MWI Animal Health reserves the right to refuse and deny credit upon return receipt if item does not meet the requirements of this policy upon inspection. MWI Animal Health reserves the right to destroy all items that are not authorized or eligible for return and will not issue credit for such items.

Some jurisdictions do not allow the exclusion of implied warranties or limitations on applicable statutory rights of a consumer, so some of the above exclusions and limitations may not apply to you.

B. REMEDIES. Your exclusive remedy for breach of warranty is to return the nonconforming Products for a refund of the purchase price, repair or replacement. MWI has the exclusive right to select the remedy.

C. PAYMENT REQUIRED. MWI’s warranties are effective only if MWI has received payment in full for the Products.

15. Limitation of liability

MWI expressly excludes, and will not be liable for, any special, indirect, incidental, consequential, punitive or exemplary damages of any kind, including but not limited to, loss of profits and loss of or damage to animals or property, even if MWI has been advised of the possibility of such damages. MWI’s total liability to you for any claims of any kind related to any Products or MWI’s performance under these Terms of Sale, whether for breach of contract or warranty, strict liability, negligence or otherwise, shall be limited to direct monetary damages only and shall not exceed the purchase price of the Product at issue. Some jurisdictions do not allow the limitation of liability for personal injury, or of incidental or consequential damages, so some of these limitations may not apply to you.
