 Shipping & Returns


Univair charges ACTUAL SHIPPING COSTS on all shipments.

  • The shipping charges added to your order during the checkout process are a MINIMUM ESTIMATE for the type of delivery service you choose (Standard Ground, Express, Priority, Overnight, etc.). Actual charges may be more depending on delivery address, package size, number of packages, etc. In some instances, delivery charges may be less than the minimum estimate shown. We will adjust (plus or minus) the final shipping costs on your credit card/PayPal account when your order ships.

  • Some orders may require multiple shipments because of the size, weight, and/or quantities of items ordered. You will be charged actual shipping costs on ALL packages.

  • Univair reserves the right to add additional charges to your order for oversize items, hazardous materials, crating charges, international deliveries, multiple shipments, trucking fees, and any other fees imposed by the shipper.

  • If you need to know exact shipping charges prior to submitting your order, please contact a Univair representative at our toll free number 888-433-5433 during regular business hours for an estimate. Please note that in most cases, exact shipping costs cannot be calculated until your order is packaged and ready to ship, since shipping costs are based on size, weight, and number of packages in your order.


  • All items returned to Univair for a refund or credit must be authorized in advance. There will be a 10% restock charge assessed if it is determined that Univair is not at fault. If you received an item that you wish to return, please contact us immediately at 303-375-8882 for a return authorization.
