Shipments and returns

Your shipment

At this time, CTS Engineering ships merchandise to locations within the United States and U.S. territories, including Alaska, Hawaii. The risk of loss and title for all merchandise ordered on this Web site pass to you when the merchandise is delivered to the shipping carrier.

Packages are generally dispatched within 2 days after receipt of payment and are shipped via UPS with tracking and drop-off without signature. If you prefer delivery by UPS Extra with required signature, an additional cost will be applied, so please contact us before choosing this method. Whichever shipment choice you make, we will provide you with a link to track your package online.


CTS Engineering prides itself on being low cost on shipping.  We do not want to charge more than is required to ship your items. CTS Engineering only uses USPS Priority Mail Flat rate boxes.  Below is a fee table and details:

  • Small USPS Priority Mail Flat Rate Box: 8-5/8" x 5-3/8" x 1-5/8" - $5.80
  • Medium USPS Priority Mail Flat Rate Box:  11" x 8-1/2" x 5-1/2" - $12.35
  • Large USPS Priority Mail Flat Rate Box: 12" x 12" x 5-1/2" - $17.45

Due to limitations in the shopping cart shipping module, orders which will not fit into a single box will display only one shipping option "Shipping invoiced separately, to provide lowest available rates" with a $17.46 charge (largest box plus a penny).  However this is not your final shipping cost, as more boxes may be needed to fulfill your shipment. Additional shipping costs will be invoiced to you.

To avoid separate invoicing, please split your orders up where the cart shows only the flat rate box, not the "Shipping invoiced separately, to provide lowest available rates" message.

Every order is reviewed for accuracy. A refund of the difference will be issued if the cart overcharged you, based on the table above and number of boxes used to fulfill your order. Sorry for this inconvenience and confusion.
