Shipping & Returns


Our first concern is to fill orders accurately and quickly. While we make every effort to ship on a same day basis for orders called in by 2:00 PM EST, this is not always possible. If order is required by a specific date, please inform our customer service / order department, and we will give you an estimate of ship date. 


1.Parts returned must have a Return Merchandise Number Authorization (RMA). Call to obtain RMA # prior to shipping. Reference RMA # on return shipping box.
2.Enclose copy of invoice.
3.Parts must be returned undamaged and in perfect condition that may be resold as new within 30 days of original purchase date to receive full refund or credit. Refund or Credit will be issued only upon inspection of returned part’s condition.
4.Returned Merchandise received after 30 days from original invoice date are subject to approval and will incur a 15% handling and restocking fee.
5.Special order items and parts made to order or cut to length can not be returned.
6.Shipping charges must be prepaid.
7.Return shipments to Signal Dynamics Corp. should be returned to 150 Hilden Road Suite 312, Ponte Vedra, FL 32081


Every effort is made to correctly invoice and ship part(s) specified by customer. Shipping errors are kept to a minimum by maintaining strict quality control maintained by double inspection of all orders shipped. If a shipment is received containing an incorrect part(s):
1.Immediately notify customer service of error at 904 342-4008.
2.RMA number will be issued for the return of Incorrect part(s) – see Return Merchandise policy
3.If exchange part is required prior to return of incorrect part(s), customer will be charged and credit will be issued upon return of part to SDC.
4.Replacement parts are shipped First Class Mail only. If customer requests expedited service, difference of standard versus expedited shipping fee will be charged to customer.
5.If exchange part is backordered, customer has the option of waiting for backordered item or requesting refund. Refund or Credit is issued when undamaged and packaged part is received by SDC.
Questions regarding returns, credits, billing/shipping errors should be directed to Customer Service Department at (800) 785-1814.


Shipments via United States Postal Service (USPS) can ship out same day before 12pm (noon) Eastern Standard Time (barring any items that may be backordered). Saturdays do constitute "business days" per USPS.com when calculating shipping times. Shipments via United Parcel Service (UPS) can ship out same day before 2pm Eastern Standard Time (barring any items that may be backordered). Unfortunately, we DO NOT offer UPS Saturday Delivery due to cost of delivery. UPS DOES NOT consider Saturdays to be apart of their "normal" delivery time.


All orders are packaged with great care. However, if order is received from UPS in damaged condition, please report this information to UPS at (800) 742-5877 prior to notifying us. UPS must see damaged package to inspect for claims purposes. If package is received from any other shipping source or post office, contact us at 904 342-4008. Please have your invoice number available for reference.


Any errors in shipments must be reported within five (5) days of receipt of order. All orders are packaged with quality control management. Failure to make claims for shortages within 5 days of receipt of parts will result in ineligibility for remedy and customer will be liable for invoiced charges.


Signal Dynamics Corporation is the manufacturer /distributor of BackOFF™ products and accessories. Refer to each part for the warranty guidelines of that individual part. All decisions regarding the repair or replacement of the item are the sole responsibility of SDC.
