IMERC State Restrictions'
Due to mercury-added products being banned or phased out in some states, MDI cannot ship Mercury added products (Relays, Switches and Floats) to the following IMERC states:
Connecticut (CT), Minnesota (MN), Maine (ME), Massachusetts (MA), New Hampshire (NH), New York (NY), Rhode Island (RI), or Vermont (VT)
These states belong to the Interstate Mercury Education and Reduction Clearinghouse (IMERC) group, which have these restrictions.
Exemptions are currently being applied for in cases where Mercury Relays and Switches are being used to replace relays and switches in equipment originally manufactured with Mercury Relays and Switches. But, currently, MDI cannot ship into these states.

Back Ordered Items
After your initial shipment of in stock items are sent, all remaining back ordered items are shipped free of charge. If all items are out of stock when you submit your order, you are responsible for the initial shipping charge. If we receive a portion of the order we will ship those items at the original cost of shipping and the remaining back ordered items will ship at no cost to you.
The method of shipping will depend on the best option available. Back ordered items will ship either First Class Mail or UPS Ground. If you would like your back ordered items to be sent out using a specific shipping method you will need to contact us at (800) 634-4077. You will be charged for the cost of shipping your back ordered items if any other method is chosen. Typically, back ordered items, if not sent out the same day, will go out the following day. Travel time will depend on your location within the continental US. Please be advised, unless otherwise notified all back ordered items will be sent via First Class Mail or UPS Ground.
Back ordered items will ship out once they are in stock.
Made to Ordered Items
