Order Processing

Most orders are processed the same or next business day. While we are fast in processing, regrettably we cannot guarantee a particular processing time for your order.

As a high volume shipper, we have well-established relationships with USPS, FedEx, and UPS and offer our commercial rates to you! The quoted shipping cost is based on dimensional weight. A signature may be required upon delivery at our discretion.

On average, you can expect your order to be delivered within 4-7 days from the date of shipment (not necessarily the date of your order); however this may vary due to your location in relation to our warehouse and the shipping method chosen. Please note due to special handling requirements, shipments containing UN3480 class Lithium-ion Batteries may take longer for delivery than normal products.

Please understand carrier delays are not within our control and we cannot make any guarantees for a particular date of delivery. Any such guarantees for overnight, 2nd day, and other services are from the logistics company only. Please note Saturday and Sunday are not considered business days and delivery will not be made on the weekend from UPS or FedEx even for 2nd day or overnight services - for example an overnight order shipped on Friday would be delivered Monday, not Saturday. USPS does not offer guaranteed delivery dates for any services they offer.

Our cutoff time for same-day processing of express orders with UPS & FedEx is 12pm CST. Please note USPS Priority mail is not considered express service and such orders are not expedited through order queue.

Please note FedEx and UPS do not deliver to PO Boxes. If UPS/FedEx is chosen for the method of delivery with a PO Box as the address, the shipping method will be changed to USPS. IMR Batteries may, at its discretion, change the selected shipping method for any order without prior notice.


International Shipping

Please understand transit and customs delays are not within our control. The quoted shipping cost is for delivery to the destination address only. The receiver (importer) of the package assumes any and all obligations to pay applicable duties, fees, taxes, etc assessed to the order by the shipping carrier and/or governmental authority.

It is the receiver's responsibility to know and understand their country's laws and regulations regarding imports. IMR Batteries will not be responsible for shipments withheld or seized by Customs in the destination country. IMR Batteries will not modify the prices paid for goods purchased on a commercial invoice for any reason.

If you are located outside of USA/Canada and would like to place an order for lithium-ion batteries, we suggest using a freight forwarder in the US who can arrange for international HAZMAT shipping and customs clearance on your behalf. We plan to offer HAZMAT air shipping to international destinations in the near future.


Refused/Return to Sender/Undeliverable Shipments

If an order is refused, marked return to sender, or deemed undeliverable by the carrier due to an incorrect address or otherwise, the customer will receive a refund for the purchase price of the products less a 20% restocking fee as well as any applicable return shipping fees assessed to the parcel by the shipping carrier. USPS First Class Mail & USPS Priority include free return shipping for refused packages while USPS Parcel Select, UPS, and FedEx services are assessed return shipping costs by the respective carrier. An applicable refund will be processed once the package has been received at our facility. The original outbound shipping cost is nonrefundable.


Misdelivered Shipments

Online tracking delivery confirmation from the carrier is considered proof of delivery. If tracking shows delivery confirmation and you did not receive the package, we will initiate an investigation with the carrier on your behalf. Rest assured if the carrier confirms mis-delivery and cannot recover the package, we will provide a full refund, inclusive of shipping costs, to the original payment method.

IMR Batteries, however, will not be responsible for package theft once delivery is complete. It is the responsibility of the receiver to have a secure location for package delivery. If you would like to request a signature for your order upon delivery, please write a note for us in the comments section when placing your order and we are happy to oblige.

If you believe your package was stolen we suggest filing a police report. If the shipment was with USPS, we also suggest filing a mail theft report with the US Postal Inspection Service as stealing US Mail is a federal offense.


Lost Shipments

If a shipment is lost by the shipping carrier, IMR Batteries will provide a full refund, inclusive of shipping costs, to the customer's original payment method. Domestic USPS (48 US states) shipments are considered lost after 30 business days from the last tracking scan/entry. USPS shipments to US territories or international destinations are considered lost after 60 business days from the last tracking scan/entry. An international shipment is not considered lost if Customs in the destination country has withheld or confiscated the shipment. FedEx or UPS orders are considered lost once FedEx/UPS has confirmed such in writing after a trace/investigation has been performed. If you believe your order has been lost by the shipping carrier, please contact us and we will work with the carrier directly on your behalf for a resolution.
