IoTaWatt, Inc is a US company. The units are manufactured and shipped from it’s northeast location in scenic New Hampshire. We use the various services of the United States Postal Service, which in our opinion maintain the most reliable and economical network for this scale of business.


Shipping within the 50 US states is free for orders of $100 or more. All orders are shipped USPS Priority Mail with service from 1-3 days depending on distance and time-of-week. For orders less than $100, or those preferring to use Priority Mail Express, we charge the USPS retail rate with no additional fees.

Next day service is also available with UPS next day air.


For our northern neighbor favorable rates are available. We offer a flat-rate of $20 for packages up to 4 lbs. USPS First-Class International is used and the package typically arrives by Canada Post within 1-2 weeks. Where you don’t see that offered in checkout, the weight exceeds 4 lbs.

USPS Priority International is also available packages above 4lb or when faster delivery is desired.



Worldwide, the USPS maintains relationships with the national postal service in many destination countries and we accept orders from those countries. Orders are sent out using a commercial equivalent of First Class International. The official time frame is 1-3 weeks. Lately, shipments are running about 2 weeks. All orders have tracking numbers, however the details supplied by individual destination countries varies greatly, and see “Duties and Taxes” below.

The magic number with international shipping is 4 lbs (1.8kg). Rates increase dramatically after that. As such, we offer low flat rates below 4 lbs. Sometimes it may be advantageous to break up a larger order into two smaller orders. The shipping calculator in the shopping cart is helpful in making that decision.

0-2 lbs – $15 US, 2-4 lbs – $25 US


For packages exceeding 4lb or where faster delivery is desired, USPS Priority Mail International and Priority express international is available.

We’ve elected to discontinue offering UPS service as UPS base rates are about the same as USPS and UPS charges recipients an additional $50+ for “Processing Fees” in addition to the duties and taxes.

Duties and Taxes

IoTaWatt does not collect destination duties or taxes. We have enough experience with our own imports to appreciate how complex that can be. Destination postal services have infrastructure in place to collect whatever is due. We include the appropriate customs declarations with each international shipment. Each country has their own methods and procedures for notification and collection. It’s up to the individual recipient to contact their local postal service with the tracking number if there is a suspected delay or lost notification.
