Shipping:

Q:  Where will my order ship from and why is the shipping so expensive? 
A:  Prizmatix systems will ship directly from the Prizmatix production facility in Israel. Prizmatix ships FedEx International Priority and orders will generally arrive within 3-4 days of shipping. Imports into the USA are generally duty free and there is no sales tax. Shipments containing LED light sources are often subject to a $20-30 FDA fee to review the allow the shipment to enter the country. This fee is invoiced by FedEx and passed on to the FDA.

The shipping fee covers shipping only. Any import fees, customs if applicable are the customers responsibility. FedEx Trade Networks is the default customs broker for incoming FedEx shipments and does not charge brokerage fees. 

Prizmatix can also ship with your FedEx or UPS account. Please note that shipping charges on your account may be significantly higher than our ship by weight charge. See more below.

Fiber optics supplies and some accessories are usually in stock and ship from our US office. Chat with us to determine if the USA office has what you need in stock.

Q:  Can you ship using my FedEx or UPS account? 
A:  Yes. For complete systems and custom fiberoptics shipping from Israel, this is not recommended as prepaid shipping charges will be much less costly.

To ship on your own account; Choose Ship on Customer Account as the shipping method. Put your shipping account information and service level in the order comments. Prizmatix will ship international priority if you do not specify any other level. Please note that shipping charges on your account may be significantly higher than our ship by weight charge.

Customs and Tariffs:

Q: What tariffs apply to equipment and systems shipped from Israel?
A: Equipment and systems manufactured by Prizmatix or Lumiworks in Israel and shipped directly to customers in the U.S. are subject to a 10% customs tariff, as part of the U.S. tariff policy on Israeli imports effective April 5, 2025. Some items may incur additional customs charges depending on their classification. Please contact us before ordering to clarify specific charges for your order.

Q: Are there additional fees for LEDs in my order?
A: Yes, LEDs shipped from Israel are subject to an FDA review charge of $27.50 per order, in addition to the 10% tariff and any applicable customs charges. This fee is required for regulatory compliance in the U.S. Contact us to confirm if your order includes LEDs and to discuss these charges.

Q: Which items are exempt from tariffs and customs charges?

These items are ready for prompt delivery without additional fees.

Q: Will large fiberoptic orders incur tariffs?
A: Large fiberoptic orders may ship directly from Israel due to inventory requirements. These shipments will be subject to the 10% tariff and potential additional customs charges. We recommend contacting us prior to placing your order to confirm shipping details and associated costs.
