TRAX machines are duty-free into the USA under the United States-Mexico-Canada Agreement (USMCA). You won’t pay duty on them.
For US shipments over $2,500 USD, US Customs (CBP) needs to know who is importing the goods. That’s you, so you need a CBP importer number. You get one by sending CBP a Form 5106. It’s free, and once you have a number you can use it again for future orders.
Already have an importer number? Enter it at checkout, or send it to us with your order number. You can skip the steps below.
How to get your importer number
- Install or update the free Adobe Acrobat Reader. CBP only accepts the form signed digitally, not printed and signed by hand.
- Download CBP Form 5106 from cbp.gov. If the page shows “Please wait…”, right-click the link and choose “Save link as” to save the PDF to your computer.
- Open the PDF in Adobe Acrobat Reader, fill it in and sign it electronically.
- Email the signed form to CBP at CEE-Machinery@cbp.dhs.gov.
- CBP emails you back a confirmation with your importer number.
- Send us that confirmation and number by replying to your order email.
Use exactly the same name and address as on your TRAX order. If anything is spelled differently, CBP and our customs broker can’t match the shipment, and it can be held at the border, with storage fees, until it’s fixed.

Due to the fact that the TRAX J5 is a large item and that we need to ship LTL freight we will need to get a rate quote for shipping to your location.
