My GF was delivered on Tuesday morning to Ogdensburg, NY. I brought it across the border Tuesday afternoon.
It went very smoothly.
I used a service called MyUSaddress.com. They provide you with a free U.S. address. They charge you $5 per package, and you have one year to pick it up. It was a 2 minute drive from the border to their warehouse. The staff gave me my packages and in about 10 minutes, I was back on the road heading to Ottawa.
I told the border agent that I purchased a laser-cutter, and what it was worth. He asked a few other questions (firearms, tobacco, etc.), and then gave me a declaration paper to bring into the building to pay my taxes.
I went in. I talked to another agent, and it took a little while to explain what it was. Luckily, based on a tip from @SunnyStarbucks, I printed a screenshot of the GF front page that shows what you can make with it. I also had a copy of the user manual.
I also printed a copy of my paypal receipt, and a copy of the “here’s what you purchased” page from GlowForge.
I think his biggest concern was whether I was allowed to bring this into the country. I told him I shipped it to the US to save on shipping costs. He asked if they would ship it to Canada, and I said that yes, shipping to Canada was available for a higher cost. That put him at ease.
I had printed proof that it was manufactured in the states, but he did not ask about it. It also says it prominently on the box, so you don’t have to bring that proof.
Once he determined that I was allowed to bring it in. He printed a page with an amount of tax to pay. I brought it to another agent, and paid the taxes on it. It was about $570 if I recall correctly (I left the receipt at home).
I then drove away, got home, and starting making things!
So in summary, bring:
-Your receipt from Credit Card or Paypal
-Your “what you purchased” page from GF.
-Some way to show what the GF does, so you can easily explain it.
Let me know if you have any questions. I’m happy to help out.
