Planning a short cruise, Vancouver to San Diego with a stop in Astoria, OR. My question is how does one treat good bought in OR while on shore, then brought back to the ship when you go through US Customs.
Declare? If you have receipts to show you bought in USA and you never disembarked with the goods in the foreign port why declare?
OR, not declare and then have to argue with the agent if she looks at luggage?

My feeling it that is purchased and therefore not part of your duty free allowance. But....

That should have read is US purchased...

I think you are allowed $400.00 duty free. If all you are bringing in is souvenirs I would not declare anything. I usually list a number below that as that's all I have. US customs isn't concerned with small stuff. They are looking for contraband, drugs, and so on. I would not worry about.

If you are US citizen returning to US, what you need to declare is what you have purchased in Canada, plus duty free items bought on the ship or elsewhere.

You don't have to do anything about goods bought in Oregon. No declaration, no nothing. Just keep receipts for any large purchases in case there is a question. Only declare goods bought in Canada.

Doug ... duty free items bought on the ship should be declared as well, especially liquor and tobbaco.

As to non-duty free items bought on the ship, they should be declared as well as the shops operates in "high sea" which is considered not within the US as the ship does not charge any state or local tax.
