How to check where an Etsy order will ship from before you buy
A shop's location and a parcel's origin are two different facts, and Etsy only shows you one of them. The storefront says where the seller is. Nothing on the page says where the box starts its journey.
Four ways to find out before you pay
The delivery estimate
Open the shipping section on the listing and read the window for your own address. A small item moving inside one country arrives in a few days. A window of two to four weeks on a keyring means a longer trip than the storefront implies, whatever the storefront says.
The reviews, searched for one word
Search the shop's reviews for customs. Buyers who paid an unexpected import charge always mention it, and they name the country on the label while they are at it. One review saying the package came from China tells you more than the whole storefront does.
The shipping profile
Some listings show a ships from line under the delivery estimate. Where it exists it is the seller's own declaration and it is the best answer on the page. Where it is missing, the seller has not been asked to give one.
Just ask
Message the shop and ask which country the parcel ships from. It is a plain question with a one word answer, you get it in writing before you pay, and a shop that will not answer it has answered it.
Why this is worth a minute
Import charges land on you and not the seller. Returns to another continent cost more than the item. And a shop naming one country while posting from another has told you it will describe other things loosely too.
We record both figures for every shop we read, the place it claims and the place buyers say the parcel came from. Where those two disagree is a page. Shipping from anywhere is fine. Saying one thing and doing another is the part we write down.
