No. Metzee is an India marketplace, and it is India all the way down rather than India-first.
Worth saying plainly so you do not plan around something that is not there.
Where it shows
Addresses are Indian. The address a buyer saves is house and street, city, state and PIN code. There is no country field, because there is only one country.
Delivery is priced by PIN code. Your zones are built from PIN codes, districts or a radius, and the courier quotes against an Indian PIN. There is nothing to quote against abroad.
Payment is in rupees, through an Indian payment provider.
Tax is Indian. Every seller needs a GSTIN or an ECO enrolment number, and the marketplace deductions are Indian ones. Do I need to charge GST on what I sell?
So this is not a setting waiting to be switched on. It is the shape of the thing.
What about a buyer abroad who wants your item
They can watch, and some do. What they cannot do is give you an address the system can price or a courier can reach.
Arranging it privately is not the answer: a sale moved off Metzee to avoid that loses every protection for both of you, and moving a sale off the platform is on the not-allowed list. The honest answer to a buyer abroad is that you cannot post to them from here. Is Metzee safe to buy from?
Why build it this way
Because a marketplace that serves one country properly is more useful than one that half-serves several. Delivery, tax, payment and language are all local problems, and solving them for India meant solving them specifically — twelve languages, PIN-code zones, volumetric weight, GST-inclusive prices, an enrolment route for sellers without GST.
Every one of those would have been watered down by a country selector.
What India already gives you
A large market, and one you can sell into from anywhere in it. A store in a small town reaches the same buyers as one in a metro — the live show does not know where you are. Selling from a small town
If you already export
Keep doing it however you do it. Metzee is a channel for your Indian sales, not a replacement for the rest of your business.
