Countries outside the "single market" sell into it all the time.

Of course they do, but have to deal with tariffs and quotas.

Unless they sign a free trade agreement. The EU has FTAs with many
countries which do not involve
adhering to the EU's single market rules.

But that trade involves a lot more paperwork than trade within the single
market. So, although there aren't tariffs, the trade isn't frictionless.
