In the sense of the quotes you copied. The first implies that there is no guaranty regarding the regional imprint a product might have (documentation, firmware language choices, etc.). It also implies that the warranty (if any) will be through the manufacturer.
The customs implications are pretty much standard for any off-shore seller, regardless of where the vendor is located. If you make a purchase outside your country, you are the importer and are responsible for any import duty.
