To import one address from wallet A to wallet B (different softwares) you need to check wallet B supports the BIP used by wallet A or not.
What?
OP wants to import a
single private key into a different wallet.
This has nothing to do with the mnemonic codes and seeds you probably are referring to with "BIP" (BIP39).
Sweep is another way to move your bitcoin from wallet A to wallet B.
And OP explicitly mentioned he does not want to sweep his coins (which creates a transaction) but just wants to import the private key.
When importing a key, the coins are not moved. You'll just gain the possibility to move your coins with another software.
