They are selling them without PFC because you may not need it!
You need to study BS EN 61000-3-2 with all its amendments, particularly
the Millennium Amendment.
OK, the safety standard for the Low Voltage Directive is BS EN
For EMC, there are four standards:
BS EN 55014-1: 1997 or 2001, for high-frequency emissions. The 1997
edition can still be used, but for new products the later version should
BS EN 55014-2:1997 for immunity.
BS EN 61000-3-2:1995 with all amendments or 2001 for mains harmonic
BS EN 61000-3-3: 1995 with amendment 1 for voltage changes impressed on
the mains supply.
