Whether it is applicable in India or it is an International standard?

That is not entirely true, I have a ceiling fan that can also run in the opposite direction, to reverse the flow of air.
That said, for most fans, it is presumably a lot easier to have them all rotate in the same direction, as it simplifies the design of the electric motor from various suppliers.

All the fans in my house can be switched to turn either CW or CCW. That is to permit the air flow to be reversed in winter so that warm air does not stagnate at the top of the room.
However, there is no compelling reason for the convention you are stating. They could rotate in the other direction and STILL blow air downwards if the blades were pitched accordingly.
There is, however, a convention for direction of propeller rotation on planes in the USA. It is always CCW as seen by an observer standing in front of the plane.

Most ceiling fans I've installed are reversable. Try looking at some different fans - it could be the one you're looking at is simply an optical illusion caused perhaps by the lighting (stobe effect) or maybe it only has one direction. Ceiling fans certainly don't have an international standard for rotational direction.

It's because your in India. In America, our ceiling fans have a switch on them that let the fan rotate in both directions. Typically you run clockwise to blow air down in the summer and counter clockwise to blow air up in the winter.

Ceiling fans DO NOT rotate clockwise...until you flip the switch to change the direction.

Well this is not entirely true, you can get fans (most ceiling fans) that have a switch on them to make them go in reverse, instead of blowing air down, it sucks it up.

Some manufacturer design and engineer their fan from the top to bottom.

if you flip the direction switch it goes the other way.
it would not be for me to be saying how that it is happening in India.

if you adjust it...it will rotate the opposite direction also...
one is for cooler temps...and the other for warmer temps...

most have a button that will change the direction
