Yes the rule is always that, if I'm not mistaken, it applies to any post office in the world. Only that Poslaju or Pos Malaysia rarely enforce it. It depends on your luck too. They might use volumetric weight if the shape of ur parcel is very irregular, like a poster tube (you know la if send a piece of poster, the real weight might be very light, hence the volumetric weight applies).

Generally volumetric weight is heavier than actual, but not necessarily. They will use whichever is heavier. The rate is same, so it will be more expensive if ur volumetric weight is heavier than actual. Or vice versa. 

Formula to calculate: (Length x Width x Height in cm) / 6000 = volumetric weight in kg.

Owhh, didn't know that. Yeah more profit for them then  .

I guess Pos Malaysia/Poslaju still divide by 6000.

if you're a regular you can request for 6000...

or you can send via poslaju hahaha

they will compare the vol. weight and actual weight and choose the heavier one to bill you

if the parcel is heavy enough, of course they wont waste their time to measure the dimension

what's up, pos malaysia still uses 6000?
