Those who purchased local stamps and local registered labels (red) will still be using the SAME postage rates EXCEPT there is an additional 6 % added to the purchase from 01 October 2016.
Thus the commemorative stamps and local definitive stamps can still be used as postage to international destinations as well as domestic use.
The new additions are the International Definitive Stamps without GST. The postage rates to international destinations remain unchanged.
Thus to keep a postal history first day of usage cover, you might want to send a letter overseas. If the cost is, e.g. RM 2 to Europe, just put a philatelic stamp (from sheet of 10) and a normal stamp (from the sheet of 100) of RM 1 each with their margins intact. The margins are the easiest way to differentiate the different versions. There is no need to put the normal local postage stamps as the validity of local stamps is unchanged. You just want to record the changes. Here is an example.
Start to prepare your postal covers.
01 Octobet: First day of usage at selected post offices nationwide.
03 October: First day of usage in Kedah, Kelantan, Terengganu and Johor.
04 October: First day of usage in the rest of the country.
