Malaysia: Postage Due Aerogramme

Malaysian aerogramme (Wiegand #14, imprinted "Security Printers Malaysia" on bottom) sent from Sungai Petani (5 MEI 1982) to London, UK. At the time of posting, the aerogramme rate was 40 cent. Hence, the aerogramme was short paid by 10 cent.

The Malaysian postal clerk applied a triangular "T" handstamp and endorsed the tax fraction "20 / 40" in red. Double the deficiency in the numerator, however, was the rule of taxation established at the 1964 Vienna UPU congress, which had already been abolished by the decisions of the 1974 Lausanne UPU Congress. The new regulations, which came into effect on January 1, 1976, stipulated that single deficiency has to be noted as the tax fraction's numerator.

In the UK, a green boxed "To pay" handstamp was applied and a postage due of "29 p" was endorsed. The UPU letter rate of the UK was 19 ½ p. So, the postage due was 20 / 40 x 19 ½ p = 9.75 p, which was rounded down to 9 p, plus a fixed surcharging fee of 20 p for a total of 29 p.

The payment of this amount is documented by four postage due stamps with a total face value of 29 p.
