UK: 1960 Aerogramme Form Taxed and Diverted to Surface Mail

Franked at 3d and sent to Farmington (Connecticut), US, from Peckham (25 FEB 1960).

Country of destination: Postage due handstamp „Due 7 cents“ applied in the US. Postage due converted at a rate of 3 UPU centimes = 1 cent.

1957 Ottawa UPU Convention: „Items of air-mail correspondence on which the charges paid do not represent at least the amount of the air surcharge or, as the case may be, 75 per cent of the air surcharge or the combined charge, are treated in accordance with Articles 52 and 55 of the Convention.“ (Provisions Concerning Air Mails, Article 6)

Trinidad & Tobago: Aerogramme Posted Underpaid Twice

20c aerogramme returned for additional postage, but posted underpaid a second time and sent to Pakistan on 17 March 1976. The aerogramme was initially returned to the sender for paying the missing 5c to the 25c aerogramme rate for Pakistan. Endorsed „Returned for 5c … postage“. However, the sender did not pay the additional postage and posted the underpaid aerogramme a second time.

As the aerogramme was only prepaid at 20c, it was taxed „10/15“ (double deficiency as the numerator, international surface mail rate as the denominator according to the Vienna system) when posted the second time. This is incorrect as the Lausanne system, which required the single deficiency in the numerator, was in place since 1 January 1976.
 
In Pakistan, based on the „10/15“ tax fraction a postage due of Rs 17 was calculated.
