amendments to existing legislation on Friday.

In addition to changes to the Post Office Regulations, legislation will cover mammography testing and Marine and Ports' discharge book purchases.

Overseas mailing costs will rise across the board, including International Data Express (IDE) and air mail.

Sending a package to the US and Canada via IDE, for example, will now be $25 up to a half of a kilogramme and $3 for every 250 grams above that.

Sending to the UK will now be $30 and the cost to other parts of the world vary from $25 to $35.

The minimal cost to send letters and postcards via airmail will be 70 cents.

The cost of sending a parcel to the US is $7.65 if it does not exceed 500 grams.

The Public Health (Diagnostic Facilities) (Mammography) Regulations will allow for the registration of the businesses and people that test for breast cancer in women and men.

Like other legislation that governs the registration of medical doctors, nurses and other specialists, the regulations require the Chief Medical Officer to hold the registration records.

And with the passage of the Merchant Shipping (Fees) Amendment Regulations, a discharge book will now cost $50.
