Import duty on personal postal and air imports revised for medicines and other goods, with higher duty for non medicinal items. The First Schedule to the Customs Tariff Act is amended by omitting specified column (5) entries in listed headings, substituting a linear metre duty entry for sub heading 37.01/08(2), substituting a new column (3) rate for Heading 100.01, and replacing Heading 100.02 with a provision applying to dutiable articles for personal use imported by post or air (excluding Heading 100.01 and alcoholic drinks), separating drugs and medicines from other personal imports for distinct duty treatment.
