Tariff classification amendment revises two customs notifications to expand and specify covered imported goods entries. The Government amends two customs exemption notifications to change tariff references and item descriptions: in Notification No.25/99 Customs, List A at S. No.87 column (2) '73' is replaced by '72 or 73' to broaden tariff coverage; in Notification No.19/2000 Customs, the Table at S. No.33 is amended to substitute a specific entry describing populated printed circuit boards and accessories of machines, clarifying their inclusion under the notification.
