Consequential amendments to tax law redefine 'new machinery' and 'new ship or aircraft', conditioning depreciation eligibility on prior use and importation.

Consequential amendments revise definitions and cross references in the Income tax Act to align depreciation and deduction provisions: new ship or new aircraft is extended to previously used assets not earlier owned by a resident in India, and new machinery or plant includes machinery used abroad if not previously used in India, imported, and not previously allowed depreciation; multiple clauses and sub sections are substituted or omitted to narrow qualifying references and redirect explanatory cross references.
