Customs tariff amendments redefine flash point and classification tests and revise duty entries across multiple headings.

Amendments to the Customs Tariff Act revise technical classification tests by requiring flash point determination under the Petroleum Act and authorise government notification for carbon residue and colour comparison test methods; they alter flash point and smoke point thresholds and related clause criteria in Heading No. 27.10, substitute duty-rate entries across multiple headings, add a new sub heading for aniline with a duty, and standardise entries for Heading No. 12 in the Second Schedule.
