Imported petroleum product: partial testing and non categorical reports cannot sustain classification as high speed diesel under tariff rules.
Classification requires evidence addressing all IS 1460:2005 parameters or, where full conformity is lacking, a Rule 4 "most akin" analysis showing closest resemblance among candidate headings based on reliable, reasoned laboratory results and expert opinion; partial testing or non categorical reports do not suffice to support penal or confiscatory measures.
