Lubricating preparations not based on petroleum oils
HSN 3403 99 00 (other lubricating preparations not containing 70% or more petroleum oils or bituminous-mineral oils by weight) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Lubricating preparations with a petroleum-oil base exceeding 70% by weight are classified under a sibling tariff line within Chapter 34 that may attract distinct compliance.
The principal importer risk at this tariff line is misclassification: if the preparation's petroleum-oil or bituminous-mineral-oil content meets or exceeds 70% by weight, customs may re-classify it to the petroleum-based lubricants line, triggering retrospective duty recovery and potential detention. Product formulations that double as textile, leather, or furskin treatment agents should also be verified against their intended-use classification, as Chapter 38 covers certain chemical preparations for industrial use with overlapping scope. Retain laboratory composition certificates and technical data sheets to defend the classification on examination.
