Import dutyOK
- About ₹21,240 duty on every ₹1,00,000 of import value (CIF).
- No tariff line names this chemical, so we worked out its likely heading from its structure: 2901, acyclic hydrocarbons (hydrocarbon).
- All lines under heading 2901 pay basic customs duty 2.5%; with social welfare surcharge and IGST 18% that makes about 21.24%.
- Confirm the exact 8-digit code with your customs broker before you import.
SafetySTOP
- Catches fire easily
- Can cause long-term health damage
- Extremely flammable liquid and vapor
- Suspected of causing genetic defects
- May cause cancer

- Always read the supplier’s safety data sheet (SDS) before handling.
Storage, transport & PESOCHECK
- Petroleum Class A (flash point about -54 °C): importing, storing or transporting it above the exempted quantity needs a PESO licence.
- Ships as UN 1218 (Flammable Liquid): dangerous-goods rules apply by road, sea (IMDG) and air (IATA), with labels, packaging and a transport document.
