Rules in IndiaOK
- Not on the Indian banned-pesticide, drug-precursor, narcotic, psychotropic or new-drug lists we check.
- Normal factory, storage and GST rules still apply.
Exporting from IndiaOK
- Not on the SCOMET export-control list or the precursor export list.
- Not approved as a pesticide in the EU: food sent there must carry almost none of it.
- The buyer’s country may still have its own import rules.
Global treaties & export marketsOK
- Not listed by the Stockholm Convention (persistent pollutants), the Rotterdam Convention (prior consent before export) or the Montreal Protocol (ozone layer).
- Registered under EU REACH, so EU importers can buy it under an existing registration.
- Active on the US TSCA Inventory, so it can be imported into the US without a new-chemical notice.
- Listed on the Australian Inventory of Industrial Chemicals (AICIS), so it can be introduced into Australia as an existing industrial chemical.
- EU: harmonised classification (CLP Annex VI, index 607-063-00-9): Acute Tox. 4. Suppliers in the EU must label it this way.
Import dutyOK
- About ₹27,730 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: 2915, saturated acyclic monocarboxylic acids and their derivatives (carboxylic acid group).
- 46 of 48 lines under heading 2915 pay basic customs duty 7.5%; with social welfare surcharge and IGST 18% that makes about 27.73%.
- Confirm the exact 8-digit code with your customs broker before you import.

- Harmful in contact with skin
- Causes severe skin burns and eye damage
- Always read the supplier’s safety data sheet (SDS) before handling.
Storage, transport & PESOOK
- Flash point about 56 °C (Hazardous Substances Data Bank (HSDB)).
- It is not a hydrocarbon, so the Petroleum Rules do not class it; storage still follows the state fire service’s rules and the factory licence.
- Ships as UN 2529 (Flammable Liquid Corrosive): dangerous-goods rules apply by road, sea (IMDG) and air (IATA), with labels, packaging and a transport document.
Food residue limitsCHECK
- India (FSSAI) has no specific limit, so the default 0.01 mg/kg applies to food.
- EU: not approved; most EU food limits are at the detection limit.
