Chemical imports require careful HS classification (Chapter 28–38), safety documentation, and environmental clearances. Many chemicals have dual-use concerns (industrial and potential for misuse), and India's import regulations treat them with extra scrutiny — particularly for precursor chemicals.
Regulatory Requirements for Chemical Imports
| Category | Regulator | Requirement |
|---|---|---|
| Hazardous chemicals | MoEFCC / CPCB | NOC from Central Pollution Control Board for listed hazardous substances |
| Pesticides / agrochemicals | CIB&RC | Registration under Insecticides Act; import permit from CIB&RC |
| Narcotic precursors | NCB / CBIC | Strict controls; import only via designated agencies |
| Ozone-depleting substances | MoEFCC | ODS import license; phase-down schedules under Montreal Protocol |
| Industrial chemicals (general) | CBIC | Standard BoE; SDS required for hazardous classification |
Safety Data Sheet (SDS) on the Bill of Entry
For hazardous chemicals classified under GHS (Globally Harmonized System), a Safety Data Sheet must be submitted with the customs documents. The SDS confirms:
- Chemical composition and CAS number
- Hazard classification (flammable, corrosive, toxic, etc.)
- Emergency procedures
- Storage and handling requirements
- IATA/IMDG dangerous goods classification for transport

Frequently asked questions
Standard BoE documents plus: Safety Data Sheet (SDS), CPCB NOC for hazardous chemicals, CIB&RC import permit for pesticides, ODS license for ozone-depleting substances.
Most chemicals: BCD 0–10% (Chapters 28–38). IGST 18%. Fertilizers may have lower rates. Check specific HS code — duty varies significantly within the same chapter.
