CWC Registration & Declarations (NACWC) in brief
Who it applies to, what it costs, how long it takes and which law governs it — before the details.
Under Section 18 of the Chemical Weapons Convention Act, 2000, anyone engaged in the production, processing, acquisition, consumption, transfer, import, export or use of a toxic chemical or precursor listed in Schedules 1 to 3 of the Convention’s Annex on Chemicals, or in the production of Discrete Organic Chemicals (including those containing phosphorus, sulphur or fluorine — PSF), must register with the registration authority before commencing business, subject to prescribed exemptions and thresholds. Registered persons must then furnish declarations and returns. India’s National Authority Chemical Weapons Convention (NACWC), an office of the Cabinet Secretariat, runs the online e-filing system; its guidance asks declaring units to file annual declarations on or by 31 January.

What Is CWC Registration & Declarations (NACWC)?
A quick, plain-language explanation before the details.
India has signed the Chemical Weapons Convention, which bans chemical weapons and tracks chemicals that could be misused to make them. Businesses that make, use or trade those chemicals register with India’s National Authority and report their activities every year, so India can report to the international body that verifies the Convention.
The Chemical Weapons Convention Act, 2000 gives effect to the Convention in India. Section 18 requires registration, subject to prescribed exemptions and thresholds, of persons engaged in activities involving toxic chemicals or precursors in Schedules 1 to 3, or in producing Discrete Organic Chemicals; Section 18(6) requires registered persons to furnish prescribed information, declarations and returns; and Section 12 empowers the National Authority to call for information. Section 15 restricts Schedule 1 activities, Section 16 restricts Schedule 2 transfers, and Section 17 requires imports and exports to follow the Export and Import Policy.
Administered by the National Authority Chemical Weapons Convention (NACWC), set up as an office of the Cabinet Secretariat, Government of India, which is India’s focal point with the Organisation for the Prohibition of Chemical Weapons (OPCW). Declarations are filed on NACWC’s online e-filing system.
Under Section 18(5), a certificate of registration is valid for the period specified in it and is renewable on payment of the prescribed fee. Declarations are recurring — past activities every year and anticipated activities before the year begins.

Talk to an Expert →Why Does CWC Registration Matter for Chemical Businesses?
For chemical companies, the CWC Act is a criminal-law compliance, not a formality. Here is why registration and declarations matter.
Talk to a Chemical Compliance Expert →Required by Law
Section 18 of the CWC Act requires registration before commencing business with scheduled chemicals or DOC production, subject to prescribed thresholds.
Serious Penalties
Failure to register is punishable under Section 39, and failure to furnish declarations or returns under Section 46 of the Act.
Export & Import Access
Scheduled-chemical trade follows the Export and Import Policy — Schedule 2 exports need DGFT permission and Schedule 1 imports need prior permission.
Inspection Readiness
Plant sites above verification thresholds may be selected for OPCW inspection; accurate declarations make inspections smoother.
Buyer & Partner Trust
Global buyers of speciality chemicals expect suppliers to be CWC-compliant and transparent about scheduled chemicals.
National Obligation
India’s declarations to the OPCW are built from company declarations — late or wrong data affects the national return.

What You’ll Receive
What Documents Are Required for CWC Registration & Declarations?
CWC compliance is data-driven — accurate chemical identities and quantities matter most. Keep clear scans and production data ready — everything is collected securely over WhatsApp or email.
Entity & Site
Who and where- Certificate of Incorporation / constitution documents
- PAN, GST and IEC of the entity
- Plant site address and layout of individual plants
- Factory licence and pollution-control consents for the site
Chemicals & Production
What you make and use- Product and raw-material list with IUPAC names and CAS numbers
- Production, processing and consumption quantities by calendar year
- Production capacity of plants handling scheduled chemicals
- Process description where needed to classify activities
Trade Records
Imports and exports- Country-wise import and export quantities of scheduled chemicals
- Shipping bills / bills of entry for scheduled chemicals
- DGFT permissions or authorisations held
- End-use / end-user certificates where required
CAS numbers are key
Schedule families and DOC / PSF status are identified by chemical identity and CAS number. Trade names alone are not enough to decide whether a chemical is declarable.
Thresholds differ by schedule
Per NACWC, Schedule 2 plant sites declare above 1 kg (2A*), 100 kg (2A) or 1 tonne (2B); Schedule 3 above 30 tonnes; DOC plant sites above 200 tonnes, or 30 tonnes of a PSF chemical in a plant.
Calendar-year data
Declarations use calendar-year quantities, not the financial year. Opening and closing figures must reconcile across forms.
Traders declare too
Importers and exporters of Schedule 2 and Schedule 3 chemicals who do not produce them still declare their transfers through the trader forms.
