NIS2 for chemical companies in the Netherlands

Chemicals is listed in Annex II of the NIS2 directive. Medium and large companies are important entities (lighter supervision, after the fact). In Netherlands, the rules come from the Cyberbeveiligingswet (Cbw — Cybersecurity Act), applicable since 15 August 2026; the authority is the National Cyber Security Centre (NCSC) runs the register; supervision by the Rijksinspectie Digitale Infrastructuur (RDI) and the sector supervisors.

Who is covered in this sector

• Manufacturers of substances and mixtures
• Distributors of substances and mixtures (within the meaning of REACH)

Companies that only use chemicals in their own processes are not in scope because of that.

The threats we see most in chemicals

• Attacks on process-control systems (safety impact)
• Ransomware on production and logistics
• Theft of formulations and trade secrets
• Supplier and contractor access abuse

Five priority measures

1. 01 Separate safety-instrumented systems and OT from IT
2. 02 Contractor access management with logging
3. 03 Incident scenarios combining cyber and process safety
4. 04 Offline backups of recipes and control configurations
5. 05 Security review of distributors and logistics partners

What Netherlands requires

• The Act entered into force on 15 August 2026, together with the Critical Entities Resilience Act (Wwke).
• Registration in the national register (Mijn.NCSC.nl) is mandatory since 15 August 2026: name, address, sector, EU countries served, contact details and, where relevant, IP ranges.
• Cloud, data-centre, DNS and managed-service providers register where their head office is; other entities register in every EU country where they operate.
• The duty of care (risk management) and the duty to report significant incidents apply from the same date.
• Non-compliance can lead to fines and to orders subject to a penalty payment (last onder dwangsom).

Significant incidents: early warning within 24 hours, notification within 72 hours, final report within one month. Fines set by the directive: up to €10 million or 2% of worldwide turnover for essential entities, and up to €7 million or 1.4% for important entities (whichever is higher).

Frequently asked questions

Is my chemical companie company in scope of NIS2 in Netherlands?

Chemicals is an Annex II sector. Medium and large companies are important entities (lighter supervision, after the fact). Small companies are generally out of scope unless designated. Our NIS2 check gives you the answer in two minutes.

What should we do first?

Register if you are in scope, name an owner, run a short risk assessment, and fix the basics: MFA, tested backups, patching, incident routine.

We are a supplier to this sector. Does it affect us?

Yes, indirectly: your customers must secure their supply chain and will ask you for evidence. See our supplier questionnaire guide.
