NIS2 for chemical companies in Belgium

Chemicals is listed in Annex II of the NIS2 directive. Medium and large companies are important entities (lighter supervision, after the fact). In Belgium, the rules come from the NIS2 Law of 26 April 2024, applicable since 18 October 2024; the authority is the Centre for Cybersecurity Belgium (CCB), plus a sector authority for some sectors.

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 Belgium requires

• The law of 26 April 2024 has applied since 18 October 2024.
• Registration on Safeonweb@Work was due by 18 March 2025 (18 December 2024 for some digital providers). Not registered yet? Do it now.
• Essential entities had to complete a first conformity assessment by 18 April 2026 and must hold CyberFundamentals (CyFun®) or ISO/IEC 27001 certification by 18 April 2027.
• The CCB framework has three assurance levels — Basic, Important, Essential. Basic is recommended for suppliers of NIS2 entities that are not in scope themselves.
• Important entities are supervised after the fact (for example after an incident); a voluntary CyFun® or ISO 27001 assessment gives them a presumption of conformity.

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 Belgium?

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.
