EU Correction on 2-chloroethanol: What Pesticide Manufacturers and Laboratories Must Review

Key data

Pesticide manufacturers and residue analysis laboratories working with 2-chloroethanol have a concrete task ahead: verify that their compliance procedures cite and apply the corrected version of Regulation (EU) 2026/164, not the original. The Implementing Regulation (EU) 2026/2070, published on 18 September 2026, introduces corrections of material errors in that regulation without altering the substantive regulatory framework already established.

The reference to 2-chloroethanol is not minor: it is a relevant metabolite in the assessment of pesticide residues, which places it at the centre of residue controls in food and in the procedures for authorising plant protection products. Any error in the reference regulation can generate uncertainty in inspections, audits or in the application of maximum residue limits (MRL).

What does this regulation establish?

Implementing Regulation (EU) 2026/2070 is a formal correction of Regulation (EU) 2026/164. Its function is to amend material errors detected in the original text, without modifying the regulatory substance or the maximum residue limits already established.

The corrected aspects are of a technical and specific nature. The regulation does not publicly detail each specific error beyond qualifying them as "material errors", but its scope is limited to the regulatory treatment of 2-chloroethanol, a metabolite that appears in the toxicological assessment of certain pesticides and that may be present as a residue in agri-food products.

The competent authorities of the Member States are also within the scope of application: they must update their internal references to apply the corrected version in official inspections and controls.

Economic and operational impact

The direct economic impact of this correction is limited: it does not introduce new obligations, does not modify amounts, does not establish new maximum residue limits and does not generate additional regulatory costs in itself.

However, the operational impact is real for those working with 2-chloroethanol in their procedures:

• Residue analysis laboratories: must update the regulatory references in their internal procedures, reports and accreditations. Using the erroneous version in an official control report can generate discrepancies with the competent authority.
• Pesticide manufacturers: authorisation files, technical data sheets and compliance documentation citing Regulation 2026/164 must verify that they reference the corrected version.
• Agri-food operators: in certification audits (IFS, BRC, GlobalG.A.P.) or in export controls, the reference to the correct regulation may be relevant to demonstrate compliance.

The main cost is not economic but rather document management and procedure updating: reviewing, updating and communicating internally the change in regulatory reference.

Who does it affect?

• Manufacturers and distributors of pesticides and plant protection products working with active substances whose metabolism generates 2-chloroethanol.
• Agri-food sector companies subject to pesticide residue controls in their products (fruits, vegetables, cereals, etc.).
• Residue analysis laboratories accredited for official control of pesticides in food and feed.
• Competent authorities of the Member States responsible for official controls of pesticide residues.
• Regulatory advisors and compliance consultants in the plant protection and agri-food sector.

Practical example

An accredited laboratory that performs pesticide residue analysis for a fruit exporting company has in its internal analysis procedure the reference to Regulation (EU) 2026/164 as the regulatory basis for the assessment of 2-chloroethanol.

If that laboratory issues an official control report citing the original version (with material errors) instead of the version corrected by Regulation 2026/2070, it may find that the competent authority of the destination country or the accreditation body questions the validity of the regulatory reference used. Updating the internal procedure is, therefore, a preventive action of low cost but high relevance for the integrity of the reports issued.

Similarly, a pesticide manufacturer that has an authorisation file in process or under review where 2-chloroethanol appears as a relevant metabolite must ensure that the documentation presented to the competent authority cites Regulation 2026/2070 as the current reference.

What should companies do now?

1. Identify all internal documents that cite Regulation (EU) 2026/164 as a regulatory reference: laboratory procedures, authorisation files, compliance sheets, internal audit reports.
2. Update the references so that they point to the version corrected by Implementing Regulation (EU) 2026/2070, published on 18 September 2026.
3. Communicate the change internally to the quality, regulatory and laboratory teams working with 2-chloroethanol as a metabolite in their assessments.
4. Verify with the competent authorities of the corresponding Member State whether they have already updated their references for official controls, especially if inspections or audits are scheduled.
5. Review files in process before regulatory authorities where 2-chloroethanol appears as a relevant metabolite, to ensure that the documentation presented is consistent with the current regulatory version.
