New EPA rules for new chemicals, an EU microplastics duty, and a CLP date we corrected

Nothing in October changed what a safety data sheet must say for common chemicals. Two batches of EPA significant new use rules for newly notified substances carry hazard communication terms. One took effect on 2026-10-26, the other applies from 2026-12-14. In the EU, an instruction duty for diagnostic devices containing microplastics started on 2026-10-17. The trichloroethylene, atrazine, trifluoroacetic acid and transport items are proposals, not law. We also correct a date: revised CLP label formatting applies from 2028-01-01, not 2026-07-01.

What was published

8 items. Each names its instrument, its dates and its primary source.

What did not change

Checked in this window and confirmed unchanged. This is usually the half of the issue that saves you an afternoon.

• No new Adaptation to Technical Progress to CLP EC 1272/2008 was found in the Official Journal in this window. We checked the L-series titles for every publication day from 2026-09-30 to 2026-10-28.
• Correction: Regulation (EU) 2025/2439 moved the revised CLP label formatting, advertising and distance-sales rules to 2028-01-01. Our September issue and EU CLP guide said 2026-07-01, and we are correcting both.
• The other CLP revision tranches stand: 2026-07-01 for most classification and labelling changes, and 2027-01-01 for poison-centre and notification changes.
• Under Delegated Regulation (EU) 2023/707, substances already on the market before 2025-05-01 had until 2026-11-01 to carry the new endocrine, PBT and PMT hazard classes.
• REACH EC 1907/2006 Annex II, which sets the safety data sheet format itself, is unchanged. So are Annex XVII restrictions and Annex XIV authorisation-list entries.
• No ECHA SVHC Candidate List addition was found from 2026-09-30 to 2026-10-14; the last update we confirmed is 2026-02-04. ECHA's list page could not be read for the second half, so we make no claim for it.
• OSHA: no Federal Register document touching 29 CFR 1910.1200 in the window. The next HazCom date is 2026-11-20, when employers must have updated workplace labels, written programmes and training for substances.
• PHMSA: no final hazardous materials rule in the window, so Section 14 transport data stands.
• No GB mandatory classification list change. The most recent change to the GB MCL List took effect on 2026-05-21.
• No occupational exposure limit change from NIOSH or OSHA in the window, so Section 8 limits stand.
• The 24th Adaptation to Technical Progress remains at draft and WTO-notification stage, with no regulation number and no Official Journal date. We do not cite it.
