Two EU dates already passed, and four US rules worth reading
The headline for anyone selling a hazardous mixture in the EU is that two dates have already passed. New hazard classes reached mixtures on 2026-05-01, and new label formatting and online-sales rules on 2026-07-01. No new Adaptation to Technical Progress and no SVHC Candidate List addition were published in this window. In the United States the movement was in transport and in California, not in OSHA 29 CFR 1910.1200, which saw no rule or guidance at all.

Commission Delegated Regulation (EU) 2023/707 — four new hazard classes in CLP Annex I
- Published
- 2023-03-31
- Applies from
- 2026-05-01
- Status
- in force
- Effect on documents
- Changes the sheet and the label
A mixture placed on the EU market from 2026-05-01 must be classified and labelled for the four hazard classes added to CLP EC 1272/2008: endocrine disruption for human health, endocrine disruption for the environment, PBT/vPvB and PMT/vPvM. A mixture already on the market before that date is exempt until 2028-05-01. Substances have been in scope since 2025-05-01, with their own transitional end on 2026-11-01.
What we did: We rewrote our EU CLP guide. It stated a September 2026 mixture deadline, which does not exist anywhere in CLP EC 1272/2008, and it now carries 2026-05-01 and the 2028-05-01 transitional end instead. Our EU draft does not automatically determine PBT/vPvB or endocrine-disrupting status, and Section 2.3 of the draft says so in those words rather than guessing.

Regulation (EU) 2025/2439 — application dates for the CLP revision, Regulation (EU) 2024/2865
- Published
- 2025-12-03
- Applies from
- 2026-07-01
- Status
- in force
- Effect on documents
- Changes the label
The CLP revision applies in tranches, and Regulation (EU) 2025/2439 rescheduled them. From 2026-07-01 the new label formatting and legibility rules apply, as do new information requirements for advertisements and for distance and online sales of hazardous mixtures. Later tranches follow on 2027-01-01 and 2028-01-01. This is a labelling-format and disclosure change, not a reclassification.
What we did: Read the dates out of 2025/2439, never out of 2024/2865 alone — that is where the confusion in the market comes from. No change to the draft safety data sheet: the advertising duty falls on the seller, not on the document. We have opened a check of our GHS Label output against the new formatting and legibility rules.

Hazardous Materials: Reducing Costs to Domestic Shippers and Carriers of Limited Quantities
- Published
- 2026-08-04
- Applies from
- 2026-09-03
- Status
- in force
- Effect on documents
- Changes the safety data sheet
A reduced-size limited-quantity marking is now allowed for hazardous materials moving by highway, rail or vessel. It is an option for the shipper, not a new obligation, and it sits alongside the existing marking.
What we did: No change to our output. Section 14 of the draft carries the UN number, proper shipping name, hazard class and packing group. Marking dimensions are decided at packing time, not in a data sheet.

Hazardous Materials: Reducing Burdens on Domestic Companies Using Battery-Powered Equipment in Trades
- Published
- 2026-08-04
- Applies from
- 2026-09-03
- Status
- in force
- Effect on documents
- Changes the safety data sheet
The maximum quantity of lithium batteries that may travel under the Materials of Trade exception went up. Tradespeople carrying battery-powered equipment are the intended beneficiaries.
What we did: No change to our output, and worth knowing if you ship lithium cells: the exception you qualify for is a Section 14 statement, and the one you relied on last quarter may now be wider.

Welding fumes added to the Proposition 65 list for cancer
- Published
- 2026-07-17
- Applies from
- 2027-07-17
- Status
- in force
- Effect on documents
- Changes the label
Welding fumes are now on the California Proposition 65 list as a carcinogen. The clear and reasonable warning duty normally follows 12 months after listing, which puts it at 2027-07-17 for exposures and products in California.
What we did: Our Proposition 65 line in Section 15 is keyed to a CAS number. Welding fumes have no single CAS, so we did not invent one to automate this. If you supply welding consumables into California, this is a label and workplace matter for you, ahead of any data sheet.

Significant New Use Rule on a Certain Chemical Substance; Multi-Walled Carbon Nanotubes
- Published
- 2026-07-24
- Applies from
- 2026-09-22
- Status
- adopted
- Effect on documents
- Changes the safety data sheet
A final Significant New Use Rule under TSCA requires 90-day notice to the Environmental Protection Agency before manufacturing or processing the named multi-walled carbon nanotube substance for the newly designated use.
What we did: A final Significant New Use Rule is a Section 15 fact for the substance it names. It does not change any GHS classification or pictogram. If you handle this substance, the regulatory-information section of your draft should name the rule.

Perchloroethylene and carbon tetrachloride; TSCA regulation; compliance date extensions
- Published
- 2026-07-28
- Applies from
- 2026-07-28
- Status
- in force
- Effect on documents
- No change to the document
Workplace Chemical Protection Program deadlines under the existing TSCA rules for these two solvents moved later. Initial inhalation monitoring goes to 2027-06-21, and the exposure-limit, regulated-area, training and respiratory-programme deadlines to 2027-09-20.
What we did: Nothing changes in the document. These are dates for putting controls in place, which is why they matter to a plant manager and not to Section 8 text.

Commission Delegated Regulation (EU) 2026/1278 — amending the PIC Regulation (EU) 649/2012
- Published
- 2026-08-12
- Applies from
- 2026-10-01
- Status
- adopted
- Effect on documents
- No change to the document
Export and import notification listings under the prior informed consent regime were amended, covering carbendazim, metribuzin, several withdrawn pesticide active substances, chromium and arsenic compounds and Dechlorane Plus.
What we did: No effect on classification, on the label or on any of the 16 sections. Listed here because it is the only chemicals instrument actually published in the Official Journal during this window, and its absence would look like an oversight.

Proposed revision of the GB mandatory classification and labelling list
- Published
- 2026-07-27
- Adoption date
- not fixed
- Status
- proposed — not law
- Effect on documents
- No change to the document
A revision of GB mandatory classification entries is under World Trade Organization notification. It is a proposal at consultation stage, not law, and no adoption date is fixed.
What we did: Nothing to implement. We log GB divergence as it is adopted, never as it is proposed, because a proposal that changes in consultation would put a wrong classification into a draft.
Read the primary sourceWhat did not change
Checked in this window and confirmed unchanged. This is usually the half of the issue that saves you an afternoon.
- OSHA 29 CFR 1910.1200: no final rule, no compliance-date change and no interpretation letter was published in this window.
- No new Adaptation to Technical Progress to CLP EC 1272/2008 was published in the Official Journal. The most recent, the 23rd, applies from 2027-02-01.
- REACH EC 1907/2006 Annex II, which sets the safety data sheet format itself, is unchanged since Regulation (EU) 2020/878.
- No REACH Annex XIV authorisation-list addition and no Annex XVII restriction amendment was published in this window.
- No ECHA SVHC Candidate List addition in this window. The last confirmed addition was announced on 2026-02-04, and the update expected around mid-2026 has not appeared.
- No dated change to the NIOSH pocket guide or the OSHA annotated permissible exposure limit tables, so Section 8 exposure limits stand.
- The Environmental Protection Agency published draft risk evaluations for ethylene dibromide, 1,2-dichloropropane, 1,1,2-trichloroethane, trans-1,2-dichloroethylene and the dichlorobenzenes. These are science documents open for comment, not rules.
- The UN Sub-Committee of Experts on the GHS met from 2026-07-08 to 2026-07-10. Its outcomes feed a future revision of the GHS, not the one in force.
How to read this issue
An item marked as changing the sheet or the label is one where an adopted instrument with a date of application alters what the document must say. An item marked proposed is not law and changes nothing yet. Nothing here is legal advice, and a draft we generate is for professional review before it is issued.
A draft safety data sheet or GHS label is $5 per document, sourced value by value, delivered as editable .docx and PDF.
