HCS 2024 adds practical labeling allowances for very small containers - including pull-out, fold-back, and tag-style labels - so manufacturers can communicate the full GHS hazard information even when a standard label cannot physically fit on the container. These provisions live in the shipped-label rules under 29 CFR 1910.1200(f) and apply to manufacturers and importers. They do not change the duty to communicate hazards; they change the format when a container is too small for a conventional label.
At a glance: HCS 2024 lets shipped small containers use pull-out / fold-back / tag labels, and the smallest inner containers show reduced core elements while the outer package carries the full label. The format flexes; the hazard duty doesn't — no volume-based "no label" rule. Workplace/secondary bottles still follow (f)(6), not this. HCS 2024 adds pull-out, fold-back, and tag-label options so manufacturers can communicate full GHS hazard information on containers too small for a conventional label, but it does not exempt any container from labeling and does not change workplace secondary-container rules under 1910.1200(f)(6).
The Problem HCS 2024 Solves
A full GHS shipped label requires the product identifier, signal word, hazard statements, precautionary statements, pictograms, and supplier identification. On a 5-mL vial or a tiny reagent ampoule, all of that simply will not fit. Before HCS 2024, manufacturers struggled with how to comply on miniature packaging. HCS 2024 codifies a tiered, practical approach.
What's Now Allowed for Small Packages
The allowances scale with how small the container is:
| Container situation | Allowed approach |
|---|---|
| Full label fits | Standard GHS label with all six elements |
| Label too small for all text | Pull-out, fold-back, or tag label carrying the full required information |
| Smallest immediate containers | Reduced set of core elements on the inner container, with full information on the outer package |
In every case, the outer package must carry the complete, conforming GHS label, and the immediate container must still bear - at minimum - the product identifier and core hazard signals so a worker is never left guessing.
Format flexes with container size (shipped containers, 1910.1200(f)(12))
No blanket "no label under 100 mL" rule. The outer package always carries the complete label. Workplace bottles follow (f)(6), not this.
Important: HCS 2024 does not create a blanket "no label needed below 100 mL" rule. Paragraph (f)(12) is real and its thresholds are real, but it binds the manufacturer's shipped container only — it gives you nothing for the bottles you fill in-house, which stay under (f)(6) at any size. The relief is format flexibility on shipped containers, not an exemption from hazard communication.
The exact thresholds: ≤100 mL and ≤3 mL (29 CFR 1910.1200(f)(12))
The accommodations live in paragraph (f)(12) of the standard itself, headed "Small container labelling" — not in Appendix C. That distinction matters when you are quoting a citation to an inspector or a supplier: Appendix C runs C.1 through C.4 and contains no C.9. They turn on two size thresholds, both for shipped containers only:
| Immediate container | What it may show | Hard condition | Where the full label lives |
|---|---|---|---|
| ≤ 100 mL (29 CFR 1910.1200(f)(12)(ii)) | Product identifier, pictogram(s), signal word, and the chemical manufacturer's name & phone number, plus a statement that the full label information is provided on the immediate outer package | Only where a pull-out, fold-back, or tag label carrying full info is not feasible ((f)(12)(i)) | Full (f)(1) label on the immediate outer package ((f)(12)(iv)(A)) |
| ≤ 3 mL (29 CFR 1910.1200(f)(12)(iii)) | No label required — but the container must bear, at a minimum, the product identifier | Only where any label would interfere with the normal use of the container | Full (f)(1) label on the immediate outer package ((f)(12)(iv)(A)) |
Note the order of operations: the reduced element sets are a last resort. Paragraph 1910.1200(f)(12)(i) is a gate, not a menu — it says the accommodations apply "where the chemical manufacturer, importer, or distributor can demonstrate that it is not feasible to use pull-out labels, fold-back labels, or tags containing the full label information." A manufacturer must first attempt a pull-out, fold-back, or tag label carrying the full required information; only when that is genuinely infeasible do the (f)(12)(ii) / (f)(12)(iii) reduced sets come into play — and even then a compliant, complete label always travels on the outer package.
The outer-package duty has two prongs, and almost nobody quotes the second
Paragraph 29 CFR 1910.1200(f)(12)(iv) is where the accommodation is paid for, and it requires two things on the immediate outer package:
- (A) the full (f)(1) label information for each hazardous chemical inside — and that label "must not be removed or defaced, as required by paragraph (f)(9)."
- (B) a statement that the small container(s) inside must be stored in the immediate outer package bearing the complete label when not in use.
Prong (B) is the one that reaches past the loading dock and into your storeroom. The regulation anticipated exactly what happens next — the carton gets flattened and binned, and a vial with a four-element label is left sitting on a shelf with no hazard statements anywhere near it. So it required the box to say, in print, that the vial goes back in the box. If you are the employer receiving these containers, treat that statement as an instruction addressed to you: keep the outer package. It is not packaging waste; it is the part of the label system that carries the full hazard information.
Shipped vs. Workplace Labels - Don't Mix Them Up
The small-package provisions sit inside the manufacturer/importer shipped-label regime. Workplace labeling is a separate world:
| Label type | CFR cite | Rule |
|---|---|---|
| Shipped (manufacturer) | 1910.1200(f)(1) | Full GHS label on the container as shipped; small-package allowances apply here |
| Workplace / secondary | 1910.1200(f)(6) | Two options: (1) full GHS label, or (2) product identifier + words/pictures/symbols giving general hazard information |
| Immediate use | 1910.1200(f)(8) | No label needed if the chemical is transferred for immediate use by the employee who made the transfer, within that shift |
So if your concern is a spray bottle or a small jar you fill on-site, you are in (f)(6) territory, not the small-package shipped rules. The two (f)(6) options give you flexibility for in-plant containers without invoking the new packaging provisions at all.
What Still Applies to Every Small Container
- Eight pictograms remain the OSHA set; the GHS09 environmental pictogram is voluntary and never counts as a ninth required symbol.
- The product identifier must match the SDS, even on a pull-out label.
- The outer package must always carry a complete, conforming label.
- The duty to train employees on reading these labels applies (see the HCS 2024 training obligation).
Compliance Timeline
| Party | Scope | Deadline |
|---|---|---|
| Manufacturers / importers | Substances | May 19, 2026 |
| Employers | Substances (workplace labels) | November 20, 2026 |
| Manufacturers / importers | Mixtures | November 19, 2027 |
| Employers | Mixtures (workplace labels) | May 19, 2028 |
Small-Package Label Checklist
- Outer package carries the full conforming GHS label
- Inner/immediate container shows at least the product identifier and core hazard signals
- Pull-out/fold-back label, if used, carries all required elements and stays attached
- Product identifier matches the SDS
- Workplace-filled containers handled under (f)(6) options, not the shipped rules
- Employees trained to find and read the information on small-format labels
Right label, right container size, every time
Small-format labeling is where the hazard duty and the physical container collide. HazComFast generates GHS-consistent labels, matches them to the right Avery or thermal template for the container, and keeps workplace (f)(6) labeling straight from the shipped rules. Make the labels free, then run labeling across your sites on trial.

Frequently Asked Questions
What did HCS 2024 change about small-package labeling?
HCS 2024 added practical allowances for very small containers where a full GHS label will not physically fit. These include using pull-out, fold-back, or tag-style labels, and in the smallest cases displaying a reduced set of elements on the immediate container while the full information travels on the outer package (29 CFR 1910.1200(f)(12)).
Does a small container still need a label?
Yes. Every container of a hazardous chemical shipped from a manufacturer still requires hazard communication under 1910.1200(f)(1). HCS 2024 changes the format options for tiny containers, not the underlying duty to communicate the hazard.
Do small-package allowances apply to workplace secondary containers?
No. The small-package provisions are part of the manufacturer/importer shipped-label rules. Workplace and secondary containers are governed separately by 1910.1200(f)(6), which offers two labeling options, plus the immediate-use exception in (f)(8).
When must manufacturers comply with the new label rules?
For substances, manufacturers and importers must comply by May 19, 2026. For mixtures, the manufacturer compliance date is November 19, 2027. Employers update, as necessary, any affected alternative workplace labeling by November 20, 2026 (substances) and May 19, 2028 (mixtures), under 29 CFR 1910.1200(j) as extended by OSHA's January 15, 2026 rule.
Is there a blanket 'no label needed under 100 mL' rule?
No. HCS 2024 gives no volume-based EXEMPTION from labeling. But the 100 mL and 3 mL thresholds are real and they are in 29 CFR 1910.1200: paragraph (f)(12), 'Small container labelling' (added by HCS 2024), lets a SHIPPED container of 100 mL or less carry a reduced label, and one of 3 mL or less carry the product identifier alone — only where a pull-out/fold-back/tag label is not feasible, and only with the full label on the outer package. It is format relief on the manufacturer's container, not permission to leave anything blank, and it never applies to workplace/secondary containers.
