Prominently displayed is a requirement, and a small bottle makes it a design problem.

What has to be there

Six elements, with the signal word, hazard statements and pictograms located together, in accordance with Appendix C, prominently displayed, in English. On a 100 mL cylinder round that is a genuine constraint.

The grouping is what breaks the layout

Designers naturally distribute the elements for balance, and the paragraph requires three of them adjacent. Discovering that after artwork approval means rebuilding the label rather than adjusting it.

Hazard statements multiply

A product with several hazard classes and categories carries a statement for each, and they are prescribed wordings rather than summaries. The count is a consequence of the classification and not something to negotiate.

Which argues for a larger container or a different format

A wrap-around label, an extended-content label, or simply a bigger bottle. All three are decisions that have to be made before the case quantity is committed.

And the label has to survive the chemistry

These are solvents, acids and bases, and they get on the outside of the bottle. A label that has become illegible has removed exactly the information the regulation required it to carry.

Which is a compliance failure, not a cosmetic one

The same point the brake fluid property makes under a different statute. An unreadable required label is an absent required label.

The small bottle is the common case here

A reagent or a sample size is exactly where this bites, because the label content is driven by the hazard rather than by the container, so a 100 ml bottle of something with four hazard classes carries the same text a gallon jug would. Extended-content labels exist for precisely this and they are worth pricing early.

Test it with the product on it

Wipe the chemical down the side of a labeled bottle, handle it for a week, and look at the edges and the ink. It costs one bottle and it answers the question before a print run does.

Written from federal regulation and from measured catalog data, not from a plant floor. Hazard classification is a technical exercise with appendices behind it, and nothing here classifies a chemical or writes a label. The point of these pages is to show which regime applies and what it asks for.
