What does H361 mean?

Categories and label elements

CLP abbreviation	Pictogram	Signal word
Repr. 2	GHS08Health hazard	Warning

Related precautionary statements (P codes)

The precautionary statements that CLP Annex IV assigns to this class. Not all of them go on the label: under CLP Article 28(3), no more than six precautionary statements appear on the label unless the nature and severity of the hazard require more; the selection depends on the product and its users.

When does a mixture need H361?

Whether a mixture needs H361 is calculated from the classes and concentrations of its components. The values in the rule file for this code are:

• Threshold method: a Repr. 2 component at ≥ 3 % gives the mixture the same class. (CLP Annex I Table 3.7.2)
• If a component has a harmonised specific concentration limit (SCL) and meets it, the mixture takes the corresponding class directly.

For a step-by-step worked example see classifying a mixture under CLP.

Where is H361 written in the SDS?

H361 is tracked in three places of the SDS: the classification line in Section 2.1 ("Repr. 2"), the label elements in Section 2.2 and the component list in Section 3. Section 16 repeats the explanation of the code. In addition, it appears in Section 11 (toxicological information), under heading 11.1, as a "Classified" line when the class is among the classes of the mixture.

How does H361 appear on the label?

The label elements for H361 are: pictogram GHS08 (health hazard); it is written with the signal word "Warning". In the Chemoris template Section 2.2 carries at most 8 H statements; if the limit is exceeded the least severe ones are dropped and a warning is shown. For the bottom of the label, 6 P statements are candidates for this class in CLP Annex IV; under CLP Article 28 at most 6 of them are selected.

Where does it appear in the safety data sheet?

• Section 2.1: classification; the class abbreviation and H361 are given together.
• Section 2.2: label elements; H361 with its full text, pictogram and signal word.
• Section 3: composition table; in the row of every component that has this class.
• Section 16: the full text of the H statements cited as codes in earlier sections.

Class criteria and thresholds for H361

The values below come from the Chemoris rule file (CLP Annex I). They show the condition under which H361 arises in a mixture. For physical hazards and other classes that depend on test data, the result comes from the mixture's own measurement, not from component percentages.

H361 compared with H361d and H361f

The table below puts H361 next to its closest neighbouring statements; the values are read from the rule data.

H361 and H361d carry the same signal word (Warning). Both are shown with the same pictogram (GHS08). H361 and H361f carry the same signal word (Warning). Both are shown with the same pictogram (GHS08).

H361d H361f

In which SDS sections does H361 appear?

H361 does not stay only in the label section of an SDS; the class itself and the precautionary statements assigned to it shape the content of other sections too. The counts are calculated from the P statements that Annex IV assigns to this class.

Statements that appear on the label together with H361

H361 is never printed alone on a label; it sits next to the pictogram and the signal word. The Chemoris selection method (response, prevention, storage, disposal in that order; core statements first) gives these first 5 candidates for this class:

The GHS08 pictogram and “Warning” are printed together. This ranking applies because a label usually carries at most 6 statements; when a combined statement is selected, its parts are not printed again.

Official EU wording of H361 in other languages

When a product is exported to the EU, the SDS and label are expected in the official language of the Member State where it is placed on the market (REACH Article 31(5)). The table gives the official wording of H361 from the CLP Annex III/IV language versions published in the Official Journal of the European Union. Source: EUR-Lex CELEX 02008R1272-20260701.

Common mistakes with H361

• Mixing up signal words: if any class requires “Danger”, only “Danger” is printed and “Warning” drops out (CLP Article 20(3)).
• Writing unlimited H statements for a multi-class product: in the Chemoris template, Section 2.2 holds at most 8 H statements.

Related hazard statements

Other H statements in the same hazard family as H361 (Repr.). The difference between categories mostly comes from the degree of severity.

• H360May damage fertility or the unborn child <state specific effect if known > <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard> .
• H360DMay damage the unborn child.
• H360DfMay damage the unborn child. Suspected of damaging fertility.
• H360FMay damage fertility.
• H360FDMay damage fertility. May damage the unborn child.
• H360FdMay damage fertility. Suspected of damaging the unborn child.
• H361dSuspected of damaging the unborn child.
• H361fSuspected of damaging fertility.
