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 H413?
For a pure substance H413 comes straight from the classification; for a mixture it is derived from component data. The calculation rules applied to this code are:
- A component of this class is taken into account in a mixture only at a concentration of ≥ 1 %. (CLP Annex I Table 1.1)
- Summation method: the weighted sum of the qualifying components must reach ≥ 25 % for the mixture to be classified Aquatic Chronic 4 (H413). (CLP Annex I Table 4.1.2; 4.1.3.5.5.4.5)
- 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 H413 written in the SDS?
In the prepared SDS the class "Aquatic Chronic 4" is matched with the code in Section 2.1, the text of H413 is written in Section 2.2 next to the pictogram and signal word, and the class of the component shows up in Section 3. Section 16 collects the full text of the H statements cited by code. For H413, it is justified in Section 12 (ecological information) under the relevant effect heading.
How does H413 appear on the label?
When you see H413 on a label it is accompanied by no pictogram, and it needs no signal word. 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, 2 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 H413 are given together.
- Section 2.2: label elements; H413 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 H413
The values below come from the Chemoris rule file (CLP Annex I). They show the condition under which H413 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.
| Class | Criterion | Limit / formula | Source |
|---|---|---|---|
| Aquatic Chronic 4 | Minimum concentration for a component to be considered | ≥ 1 % | CLP Annex I Table 1.1 |
| Aquatic Chronic 4 | Additive formula by which a mixture reaches this class | Σ(Aquatic Chronic 1/2/3/4) ≥ 25 % | CLP Annex I Table 4.1.2; 4.1.3.5.5.4.5 |
H413 compared with H412 and H411
The table below puts H413 next to its closest neighbouring statements; the values are read from the rule data.
| Hazard statement | H413 | H412 | H411 |
|---|---|---|---|
| Class abbreviation | Aquatic Chronic 4 | Aquatic Chronic 3 | Aquatic Chronic 2 |
| Pictogram | none | none | GHS09 |
| Signal word | — | — | — |
| Precautionary statements assigned | 2 | 2 | 3 |
| Concentration cut-off in a mixture | 1 % | 1 % | 1 % |
H413 and H412 carry the same signal word (—). Both are shown with the same pictogram (none). H413 and H411 carry the same signal word (—). The pictogram differs: none for H413, GHS09 for H411.
In which SDS sections does H413 appear?
H413 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.
| SDS section | Relation to this code |
|---|---|
| 2.1 Classification | Written with the abbreviation Aquatic Chronic 4 and the code H413. |
| 2.2 Label elements | H413 appears with its full text, none and none. |
| 3 Composition | The class and code show in the row of every component that carries this class. |
| 12 Ecological information | The aquatic or environmental effect is justified here. |
| 7 Handling and storage | Of the 2 assigned P statements, 1 belong to the subject of this section: P273. |
| 13 Disposal | Of the 2 assigned P statements, 1 belong to the subject of this section: P501. |
| 16 Other information | The full text of the H statements cited by code is collected here. |
Statements that appear on the label together with H413
H413 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 2 candidates for this class:
| Rank | P code | Type | Priority | Text |
|---|---|---|---|---|
| 1 | P273 | prevention | core | Avoid release to the environment. |
| 2 | P501 | disposal | core | Dispose of contents/container to … |
The none pictogram and none 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 H413 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)).
