Aquatic hazard and disposal

Aquatic hazard classification (H410) for CAS 7440-43-9 reaches beyond the label. It governs the environmental section of the safety data sheet, the disposal route stated in section 13, and in several Member States the reporting threshold for storage. Consignments carrying an aquatic hazard also attract marine pollutant marking when moved by sea.

Target organ toxicity in the sheet

Specific target organ toxicity (H372) obliges the sheet to state the route of exposure and, where established, the organ affected. This is one of the few places where a generic phrase is treated as a defect rather than as caution: an unspecified organ leaves the downstream user unable to build an exposure scenario.

What must the label for cadmium (pyrophoric) contain?

The supply label for cadmium (pyrophoric) is generated from the same classification that drives the safety data sheet: pictograms selected by precedence, one signal word derived from the highest hazard class present, and the hazard statements H250, H350, H341… reproduced in full. Where the container is too small to carry the complete set at a legible size, there are lawful ways to handle it and unlawful ones that look identical to a non-specialist.

What is the CLP classification of cadmium (pyrophoric)?

The harmonised classification for CAS 7440-43-9 carries 7 hazard statements: H250, H350, H341, H361fd, H330, H372, H410. In plain terms this means H250; may cause cancer; suspected of causing genetic defects; H361fd. A harmonised entry is binding across the Union — an importer may not soften it, and a self-classification that diverges from it will not survive an enforcement check.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 7440-43-9 written before the amendment that touched its entry keeps stating a classification the register no longer holds. Nothing in the document announces this — it reads exactly as it did on the day it was issued, which is precisely why revision dates are checked before content.

Is cadmium (pyrophoric) on the SVHC candidate list?

Yes — cadmium (pyrophoric) appears on the candidate list of substances of very high concern (added 2012-12-19, reason: CMR). That triggers duties that classification alone does not: notification to ECHA above the tonnage threshold, and an obligation to inform recipients where the substance is present in an article above 0.1 % by weight. Outside the Union the same substance appears on AICS (AU), DSL_TOXIC (CA). Exporters are read against the list of the destination, not of the origin.

How do I check if my SDS for cadmium (pyrophoric) is still valid?

If a sheet for cadmium (pyrophoric) is already in circulation, the useful first question is not whether to replace it but whether it is wrong, and if so in which section. Defects repeat across a catalogue, so three documents usually reveal what three hundred need.

What happens if a consignment of cadmium (pyrophoric) is refused?

When a shipment of cadmium (pyrophoric) is detained, the expense is typically not the document itself. It is the storage costs, demurrage fees, and the delay incurred by the customer. This financial calculation underscores the importance of verifying the documentation prior to dispatch rather than after receiving a notification from the border.

Is cadmium (pyrophoric) classified as a CMR substance?

CAS 7440-43-9 is classified as a CMR substance (H350). That status changes the obligations attached to every shipment: workplace exposure documentation, restrictions on supply to the general public, and substitution pressure from downstream users who must justify continued use. A safety data sheet for a CMR substance is read more closely than any other, because the classification itself invites scrutiny.

How is cadmium (pyrophoric) classified for road, sea and air transport?

Section 14 for CAS 7440-43-9 carries the UN number, proper shipping name, class, packing group and environmental hazard where these apply. Where the substance is not dangerous for carriage, the section says so explicitly rather than being left empty — an empty section 14 reads as an omission, not as an absence of hazard.

Storage and handling in the document

Storage requirements for cadmium (pyrophoric) must be addressed in Section 7 and should align with Section 10, which outlines prohibited conditions and materials. If discrepancies arise between the two sections, the documentation is considered internally inconsistent, and a laboratory auditor will deem both sections unreliable.

What is the EC number for cadmium (pyrophoric)?

Alongside CAS 7440-43-9, this substance carries EC number 231-152-8 and Annex VI index 048-011-00-X. European documentation is built around the EC number as often as around the CAS: registration dossiers, the candidate list and customs systems key on it. A safety data sheet quoting only one of the two forces every downstream reader to look up the other.

Stability, reactivity and incompatibilities

Reactivity information for CAS 7440-43-9 in section 10 has to be specific enough to act on. ‘Avoid strong oxidising agents’ is a category; naming the classes that actually react is an instruction.

Which GHS pictograms apply to cadmium (pyrophoric)?

The label for cadmium (pyrophoric) carries GHS02 (flame), GHS06 (skull and crossbones), GHS08 (health hazard), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 7440-43-9, and the precedence rules in Annex I decide which pictogram is dropped when two would say the same thing. A label showing a different set from the register is wrong even if every hazard statement on it is correct.

Accidental release and containment

Emergency procedures for cadmium (pyrophoric) are designed for immediate action during an incident, with section 6 focusing on efficiency: outlining what should be evacuated, what materials are appropriate for containment, and which substances must not be used in the process.

Identifiers that must agree

This substance is identified by three specific codes: the CAS number 7440-43-9, the Annex VI index number 048-011-00-X, and the name listed in the register. It is essential that these identifiers match, as any discrepancy represents the most subtle error in documentation. While individual documents may appear correct on their own, cross-verification can reveal that they refer to different entities.

Is cadmium (pyrophoric) a controlled substance?

Storage requirement on record: Annex XVII entry 23: cadmium and its compounds restricted in plastics, brazing fillers, jewellery; CMR Cat. 1B. None of this appears in the CLP classification, so a sheet built from Annex VI alone will be silent on it.

Documentation demand on the EU market

CAS 7440-43-9 has a recorded presence on the European trading market, which means documentation for it is requested routinely rather than exceptionally. Substances that move in commerce attract repeat scrutiny: the same sheet is read by successive customers, carriers and authorities, and a defect that survives the first reading rarely survives the tenth.

Questions about documentation for cadmium (pyrophoric)

What hazard statements apply to CAS 7440-43-9?

The harmonised entry lists H250, H350, H341, H361fd. These are binding across the Union and may not be softened by a self-classification.

In which language must the sheet be supplied?

In an official language of each Member State where cadmium (pyrophoric) is placed on the market, unless that State has stated otherwise.

Can I check whether my existing sheet is still valid?

Yes. A section-by-section reading against Annex II and the current harmonised entry establishes that in one pass, and a sheet that passes is reported as passing.

Do I need a safety data sheet to import cadmium (pyrophoric) into the EU?

Yes. A sheet compiled to Annex II of REACH must exist before the first consignment moves, and it must be held by the entity placing the substance on the Union market.
