How do I check if my SDS for cadmium hydroxide is still valid?

Before ordering documentation for cadmium hydroxide, it is worth establishing whether the sheet already in use would survive an inspection. A section-by-section reading against Annex II and the harmonised entry answers that in a single pass, and where it passes, the honest outcome is that it passes.

Which SDS sections decide whether a shipment clears?

The sixteen sections in Annex II are not merely a formatting requirement; each section serves a specific purpose, and inspectors evaluate them sequentially. For the CAS registry number 21041-95-2, key sections for acceptance typically include 2 (harmonised entry classification), 3 (composition and identifiers), 14 (transport) and 15 (regulatory status). It is crucial not to merge, renumber or omit any sections, as placeholders must remain unchanged.

Aquatic hazard and disposal

Aquatic hazard classification (H400, H410) for CAS 21041-95-2 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.

Identifiers that must agree

Identity verification must be conducted prior to hazard assessment. If discrepancies exist between the label, safety data sheet, and certificate regarding the CAS 21041-95-2 number or if the index 048-[CAS?] refers to a location where the name does not match, a reviewer will lose trust in all three documents simultaneously, despite their internal consistency. This is because inconsistencies among these key documentation elements undermine their reliability as a unified source of information.

What do customs check when importing cadmium hydroxide?

When a consignment of cadmium hydroxide is stopped at the border, the document examined first is rarely the invoice. It is section 14 of the safety data sheet and its agreement with the transport papers. A missing packing group, an absent UN number or a proper shipping name that contradicts the classification of CAS 21041-95-2 will hold the pallet regardless of how complete the remaining fifteen sections are.

What is the EC number for cadmium hydroxide?

Alongside CAS 21041-95-2, this substance carries EC number 244-168-5 and Annex VI index 048-[CAS?]. 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.

First-aid content and why it is read first

Section 4 details first-aid measures for cadmium hydroxide according to exposure routes: inhalation, skin contact, eye exposure, and ingestion, providing specific guidance for each scenario. The primary shortcoming is the generic advice to ‘seek medical attention’ across all four situations; this recommendation is most pertinent when immediate assistance is required.

How is cadmium hydroxide classified for road, sea and air transport?

Transport classification for cadmium hydroxide sits in section 14 and differs by mode: ADR for road, IMDG for sea, IATA for air. A sheet that prints all three without stating which applies leaves the shipper to choose, and the shipper is the one penalised for choosing wrong.

Stability, reactivity and incompatibilities

The reactivity information for CAS 21041-95-2 provided under Section 10 must be sufficiently detailed and actionable. While stating ‘avoid strong oxidizing agents’ offers a general category, specifying the exact chemical classes that react with the substance in question provides clearer guidance on appropriate handling and precautionary measures.

Can I import cadmium hydroxide into the EU?

The introduction of cadmium hydroxide into the Union necessitates the preparation of documentation prior to logistical arrangements. The documentation file must be available at the time of import, not merely upon request; for this purpose, substances listed in CLP Annex VI is assessed within the context of regulated consignments. Index 048-[CAS?] establishes the classification that Section 2 must reflect accordingly.

Disposal route and waste classification

Disposal of cadmium hydroxide and its packaging must comply with section 13 requirements. The substance is classified as posing an aquatic hazard, meaning it cannot be discharged into drains. The waste code assigned by the holder should reflect the hazard profile rather than convenience, ensuring proper management in accordance with regulatory guidelines.

Which GHS pictograms apply to cadmium hydroxide?

The label for cadmium hydroxide carries GHS07 (exclamation mark), GHS08 (health hazard), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 21041-95-2, 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.

Is cadmium hydroxide on the SVHC candidate list?

Yes — cadmium hydroxide appears on the candidate list of substances of very high concern. 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.

What Annex VI notes and concentration limits apply to cadmium hydroxide?

The Annex VI entry for CAS 21041-95-2 carries notes A, 1. Notes are not commentary: they modify how the classification applies — to concentration ranges, to specific forms of the substance, or to the labelling that follows from it. An entry read without its notes is read incompletely.

Is cadmium hydroxide classified as a CMR substance?

CAS 21041-95-2 is classified as a CMR substance (H350, H340). 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.

Accidental release and containment

Section 6 addresses the accidental release of cadmium hydroxide, outlining personal precautions, environmental precautions, and containment methods. When the classification indicates an aquatic hazard, the environmental precautions section transitions from a mere formality to a critical instruction that must be rigorously followed.

What must the label for cadmium hydroxide contain?

The supply label for cadmium hydroxide 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 H350, H340, H332… 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 hydroxide?

The harmonised classification for CAS 21041-95-2 carries 8 hazard statements: H350, H340, H332, H312, H302, H372 (kidney, bone), H400, H410. In plain terms this means may cause cancer; may cause genetic defects; harmful if inhaled; harmful in contact with skin. 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.

Questions about documentation for cadmium hydroxide

What is the CAS number of cadmium hydroxide?

CAS 21041-95-2. In CLP Annex VI the same substance carries index number 048-[CAS?], and both identifiers should appear in the documentation.

Is cadmium hydroxide a CMR substance?

Yes. The harmonised classification places it among substances classified as carcinogenic, mutagenic or toxic for reproduction, which changes workplace documentation and supply restrictions.

What hazard statements apply to CAS 21041-95-2?

The harmonised entry lists H350, H340, H332, H312. 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 hydroxide is placed on the market, unless that State has stated otherwise.

MolGod.org issues documentation and does not sell, supply or ship chemical substances. CAS 21041-95-2 identifies the subject of this document.
