Disposal route and waste classification

Disposal of potassium permanganate 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.

What is the CLP classification of potassium permanganate?

The harmonised classification for CAS 7722-64-7 carries 5 hazard statements: H272, H361d, H302, H400, H410. In plain terms this means may intensify fire; oxidiser; H361d; harmful if swallowed; very toxic to aquatic life. 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.

Where is regulatory status recorded for potassium permanganate?

The regulatory status of potassium permanganate evolves separately from its hazard classification. A substance may maintain consistent hazard characteristics over extended periods while gaining additional obligations under Section 15, leading to this section becoming outdated more rapidly than Section 2.

How is potassium permanganate classified for road, sea and air transport?

The transport classification for potassium permanganate falls under section 14 and varies depending on the mode of transport: ADR for road, IMDG for sea, and IATA for air. A document that prints all three classifications without specifying which one applies places the responsibility on the shipper to select the correct one, and it is the shipper who faces penalties for making an incorrect choice.

How do I check if my SDS for potassium permanganate is still valid?

Before ordering documentation for potassium permanganate, verify if the existing sheet can withstand an inspection. Conduct a section-by-section review against Annex II to determine compliance in one pass; if it meets the requirements, the honest assessment confirms its validity.

Stability, reactivity and incompatibilities

Section 10 documents the stability and reactivity of potassium permanganate, outlining specific conditions to be avoided, incompatible materials, and hazardous decomposition products. Laboratories refer to this section prior to storing two substances together on the same shelf to ensure compatibility and safety.

What is the UN number for potassium permanganate?

For carriage, potassium permanganate is assigned UN 1490, transport class 5.1, packing group II. These entries belong in section 14 of the safety data sheet and must match the shipping papers exactly. A consignment where the sheet and the transport document disagree on the UN number is stopped before anyone reads the remaining fifteen sections.

What must the label for potassium permanganate contain?

The supply label for potassium permanganate 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 H272, H361d, H302… 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.

Is potassium permanganate a controlled substance?

Storage requirement on record: Cocaine precursor (oxidation of coca paste); GHS oxidiser Cat. 2; Annex I Cat. 3 reportable above thresholds. None of this appears in the CLP classification, so a sheet built from Annex VI alone will be silent on it.

Can I import potassium permanganate into the EU?

Introducing potassium permanganate into the Union requires documentation to be prepared prior to logistics arrangements. The documentation file must already be available at the time of import, not merely upon request; for this purpose, substances listed in CLP Annex VI is evaluated within the context of regulated consignments. Index 025-[CAS?] establishes the classification that Section 2 must mirror accordingly.

Who is responsible for REACH compliance for potassium permanganate?

The obligation attached to potassium permanganate follows the act of importing, not the act of manufacturing. A distributor buying inside the Union inherits a lighter duty than one who imports directly, and confusing the two is expensive: the importer must hold the full file, while the distributor may rely on what was passed down.

Which GHS pictograms apply to potassium permanganate?

The label for potassium permanganate carries GHS03 (flame over circle), 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 7722-64-7, 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.

Identifiers that must agree

The CAS 7722-64-7 number and index number 025-[CAS?] are not interchangeable or merely decorative elements. The index number establishes a connection to the harmonised classification system, while the CAS number links the entry to the chemical literature. A document that includes one without the other necessitates that every reader independently reconstructs this relationship, and such reconstruction is where errors may occur.

What is the EC number for potassium permanganate?

Alongside CAS 7722-64-7, this substance carries EC number 231-760-3 and Annex VI index 025-[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.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 7722-64-7 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.

In which language must the SDS for potassium permanganate be supplied?

A safety data sheet must be provided in an official language of every Member State where potassium permanganate is placed on the market, unless that State has specified otherwise. This requirement is frequently overlooked by importers who possess a technically correct English document and assume its validity across borders. A sheet in the incorrect language alone constitutes grounds for refusal, irrespective of the accuracy of its content.

Protective equipment and exposure controls

Section 8 details exposure controls and personal protective equipment (PPE) for potassium permanganate: appropriate glove materials, eye protection, respiratory protection when required by the hazard classification, and any established occupational exposure limits. The selection of glove material is more important than merely wearing gloves; nitrile gloves are not universally suitable.

Aquatic hazard and disposal

Aquatic hazard classification (H400, H410) for CAS 7722-64-7 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.

Questions about documentation for potassium permanganate

What is the CAS number of potassium permanganate?

CAS 7722-64-7. In CLP Annex VI the same substance carries index number 025-[CAS?], and both identifiers should appear in the documentation.

What hazard statements apply to CAS 7722-64-7?

The harmonised entry lists H272, H361d, H302, H400. 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 potassium permanganate 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.
