Which SDS sections decide whether a shipment clears?

The sheet for CAS 13463-41-7 must be read numerically rather than narratively; subsections carry the same weight as sections: an inspector seeking information under point 3.1 will not accept data presented within a paragraph elsewhere, regardless of that paragraph’s completeness. Completeness is initially assessed by structure, followed by content evaluation.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 13463-41-7 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.

What Annex VI notes and concentration limits apply to pyrithione zinc?

The register also records inhalation: ATE = 0.14 mg/L dusts or mists;oral: ATE = 221.0 mg/kg bw;M = 1000;M = 10 for this entry. Specific concentration limits, M-factors and acute toxicity estimates override the generic cut-off values, so a mixture calculation that ignores them will classify the mixture wrongly in both directions.

Is pyrithione zinc classified as a CMR substance?

CAS 13463-41-7 is classified as a CMR substance (H360D). 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.

Who is responsible for REACH compliance for pyrithione zinc?

Whoever brings pyrithione zinc across the Union border carries the documentation duty, and it does not transfer back up the supply chain by contract. Section 1 has to name a contactable entity inside the Union: a foreign address there is treated as no address at all, and it is among the first things an inspector verifies because it takes seconds.

Can I import pyrithione zinc into the EU?

Introducing pyrithione zinc 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, heterocyclic compounds is evaluated within the context of active-ingredient and intermediate imports. Index 613-[CAS?] establishes the classification that Section 2 must mirror accordingly.

What concentration limits apply to pyrithione zinc?

M-factors on record: 1000; 10. The M-factor multiplies the contribution of this substance in the aquatic hazard calculation for a mixture, which is where it is most often overlooked. Acute toxicity estimates stated in the register: inhalation: ATE = 0,14 mg/L; oral: ATE = 221 mg/kg.

In which language must the SDS for pyrithione zinc be supplied?

A safety data sheet must be supplied in an official language of every Member State where pyrithione zinc 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 it can be used universally. A sheet in the incorrect language constitutes sufficient grounds for rejection, regardless of its accuracy.

What must the label for pyrithione zinc contain?

The supply label for pyrithione zinc 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 H360D, H330, H301… 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.

How is pyrithione zinc classified for road, sea and air transport?

Transport classification for pyrithione zinc 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.

Where is regulatory status recorded for pyrithione zinc?

Regulatory status for pyrithione zinc changes independently of its hazard classification. A substance can keep the same hazard profile for years and acquire new obligations in section 15, which is why that section dates faster than section 2.

How do I check if my SDS for pyrithione zinc is still valid?

Before ordering documentation for pyrithione zinc, 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.

Identifiers that must agree

The CAS 13463-41-7 number and index number 613-[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 pyrithione zinc?

Alongside CAS 13463-41-7, this substance carries EC number 236-671-3 and Annex VI index 613-[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.

Protective equipment and exposure controls

Laboratories building a risk assessment for pyrithione zinc start from section 8. Where an occupational exposure limit exists it must be stated with its source and averaging period; where none exists, the sheet says so rather than leaving the field blank.

What is the CLP classification of pyrithione zinc?

The harmonised classification for CAS 13463-41-7 carries 7 hazard statements: H360D, H330, H301, H372, H318, H400, H410. In plain terms this means may damage the unborn child; fatal if inhaled; toxic if swallowed; causes damage to organs through prolonged or repeated exposure. 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.

Which GHS pictograms apply to pyrithione zinc?

The label for pyrithione zinc carries GHS05 (corrosion), 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 13463-41-7, 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.

Stability, reactivity and incompatibilities

Reactivity information for CAS 13463-41-7 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.

Questions about documentation for pyrithione zinc

In which language must the sheet be supplied?

In an official language of each Member State where pyrithione zinc 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 pyrithione zinc 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.

What is the CAS number of pyrithione zinc?

CAS 13463-41-7. In CLP Annex VI the same substance carries index number 613-[CAS?], and both identifiers should appear in the documentation.

MolGod.org issues documentation and does not sell, supply or ship chemical substances. CAS 13463-41-7 identifies the subject of this document.
