Which GHS pictograms apply to benomyl (ISO)?

The label for benomyl 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 17804-35-2, 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.

What is the CLP classification of benomyl (ISO)?

The harmonised classification for CAS 17804-35-2 carries 7 hazard statements: H340, H360FD, H335, H315, H317, H400, H410. In plain terms this means may cause genetic defects; may damage fertility and the unborn child; may cause respiratory irritation; causes skin irritation. 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.

Documentation demand on the EU market

CAS 17804-35-2 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.

What must the label for benomyl (ISO) contain?

The supply label for benomyl (ISO) 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 H340, H360FD, H335… 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 do customs check when importing benomyl (ISO)?

When a consignment of benomyl (ISO) 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 17804-35-2 will hold the pallet regardless of how complete the remaining fifteen sections are.

What is the EC number for benomyl (ISO)?

Alongside CAS 17804-35-2, this substance carries EC number 241-775-7 and Annex VI index 613-049-00-3. 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.

Accidental release and containment

Emergency procedures for benomyl 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.

First-aid content and why it is read first

First-aid content for CAS 17804-35-2 has to be actionable by a person who is not a chemist and is reading under pressure. Section 4 also carries notes for the attending physician, which is where the classification becomes clinically relevant.

Other names for this substance

The same substance appears in trade and in the literature under several names: methyl 1-(butylcarbamoyl)benzimidazol-2-ylcarbamate. A safety data sheet has to carry the name used in the harmonised entry, but a purchase order, a customs declaration and a certificate of analysis may each use a different one. Where the names diverge, CAS 17804-35-2 is the identifier that reconciles them — and a document set that relies on trade names alone will eventually be read as describing three different materials.

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 17804-35-2 number or if the index 613-049-00-3 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.

How is benomyl (ISO) classified for road, sea and air transport?

The transport classification for benomyl 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.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 17804-35-2 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.

Stability, reactivity and incompatibilities

Section 10 records stability and reactivity for benomyl: conditions to avoid, incompatible materials, and hazardous decomposition products. This is the section a laboratory consults before placing two substances on the same shelf.

What concentration limits apply to benomyl (ISO)?

M-factor on record: 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.

Where is regulatory status recorded for benomyl (ISO)?

Section 15 records regulatory status for benomyl: whether it appears on the candidate list, whether it is subject to authorisation or restriction, and any national provisions. Downstream users ask this question routinely, and a sheet that answers it saves an exchange of emails per customer.

Purity, certificates and what the sheet does not say

For CAS 17804-35-2 the distinction between grades — technical, reagent, analytical — lives in the certificate of analysis and in the specification it is measured against, not in the safety data sheet. Confusing the two is the most common documentation error we see in laboratory procurement.

What Annex VI notes and concentration limits apply to benomyl (ISO)?

The register also records 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 benomyl (ISO) classified as a CMR substance?

CAS 17804-35-2 is classified as a CMR substance (H340, H360FD). 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.

Questions about documentation for benomyl

In which language must the sheet be supplied?

In an official language of each Member State where benomyl 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 benomyl 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 benomyl?

CAS 17804-35-2. In CLP Annex VI the same substance carries index number 613-049-00-3, and both identifiers should appear in the documentation.
