sulphuric acid … % (CAS 7664-93-9) — Safety Data Sheet

Safety data sheet documentation for sulphuric acid … % (CAS 7664-93-9), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H314). Two options: a working draft sent by e-mail immediately, or a signed card issued within 72 hours of complete input. The item supplied is a document — MolGod.org does not sell, supply or ship chemical substances.

Free, and generated automatically from the sources listed on this page. No person has reviewed it, and it describes the substance in general — not your material, your process or your intended market.

What you receive — and what this is not

What you receive

  • A digital PDF safety data sheet in the sixteen-section structure of REACH Annex II (Regulation 1907/2006).
  • Substance identification, hazard classification, physicochemical, toxicological and ecological information, and regulatory references.
  • Classification read against the harmonised entry in CLP Annex VI where one exists for the substance.
  • A version number, a compilation date, and the source behind each value that carries one.
  • Delivery by e-mail. Nothing is shipped.

What this is not

  • Not a chemical substance, not a sample, not any physical goods.
  • Not a certification. No official certification scheme for safety data sheets exists in the European Union.
  • Not legal approval, and not a guarantee of compliance in any jurisdiction.
  • Not a substitute for your own regulatory assessment, nor for the safety data sheet supplied by the manufacturer or importer of the substance you actually hold.
  • Not adapted to a specific workplace, process or national annex unless you provide that information.

Where the available evidence does not support a value, the sheet states that the value is not established rather than estimating one. A field with no recorded source is marked as such.

What is in the buyer pack

Everything your compliance officer will ask for, in one file.

  • The product page as PDF — the record as published, so what you forward matches what you read.
  • The safety data sheet at your entitlement level — sixteen sections in the order set by REACH Annex II, for this substance, in the language you select.
  • The CLP label artwork — generated from the same classification as the sheet, so the two cannot disagree.
  • The specification, and the certificate of analysis where batch data exists.
  • sources.txt — every citation with the date it was read.
  • An explicit list of what we could not establish — fields marked unavailable rather than filled with an estimate. This is the honest part of the document and we do not hide it in a footnote.

Your European buyer is going to forward this to somebody who was not on the call. The pack exists so that what they forward is complete, self-explanatory and traceable — rather than four attachments and a sentence beginning “I think this is everything”.

These switch the language of this page. Single substances. Mixtures on enquiry. One document, one language — additional languages are priced separately. Every version, including the Chinese one, is written to EU law — (EC) No 1907/2006 (REACH) Annex II and (EU) 2020/878 — and translated from it. The Chinese version is a reference translation, not a legally valid document for the Chinese market: an SDS for China must be compiled separately to GB/T 16483 and GB/T 17519.

About the downloads (Type of data: Predicted (calculated by nmrshiftdb2, not measured) — inferred: the source file carries no deposited measurement)
JCAMP: the NMRShiftDB file as received (JCAMP-DX 5.01 text). It is a peak list: chemical shift in ppm. MolGod adds header lines stating the type of data; the values are unchanged.
CSV: the same peak list in two columns. The second column repeats the shift value; it is not a signal intensity. Lines starting with # state the type of data.
PNG: a picture of the plot above, with the type of data written on it.
Use: where signals are expected or were reported (chemical shift positions). Not included or guaranteed: intensities, multiplicities, coupling constants, line shapes, and solvent or temperature unless stated. A predicted list is not a measurement and cannot serve as a reference spectrum for identity or purity testing. Downloads become active after Show.

Why this page can be checked

Identity

CAS, EC and molecular formula, resolved across the identifier systems a buyer uses. The count of systems resolved is shown, so you can see how well characterised this substance is rather than assuming.

Data

Every physicochemical value carries the source it came from and the date that source was read. Open any of them.

Classification

Read against the harmonised entry where one exists, with the index number stated. Self-classification is shown separately and labelled.

Regulatory

Inventory, restriction, authorisation and candidate-list status, each stated individually. Where a status is not established, this page says so — it never says no restrictions apply.

Documentation

Which documents exist, at what review level, in which languages, and when each was issued.

Supplier

Who is selling this, and what they have published about themselves.

Nothing on this page is a certification. It is a record you can audit.

Two guarantees, both with their limits stated

The Gap Report Guarantee

If the available evidence cannot support a defensible document for your CAS number and product specification, we will not invent the missing values. You receive a documented gap report and choose: a refund, store credit, or the report on its own.

A visible gap is worth more than a plausible number, because the plausible number is the one that fails when somebody checks it.

The Re-issue Promise

If a signed card is rejected by an authority or by a customer’s compliance officer on one of the points we checked and reported as passed, we re-issue it corrected at no charge and credit the original fee.

This covers the checks we performed and named. It does not cover registration status, tonnage, or your role in the supply chain — those are not ours to hold, and a guarantee that pretended otherwise would be worth nothing.

  • What is supplied – a document. MolGod.org does not sell, supply or ship chemical substances.

Can I import sulphuric acid … % into the EU?

The introduction of sulphuric acid … % 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 016-020-00-8 establishes the classification that Section 2 must reflect accordingly.

What concentration limits apply to sulphuric acid … %?

The harmonised entry for sulphuric acid … % carries specific concentration limits: H314: C ≥ 15 %; H315: 5 % ≤ C < 15 %; H319: 5 % ≤ C < 15 %. These override the generic cut-off values, so a mixture containing sulphuric acid ... % is classified against these figures and not against the default thresholds.

Published sources behind the data

The toxicological and physicochemical record for sulphuric acid … % rests on published literature, not on a supplier summary. One of the canonical references is Roebuck, J. (1746), “Lead chamber process for sulfuric acid”, Birmingham, UK (industrial). Where a value in the sheet comes from a specific paper, the sheet says which paper — a reviewer can then check one number without re-reading the whole document.

Who is responsible for REACH compliance for sulphuric acid … %?

The responsibility for documentation accompanying sulphuric acid … % rests with the entity introducing it into the Union market, rather than with any external supplier. Importers share the same obligations as manufacturers, including designating a identifiable EU contact in section 1. A non-EU supplier may appoint a sole representative, but this appointment must be established prior to the movement of goods, not in response to subsequent inquiries.

What must the label for sulphuric acid … % contain?

The supply label for sulphuric acid … % 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 H314 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 sulphuric acid … % classified for road, sea and air transport?

Carriers and forwarders handling sulphuric acid … % compare section 14 against the shipping papers before loading. Any disagreement stops the consignment at the point where correcting it is most expensive.

What Annex VI notes and concentration limits apply to sulphuric acid … %?

The Annex VI entry for CAS 7664-93-9 carries note B. 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. The register also records Skin Corr. 1A;H314: C ≥ 15.0%;Skin Irrit. 2;H315: 5.0% ≤ C < 15.0%;Eye Irrit. 2;H319: 5.0% ≤ C < 15.0% 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.

What is the UN number for sulphuric acid … %?

For carriage, sulphuric acid … % is assigned UN 1830, transport class 8, 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 is the EC number for sulphuric acid … %?

Alongside CAS 7664-93-9, this substance carries EC number 231-639-5 and Annex VI index 016-020-00-8. 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.

Which GHS pictograms apply to sulphuric acid … %?

The label for sulphuric acid … % carries GHS05 (corrosion), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 7664-93-9, 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.

Where is regulatory status recorded for sulphuric acid … %?

Whether CAS 7664-93-9 carries obligations beyond classification — candidate list entry, authorisation, restriction — belongs in section 15. Customers increasingly request a written statement on this point before placing an order, and the sheet is the natural place for it.

Identifiers that must agree

Three identifiers travel with this substance and all three have to agree: CAS 7664-93-9, the Annex VI index number 016-020-00-8, and the name as it appears in the register. Mismatched identifiers are the quietest defect in a documentation set, because every individual document looks correct and only a cross-check reveals that they describe different things.

Storage and handling in the document

Storage requirements for sulphuric acid … % belong in section 7 and have to be reconcilable with section 10, which lists conditions and materials to avoid. Where the two disagree, the sheet is internally inconsistent and a laboratory auditor will treat both as unreliable.

Stability, reactivity and incompatibilities

Incompatibilities for sulphuric acid … % belong in section 10 and must not contradict the storage guidance in section 7. Where a sheet lists a material as incompatible in one section and acceptable in another, the document has stopped being usable.

What is the CLP classification of sulphuric acid … %?

The harmonised classification for CAS 7664-93-9 carries 1 hazard statement: H314. In plain terms this means causes severe skin burns and eye damage. 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 sulphuric acid … %

What hazard statements apply to CAS 7664-93-9?

The harmonised entry lists H314. 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 sulphuric acid … % 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 sulphuric acid … % 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 the signature means

Who prepares the document
The document is generated by the MolGod engine from ECHA CLP Annex VI and the cited public sources, then read section by section by a qualified scientific reviewer with a degree in chemistry or a related scientific field.
What the review covers
The sheet is read section by section against the REACH Annex II structure. GHS classification and transport entries are checked against the sources cited in the document, and the sheet is adapted to the company, product grade and identified use you provide.
What is NOT verified
We do not test your material and we cannot confirm what is physically in your container: composition, concentration, impurities or manufacturing route. Those come from you and are reproduced as supplied.
What the signature is — and is not
The signature records that a qualified scientific reviewer read the document. It is not a government approval, not an ECHA approval, and not a legal certification — no such certification exists for safety data sheets in the EU. A signature does not by itself make a document legally valid or make your business compliant.
What you receive
A PDF in the 16-section REACH Annex II structure, signed and dated, with version information and a list of anything we could not establish. Five rounds of corrections are included.
Delivery
Within 72 hours of receiving complete input from you. The clock pauses whenever we are waiting on an answer.
Refunds
Full refund before review begins. If the evidence is insufficient, you choose a refund, store credit or a gap report. See the refund policy.

No fabricated-data guarantee. If the available evidence is insufficient to support a defensible document for this CAS number and your product specification, we will not invent the missing values. You may choose a refund, store credit or a documented gap report.

The supplier placing the substance or mixture on the market remains responsible for ensuring that the final safety data sheet matches the material, its identified uses and their legal role in the supply chain.
