Is ammonia, anhydrous on the SVHC candidate list?

Outside the Union the same substance appears on TSCA (US). Exporters are read against the list of the destination, not of the origin.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 7664-41-7 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.

Documentation demand on the EU market

CAS 7664-41-7 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 Annex VI notes and concentration limits apply to ammonia, anhydrous?

The Annex VI entry for CAS 7664-41-7 carries note U. 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.

Can I import ammonia, anhydrous into the EU?

The import of CAS 7664-41-7 is deemed successful or unsuccessful depending on whether the accompanying document aligns with the register entry. Among substances listed in CLP Annex VI, a frequent issue arises from classification inherited from a supplier outside the Union, where the same substance may be classified differently. The definitive reference is index 007-[CAS?], and discrepancies emerge in regulated consignments.

Purity, certificates and what the sheet does not say

A laboratory receiving ammonia, anhydrous from its supplier must ensure that two documents agree: the substance’s safety data sheet and the batch certificate for the material in hand. Discrepancies in identity or supplier details between these documents render both questionable. MolGod facilitates the preparation and audit of these documents, while the material itself is sourced from your supplier.

Who is responsible for REACH compliance for ammonia, anhydrous?

The obligation attached to ammonia, anhydrous 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.

What must the label for ammonia, anhydrous contain?

The supply label for ammonia, anhydrous 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 H221, H331, 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.

What is the CLP classification of ammonia, anhydrous?

The harmonised classification for CAS 7664-41-7 carries 4 hazard statements: H221, H331, H314, H400. In plain terms this means H221; toxic if inhaled; causes severe skin burns and eye damage; 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.

Aquatic hazard and disposal

Aquatic hazard classification (H400) for CAS 7664-41-7 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.

Storage and handling in the document

Section 7 of the documentation for ammonia, anhydrous details handling and storage procedures, including incompatible materials, conditions to be avoided, and any segregation requirements resulting from its classification. Laboratories reviewing this section need explicit instructions rather than general warnings; for example, a statement like ‘store in a cool dry place’ is insufficient because it leaves the responsibility of specifying precise storage conditions to the personnel.

Which GHS pictograms apply to ammonia, anhydrous?

The label for ammonia, anhydrous carries GHS04 (gas cylinder), GHS05 (corrosion), GHS06 (skull and crossbones), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 7664-41-7, 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.

How do I check if my SDS for ammonia, anhydrous is still valid?

If a sheet for ammonia, anhydrous is already in circulation, the useful first question is not whether to replace it but whether it is wrong, and if so in which section. Defects repeat across a catalogue, so three documents usually reveal what three hundred need.

What is the UN number for ammonia, anhydrous?

For carriage, ammonia, anhydrous is assigned UN 2672, transport class 8, packing group III. 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.

How is ammonia, anhydrous classified for road, sea and air transport?

Section 14 for CAS 7664-41-7 includes the UN number, correct shipping name, class, packing group, and environmental hazard where applicable. If the substance is not hazardous for transportation, Section 14 explicitly states this rather than being left empty; an empty Section 14 is interpreted as an omission rather than a lack of hazard.

What is the EC number for ammonia, anhydrous?

Alongside CAS 7664-41-7, this substance carries EC number 231-635-3 and Annex VI index 007-[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.

Which SDS sections decide whether a shipment clears?

The sixteen sections prescribed by Annex II are not a formatting convention; each carries a defined content and an inspector reads them by number. For CAS 7664-41-7 the sections that usually decide acceptance are 2 (classification against the harmonised entry), 3 (composition and identifiers), 14 (transport) and 15 (regulatory status). Sections may not be merged, renumbered or left with a placeholder.

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 7664-41-7 number or if the index 007-[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.

Questions about documentation for ammonia, anhydrous

Do I need a safety data sheet to import ammonia, anhydrous 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 ammonia, anhydrous?

CAS 7664-41-7. In CLP Annex VI the same substance carries index number 007-[CAS?], and both identifiers should appear in the documentation.

What hazard statements apply to CAS 7664-41-7?

The harmonised entry lists H221, H331, H314, 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 ammonia, anhydrous 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 7664-41-7 identifies the subject of this document.
