What do customs check when importing nitric acid …% [C > 70 %]?

When a consignment of nitric acid …% [C > 70 %] 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 7697-37-2 will hold the pallet regardless of how complete the remaining fifteen sections are.

Where is regulatory status recorded for nitric acid …% [C > 70 %]?

Whether CAS 7697-37-2 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.

Storage and handling in the document

Storage requirements for nitric acid …% [C > 70 %] 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.

What Annex VI notes and concentration limits apply to nitric acid …% [C > 70 %]?

The Annex VI entry for CAS 7697-37-2 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 Ox. Liq. 3;H272: C ≥ 65.0%;inhalation: ATE = 2.65 mg/L vapours;Skin Corr. 1A;H314: C ≥ 20.0%;Skin Corr. 1B;H314: 5.0% ≤ C < 20.0% 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.

Protective equipment and exposure controls

Section 8 outlines exposure controls and personal protective equipment (PPE) for nitric acid …% [C > 70 %]: appropriate glove materials, eye protection, respiratory protection when warranted by the hazard classification, and any established occupational exposure limits. The choice of glove material is more critical than merely wearing gloves; nitrile gloves are not universally suitable.

What concentration limits apply to nitric acid …% [C > 70 %]?

The harmonised entry for nitric acid …% [C > 70 %] carries specific concentration limits: C ≤ 70 %; H272: C ≥ 65 %; H314: C ≥ 20 %; H314: 5 % ≤ C < 20 %. These override the generic cut-off values, so a mixture containing nitric acid …% [C > 70 %] is classified against these figures and not against the default thresholds. Acute toxicity estimate stated in the register: inhalation: ATE = 2,65 mg/L.

Which GHS pictograms apply to nitric acid …% [C > 70 %]?

The label for nitric acid …% [C > 70 %] carries GHS03 (flame over circle), GHS05 (corrosion), GHS06 (skull and crossbones), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 7697-37-2, 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 must the label for nitric acid …% [C > 70 %] contain?

The supply label for nitric acid …% [C > 70 %] 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, H330, 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 happens if a consignment of nitric acid …% [C > 70 %] is refused?

A rejected document is typically complete and well-formatted but may be outdated or contain an incorrect consignment identifier. When a shipment of nitric acid …% [C > 70 %] is refused, the authority’s notice usually specifies the faulty section. Examining this notice is more efficient than revisiting the entire file.

How is nitric acid …% [C > 70 %] classified for road, sea and air transport?

Carriers and forwarders handling nitric acid …% [C > 70 %] compare section 14 against the shipping papers before loading. Any disagreement stops the consignment at the point where correcting it is most expensive.

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 7697-37-2 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.

Disposal route and waste classification

Waste generated from nitric acid …% [C > 70 %] must be classified by the waste holder, but the classification sheet needs to provide the information that this classification is based on. Therefore, sections 13 and 2 are read together, and any discrepancy between them is considered a defect.

Can I import nitric acid …% [C > 70 %] into the EU?

An import of CAS 7697-37-2 is successful or unsuccessful based on whether the accompanying document matches the register entry. Among substances listed in CLP Annex VI, a common failure arises from classification carried over from a supplier outside the Union, where the same substance may be classified differently. The binding reference is index 007-[CAS?], and discrepancies occur in regulated consignments.

What is the CLP classification of nitric acid …% [C > 70 %]?

The harmonised classification for CAS 7697-37-2 carries 3 hazard statements: H272, H330, H314. In plain terms this means may intensify fire; oxidiser; fatal if inhaled; 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.

Identifiers that must agree

The CAS 7697-37-2 number and index number 007-[CAS?] are not interchangeable or decorative elements; they serve distinct purposes. The index number connects to the harmonised classification system, whereas the CAS number links to chemical literature. A document containing one without the other requires readers to independently reconstruct this relationship, which may lead to errors during reconstruction.

What is the EC number for nitric acid …% [C > 70 %]?

Alongside CAS 7697-37-2, this substance carries EC number 231-714-2 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.

What is the UN number for nitric acid …% [C > 70 %]?

For carriage, nitric acid …% [C > 70 %] is assigned UN 2031, transport class 8, packing group II, with subsidiary risk 5.1. 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 do I check if my SDS for nitric acid …% [C > 70 %] is still valid?

Before ordering documentation for nitric acid …% [C > 70 %], 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.

Questions about documentation for nitric acid …% [C > 70 %]

In which language must the sheet be supplied?

In an official language of each Member State where nitric acid …% [C > 70 %] 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 nitric acid …% [C > 70 %] 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 nitric acid …% [C > 70 %]?

CAS 7697-37-2. In CLP Annex VI the same substance carries index number 007-[CAS?], and both identifiers should appear in the documentation.
