First-aid content and why it is read first

The first-aid information for CAS 107-06-2 must be understandable and actionable by someone without a chemistry background when following instructions under time pressure. Section 4 includes additional notes intended for medical professionals, where the classification’s clinical relevance is detailed.

How is 1,2-dichloroethane classified for road, sea and air transport?

Section 14 for CAS 107-06-2 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 must the label for 1,2-dichloroethane contain?

The supply label for 1,2-dichloroethane 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 H225, H350, H302… 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.

Who is responsible for REACH compliance for 1,2-dichloroethane?

Whoever brings 1,2-dichloroethane 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.

Documentation demand on the EU market

CAS 107-06-2 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 do customs check when importing 1,2-dichloroethane?

When a consignment of 1,2-dichloroethane 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 107-06-2 will hold the pallet regardless of how complete the remaining fifteen sections are.

Is 1,2-dichloroethane on the SVHC candidate list?

Yes — 1,2-dichloroethane appears on the candidate list of substances of very high concern. That triggers duties that classification alone does not: notification to ECHA above the tonnage threshold, and an obligation to inform recipients where the substance is present in an article above 0.1 % by weight. It is also listed in Annex XIV, with a sunset date of 2017-11-22. Once a substance reaches Annex XIV, continued use in the Union requires an authorisation granted for a named use — a supplier relationship alone is not a legal basis. Outside the Union the same substance appears on DSL_TOXIC (CA), TSCA (US). Exporters are read against the list of the destination, not of the origin.

Is 1,2-dichloroethane classified as a CMR substance?

CAS 107-06-2 is classified as a CMR substance (H350). 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.

In which language must the SDS for 1,2-dichloroethane be supplied?

Language is a compliance question, not a convenience one. Wherever 1,2-dichloroethane reaches a customer, the receiving Member State may require the sheet in its own official language, and several do so without exception. An English original that satisfies an auditor in one country can be refused at the next border, with the content untouched and the fault lying entirely in which words it is written in.

Can I import 1,2-dichloroethane into the EU?

Bringing 1,2-dichloroethane into the Union is a documentation exercise before it is a logistics one. The file has to exist at the moment of import, not at the moment somebody asks for it, and for substances listed in CLP Annex VI it is examined in the context of regulated consignments. Index 602-[CAS?] fixes the classification that section 2 must reproduce.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 107-06-2 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.

Identifiers that must agree

The CAS 107-06-2 number and index number 602-[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.

Which GHS pictograms apply to 1,2-dichloroethane?

The label for 1,2-dichloroethane carries GHS02 (flame), GHS07 (exclamation mark), GHS08 (health hazard), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 107-06-2, 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 EC number for 1,2-dichloroethane?

Alongside CAS 107-06-2, this substance carries EC number 203-458-1 and Annex VI index 602-[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.

Purity, certificates and what the sheet does not say

For CAS 107-06-2 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.

How do I check if my SDS for 1,2-dichloroethane is still valid?

If a document concerning 1,2-dichloroethane is already in circulation, the initial consideration should be whether it is incorrect rather than whether to replace it, and if incorrect, in which specific sections. Errors tend to recur across a range of documents; therefore, examining three documents often provides insights that would otherwise require reviewing three hundred.

Accidental release and containment

Section 6 covers accidental release of 1,2-dichloroethane: personal precautions, environmental precautions and the containment method. Where the classification carries an aquatic hazard, the environmental part stops being a formality and becomes the operative instruction.

What is the CLP classification of 1,2-dichloroethane?

The harmonised classification for CAS 107-06-2 carries 6 hazard statements: H225, H350, H302, H335, H315, H319. In plain terms this means highly flammable liquid and vapour; may cause cancer; harmful if swallowed; may cause respiratory 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.

Questions about documentation for 1,2-dichloroethane

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 1,2-dichloroethane 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 1,2-dichloroethane?

CAS 107-06-2. In CLP Annex VI the same substance carries index number 602-[CAS?], and both identifiers should appear in the documentation.

Is 1,2-dichloroethane a CMR substance?

Yes. The harmonised classification places it among substances classified as carcinogenic, mutagenic or toxic for reproduction, which changes workplace documentation and supply restrictions.
