| Safety data sheet (SDS) | Sections reordered or shortened – the SDS is no longer REACH-compliant and placing on the market becomes challengeable. | Fixed structure of 16 sections under REACH Annex II (Art. 31); the national language of every supply state. |
| H and P statements | Hazard and precautionary statements are paraphrased – and lose their legal validity. | H/P statements in the official wording from CLP (Reg. (EC) 1272/2008) – never translated freely. |
| Hazard vs. precautionary statements & signal word | "Danger" and "Warning" swapped, or H mixed with P statements – hazard communication breaks down. | Signal word, H statements (Hazard) and P statements (Precautionary) kept cleanly separate and standardised. |
| INN active-substance names | Brand name instead of the active substance, or mistranscribed – the substance is no longer uniquely identifiable. | INN per WHO unchanged; language variants (e.g. -in/-ine) set correctly. |
| CAS/EC numbers | Digits "translated along", reordered or separators changed – the substance is no longer traceable in any register. | CAS, EC (EINECS/ELINCS) and index numbers carried over character-for-character. |
| EMA QRD templates (SmPC/package leaflet) | Freely worded instead of standard sentences – submission is delayed or rejected. | Wording and structure to the EMA's QRD template; standard phrasing carried over. |
| Units, concentrations, decimal separators | German comma and English point swapped (1,5 ↔ 1.5) – a dose turns into a dosing error. | Target convention checked; mg/kg, %, ppm and dilutions kept consistent. |
| IUPAC nomenclature | Trivial name instead of the systematic name, locants or stereodescriptors slipped – a different substance. | Systematic IUPAC names; locants and (R/S, E/Z) descriptors preserved. |
