Methodology
How the CLP Label Element Checker resolves required label elements, and what it does NOT certify.
What this tool resolves
For each combination of (hazard classes, pack volume, destination markets, sale context, rules regime, supplier-in-EU, is-mixture) the tool maps the inputs onto: required pictograms (Annex V), signal word (Annex I §1.2), hazard statements H (Annex III), precautionary statements P (Annex IV), required language stack (Article 17(2) + Member State language acts), pictogram minimum side and area (Annex I §1.2.1), label minimum dimensions (Annex I §1.2.1), font minimum x-height + line spacing (Reg (EU) 2024/2865, applicable from 1 Jan 2028).
What this tool does NOT do
It does not perform CLP classification (you must supply the hazard class + category codes already determined from Annex I or supplier SDS). It does not certify compliance — only a qualified person can sign off label artwork. It does not draft the actual H/P statement text (the codes resolve to ECHA-published phrases via the standard Annex III/IV lookup; this tool emits the codes and expects your DTP toolchain to inject the localised phrases). It is not legal advice.
Pre-2028 vs from-2028 regime
The "current" regime applies the pre-Reg 2024/2865 baseline: pictogram side ≥1.6 cm² area or label_clp_info_area_cm² / 15 (whichever is greater), no quantitative font minimum, no quantitative line-spacing minimum. The "from-2028 voluntary now" regime applies Reg (EU) 2024/2865 Annex VIII §1.2.1.4: font x-height ≥1.4 mm for pack volume <3 l, ≥1.8 mm for 3–50 l, ≥2.0 mm for 50–500 l, ≥2.4 mm for >500 l; line spacing ≥120% of font x-height; pictogram minimum side as in Annex I §1.2.1.
Small-package exemption (≤125 ml)
Annex I §1.5.2.1.1 permits partial omission of H/P statements for packs ≤125 ml when ALL hazard classes are within the eligible categories (Acute Tox. 4 — only inhalation; Skin Irrit. 2; Eye Irrit. 2; STOT-SE 3; Aquatic Chronic 3/4; Aquatic Acute 1; Oz Layer 1). If any hazard class falls outside this list, no exemption applies — full labelling is required. The tool never blanket-omits: it lists the specific H/P codes eligible for omission.
Language stack derivation
Article 17(2) requires the label in the official language(s) of every Member State where the product is placed on the market. The tool unions the official languages of the destination markets: BE = nl+fr+de; LU = fr+de+lb; FI = fi+sv; IE = en+ga; MT = mt+en; CY = el (en optional per CA); single-language MS contribute their single official language.
1 July 2026 supplier-in-EU requirement
Reg (EU) 2024/2865 Article 4(10) takes effect 1 July 2026: the supplier identified on the label must be established in the EU, or an EU-established responsible person must be identified. If you mark "supplier not established in EU" and the tool's compute date is ≥ 2026-07-01, the spec emits a red compliance-blocker notice.
Dataset freshness
All regulatory thresholds (pictogram dimensions, label dimensions, font minima, eligible hazard categories for small-package omission, official language map per MS) are versioned in src/lib/dataset.ts with a `last_verified` date. If the dataset is older than 90 days the tool emits a staleness banner — re-verify before relying on the spec.
