Principle: no data = no claim (we do NOT declare "no restrictions" without a basis). 3 required / 12 items [fulfilled] SDS (Safety Data Sheet) available (sds) How to comply: Requirement: current SDS compliant with Reg. 1907/2006 (REACH) Annex II, 16-section format. Source / form: https://echa.europa.eu/information-on-chemicals [required] Compliant CLP label (pictograms + signal word + H/P) (clp_label) How to comply: The label must include: GHS pictograms, the signal word (Danger/Warning), hazard (H) and precautionary (P) statements, and manufacturer details. Required since 2010 (substances) and 2015 (mixtures). For this substance a HARMONISED CLASSIFICATION applies (CLP Annex VI) — see below; it takes precedence over self-classification. CLP VI: Skin Corr. 1B, Aquatic Chronic 2, STOT SE 3 — H314, H411, H335 Source / form: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32008R1272 [required] Chemical OSH training (substance-specific) (bhp_training) How to comply: Laboratory staff: initial training (general induction + job-specific) + refresher training every 5 years (or every 3 for engineering/technical positions). Documentation kept in personnel files. Source / form: https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20040180169 [required] BDO registration (Polish Waste Database) (bdo_registration) How to comply: The GHS classification of this substance indicates properties that may render the waste arising from it hazardous (Regulation 1357/2014, HP properties — with concentration thresholds calculated from the content in the waste, not in the reagent). Whether this gives rise to an obligation to keep BDO records depends on the waste producer and the scale of activity (Art. 50 of the Polish Waste Act; exemptions include up to 100 kg/year of hazardous waste). This is not a statement of obligation for the purchaser. Source / form: https://bdo.mos.gov.pl/ [to be verified] ADR transport (international agreement) (adr_transport) How to comply: Section 14 of the safety data sheet states UN 1733, but without a confirmed ADR class — verify the transport class in ADR 2025 (Table A) before shipping. Do NOT assume there are no restrictions. Source / form: https://unece.org/transport/dangerous-goods/adr-2025-files [conditional] REACH registration (>1 t/year EU import) (reach_registration) How to comply: Importers/manufacturers ≥1 tonne/year must register the substance with ECHA (technical dossier + Chemical Safety Report if ≥10 t). Check the ECHA Annex VI / registered substances list. Source / form: https://echa.europa.eu/regulations/reach/registration [to be verified] SVHC notification (Substances of Very High Concern) (svhc_declaration) How to comply: SVHC status not verified against the available dataset — check the current ECHA candidate list; do not assume the absence of an entry. Source / form: https://echa.europa.eu/candidate-list-table [to be verified] REACH Annex XIV (authorisation list) (reach_annex_xiv) How to comply: Not verified against the ECHA Authorisation List — check REACH Annex XIV. Source / form: https://echa.europa.eu/authorisation-list [not applicable] REACH Annex XVII (use/marketing restrictions) (reach_annex_xvii) How to comply: Checked against the harmonised classification (CLP Annex VI): the substance has no CMR category 1A/1B classification, so it is NOT subject to the general ban on sale to the general public under entries 28–30 of Annex XVII. NOTE: specific (non-CMR) Annex XVII entries are not covered by the MOL-GOD dataset (incomplete dataset) — if in doubt, check the consolidated Annex XVII on the ECHA website. Source / form: https://echa.europa.eu/substances-restricted-under-reach [to be verified] OEL — Occupational Exposure Limit in the working environment (nds_workplace) How to comply: No NDS data in the MOL-GOD dataset (incomplete set — ~41 of ~600 substances in the list). Absence does NOT mean there is no NDS — check the full list in Dz.U. 2024 poz. 1017 (Regulation of the Ministry of Family and Social Policy of 4 September 2024), and where none exists apply the OEL from EU directives or values recommended by NIOSH/ACGIH.
