Principle: no data = no claim (we do NOT declare "no restrictions" without a basis). 4 required / 12 items [required] 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). 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 [not applicable] BDO registration (Polish Waste Database) (bdo_registration) How to comply: The verified GHS classification does not indicate classes resulting in hazardous waste — BDO registration for this substance is not required. Verify the EWC code for the specific waste form. Source / form: https://bdo.mos.gov.pl/ [to be verified] ADR transport (international agreement) (adr_transport) How to comply: No ADR data in the MOL-GOD dataset for this CAS number. Do NOT assume there are no restrictions — before shipping, verify the transport classification in ADR 2025 (Table A) and in section 14 of the safety data sheet (SDS). 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 [to be verified] REACH Annex XVII (use/marketing restrictions) (reach_annex_xvii) How to comply: No entry in the harmonised classification dataset (CLP Annex VI) for this CAS number — status of entries 28–30 (CMR ban) NOT VERIFIED; do not assume the restriction does not apply. The dataset of Annex XVII restrictions is also incomplete — check the consolidated Annex XVII and the harmonised CMR classification 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. Source / form: https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20240001017 [to be verified] GIS register (precursors / psychotropics) (gis_register) How to comply: Does not appear in the available working set of precursors (list incomplete). Absence is NOT a confirmation — verify against Annex I of Reg. (EC) 273/2004 and the GIS list before placing on the market.
