Principle: no data = no claim (we do NOT declare "no restrictions" without a basis). 8 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). For this substance a HARMONISED CLASSIFICATION applies (CLP Annex VI) — see below; it takes precedence over self-classification. CLP VI: Flam.

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://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.
