SDS sources & collection methods

Official reference sources

Each reference links to its originating organization. RESDS is an independent document library; these links do not imply endorsement or certification.

Reference field	Source	Scope
CAS RN & chemical identity	CAS Common Chemistry ↗	Look up the CAS record. Not every CAS RN is in the public collection.
Chemical name, formula, molecular weight, synonyms & structure	PubChem · NCBI / NLM / NIH ↗	Compound reference data; individual entries may include contributed information.
Global classification & labelling framework	United Nations · UNECE GHS ↗	GHS Rev.11 (2025). A framework, not a product-specific hazard classification.
European Union · CLP & substance information	ECHA / ECHA CHEM ↗	Check harmonised classifications separately from company notifications.
Australia · industrial chemical inventory	AICIS ↗	Search the inventory by CAS RN. Inventory listing is not a safety approval.

Product composition, grade, hazards, handling and revision dates remain those of the original publisher SDS. Reference properties are displayed only after a single PubChem compound result and an exact CAS synonym match. A matching CAS does not independently certify product composition. Values carry their retrieval date; missing or ambiguous matches remain official lookup links.

About this collection

RESDS is a public reference library for rare earth material documents. The publisher named on each record is the document’s original supplier or issuing organization. RESDS hosts a copy; it does not issue, certify or endorse that SDS.

Original files and searchable text

Original PDFs are retained and identified by a SHA-256 file checksum. A matching checksum identifies the same file; it does not verify the accuracy of its safety statements. Full text is extracted page by page in the original language. OCR is identified where used. Formatting, tables, symbols and recognition errors must be checked against the original PDF.

Dates, materials and versions

The original SDS revision is copied from the document. “Added to RESDS” is the date this copy was published here, and “Record updated” is the date its substantive website content changed. Neither means the supplier revised the SDS on that date. All versions held here remain available; ask the supplier for its latest applicable version.

Material indexes use product-identification metadata. Element associations use the original identification and composition sections, with page references shown on each document. They do not infer composition from incidental words elsewhere in the SDS. CAS-reference indexes may include mixture components. An unclassified record remains searchable. Community uploads and source links are not automatically independently verified.
