Legal Disclosure Controls

Legal Gate

Control	Required Wording
No Public Offer	Material information is indicative registry content and does not constitute a public offer, quotation or shipment authorization.
Specification Confirmation	Purity, particle size, packaging, stock and production capacity are subject to supplier confirmation and batch-specific documentation.
Compliance Review	Price, documents and shipment release require RFQ approval, restricted-party screening, destination screening and end-use review.
Controlled Documentation	CoA, TDS, SDS/MSDS, origin evidence and export documents remain Vault-controlled until the buyer passes validation.
Export Control Notice	Shipment may be refused, delayed or re-routed where export-control, sanctions, end-use or transportation rules require it.
