1. Legal and commercial identity
- Legal entity, jurisdiction and registration number.
- Registered address and contracting bank-account identity.
- Quotation validity, Incoterm and named place or port.
- Warranty issuer and claims contact.
A catalogue shows what a supplier wants to sell. Due diligence establishes who will contract, what will actually be supplied, which evidence applies and how non-conforming goods are controlled.
Why the registration record shows two names: KAISTEEL LIMITED (BRN 78595271) was registered in Hong Kong in August 2025 under an unrelated name that never traded and never opened a bank account. It was renamed to KAISTEEL LIMITED in August 2026 specifically to launch this brand for international trade. Ownership was unchanged throughout — this is an administrative rename, not a change of control, and both names appear on the same registration when verified at the Companies Registry.
2. Product definition
- Revision-controlled drawings and final dimensions.
- Approved BOM, finishes and appliance models.
- Electrical, gas, water and drainage interfaces.
- Clear exclusions and local-installation responsibilities.
3. Evidence matching
- Material evidence linked to the selected grade and batch — see what material documents to request.
- Tests matched to the actual substrate and coating system.
- Certificates matched to exact model, ratings and market — see verifying an appliance certificate.
- No component certificate presented as whole-system certification.
4. Quality and shipment
- Defined inspection points and acceptance criteria.
- HOLD, corrective action and reinspection rules.
- Packing BOM, protection method and loading plan.
- Order-specific document index before release.
KAISTEEL control: required evidence is defined at Technical Freeze, collected during production and indexed in the order-specific Compliance Dossier before shipment release.
