- Requirement — share the component, quantity, application, and available files.
- Clarification — identify missing interfaces, conditions, and responsibility boundaries.
- Configuration or drawing review — align the quotation scope to controlled inputs.
- Supplier coordination — review relevant candidate routes without representing them as qualified until evidence exists.
- Quotation — state assumptions, exclusions, documentation, and commercial scope.
- Sample and approval — confirm the agreed validation path where required.
- Production — proceed only against approved requirements.
- Inspection and documentation — provide the agreed evidence, not an implied universal package.
- Shipment and repeat supply — maintain revision and change-control clarity.
What the first enquiry should contain
Identify the component or assembly, the equipment or loop boundary, drawings or reference parts, coolant and operating conditions, quantity, target stage and required documentation. Missing inputs are clarified before an exact configuration is represented.
Decision and approval points
A proposal records assumptions and exclusions. Samples, tests, substitutions and design changes require the buyer-defined approval path; a quotation alone is not a claim of qualification or guaranteed system performance.
