A document pack is useful only when it can be connected to the material being purchased. Keep the quoted product, manufacturer, specification and document revision aligned. A certificate covering a different product or scope may not answer the project’s requirement.

Check scope before appearance
Look beyond a logo or cover page. Check whether the document identifies the actual offered product and the requirement it is meant to support. Ask for clarification when names, model references or standards do not align.
Resolve substitutions explicitly
If a supplier proposes an alternative, record the original requirement, the offered alternative and the reason for the change. Route the comparison to the project reviewer. Keep the accepted deviation with the purchase documents so later deliveries can be checked against the same basis.
Connect approval with delivery records
Agree which labels, packing lists and traceability records are required. Identify any inspection or release points before shipment. Keep material-supply responsibilities separate from installation and commissioning responsibilities.
Protect confidential project information
Share only the drawings and schedules needed for quotation, using the project team’s agreed process. Remove unrelated private details from examples intended for public use. Do not publish customer names, project claims or certificates without the relevant permission.
Send a clear document request
Tell HZX which documents your project requires when you submit the BOQ. Availability and scope can then be reviewed for the proposed product rather than assumed for an entire product family.
Discuss your material schedule
Browse MEP product references or Request a Quote. Include the application, quantities, destination and required documents. Drawings and schedules can be sent to hzx@hzxtech.com.
Copy-and-fill enquiry template
Copy the template below into your email or enquiry. Replace each bracketed prompt with your details; brackets are placeholders, not product specifications. BOQ means Bill of Quantities (your material list), and RFQ means Request for Quotation. Write “To be confirmed” for anything you do not know yet. Send drawings or files separately by email if available.
BOQ line and offered product: [reference] Manufacturer and model: [details] Required document: [datasheet / report / certificate / drawing] Required scope and revision: [requirement] Received document reference: [reference] Outstanding discrepancy: [question] Project approval status: [pending / accepted / revise]
