Product sourcing questions
What should a steel or aluminum RFQ include?
Include the grade or alloy, applicable standard, product form, complete dimensions and tolerances, quantity, surface or coating, end use, destination, Incoterm, required documents and target timing.
How are grades and standards reviewed?
Grades and standards are treated as order-specific references. We review the requested combination against the product form, dimensions, intended use and destination before confirming a supply option.
How are MTCs and inspection requirements confirmed?
State the required MTC, inspection documents and any third-party inspection in the RFQ. Document scope, inspection points and acceptance requirements are confirmed before quotation or order.
How are packing, marking and shipment requirements handled?
Packing, marking and shipment arrangements depend on the product, dimensions, destination and transport method. Include any project-specific or destination-specific requirements in the RFQ.
Why are price, MOQ and lead time confirmed per RFQ?
Price, minimum order quantity and lead time depend on the specification, quantity, suitable supply option and market timing, so they are reviewed for each RFQ rather than stated as universal terms.
