How to write a clear sourcing RFQ

An effective request for quotation identifies the item, quantity, standards, destination and timeline. Include approved alternatives and packaging requirements where relevant. Confirm how suppliers will handle drawings before sharing sensitive files.

Understanding MOQ and lead time

Minimum order quantity is the smallest quantity a supplier will typically accept. Lead time may mean production only, not delivery. Ask separately about production, inspection, pickup, transit and customs clearance.

Construction materials: what to specify

Material grade, relevant standards, dimensions, finish, required volume, delivery address and handling requirements can change a quotation significantly. For aggregates and concrete, local supply and transport are especially important.

Import costs beyond the unit price

A unit price alone does not equal landed cost. Compare Incoterms, origin, tariff classification, freight, insurance, duties, brokerage and taxes. Confirm applicable HS classification with a qualified broker.

Electronic components: avoid specification gaps

Check manufacturer part numbers, revision, packaging, RoHS/REACH or other required certifications, and whether substitutions are permitted. Verify traceability and supplier authenticity.
