BUYER FIELD GUIDE / PRODUCT CONTROL & COMMERCIALISATION
Material Substitution Questions for China Sourcing
Direct answer: A material substitution question is easier to control when the buyer connects the current product version, approved reference, proposed material, supplier source, stated reason, possible effect, and next approval question in one record.
What this guide helps clarify
A supplier may propose an alternative because of availability, cost, process, timing, or another stated reason. The useful response is not to assume the alternative is equivalent or unacceptable. It is to keep the proposed difference visible against the current reference before a buyer decides what needs testing, approval, or a revised record.
Work through the current record in order
- Identify the current approved reference. Record product version, sample, specification, material, finish, package, and current order or development stage.
- Capture the proposed substitute. Keep the supplier message, material description, image, data point, and stated reason attached to the proposal.
- List the decision questions. Record what may need clarification about function, appearance, quality reference, packaging, timing, commercial basis, or testing context.
- Name the next approval record. Keep the buyer decision, revised sample, updated specification, response owner, and next handover visible.
BUYER RECORD / KEEP THESE POINTS CONNECTED
Current product reference, approved material point, proposed substitute, supplier source, stated reason, effect question, buyer approval, and next record.
Questions that make the next record more useful
Approved basis
Which sample, specification, product version, or material reference defines the current point?
Proposed difference
What exactly is the supplier proposing, and what source describes it?
Decision edge
What needs a revised sample, specification, test, buyer approval, or updated production record?
Common ways this record loses clarity
- A substitute is discussed without the approved product or sample reference.
- Cost or timing is mentioned without a visible effect on the product record.
- The supplier proposal is used in production before an approval record is clear.
