Buyer context
Ask the supplier to separate one-time preparation costs from repeat unit pricing. If tooling is involved, agree ownership, maintenance responsibility and the procedure for a future design change. These commercial points are easier to settle before samples are approved.
Putting it into the enquiry
Do not infer operating limits from colour or a generic polymer description. Product-level requirements and acceptance evidence should govern the decision. Record approved material and component revisions so that later purchasing remains consistent.
What to confirm
- Tooling and sample cost separation
- Component and closure scope
- Revision control for repeat orders
Can the same moulded shape use different materials?
Potentially, but a material change requires review against the approved packaging requirements; visual similarity is not evidence of equivalent performance.
