The lowest unit price is not always the lowest project cost. Compare tooling, specifications, sample scope, quality controls, packaging, communication and repeat-order support on the same basis.
1. Check whether the supplier fits the project
Ask which molding processes, materials, part sizes and production volumes the supplier normally handles. Confirm whether tooling, molding, printing, assembly and packaging are completed internally or by approved partners.
Request evidence that matches your risk level: business identity, relevant factory information, sample records, material documents, inspection examples and certificate verification details when a certificate is claimed.
2. Normalize quotations before comparing prices
Two quotations may include very different assumptions. Build a comparison sheet covering material, part weight, cavity count, tooling ownership, sample quantity, unit price breaks, packaging, testing, shipping terms and payment terms.
- Confirm whether tooling and sample revisions are included
- Check whether unit price includes printing, assembly and packaging
- Separate one-time development cost from repeat-order cost
- Record quote validity and assumptions about annual volume
3. Define sample approval and production inspection
Create an approval checklist before samples arrive. It should cover dimensions, material, hardness, color, appearance, function, logo and packaging. Photos are useful, but measurable acceptance criteria reduce disagreements.
For bulk production, agree which checks occur at incoming material, first article, in-process production, final inspection and packing. The inspection level should match product risk and buyer requirements.
4. Treat packaging and logistics as product requirements
Confirm unit packaging, carton quantity, carton marks, barcode or label files, pallet requirements and destination shipping terms before production. Packaging changes late in the process can affect price, schedule and carton dimensions.
5. Send every supplier the same RFQ package
Send one complete RFQ package so the quotation can reflect the same product scope.
Frequently asked questions
What should a silicone product quotation include?
At minimum, confirm product specification, tooling scope, sample plan, unit-price quantity breaks, customization, packaging, payment terms and shipping terms.
How can buyers verify a claimed certificate?
Request the certificate, scope, legal company name, issuing body and reference number, then verify it with the issuer or its official database when available.
What is the best way to compare two suppliers?
Use the same RFQ package and compare total program assumptions, not only unit price. Differences in tooling, material, inspection and packaging can change the real cost.
