Before ordering a material sample, confirm the material specifications, testing requirements, evaluation method, and any payment or minimum-quantity purchase-order condition. Put the technical requirements into a formal quote, and ask the supplier to state any commercial terms that the quote does not cover.
What should the formal quote resolve?
The American Society for Quality recommends providing potential suppliers with specifications and other requirements, including testing, when requesting a formal quote.
Before requesting a sample, make sure the quote request identifies:
- The material specifications relevant to your project
- Any testing requirements
- The intended use of the sample
- Information the supplier still needs before it can confirm feasibility
Check the supplier’s response against each item. If a specification or requirement is disputed, omitted, or qualified, treat it as unresolved rather than assuming it has been agreed.
How will the sample be evaluated?
ASQ identifies prototyping, laboratory testing, and validation testing as ways to evaluate supplier samples. Choose the evaluation route according to the question the sample needs to answer:
- Prototyping: Does the material need to be formed, assembled, or otherwise worked before its suitability can be assessed?
- Laboratory testing: Which defined requirements need measured evidence?
- Validation testing: Does the material need to be assessed against the conditions of its intended application?
Receiving or handling a sample does not, by itself, complete any of these evaluations. Be clear about the evidence you need and whether the supplier or another party is expected to perform the work.
Are payment or a minimum order required?
The U.S. International Trade Administration says a supplier may require payment or a purchase order for a minimum quantity before providing a sample. These are possibilities rather than universal requirements.
Before authorising the request, ask the supplier to confirm:
- Whether payment is required before the sample is provided
- Whether a purchase order is required
- If so, the minimum quantity and whether it differs from the sample quantity
- How any sample charge relates to the purchase order
- Whether a charge is refundable or credited against a later order
- When payment is due and when the sample can be dispatched
The cited guidance does not establish a standard sample fee, refund policy, or delivery timetable. Obtain those terms directly in writing rather than inferring them from the request or from the supplier’s general terms.
Final check before confirming the order
You should have clear answers to four questions:
- Are the material specifications documented?
- Are the required testing or evaluation activities defined?
- Is the sample’s purpose distinct from the evidence needed to approve it for use?
- Have payment, minimum-quantity, fee, refund, and timing conditions been stated where relevant?
If any term you intend to rely on remains unstated, resolve it with the supplier before confirming the order. Silence about a fee, deadline, test, or condition should not be interpreted as confirmation.
