A supplier audit should verify the capabilities behind product samples. Buyers need to understand how the factory controls knitting, sizing, materials, testing, inspection and records across repeat orders.
The best questions ask for evidence rather than yes-or-no answers. Request examples, process records and a walk-through of how a plus size order moves from brief to shipment.
What buyers should define before sampling
A complete brief gives the factory a measurable target and reduces revisions. Confirm these points before treating a sample as ready for approval:
- Which machines and constructions support the target calf ranges?
- How are ankle, calf, foot and length measurements graded?
- How is compression performance verified?
- How are yarn lots, colors and production batches traced?
- What in-process and final inspections are recorded?
- How are approved samples and specification revisions controlled?
Questions about product development
Ask how the factory creates a new wide calf pattern, how many sample rounds are typical and which measurements are used to approve the range. Request an example of a size specification without confidential customer details.
Also ask how patterns, zippers, open toes or special cuffs change machine setup and lead time.
Questions about quality and testing
Review how measuring tools are calibrated, how samples are selected and how defects are classified. Ask what happens when in-process measurements move outside tolerance.
For compression specifications or regulated channels, examine available testing arrangements and how reports are linked to the produced style.
Questions about capacity and communication
Confirm normal and peak capacity, production planning, subcontracting policy and how delays are reported. A factory may have strong samples but limited ability to reproduce them during a busy season.
Ask who owns the project, who approves technical changes and how English artwork or shipping documents are checked.
Sample approval checklist
Use the approved sample as a production reference, not only a sales photo. Record the results of the following checks and retain the final version:
- Request records that support verbal answers.
- Trace one sample from yarn to final packaging.
- Check that measuring methods are documented.
- Review storage of approved samples.
- Ask how nonconforming goods are isolated.
- Confirm who can authorize a specification change.
OEM and commercial planning
The remaining audit questions should cover MOQ structure, material sourcing, packaging partners, social or compliance requirements, export experience, complaint handling, repeat-order consistency, lead-time control and confidentiality. Score suppliers against the same criteria instead of choosing only by sample price.

Common mistakes to avoid
- Accepting a showroom tour as a complete audit.
- Asking broad questions without requesting evidence.
- Ignoring subcontracted processes.
- Focusing on capacity without checking measurement control.
- Failing to document follow-up actions.
Final recommendation
Use the audit to understand how the supplier manages variation. A reliable wide calf program depends on controlled sizing and repeatability as much as attractive samples.
Specifications and claims should be confirmed for the product, sales channel and destination market before ordering or publishing customer-facing materials.
FAQ
Is a remote audit useful?
It can provide valuable process evidence through live video, records and sample review, although some buyers may still require an onsite or third-party audit.
What evidence should buyers request?
Examples include specifications, inspection records, calibration records, traceability documents, test reports and approved-sample controls.
Should subcontractors be discussed?
Yes. Buyers should understand which processes are external and how the supplier controls them.
How should suppliers be compared?
Use a consistent scorecard covering capability, quality, communication, capacity, compliance, cost and commercial fit.
