How to test a supplier's capacity claim without inventing a number

“High capacity” is not a measurable field. Even a stated monthly unit count can hide bottlenecks, product mix and existing commitments.

What the primary source can establish

The U.S. International Trade Administration due diligence guide is the first-party reference for this guide. The guide separates country, company or partner, and purchasing risks and calls for continuing due diligence. It does not investigate or endorse any named supplier on Source Ledger. The steps below are our editorial method for making a buyer-facing field more precise.

A field-level check

Ask for the unit, product configuration, period, shift assumptions and lead-time basis. Request a dated production plan or other material that explains the number. Treat it as a supplier statement unless a relevant check has been recorded.

Write down the exact field, the party that supplied the information, the original document or page, the date seen and the scope of the check. If a reviewer took an action, record that action rather than a general “verified” label. Reopen the source when the transaction or underlying document changes.

Where the inference stops

Do not extrapolate a plant-wide maximum from one machine or from a past shipment. A capacity claim for standard goods may not apply to customised goods or the buyer's required date.

A missing answer is a question to resolve, not permission to substitute a guess. Separate a statement by the supplier from a public record and from a documented human review. No source in this article proves a quality ranking or an existing buyer relationship.

What to record before deciding

Show the exact assumptions beside any capacity figure and mark the evidence level. If the basis is unavailable, omit the figure and ask for a commitment in the quotation.

This entry describes how to evaluate evidence. It is not a dossier for a real company, an approval decision or a substitute for transaction-specific professional review.

Common question

Can a marketing statement of “10,000 per month” be listed as verified capacity?

No. It may be quoted as the company's claim, with assumptions and date, until checked against appropriate operational evidence.
