What questions reveal a company's real production capacity?

Ask for monthly output in your own unit, then ask what it depends on: number of lines or machines, shifts run, current utilisation, and the largest single order actually completed in the past year. Ask what proportion of output is exported and to which markets. A capacity figure many times larger than any order the company has actually delivered is a theoretical number. Also ask what they would sub-contract if your order arrived, because the honest answer is rarely nothing.

How do I compare quotations when every company quotes different terms?

Force one structure. Send an identical brief - specification and tolerances, quantity, Incoterm and named port, packing and labelling, lead time, certificates, proposed payment terms - and ask for the reply against that structure. Then normalise everything to a single Incoterm and a single unit before ranking, and add the costs the seller's invoice never shows: destination terminal charges, brokerage, duty and local taxes, inland delivery. Compare response quality alongside price, because it predicts how the order will run.

What are the common signs of a fraudulent or misrepresenting supplier?

Bank details in a different name or country, a late change of banking details, refusal to show premises on a live call, urgency framed as a price rise or a limited allocation, unverifiable registration, and certificate numbers that cannot be checked against the issuer. A price far under the market for the specification you asked for is usually a different specification rather than a bargain. Conversely, a plain website, a small company or imperfect English are not warning signs on their own.

Do I need to visit the factory, or is a remote check enough?

For a first order of modest value, a live video walkthrough at a time you choose, plus independent registry checks, plus a pre-shipment inspection, is usually proportionate. As order value, customisation or regulatory exposure rises, a third-party audit report becomes worth the cost, and above that a visit by you or an agent you appoint pays for itself. The trigger is not the size of one order but the cost of the relationship failing after you have committed to your own customers.

Who is responsible if the goods fail inspection at my end?

Whatever your contract says, which is why the contract has to say it. Fix in the purchase order the specification and test method, the inspection standard and where inspection takes place, the remedy on failure - rework, price adjustment, replacement or cancellation - who pays for inspection and re-inspection, and the time limit for raising a claim. Also record the Incoterm, because it decides where risk in the goods passed from seller to buyer. Without those terms written down, a failure becomes a negotiation rather than a claim.

How many companies should I shortlist, and what should I do first?

Three to five is usually the right number: enough to reveal what the real market price and lead time are, few enough to give each a proper brief. Start by sending all of them the same specification and quantity, then compare how completely and how quickly each replies. Narrow to two, verify those two properly through registry checks and a live call, and run a small first order or a paid pre-production sample before committing volume. The second supplier is worth keeping warm even after you choose the first.

How can I tell whether a company is really a manufacturer or a trader?

Ask directly, then test the answer. Check whether the company's registration lists manufacturing activity, whether process or management-system certificates are held in its own name and for the site it claims, and whether it can show the production step you care about on a live video call at a time you choose. Then ask a technical question that only a maker answers quickly - tolerances, scrap rate, machine capacity, changeover time. Being a trader is not disqualifying, but it changes who can fix a problem and what the price should be.

What documents should I ask for, and how do I verify them?

Ask for the registered legal name, registration or incorporation number, registered address, and export or tax registration number, then check them yourself in the relevant national register instead of accepting scans. Verify certificate numbers against the issuing body's own register, and check the scope and expiry, since certificates are often real but issued for a different site or product line. Confirm that the bank account is in the same legal name and country as the entity on your contract.
