How to compare supplier quotes from China (so the cheapest isn't a trap)

A good comparison starts before the quotes arrive. If each supplier gets a different brief, the prices can't be compared. Make the specification, quantity, packaging, delivery term, quality requirement and timeline the same for everyone, then compare the total value and the risk.

In short

• Send the same structured RFQ to every supplier on your shortlist.
• Normalize the commercial terms before comparing unit prices.
• Use a weighted matrix and write down why the winner won.

Build a comparable RFQ

Include enough for suppliers to price the same job:

• Product description, drawings, materials, dimensions, tolerances, colors and functional requirements.
• Target quantity, sample quantity, forecast range and expected reorder pattern.
• Packaging, labeling, carton, pallet and inspection requirements.
• Sample date, production window, shipping destination and delivery term.
• Tooling, mold, setup, artwork, testing, certification and payment assumptions.

Identify the product and the revision being priced, ask suppliers to list deviations in a common response sheet and to separate confirmed answers from estimates. If a material is still open, ask for separately priced options instead of letting each supplier choose an unrecorded substitute, and ask for tooling and sampling costs apart from the recurring unit price. Share any material clarification with every invited supplier: a change that reaches only one makes prices incomparable. Keep the request, clarifications and responses together.

Normalize before you rank

Field	Question
Price	Is the unit price based on the same spec, quantity, currency and packaging?
MOQ	What is the minimum, the price breaks and the pilot-order condition?
Lead time	Does it start after deposit, sample approval, artwork approval or another milestone?
Delivery term	Where does the supplier's responsibility end, and what stays with you?
Quality	Which inspection method, defect tolerance, rework and release rule are assumed?
Risk	How are spec changes, delays, shortages and failed inspections handled?

Put it all in one sheet and keep each supplier's assumptions visible instead of rewriting them into a cleaner but less accurate summary. Use one currency and note the conversion date. Mark an unknown cost as unknown, not zero, or an incomplete quote will look cheaper.

An invented example for 1,000 units: Supplier A quotes 5.00 but excludes packaging, estimated at 0.40 a unit. Supplier B quotes 5.25 with the packaging included. Normalized, A costs 5,400 and B costs 5,250. That doesn't automatically make B the right supplier: check both meet the material, quality, capacity and timing requirements. A price adjustment makes costs comparable, but it can't turn an unverified promise into proof of capability. (Illustrative numbers, not market prices.)

Mandatory requirements first, weights second

Some things a candidate must meet before any scoring: the agreed spec, required documentation, an achievable production plan. Resolve a failure there before debating whether a lower price compensates for it.

Then use a weighted matrix. Price shouldn't automatically carry the highest weight: a brand with a strict delivery promise may weight quality and lead time more, while a wholesaler may weight landed cost, MOQ and replenishment reliability.

• Set criteria and weights before you see the scores.
• Score evidence, not sales language.
• Treat missing information as a risk, never as a silent high score.
• Ask the preferred supplier to confirm the final commercial version in writing.

Test whether a small change in an uncertain score flips the winner. If it does, the decision rests on weak evidence, so get a sample, a reference or a production review first. For Spain and Japan, include destination packaging, documents and delivery needs if they materially affect the order.

Turn the winning quote into a controlled order

Record why it fits your objective and which assumptions still need confirming. Carry the final spec, packaging, quantity, delivery scope, sample approval and inspection requirements into the purchase documents, and get acknowledgement of changes made during negotiation. Archive the unsuccessful proposals (respecting confidentiality). On a repeat order, compare it with the baseline and list what changed, to tell a real price rise from a different quantity, material or delivery term.

FAQ

Should the lowest quote win?

Not automatically. Compare normalized total cost, quality evidence, lead time, MOQ, communication, delivery responsibility and risk.

How many suppliers should I invite?

Enough qualified ones for a meaningful comparison, while keeping the brief and evaluation manageable. Fit matters more than a long unqualified list.

What happens after I choose?

Freeze the final spec, price, quantity, packaging, lead time, quality criteria, payment milestones, delivery term and change process in writing.
