Vetting Amazon Suppliers

Screen suppliers for legitimacy and capability before you discuss price.

Why vetting comes before price

A quote is the easiest thing to compare and the least useful thing to compare first. Unit cost tells you nothing about whether a factory actually makes your product, holds the certifications your category requires, or will still answer once your deposit clears.

Vet first, negotiate second. A supplier who fails the screen is not a cheaper option — treating them as one only moves the cost somewhere you cannot see it: a missed production window, a failed inspection, a listing suspended for documentation you were never sent.

Cheap is rarely cheap
A low unit cost from a factory that does not specialize in your product is a price for something they have not made before.

Where to find manufacturers

Most first-time sellers find suppliers through one of three routes, which differ in reach and in how much verification they do for you.

Sourcing marketplaces

Widest reach, least signal — listings are self-reported, so you verify almost everything yourself.

Sourcing agents

Narrower and curated, but you inherit a second party whose incentives and fee structure you must check.

Trade shows

Narrowest reach, highest signal — confirm the booth is the manufacturer, not a trading company.

Start with a marketplace to learn what your product costs and who makes it. Use the other two once you know what you are looking at.

The five screening bars

Apply the same five bars to every supplier, before any of them sends a number. A supplier either clears a bar or does not, which keeps the shortlist honest.

Main product match

This is what they manufacture, not a side line they will subcontract.

Years in business

Enough operating history to have solved problems before yours.

Certifications

The specific ones your category and destination market require.

Communication

Prompt, clear, professional replies you never have to chase.

Capacity to grow

They can scale volume as your order sizes increase.

Which certifications are mandatory depends on your product category and destination market. Determine that list before you contact anyone, so you screen against it rather than accept whatever a supplier volunteers.

A three-step vetting sequence

Run the same sequence every sourcing round. It stays interpretable and keeps price out of the conversation until you have earned the right to have it.

1

Shortlist

Filter candidates against the five bars using their public profile and their first replies. Cut anyone who fails a bar, regardless of their quoted price.

2

Verify

Confirm the claims independently, using the checks below. A supplier who resists verification has told you something.

3

Quote

Send the same request to everyone who survived, on identical terms, so the numbers that come back are comparable.

Only the third step involves price. If you are negotiating with a supplier you have not verified, you have skipped a step.

Verifying what a supplier claims

Everything on a supplier profile is self-reported. Treat each claim as a question rather than a fact, and confirm it before money moves.

Before money moves
  • Ask for their business license and check the registered name against the one on the quote.
  • Request certification documents, then verify them with the issuing body rather than the supplier.
  • Ask what else they manufacture. A real factory answers specifically; a trading company answers broadly.
  • Ask for references from buyers in your destination market, and contact them.
  • Send a technical question only a manufacturer could answer, and read how they handle it.
  • Ask how an order several times your first run would change their process and lead time — a factory with real capacity answers with specifics, not reassurance.

Deposits rarely come back

Once money crosses a border, recovering it is a legal project — verification is the cheap version of that fight.

A supplier who clears all five bars and survives verification has earned a sample order, not a purchase order. That distinction is the subject of the next guide.
