Induction vs Infrared Cooker: What Importers Should Compare

Induction, infrared or ceramic hob? A B2B buyer's comparison across heating tech, cookware compatibility, market demand and aftermarket.

Most first-time factory visits are won by "18,000 square metres, 300 workers, 40 countries". All true, and all useless for answering the only question that matters: can this factory ship a compliant product on time? Here are seven checks you can run without getting on a plane.

1. Business licence and scope

Ask for: the business licence scan, with the scope of business readable.

Passes if: the scope includes manufacturing of household appliances, and the company name matches the bank account name.

Fails if: the scope says trading or sales only (that is a trader), or the company name differs from the receiving account.

Also check the registration year. A two-year-old factory is not disqualified, but it needs more scrutiny.

2. A one-take factory video, shot to your script

Ask for: three segments, filmed on a phone, no editing, no music:

Segment 1: from the factory gate sign, walk to the workshop in one continuous shot
Segment 2: hold on the PCB line for 20 seconds — the point is whether an SMT machine is visible
Segment 3: walk to the warehouse, film one shelf, read out the model number on a carton

Why this script: one continuous shot defeats splicing; the SMT machine tells you whether "we make our own PCB" is true; reading a carton proves stock exists.

Fails if: "the workshop is being renovated" or "video needs approval" — that is usually a trader.

3. The first ten BOM lines

Ask for: brand and part number of the heating plate, IGBT, main control chip, panel glass and fan.

Passes if: specific part numbers, and they are real purchasable parts.

Fails if: "we use good quality" or "imported".

The IGBT and heating plate determine lifetime and cost. A supplier who can name them is actually building the product.

4. The certificate model must match your order

Ask for: the DoC and test report for your target model.

Passes if: the model string matches the quotation character by character.

Fails if: "the same series is covered".

This is checked at EU customs and in channel audits. A mismatch means batch rejection.

5. Line takt time

Ask: how many units does this line output per day, with how many operators?

Calculate: daily output ÷ operators ÷ 8 hours = seconds of labour per unit.

Passes if: the numbers are consistent when asked twice.

Then ask: if I place 1,000 pcs now, what date does production start? What you are testing is whether they will commit to a date, not whether the capacity sounds large.

6. Export record you can verify

Ask for: the list of destination countries over the last year, plus the duration of any one customer relationship (customer name can be redacted).

Passes if: the country list matches the certification regimes you need.

You can also check independently: some customs data platforms expose shipper records (for example ImportYeti for US imports). A company with bill-of-lading records is more credible than one that only talks.

7. Buy a sample with your own money

Do not ask for a free sample. Pay for one or two units.

Check:

  • Is there a manual, and is it multilingual?
  • Is the rating plate correct, with the right model and certification marks?
  • Button feel, noise, heating uniformity
  • Is there a certificate of conformity or warranty card in the box?

Fails if: an engineering sample arrives loose in a plain carton.

The one-line summary

"18,000 m² and 300 workers" is a self-introduction. "BOM part numbers + a certificate that matches the model + a one-take workshop video" is evidence. The first is free to say; the second costs something to produce.
