Your induction cooker line will live or die by the factory behind it. Pick right, and you get consistent quality, honest lead times, and a partner that quietly handles private label, certifications, and packaging. Pick wrong, and you get delayed containers, certificates that do not match the shipped product, and a sourcing relationship that eats your margin in hidden rework.
This checklist is written for importers, distributors, and brands evaluating induction cooker manufacturers in China — and it is exactly the list we would want a buyer to run against any factory, including our own.
1. Verify certifications — by model, not by brand
A factory claiming "CE certified" means nothing until you see which models are covered. EU market access for induction cookers rests on three documents: RoHS (2011/65/EU), EMC (2014/30/EU), and LVD (2014/35/EU, tested to EN 60335-2-9). UK-bound products also need UKCA.
Ask for the certificate numbers and the covered model list, then check the holder name on the certificate — it should be the factory you are negotiating with, not a trading company. For reference, our WQ-80 series (8 models) carries the full EU CE suite plus UKCA and ErP standby power testing, and we share certificate copies on request.
2. Check what is actually made in-house
Many "manufacturers" are assembly shops buying PCBA, coils, and panels from third parties. That works — until a component change ripples into your quality.
The strongest signal is in-house production of core components: printed circuit board assembly (PCBA) and heating coil plates. In-house PCBA means the factory controls the most failure-prone part of an induction cooker, and it shows up in more stable lead times and fewer surprises at inspection. Ask directly: "Do you make your own PCBA and coils? Can we see the SMT line during a factory audit?" If the answer is vague, keep looking.
3. Understand the three OEM tiers before you negotiate
OEM is not one service. It is a ladder, and knowing which rung you need saves months of back-and-forth:
- Tier 01 · Brand Label — your logo, color box, manual, and packaging on the factory's proven models. Best for validating a category with your first private-label container. Our MOQ for brand label is 500 pcs per model.
- Tier 02 · Custom OEM — market-specific voltage and plug (220-240V / 110V, EU, UK, US, AU), control panel language, housing color, accessory kit, packaging structure. Best for distributors with fixed market specifications.
- Tier 03 · Full ODM — your product, from brief to container: industrial design, tooling, electronics, firmware, certification support. Quoted per project; SKD/CKD export service available.
A factory that can articulate these tiers (and their MOQ for each) is a factory that has done this before. See the full breakdown on our About page.
4. Ask the four questions that separate factories from traders
- MOQ — and whether it applies per model. (Ours: 500 pcs per model, always.)
- Lead time — from when? Deposit received or order confirmed? (Ours: 35–45 days after deposit received.)
- Samples — are they available before bulk? What is the sample charge policy?
- Payment and warranty — terms per order (T/T is common), warranty and after-sales per the sales contract.
If a supplier answers "it depends" to all four without any reference point, you are not talking to a factory with standard processes.
5. Test response time before you commit
In B2B sourcing, response speed is a proxy for production discipline. Send a realistic inquiry (model, quantity, target market, voltage) and measure how long a real engineer takes to reply — not a sales bot, a real person who can discuss specifications.
We run a 12-working-hour reply commitment on every inquiry, Monday to Saturday. If we cannot meet your requirement, we say so honestly rather than quoting into the void. That commitment is cheap for us to make and expensive for a bad factory to fake.
6. Look for brand proof — then verify it
Long-term OEM partnerships with major brands (Joyoung, Haier, Xiaomi, Royalstar, Airmate in our case) are the strongest third-party validation a factory can show. But verify: ask which models or product categories they build for these brands, and check factory tour photos and audit reports rather than logos alone.
Red flags that should end the conversation
- Certifications listed without model coverage or certificate numbers
- MOQ that changes between email and quotation
- "Unlimited customization" with no engineering team behind it
- Factory photos that are stock images (reverse-image search them)
- A trading company presenting itself as the factory (check the address on the certificate and the business license)
Your next step
Shortlist two or three factories, run this checklist, order samples, and compare. A good factory relationship compounds — every container gets easier, every new product iteration gets faster.
If you would like to test us against this checklist, send your inquiry with your target market and quantity: we reply within 12 working hours, and we will send our catalog and certificate copies for the models you are considering.
