Certifications, MOQ negotiation, sample testing and the questions that filter out traders.
The lowest quote you receive is rarely the best deal — it's often a trading company adding a markup on top of a factory price you never see. The checklist below is what experienced buyers actually run through before committing to a supplier, whether it's for a trial order or a full container.
A real manufacturer will readily share its business license, ISO 9001 certificate and BSCI audit report. Cross-check the registered company name against the one on your invoice — a mismatch is the clearest sign you're dealing with a trading intermediary.
Photos can be borrowed from a factory's own marketing materials. A live video call where you can ask the person on the other end to walk to a specific production line, in real time, is far harder to fake.
CE and RoHS cover the EU, FCC covers the US, and UKCA covers the UK post-Brexit. If a supplier only offers CE but you're shipping to the US, that's a compliance gap — ask for the specific test reports for your destination market, not just a general certificate.
A supplier willing to drop MOQ aggressively on the first call, with no sample requirement, is often more interested in closing a deal than protecting a quality standard. A factory confident in its product will usually hold a reasonable MOQ floor while being flexible on mixed-model containers.
Free samples are a red flag as often as they're a good sign — they don't tell you anything about the factory's incentive to prioritize your production run. Paying a small, refundable sample fee (often credited back on the bulk order) is standard practice among serious buyers.
Push for specifics: incoming quality control (IQC) on raw materials, in-process quality control (IPQC) during assembly, an aging or burn-in test, and a final inspection before packing. A defect rate benchmark (ideally under 0.5%) is a good sign the factory tracks its own quality data.
FOB, CIF and DDP shift responsibility (and cost) for freight and customs at different points. Confirm which Incoterm the quote is based on before comparing prices across suppliers — a lower FOB quote can end up costing more than a DDP quote once freight is added.
The buyers who get burned aren't the ones who asked too many questions — they're the ones who assumed a fast, cheap first quote meant they'd found a factory.
A few patterns show up again and again with trading intermediaries: the company can't name which city their "factory" is in without checking; the WeChat or WhatsApp contact is quick to discount aggressively on the first message but slow to answer technical questions about materials or tooling; and the payment details belong to a company name that doesn't match the one on any certificate they've shown you. None of these alone is proof, but two or more together is a strong signal to ask for a live video tour before sending a deposit.
A real manufacturer generally has no hesitation providing: a business license with a registered scope that includes manufacturing (not just trading/import-export); recent third-party test reports with the model number matching what you're ordering; photos or video of your specific product on their own production line, not stock photography; and a factory address you can independently verify appears in customs or trade-directory records under the same company name.
Ask for a live video call where someone walks to a specific production line in real time — photos can be borrowed from marketing materials, but a live walk-through in real time is very hard to fake.
Not always, but a supplier willing to drop price aggressively with no sample requirement and no pushback on MOQ is often more focused on closing the deal than protecting a quality standard.
Paying a small, often-refundable sample fee is standard among serious buyers — free samples don't tell you anything about how the factory will prioritize your actual production run.
