Every year, brands lose product launches, deposits, and marketplace positions because they chose a manufacturer based on price and responsiveness without asking the right questions first. In adult wellness manufacturing, the consequences of a wrong supplier choice are compounded by compliance risk: a CE certificate that fails Amazon EU audit, a silicone material that triggers a customer safety complaint, or a delivery delay that breaks a seasonal campaign.

This guide is a structured interrogation checklist. Use it before requesting a sample, before signing an NDA, and certainly before placing a first bulk order. Each question is specific, the expected answer is defined, and the red flag is explicit.

Question 1: Show Me Your Business License

Why this question matters: A legitimate manufacturing company in China is registered with the State Administration for Market Regulation and has a publicly verifiable business license (营业执照). The license shows the company's legal name, registered address, registered capital, and business scope. A trading company, agent, or unregistered operation cannot produce this document for a manufacturing entity.

Good answer: The factory sends you a photo or scan of the business license immediately, along with instructions for verifying it on China's National Enterprise Credit Information Publicity System at gsxt.gov.cn. The business scope on the license includes manufacturing.

Red flag: The factory says it will "arrange" a business license, suggests verification is complicated, or sends you a document with a different company name than the one you're corresponding with. Any version of "trust us" in response to this question is a disqualification.

Question 2: Are You the Manufacturer or a Trading Company?

Why this question matters: Trading companies source from multiple factories and add a margin. The factory that produces your goods may have different quality standards, capacity, or compliance capabilities than what the trading company represents. A trading company cannot give you direct factory access, direct QC oversight, or direct technical communication with the production team.

Good answer: The supplier explains that they own the production facility, can show you the injection moulding machines, assembly stations, and QC lab on a video call, and are willing to show you the production floor including areas they're not proud of. They can tell you exactly how many production lines they operate and what their monthly capacity is in units.

Red flag: Evasive answers about facility ownership. A pre-produced promotional video rather than a real-time video call. Inability to answer specific technical questions about the production process, such as what motor supplier they use or how their silicone is bonded. If they can't explain the manufacturing process in detail, they're not doing it.

Question 3: Which Certification Bodies Issued Your CE and RoHS Documents?

Why this question matters: CE marking is a manufacturer's self-declaration, but the underlying test reports that support it must come from accredited laboratories. Knowing which lab issued the test report tells you whether the documentation is verifiable and whether it meets the level of evidence that Amazon EU, UK retailers, and EU customs authorities will accept.

Good answer: The manufacturer names the specific lab — SGS, TÜV Rheinland, Bureau Veritas, Intertek, or a CNAS-accredited Chinese lab — and provides the lab's accreditation number. They can send the original test reports (not just a DoC summary) showing the lab's letterhead, accreditation reference, and the actual measured values for each tested substance.

Red flag: "CE certified" without being able to name the testing lab. A DoC with no supporting test reports. A RoHS certificate that was "issued internally" by the factory's own QC department without third-party verification. Any resistance to showing the original lab report rather than a manufacturer-branded summary document.

---

Question 4: Can I Arrange a Third-Party Factory Audit?

Why this question matters: A manufacturer who operates legitimately and meets their stated quality claims has nothing to fear from an independent audit. A factory that objects to third-party audits is protecting something: inflated capacity claims, substandard QC procedures, or undisclosed subcontracting.

Good answer: "Yes. We welcome SGS, QIMA, and Bureau Veritas audits. We can coordinate access to all production areas including the QC lab and raw material storage. Let us know the date and we will have the production team available." Some factories will mention that they have passed previous audits by other buyers.

Red flag: Any version of "our factory doesn't do audits," "audits require a fee from you," or "we're too busy right now." A factory that conditions audit access on placing an order first is not a factory you should place an order with. Legitimate manufacturers understand that third-party verification protects both parties.

---

Question 5: What Is Your Actual Outgoing Defect Rate and How Is It Measured?

Why this question matters: Every manufacturer claims low defect rates. The question is what measurement methodology they use. Statistical sampling (AQL) can report a low defect rate while allowing a significant number of defective units to ship. 100% inspection is the only method that can genuinely support a claim of below 0.1% outgoing defect rate.

Good answer: The factory describes a 100% final inspection process covering specific measurable criteria: IPX waterproof test (specifying the test method and duration), motor function test across all modes, noise measurement (specifying the instrument and distance), charging cycle verification, and surface finish inspection. They should be able to tell you their actual defect rate from last month's production records, not a marketing claim.

Red flag: Claims of very low defect rates without describing the inspection methodology. Inability to explain what specific tests are performed on every unit. A description that relies entirely on "our workers check quality" without mentioning specific test equipment. AQL sampling as the only QC method for an outgoing defect rate claim.

Question 6: What Is Your Silicone Raw Material Grade and Supplier?

Why this question matters: The word "silicone" covers a spectrum from medical-grade to industrial-grade materials. For skin-contact adult wellness products, the appropriate standard is food-grade silicone meeting FDA 21 CFR 177.2600 — the same standard used for food processing equipment and baby products. Industrial silicone or unspecified silicone compounds are not appropriate for adult wellness applications.

Good answer: The manufacturer names the specific silicone supplier — Wacker Chemie (Germany), Shin-Etsu Chemical (Japan), or Momentive (US) are reference-grade suppliers for the industry — and can provide the MSDS identifying the exact silicone grade designation (e.g., Wacker Elastosil). They can provide an SGS or Intertek test report confirming FDA 21 CFR 177.2600 compliance for the specific silicone grade used.

Red flag: "We use body-safe silicone" without naming the supplier or grade. Inability to provide an MSDS. A test report that says "food grade silicone" without identifying the supplier or grade code. Any resistance to naming the raw material supplier on the grounds of "confidentiality" — there is no legitimate confidentiality concern in naming your material supplier to a buyer.

---

Question 7: Do You Subcontract Any Part of My Order?

Why this question matters: Subcontracting breaks the chain of quality control. If a factory subcontracts your packaging to a third-party print shop, your PCB assembly to a component supplier, or your silicone moulding to a neighbouring factory, they have limited visibility and control over those processes. Subcontracting that is not disclosed to the buyer is a significant breach of trust and contract.

Good answer: "We produce all core components in-house. We source standard components (motors, battery cells, standard PCBs) from our approved supplier list. We do not subcontract production of any component that is unique to your product to a third party. Our standard packaging is printed by [named supplier], which you can visit." This answer is specific and honest.

Red flag: A blanket "everything is done in-house" claim that unravels when you ask follow-up questions about specific components. Any version of "we coordinate production" which is trading company language. Inability to tell you where your motors are sourced from or who prints your packaging.

---

Question 8: Who Owns the Mould for My Customized Product?

Why this question matters: If you are commissioning a custom shape, custom logo engraving, or any tooling modification, the mould is a physical asset with significant value (USD 3,000–8,000 for a new mould). If the mould is legally owned by the factory, you cannot transfer production to another factory — you are locked in. Mould ownership must be established contractually before tooling payment is made.

Good answer: "The mould is paid for by the buyer and is buyer property. We will engrave your company name on the mould. You have the right to transfer the mould to another factory on 30 days' written notice. We will store the mould securely and provide mould condition reports on request." This answer, in writing in the purchase order, is the correct standard.

Red flag: Any suggestion that the factory "owns" tooling paid for by the buyer. A factory that cannot commit to transferability in writing. "We keep the mould here for safekeeping" without a written agreement about ownership and transfer rights. Some factories issue separate tooling agreements that restrict mould transfer — read these carefully before signing.

Question 9: What Are Your Payment Terms and What Happens If Production Is Delayed?

Why this question matters: Payment terms define your risk exposure. The industry standard for B2B orders is 30% T/T deposit to start production, 70% T/T balance before shipment after passing pre-shipment inspection. Any deviation from this structure — particularly 50% or 100% upfront — shifts risk entirely to the buyer. The delay clause matters equally: if a factory commits to a lead time in the purchase order, there should be commercial consequences for exceeding it.

Good answer: Standard 30/70 T/T terms with the balance tied to passing pre-shipment inspection (SGS or buyer-arranged inspection). A written lead time commitment in the purchase order. A factory willing to include a delay clause — even a modest one (price credit for delays exceeding 10 business days) — is demonstrating confidence in their production schedule.

Red flag: Requirements for 50% or 100% upfront payment, particularly from a factory you haven't worked with before. Reluctance to put the lead time in writing. No provision for pre-shipment inspection before balance payment. "We've never missed a deadline" is not a contractual commitment.

---

Question 10: How Do You Handle a Pre-Shipment Inspection Requested by the Buyer?

Why this question matters: Pre-shipment inspection by an independent body (SGS, QIMA, Bureau Veritas) is the buyer's single most effective safeguard against receiving non-conforming goods. A factory that objects to independent inspection has something to hide. The inspection costs USD 300–500 and takes one day — this is a trivial cost relative to the order value, and a legitimate factory knows this.

Good answer: "We welcome pre-shipment inspection. We will notify you when production is 95% complete so you can arrange your preferred inspector. We provide full access to all production areas and QC documentation during the inspection. Our standard practice is to arrange shipping after the inspection report is approved." This answer, with no hesitation, is what a legitimate factory says.

Red flag: Any additional fee charged by the factory for "facilitating" third-party inspection — legitimate factories do not charge for this. Insistence on shipping before inspection is complete. "We do our own QC so you don't need external inspection." A factory that discourages pre-shipment inspection is the factory most in need of one.
