China manufactures approximately 70% of the world's adult wellness products. The factories in Guangdong province — primarily in Dongguan, Shenzhen, and Guangzhou — produce everything from entry-level catalog items to premium OEM products for major global brands. For B2B buyers, the sourcing infrastructure is mature, the supply base is deep, and unit economics are compelling at almost any volume above 300 units.

The challenge is not finding suppliers. The challenge is distinguishing verified manufacturers from trading companies, evaluating quality before bulk commitment, and structuring the order in a way that protects you legally and commercially. This checklist gives you a step-by-step process for doing exactly that — whether this is your first import or your tenth.

Step 1: Define Your Product Requirements

Every sourcing error that compounds into a costly problem — wrong certifications, unacceptable quality, customs delays — traces back to an insufficiently defined brief. Before contacting a single supplier, document the following:

Product Specification

• Product type: vibrator, wand, couples device, pump, ring — the category determines which factories to approach and which certifications are required.
• Material specification: medical-grade / FDA-grade silicone for all external surfaces; ABS for internal structure. Do not accept proposals that use ABS externally.
• Waterproof rating: IPX5 (shower-safe) or IPX7 (submersible). Specify this in writing — it directly affects the sealing design and adds USD 0.80–1.40 to unit cost for IPX7.
• Motor type: single or dual; ERM, coreless DC (N20), or LRA. This defines the vibration character and noise level.
• Charging type: magnetic pin, USB-C, or micro-USB. Magnetic pin is the current premium standard for waterproof devices.
• Battery capacity: 500–1,200 mAh is standard. Larger cells extend runtime and add marginal cost.

Business Parameters

• Target quantity: your first order MOQ, and your projected 12-month volume. Both matter — factories quote better unit prices for buyers who communicate scale credibly.
• Target market: EU, US, UK, or global. This determines which certifications you need (CE for EU, FCC for US BLE products, UKCA for UK).
• Sourcing model: catalog private label (your logo on an existing product), custom colour and packaging, or full custom OEM with a new mould. Each has different MOQ and lead time implications.
• Budget range: EXW unit cost target. This anchors your supplier conversations and helps eliminate factories whose cost structure is incompatible with your retail price point.

Step 2: Research and Shortlist Suppliers

There are four primary channels for finding adult wellness manufacturers in China. Each has different verification depth and supplier quality distribution.

Alibaba and Made-in-China

Alibaba is the largest B2B platform for Chinese suppliers but has a significant proportion of trading companies presenting as manufacturers. Made-in-China and Global Sources have slightly higher factory ratios. On any platform, apply these initial filters before contacting anyone:

• Verified supplier badge (Alibaba Gold Supplier or equivalent platform verification)
• 3+ years on the platform
• Existing CE and RoHS documentation shown in the company profile
• Response rate above 80% — low response rate indicates either high volume trading activity or poor account management
• Product photos that show actual factory production, not stock photography

Canton Fair

The China Import and Export Fair (Canton Fair), held twice yearly in Guangzhou, is the most reliable in-person screening environment. Phase 1 (electronics and consumer products) includes adult wellness manufacturers. Visiting allows you to inspect actual products, meet factory sales teams, and collect business cards that link to verifiable factory entities. Factories with Canton Fair booths have passed a level of screening that pure online listings do not require.

Industry Referrals

The most reliable supplier introductions come from other buyers in non-competing markets. If you are sourcing for the US market, a buyer sourcing for the Australian market may share a verified factory contact. Professional sourcing agents with category specialisation can also shortlist manufacturers based on prior audit experience.

Shortlisting Criteria

After initial outreach, shortlist to 3–5 suppliers who have confirmed all of the following in writing:

• Business license available for review (not blurred or withheld)
• CE Declaration of Conformity for the product model you are interested in
• RoHS compliance certificate
• Silicone MSDS identifying the material grade
• Willingness to provide a live video factory tour
• Explicit confirmation they manufacture — not source and resell

---

Step 3: Verify Certifications and Compliance

Certification fraud is common in the adult wellness category. The most frequent pattern is using another product's or another company's certification documents, with the product model number changed. A systematic verification process catches this in minutes.

---

Step 4: Request Samples and Test Quality

No serious B2B buyer should commit to bulk without a physical sample. Samples serve two purposes: confirming that the factory can produce to the specified standard, and giving you a test unit against which bulk delivery is evaluated. A factory that resists sampling is either not capable of meeting your specification or not interested in qualifying buyers — either way, move on.

Sample Request Protocol

1. Request the exact configuration you intend to bulk order: colour, material, packaging, firmware. A sample in a different colour is acceptable for material evaluation but not for colour matching.
2. Pay for the sample. Reputable manufacturers charge USD 30–100 for a sample unit plus shipping. A factory offering free samples to first-time enquirers is typically a trading company recovering cost from bulk margins.
3. Request a signed sample approval form confirming the sample represents the production standard.

Step 5: Negotiate MOQ, Price and Terms

Price negotiation for adult wellness OEM follows the same logic as any manufactured goods category: MOQ, payment terms, and specification complexity are the three levers that move price. Understanding each lever allows you to negotiate effectively without simply asking for a discount.

MOQ and Unit Price Relationship

For a mid-range silicone vibrator manufactured in Dongguan (EXW pricing, 2025):

Payment Terms

Standard payment terms are 30% deposit by T/T (SWIFT bank transfer) to start production, and 70% balance by T/T before shipment — after passing pre-shipment inspection. Do not agree to 50/50 terms on a first order; this reduces your leverage if quality issues emerge. Do not pay by PayPal for bulk orders — the 3–5% surcharge is effectively a hidden price increase, and PayPal dispute resolution is not designed for manufactured goods transactions.

What to Include in the Purchase Order

• Exact product specification (material, motor model number, colour Pantone reference, waterproof rating)
• Packaging specification (box dimensions, print specification, FNSKU if Amazon FBA)
• Defect rate tolerance (AQL 2.5 is standard; specify in writing)
• Lead time in calendar days from deposit receipt
• Pre-shipment inspection requirement (SGS, QIMA, or buyer's agent)
• Documentation package required with shipment

---

Step 6: Place Order and Confirm Details

Before transferring the deposit, confirm the following in writing from the factory — ideally via email so there is a documented record:

1. Production timeline: start date and expected shipment date in absolute calendar terms, not business days from an undefined start point.
2. Counter-sample approval: for custom colour or packaging, request a pre-production counter-sample before mass production begins. This adds 5–7 days to the timeline and saves significant rework cost if colour or packaging does not match.
3. Export documentation package: confirm which documents are included — commercial invoice, packing list, certificate of origin (Form A or CO for preferential tariff treatment), CE DoC, RoHS certificate, MSDS, and test reports.
4. NDA: if you are sharing custom design files, artwork, or a proprietary mould, sign an NDA and ensure the design files are in your possession — not only on the factory's server.

Step 7: Pre-Shipment Quality Inspection

Pre-shipment inspection (PSI) is the single most effective risk mitigation tool available to import buyers. A third-party inspector visits the factory when production is 80–100% complete and inspects a statistical sample of units against your purchase order specification. Problems found at this stage can be corrected before shipment at the factory's cost. Problems found after shipment require dispute resolution, return freight, and potential customs complications.

Recommended inspection providers: SGS, QIMA (formerly AsiaInspection), Bureau Veritas, Intertek, and V-Trust. Cost is typically USD 200–350 per inspection day, which covers up to 300–500 units depending on product complexity. For orders above 1,000 units, a two-day inspection is advisable.

Step 8: Packaging and Shipping

Once the shipment passes pre-shipment inspection, confirm the following before releasing the balance payment and authorising shipment:

Incoterms Selection

For first-time importers, EXW (Ex Works) or FOB (Free on Board) are the most common terms. EXW means you arrange collection from the factory gate; FOB means the factory is responsible for delivery to the port and loading. FOB is typically preferable — it reduces local logistics complexity and the factory's established freight relationships often secure better port handling rates.

For experienced importers with an established freight forwarder relationship, EXW gives you full control over the entire logistics chain. Avoid DDP (Delivered Duty Paid) on first orders with new factories — DDP pricing obscures the true logistics cost and customs value declaration, which can create compliance issues.

Shipping Method

Step 9: After-Sales Support

Your relationship with a manufacturer does not end at shipment. Establish the following expectations in writing before placing the first order — they are far easier to negotiate before the order than after a problem occurs:

• Defect warranty period: 12 months from shipment is standard for reputable manufacturers. Request replacement units (not refunds) for defects within this period.
• Replacement rate: standard is 1–2% replacement stock included in the production run for anticipated handling defects. Request this in writing.
• Firmware updates: for Bluetooth-enabled devices, confirm whether firmware is updateable and who controls the update release process.
• Repeat order pricing: agree in principle that repeat orders at the same specification receive the same or better unit pricing — prevents price creep on established products.
• Documentation updates: confirm the factory will provide updated certificates if yours expire before the next order cycle.
