Sourcing products from China: what to know
Reviewed guide · updated 15 Sept 2026Sourcing products from China: what to know. This short guide is for buyers of consumer accessories, plastic components, optical goods and small soft goods listed on SupplySpark. It summarises where suppliers cluster, realistic MOQ and certification profiles drawn from the SupplySpark Manufacturers in China dataset, plus practical expectations on cost drivers, negotiation and vetting.
Where suppliers are and what they make
SupplySpark lists 2,060 manufacturers in China with 72% carrying independent evidence such as registry, customs entries or reviewed credentials. Major city clusters on the platform include Guangzhou (187), Dongguan (175) and Shenzhen (132), with strong representation from Hangzhou (96), Wenzhou (93) and Shaoxing (93). In our experience Guangzhou, Dongguan and Shenzhen are dense for consumer electronics accessories and small molded parts, while Hangzhou, Wenzhou and Shaoxing typically host soft-goods and textile-related production. Representative profiles on the directory include acetate and metal optical frames, cosmetic pouches in PVC/EVA/TPU and silicone wristbands, illustrating the range of product types available.
MOQ and lead-time realities
Of the 1,429 suppliers that publish MOQ on SupplySpark, 753 list 50 units or fewer, 213 list 51–200 units, 237 list 201–500 units, 145 list 501–1,000 units and 81 list over 1,000 units. The directory also contains single-unit MOQs for some firms, for example suppliers in Shenzhen and Wenzhou advertising MOQ 1–2 for sample and small-batch items. Sampling services are commonly offered by suppliers, with 1,056 listing sampling as a service model. Lead times are not published uniformly on the dataset; typically expect one to four weeks for samples and four to twelve weeks for production depending on complexity and order size.
Certifications and compliance you will see
Common certifications shown across the supply base include ISO 9001 (659 suppliers), amfori BSCI (564), Sedex/SMETA (254), Global Recycled Standard (GRS) (246), ISO 14001 (213) and OEKO-TEX Standard 100 (162). Buyers sourcing contact-lens related or medical-adjacent items should note ISO 13485 appears on specific profiles. When you request documentation, ask for scanned certificates that show the scope and the issuing body and verify them against the issuer’s public registry or a third-party audit report.
Cost drivers and negotiation focus
Primary cost drivers are raw material selection, component complexity, tooling and surface finish, compliance testing and order quantity. Service models shown on SupplySpark indicate 1,390 suppliers offer OEM, 1,333 offer custom-design and 1,148 offer ODM, which affects pricing flexibility and tooling responsibility. Negotiate on clear points: minimum order, payment terms, who pays for tooling and first-article inspection, and volume discounts tied to defined quality thresholds. For recycled or certified materials plan for premium pricing, and request material declarations tied to the supplier’s GRS or OEKO-TEX certificates where applicable.
Quality control, logistics and vetting
SupplySpark shows a mix of Manufacturer & Trader (1,092) and pure Manufacturers (617), so confirm where production actually occurs and whether the contact is an intermediary. Ask for recent inspection reports and the supplier’s quality control process; many suppliers list sampling (1,056) and private-label (698) as services which facilitates pre-production checks. For logistics, confirm Incoterms early and verify HS codes for customs classification. Typical practice is to confirm third-party inspection acceptance criteria and to include holdback clauses or pre-shipment inspection milestones in contracts.
Questions to ask before you sample
- Can you provide scanned copies of your key certifications (for example ISO 9001, amfori BSCI, Sedex, GRS or OEKO-TEX) and the issuer’s contact details for verification?
- What is your published MOQ and what lead times do you commit to for samples and production runs of my quantity?
- Who is the legal manufacturer and where is production physically located; can you provide recent factory photos and a site audit report?
- What is your monthly production capacity for this SKU and what capacity guarantees can you provide for my launch window?
- Who pays for tooling, what are tooling costs, and what is the expected amortized cost per unit at different order bands?
- Can you share recent third-party inspection reports and do you accept buyer-designated inspectors for pre-shipment checks?
- What Incoterms do you prefer, what documents will you provide for export (commercial invoice, packing list, bill of lading) and who handles customs clearance?
