Industrial project procurement
China and Asia sourcing platforms: what to define before you contact suppliers
Marketplaces make it easier to find manufacturers in China and across Asia. They cannot write your requirements, set your decision criteria or compare offers on your terms. This guide explains the main platforms fairly, then shows the project work that should come first.
Short answer
Use sourcing platforms such as Alibaba.com, 1688.com, Made-in-China.com, DHgate and Global Sources to discover options. Before you contact suppliers, define the business outcome, capacity, technical specification, compliance, budget, timeline, site constraints, service needs and total landed and lifecycle cost. Then send one structured RFQ, compare replies like-for-like, close the gaps and shortlist manufacturers that fit.
The China and Asia B2B sourcing landscape
Industrial buyers looking for China manufacturers or Asian suppliers usually meet the same handful of large platforms first. They are examples of major sourcing routes, not a complete list—regional marketplaces, industry associations, trade fairs and direct manufacturer websites matter too. The table summarizes how each platform describes itself on its own pages, reviewed on 14 October 2026.
| Platform | Start date | Role today (as the platform describes it) |
|---|---|---|
| Alibaba.com | Launched 1999 as Alibaba Group's first business | Global B2B platform offering sourcing, online transactions, digital marketing, supply-chain fulfillment and after-sales support (Alibaba Group) |
| 1688.com | Founded 1999 | China's integrated domestic wholesale marketplace, which has expanded from B2B trading into procurement services (Alibaba Group) |
| Made-in-China.com | Founded 1998; operated by Focus Technology | Global B2B trade site; its homepage currently offers an AI search mode and image search, and lists trade-show activity (about, homepage) |
| DHgate | DHgate Group founded 2004 | Cross-border B2B ecommerce transaction and service platform for small and medium retailers (DHgate) |
| Global Sources | Trade publication from 1971; online platform launched 1995 | Hong Kong-based sourcing business combining an online platform, apps, trade shows and business matching across Asian supply (Global Sources) |
Takeaway: Separate company founding dates from platform launch dates, and treat every feature description as the platform's own statement.
From directories to fuller trade services
Early B2B sites were largely catalogues and contact directories. Today several describe a wider journey. Alibaba.com lists transactions, fulfillment and after-sales alongside sourcing. Made-in-China.com promotes AI-assisted and visual product search. Global Sources links online sourcing with physical trade shows, an online-to-offline model. DHgate focuses on smaller cross-border wholesale orders, and 1688.com serves China's domestic wholesale market.
These changes help buyers find and contact suppliers faster. They do not change who is responsible for the project definition. The buyer still decides what the equipment must achieve, under which site conditions, at what total cost and with what evidence of acceptance.
What marketplaces solve—and what they do not
Marketplaces are strong at discovery: broad supplier reach, product listings, messaging, and in some cases payment and logistics services. For standard components or catalogue products, that may be most of the job.
- They do not know your required output, product variation or operating hours unless you specify them.
- Listings rarely show how equipment integrates with your utilities, building, upstream and downstream processes.
- Supplier quotes arrive in different formats, with different inclusions, Incoterms and exclusions.
- A verified-supplier badge describes the platform's own checks; it does not replace your due diligence, factory audit or acceptance test.
- Multi-supplier turnkey or engineering solutions need interface ownership, milestones and change control that sit outside a product listing.
Before you contact suppliers: the project brief checklist
Complete this brief first. Use “unknown—owner/date” where data is missing rather than leaving gaps for suppliers to fill. The RFQ readiness score shows what is still missing.
| Item | Define before contact | Evidence to keep |
|---|---|---|
| Business outcome | The result the project must deliver and how it is measured | Baseline data and target KPI |
| Capacity | Throughput, product mix, shifts and peak conditions | Production records or forecast basis |
| Technical specification | Mandatory requirements vs preferences; materials, tolerances, automation level | Approved user requirement specification |
| Compliance | Applicable safety, hygiene, electrical and import rules | Confirmation from qualified local specialists |
| Budget | Planning range for equipment, installation and integration | CAPEX calculator estimate with assumptions |
| Timeline | Required start-up date and fixed constraints | Milestone plan with dependencies |
| Site constraints | Space, access, foundations, power, water, air, drainage | Site survey and drawings |
| Service needs | Installation, commissioning, training, spares and response times | Service scope in the RFQ |
| Total landed and lifecycle cost | Freight, duties, insurance, installation, energy, maintenance, downtime | TCO calculator scenario |
A repeatable sourcing workflow
- Write the project brief and approve the mandatory requirements internally.
- Turn it into one structured RFQ with a common response format. The RFQ builder and example RFQs help as an RFQ template.
- Use marketplaces, trade fairs, associations and referrals to build a long list of relevant manufacturers.
- Send the same RFQ revision to every candidate and log questions and answers for all bidders.
- Normalize offers: currency, Incoterms, scope, exclusions, installation and operating assumptions. Our manufacturer comparison guide and buyer decision tools support like-for-like supplier quote comparison.
- Verify shortlisted suppliers: references, factory capability, certificates and financial standing, using independent checks where the risk justifies them.
- Agree milestones, change control and acceptance tests before ordering; the factory acceptance test checklist gives a structure.
- Track delivery, installation, commissioning and early performance against the original brief.
Common buyer mistakes and how to avoid them
| Mistake | Mitigation |
|---|---|
| Messaging suppliers before requirements are written | Finish the brief first; share one controlled RFQ |
| Comparing headline unit prices | Compare total landed and lifecycle cost on the same scope |
| Treating platform badges as full verification | Run your own supplier verification proportional to risk |
| Leaving interfaces between suppliers undefined | Assign an owner to every mechanical, electrical and control interface |
| Accepting vague delivery terms | State Incoterms, delivery evidence and installation responsibility |
| No acceptance criteria before payment milestones | Link payments to agreed FAT, SAT and performance tests |
Where Global B2B Group fits: a procurement operating system before and across supplier conversations
Global B2B Group is the supplier-neutral parent platform for industrial project procurement across manufacturing and agriculture. Its role sits before and alongside supplier conversations: project scoping, practical calculators and guides, a structured RFQ, offer comparison, supplier discovery and project tracking from brief to acceptance. See how this applies to manufacturing projects and why it differs from a supplier directory.
Marketplaces remain useful discovery channels alongside this process. Once the need is specified, our project team can, on request, contact suitable manufacturers on your behalf and bring back comparable responses. You stay in control of whether and whom to select. Specialist cold-chain, aquaculture, hatchery, seed and feed projects are routed to the relevant sister platform.
Limitations and editorial note
Platform descriptions come from each platform's own pages, reviewed on 14 October 2026; features and policies change. We do not rank the platforms, report their current performance or claim any partnership, integration or exclusive access. Nothing here requires you to use Global B2B Group. Compliance, tax and engineering questions need qualified local specialists. Prepared by the Global B2B Group project team.
Frequently asked questions
Which China sourcing platform is best for industrial equipment?
It depends on the product and project. Catalogue items may suit a marketplace; multi-supplier lines need a written brief, structured RFQ and comparison regardless of where suppliers are found.
What is the difference between Alibaba.com and 1688.com?
Alibaba.com is Alibaba Group's global B2B platform launched in 1999. 1688.com, also founded in 1999, is its integrated domestic wholesale marketplace serving China.
How do I compare supplier quotes from different platforms?
Send the same RFQ, then normalize currency, Incoterms, scope, exclusions, installation and operating cost before scoring technical fit and service.
Does a verified supplier badge replace supplier verification?
No. It reflects the platform's own checks. Confirm references, capability, certificates and acceptance testing yourself in proportion to the project risk.
Is Global B2B Group free for buyers?
Yes. Buyer tools and guidance are free, with no platform fee to buyers and no obligation. Optional assisted sourcing applies to projects of USD 250,000 or more.
