Trading companies are not automatically a problem in Chinese sourcing. The due diligence question is whether your intermediary adds real operational value or mainly conceals the factory relationship and marks up factory costs. To decide, verify what the company actually controls, request itemized cost and production evidence, and map the supply chain until you know who makes each critical component and who ships the finished product.
Why Trading Companies Exist in Chinese Sourcing
Trading companies aggregate suppliers, handle Chinese-language communication, consolidate orders, arrange inspection and export paperwork, and absorb some coordination risk. For a DTC brand with small volumes, multiple SKUs, or limited on-the-ground staff, that can be useful. The tradeoff is transparency: if the intermediary will not disclose the production site, you cannot benchmark factory costs, audit capability, or plan a direct relationship. A good decision criterion is whether the company performs services you cannot cheaply replicate—sourcing, sampling coordination, QC, consolidation, compliance documentation—rather than simply hiding the source. Your next step is to ask the trading company to document its role in each stage: sourcing, sampling, production, inspection, and export.
Signs Your Trading Company May Be Marking Up Factory Costs
Look for patterns, not one data point. Warning signs include:
- Lump-sum quotes with no material, processing, tooling, packaging, QC, or freight breakdown.
- Refusal to name the factory, share its address, or allow a live video call from the production floor.
- Vague explanations when samples and mass production come from different sites.
- “Our factory” language without a business license, production capacity evidence, or permission to audit.
- Price changes that are not tied to material, labor, or specification changes.
- Invoice entity, export documents, and production site do not align.
These signs are not proof of markup. Request an itemized quote and a structured explanation of each cost line. Pressing for transparency can strain the relationship, so frame it as a sourcing requirement rather than an accusation.
Mapping the Real Supply Chain Behind Your Product
Map one SKU before you switch suppliers. First, obtain a bill of materials and process route. Second, list every entity involved: trading company, assembly factory, component suppliers, packaging printer, and forwarder. Third, request business licenses, factory addresses, production line photos or video, and a live walkthrough. Fourth, cross-check labels, shipping documents, and invoices to confirm who produces, who exports, and who bills. The decision criterion is simple: can you trace every critical component to a named supplier? If not, you cannot reliably benchmark costs or audit quality. Going direct may raise MOQs, deposit requirements, and your own QC and logistics workload. If you want support mapping the chain before changing suppliers, you can start a project with Yoursender.
Verifying Business License and Manufacturing Scope
With a shortlist in hand, treat every supplier’s business license as a starting point—not proof that they make your product. Request a clear copy and match the legal name, unified social credit code, registered address, and legal representative to the quote, invoice, and contract.
- Cross-check the license against China’s National Enterprise Credit Information Publicity System. Confirm the company is active and the registered address is consistent.
- Read the business scope carefully. Look for manufacturing or production wording for your product category—not only wholesale, retail, import/export, or “technology” services.
- Match the registered address to the actual production site. If they differ, ask why and request the factory lease or site documentation.
- For regulated categories, ask for the relevant production license or permit and verify the product scope.
Decision criteria: the entity at the factory address has a manufacturing scope that covers your product. Risk: a trading company may present a factory license that belongs to a subcontractor, or a manufacturer may outsource your product without disclosure.
Factory Audit vs. Trading Company Visit
A showroom visit is not a factory audit. Trading companies can arrange factory tours, so confirm whose site you are standing in and which legal entity controls production.
| Check | Direct factory audit | Trading company visit |
|---|---|---|
| Legal entity at site | Factory license matches the address | Request the manufacturer’s license and relationship |
| Production control | Observe lines, QC area, warehouse, and sample room | Identify the actual factory for your product and audit that site |
| Ownership or lease | Request lease or property proof | Confirm whether they own, lease, or subcontract |
Use short-notice audits, walk the perimeter, check signage, and ask workers and managers who owns the facility. Review QC records and production orders. Risk: staged visits or a “borrowed” factory. Next step: if a trading company is transparent, you can keep them—but audit the actual manufacturer.
Checking Production Equipment and Capacity
Request an equipment list by process, including quantity, age, condition, and whether each step is in-house or outsourced. Ask for time-stamped photos or videos. Calculate capacity from shifts, line speed, yield, and bottlenecks—not the supplier’s headline number. Compare quoted lead times with their current order board and your 12-month forecast. Decision criteria: equipment matches your product and tolerances, capacity has cushion for peak season, and no critical process is hidden. Risks: overstated capacity, outdated equipment, or undisclosed subcontracting. Next step: schedule an audit and validate capacity against redacted production schedules.

Confirming Export and Certification Records
A trading company can show you a polished certificate pack that belongs to someone else. Your job is to confirm that the documents are held by, and apply to, the entity you are about to pay.
- Match names and addresses. Compare the certificate holder, the business license, the invoice issuer and the factory address you intend to audit. Any mismatch needs a written explanation, not a verbal one.
- Check scope, not just existence. A certificate may cover one product family, one model, or one production line. Confirm the standard version, issue date, expiry date and the exact product description against your specification.
- Verify independently. Look up certificate numbers in the issuing body’s public registry where one exists, and confirm test reports show an accredited laboratory, a report number and a sample description that matches your product.
- Request export evidence. Ask for redacted customs declarations or shipment records from the past 12–24 months, and check that destination markets and HS codes align with your category.
Decision criteria: the factory should be able to produce records within a few business days, explain gaps plainly, and show a path to any certification your market requires. Tradeoff: many capable factories will redact buyer names and volumes for confidentiality — accept redaction, but not silence. A factory with strong domestic sales and thin export records may still be a good partner; treat that as a planning risk to price in rather than an automatic rejection.
Testing Communication and Sample Control
Before you commit volume, run a short, low-cost test of how the factory communicates and how it controls samples.
- Send a technical question that only an engineer can answer, such as a tolerance or material substitution question, and note who replies and how precisely.
- Log response times across two to three weeks and multiple channels. Consistent next-business-day replies with clear ownership beat fast replies that contradict each other.
- Order a sample with one deliberate specification change. Observe whether the change is confirmed in writing, reflected in the sample, and documented in a revised spec sheet.
- Ask how the golden sample is stored and referenced during mass production, and whether samples are made on the same line and by the same team as production.
Risks: a strong sales contact can mask a weak internal handover, and voice-note communication leaves no record when specifications drift. Next step: score each candidate on documentation quality, engineering access and sample revision discipline, then schedule a video walkthrough of the sample area.

Negotiating the Transition Without Disrupting Supply
Treat the move from trading company to direct factory as a staged program, not a switch. First, qualify the factory with samples, document review, and a pilot order while your trading company continues to supply current SKUs. Decide the cutover point using explicit criteria: consecutive production lots that meet your quality standard, on-time delivery, complete compliance documents, and a signed manufacturing agreement. Keep a safety stock sized to your lead-time risk and cash position until the factory has proven repeatability.
Negotiate on total landed cost, not unit price alone. Compare piece price, tooling, MOQ, payment terms, freight, inspection, defect handling, and cash tied up in inventory. Ask for a written capacity commitment and a production schedule; confirm who covers expediting and how peak-season allocation works. Protect continuity by agreeing on a notice period, pending purchase orders, tooling handover, warranty obligations, and outstanding credits. Do not disclose final designs, BOMs, or customer data before an NDA is signed. Risks include hidden subcontracting, the trading company reducing support prematurely, and the factory prioritizing larger accounts. Mitigate with audit rights, subcontracting consent, change-control clauses, and a weekly tracker with one accountable contact on each side.
Documentation and Contract Terms for Direct Factory Deals
Build a document set that matches the risk of the product. Start with an NDA, then a manufacturing agreement covering scope, specifications, forecast basis, lead times, price-adjustment mechanism, payment terms, Incoterms, packaging, labeling, and compliance responsibilities. Add a quality agreement with an approved golden sample, inspection plan, defect classification, rework and return process, corrective-action timeline, and recall responsibility.
Address intellectual property and tooling explicitly: who owns molds, fixtures, designs, and revisions; where tooling is stored; how you can inspect or retrieve it; and whether the factory may use it for other customers. Require written approval for material, process, or production-site changes, followed by re-validation. Collect test reports, declarations, safety data sheets, and certificates of origin as applicable, and require record retention. Include warranty and remedies, indemnity for IP or compliance failures, termination rights, dispute resolution, audit rights, subcontracting consent, and confidentiality survival.

FAQs
Should we tell the trading company before the factory is qualified?
Usually no. Review your contract for notice and termination terms, qualify the factory first, and involve legal counsel before disclosing the move.
How many pilot lots should we require before cutting over?
There is no universal number. Define acceptance criteria in advance—critical defects, on-time delivery, documentation completeness—and require consecutive lots that meet them.
What if the factory refuses to sign an NDA?
Limit disclosure to non-sensitive information or walk away. Do not release drawings, BOMs, customer data
