Choose a China 3PL by testing whether it can control the complete handoff from supplier receipt to export-ready shipment — not by comparing a single freight quote. A suitable partner should define who receives each SKU, how inventory is reconciled, what packing rules apply, who approves exceptions, which party owns customs data, and how proof is returned to your team.
Start with your operating model
Before contacting providers, write down the flow you actually need. A company importing pallets to one destination has different requirements from a seller releasing individual orders across several channels. The 3PL should be evaluated against that real flow, not a generic service list.
At minimum, define:
- where suppliers are located and how they will book deliveries;
- whether goods arrive as cartons, pallets, loose units, or oversized pieces;
- the SKU count, order profile, packaging rules, and sales channels;
- whether the next handoff is an Amazon fulfillment center, a carrier, a port, an airport, or an end customer;
- which party will be the importer of record and who will prepare each document;
- which events require photos, approval, escalation, or a hold.
This brief gives every candidate the same problem to solve. It also makes proposals easier to compare because differences in scope become visible.
Evaluate five points of control
Receiving and discrepancy handling
A provider should explain how it matches incoming goods to purchase orders or advance notices. Ask what happens when quantities, carton marks, dimensions, or visible condition do not match the expected record. The useful answer is a workflow: who records the discrepancy, what evidence is produced, whether stock is quarantined, and who can release it.
Avoid treating “warehouse received” as a complete status. Receiving should distinguish goods that have arrived from goods that have been counted, inspected to the agreed scope, identified, and made available for the next step.
Inventory identity and traceability
Ask how the warehouse separates sellers, SKUs, batches, and stock conditions. A practical system should prevent an unapproved substitution between similar products and preserve the relationship between a unit, its label, its order, and its outbound package.
You do not need to demand a particular software brand. You do need an agreed source of truth, a method for correcting discrepancies, and records that your team can review. If system integration is required, verify the exact fields and test method instead of accepting a broad claim that “all platforms are supported.”
Preparation and packing rules
Preparation must be driven by written specifications. These can include unit labels, carton labels, protective packing, kitting, repacking, measurements, or inspection checkpoints. The provider should identify which requirements come from your marketplace or carrier and which are internal warehouse controls.
For each rule, agree on the version, approval owner, acceptable evidence, and response when an item fails. This prevents an old label file or supplier assumption from becoming the warehouse instruction.
International handoff and customs data
A 3PL may coordinate freight, but the commercial parties still need to agree on responsibilities. Incoterms define selected delivery obligations; they do not replace product classification, valuation, admissibility, permits, taxes, or destination-specific rules.
For U.S. imports, CBP advises importers to understand commodity-specific requirements and makes clear that the importer of record remains responsible for entry information even when using a broker. Ask the provider to map the document owner for the commercial invoice, packing list, classification input, country-of-origin information, licenses where applicable, and transport instructions. Shipment-specific legal or tax questions should go to the appropriate licensed professional or authority.
Exceptions and communication
Normal orders reveal only part of a 3PL's capability. Ask candidates to walk through a shortage, damaged carton, unreadable barcode, missed collection, address correction, customs query, and customer return. For each event, confirm who notices it, who is informed, what evidence is sent, what options are offered, and who authorizes cost or rework.
A named escalation path is more valuable than a general promise of “full support.”
Match the facility to the cargo
FulfillNexa by SBT uses different operating roles across three confirmed China facilities totaling 24,000 m². Its 3,000 m² Shenzhen warehouse is near Shenzhen World Exhibition & Convention Center and the airport corridor; it is a logistics distribution center focused on oversized cargo and sea-air or air-sea transshipment operations. Its 13,000 m² Suzhou warehouse covers East China supplier consolidation and order fulfillment, reconciling inbound cartons from Yangtze River Delta suppliers against the agreed SKU list and storing them by variant. Its 8,000 m² Dongguan warehouse has a large operating floor and multiple loading bays and is focused on ecommerce warehouse management and one-piece fulfillment, including apparel and toys.
These facts describe intended facility roles; they do not by themselves prove that any of these sites fits a particular product, volume, compliance requirement, or departure schedule. A buyer should still request a shipment-specific operating plan and confirm where each activity will occur.
Run a controlled pilot before scaling
A pilot should test the most important handoffs, not merely send the easiest order. Select a representative group of SKUs and include at least one realistic exception. Give the provider the same files and approvals that would be used in normal operations.
During the pilot, review:
- how the inbound booking and receipt were recorded;
- whether SKU and quantity differences were identified correctly;
- whether labels and packing matched the approved instructions;
- whether carton dimensions and weights were captured consistently;
- whether the outbound handoff included usable tracking or transport references;
- whether photos and status records were clear enough for a remote team;
- whether an exception reached the right decision-maker before work continued.
The goal is not to manufacture a perfect demonstration. It is to learn whether the operating controls remain understandable when information is incomplete or something changes.
Documents to request and compare
Ask each shortlisted 3PL for documents that correspond to your flow. Appropriate items may include a sample receiving record, inventory status export, packing instruction template, inspection checklist, exception report, outbound handover record, claims process, and data-security explanation.
Licenses, registrations, certifications, insurance, or association memberships should be checked against the legal entity that will contract and invoice you. Record the issuing body, registration number, scope, and validity where relevant. A logo on a presentation is not sufficient verification.
China 3PL selection checklist
- Define the origin-to-destination flow and responsible parties.
- List product restrictions, handling risks, and required approvals.
- Confirm the facility and process used for every major activity.
- Agree on SKU, batch, carton, and order identifiers.
- Approve current label, packing, and inspection instructions.
- Map customs and transport data ownership without assuming the 3PL replaces the importer.
- Test integrations or file exchanges with sample data.
- Define evidence for receiving, rework, packing, and handoff.
- Document exception owners and escalation contacts.
- Review a representative pilot before increasing scope.
- Verify legal-entity documents and any claimed credentials.
- Compare the complete operating scope, exclusions, and decision points — not only the headline rate.
Make the decision on evidence
The best-fit China 3PL is the one whose facilities, controls, records, and escalation process match your actual cargo and sales model. A clear plan should show what happens before the goods arrive, while they are in the warehouse, at international handoff, and when an exception occurs. If those answers remain vague, more due diligence is needed before inventory is committed.
What to compare before inventory is committed
Two credible 3PL proposals are rarely comparable at the headline rate, because the rate is quoted against an assumed order profile, SKU count and exception volume. Fix the assumptions first and the differences become visible. CBP guidance for new importers makes the same point from the compliance side: responsibility for entry information stays with the importer of record even when a broker and a warehouse do the work, and Incoterms allocate selected delivery obligations without settling classification, valuation or admissibility.
| Question to answer | What changes the answer | Evidence to ask for |
|---|---|---|
| Which site receives this cargo? | Carton, pallet, loose-unit and oversized flows differ by facility | Named facility plus its dock, storage and handling limits |
| How is availability expressed? | Reserved, quarantined and in-transit stock may or may not reduce sellable quantity | A sample inventory export with the status field defined |
| Who releases an exception? | Damage, shortage and barcode failure each need a decision owner and a clock | Escalation list with names, channels and response windows |
| What does outbound proof contain? | A marketplace claim, a carrier reference and a customs record are three different objects | A completed handover record from a similar shipment |
| What is excluded from the rate? | Rework, holds, dim-weight correction and re-labeling are where quotes diverge | Written tariff of secondary charges and its effective date |
For the consolidation-specific failure modes behind one of these rows, see multi-factory consolidation control, and for how a small brand should read the resulting invoice, how China fulfillment costs are quoted. Amazon's own fulfillment overview is a useful neutral reference when you want the marketplace's definition of the scope rather than the provider's.
FAQ
What should be written down before contacting China 3PL providers?
The flow you actually need. Importing pallets to one destination and dispatching individual customer orders impose different requirements, and that operating model decides which facilities and controls matter.
Which points of control should be tested?
Receiving against an advance notice, what happens when quantities or dimensions disagree, how inventory status is expressed, how orders are released, and what the outbound record and escalation path look like.
Which FulfillNexa facility handles which cargo?
The confirmed 3,000 square meter Shenzhen warehouse sits near the Shenzhen World Exhibition and Convention Center and the airport corridor, supporting oversized cargo and sea-air or air-sea transshipment; the 13,000 square meter Suzhou warehouse covers East China supplier consolidation and fulfillment for Yangtze River Delta suppliers; and the 8,000 square meter Dongguan site carries ecommerce warehousing and one-piece fulfillment. Together the three sites cover 24,000 square meters.
What should a pilot actually prove?
The critical handoffs, using a representative SKU group and at least one difficult case, rather than the easiest order in the catalog.
How should two comparable 3PL proposals be set side by side?
Normalize the assumptions before the rates: identical SKU count, monthly order volume, average order size, packing scope and exception allowance. A cheaper per-order figure that assumes no kitting, no holds and no rework is not a lower price, it is a different scope, and the difference shows up later as secondary charges.
