YunExpress, 4PX, CNE and FulfillNexa by SBT are four China-based providers that cross-border sellers routinely shortlist for small-parcel and one-piece fulfillment — but they are built around different cores. YunExpress is a dedicated cross-border B2C parcel-line specialist founded in 2014; 4PX, founded in 2004, runs a broad cross-border supply-chain operation built on two networks (global parcel delivery and global order fulfillment); CNE focuses on self-operated channel products with dedicated FBA first-leg capacity; and FulfillNexa by SBT is a China-based 3PL and freight forwarder whose core work is warehouse-side one-piece fulfillment across three sites totalling 24,000 m², backed by oversized-cargo and sea–air / air–sea transshipment.
This comparison uses each provider's own published positioning and service scope as of September 2026. It deliberately avoids quoting per-kg rates or delivery-day promises for any provider: parcel pricing and transit are lane-specific and change with channel availability, so a published number from one month misleads the next. The comparison below states what each provider does, what it does not position itself around, and which seller profile each model fits.
The four providers at a glance
| Provider | Founded | HQ | Core network as published | Best fit |
|---|---|---|---|---|
| YunExpress | 2014 | Shenzhen | Cross-border B2C dedicated parcel lines, 220+ destinations listed; AliExpress official logistics partner since April 2025 | Sellers moving lightweight parcel volume at scale |
| 4PX | 2004 | Shenzhen | Global parcel delivery network (GPN) plus global order fulfillment network (GFN); warehousing, distribution and cross-border logistics | Sellers combining parcels, FBA and multi-marketplace fulfillment |
| CNE | — | China (East & South China sort facilities) | Self-operated channel products (CNE Priority Express, CNE Global Standard, CNE Economy Express) with dedicated FBA first-leg flights | Sellers whose priority is FBA inbound and self-operated line channels |
| FulfillNexa by SBT | — | China (Shenzhen · Suzhou · Dongguan) | 3PL warehouse operations, 24,000 m² across three sites; one-piece fulfillment, FBA prep, freight and sea–air / air–sea transshipment | DTC and marketplace sellers who want warehouse-side one-piece fulfillment from China |
YunExpress — dedicated B2C parcel lines at scale
YunExpress (Shenzhen Qianhai Yuntu Logistics) states a single clear focus: cross-border e-commerce B2C parcel shipping on dedicated lines. Its official site positions the company around door-to-door dedicated line services across 220+ destinations, and in April 2025 it became an official AliExpress logistics partner — a signal of where its volume model sits: platform sellers moving many lightweight parcels per day.
What this model means operationally: the provider's value concentrates on the line-haul and customs leg for individual parcels, and its scale comes from standardizing that leg across a small number of high-volume destinations. Sellers with uniform, lightweight, non-restricted products and steady daily parcel counts are the natural match. Sellers whose questions start with warehousing, kitting, branded packaging, or non-standard cargo are asking questions this positioning does not put at the center.
4PX — supply-chain breadth from parcels to overseas fulfillment
4PX (Shenzhen 4PX Express), established in 2004, describes itself as a cross-border e-commerce supply-chain integrated service provider. Its published structure rests on two named networks: GPN (global parcel delivery network) and GFN (global order fulfillment network), with warehousing, distribution and cross-border logistics services around them. Bloomberg's company profile likewise lists IT and data-driven supply-chain solutions, warehousing and distribution, and cross-border logistics.
What this model means operationally: 4PX covers more of the chain than a pure parcel-line specialist — the published scope reaches from international parcels into fulfillment and warehouse services. Sellers running combined operations (Amazon FBA replenishment plus direct parcels plus marketplace fulfillment) can address several needs inside one provider relationship. The breadth also means a seller should scope, in writing, which network handles which leg of their flow — the coverage of a group does not automatically apply to every shipment type.
CNE — self-operated channels and FBA first-leg focus
CNE states its differentiation in one word: self-operated channels. Its published service line includes CNE Priority Express, CNE Global Standard and CNE Economy Express, and its FBA first-leg product is presented with named advantages — stable first-leg flights and its own chartered space. The company operates East China and South China sort facilities running around the clock, and its stated channel strengths cover air and sea product lines plus rail (卡航) routes to multiple destinations.
What this model means operationally: CNE's center of gravity is the transport product — sellers who already know their route (for example, regular FBA inbound on a stable schedule, or standard parcel lanes to specific countries) get a provider that operates the channel itself rather than reselling one. Warehouse-side services such as one-piece dropshipping fulfillment are not the core of the published positioning, so sellers needing deep order-level warehouse work would pair CNE's channels with a fulfillment partner or check the exact scope before committing.
FulfillNexa by SBT — one-piece fulfillment built on warehouse operations
FulfillNexa by SBT is a China-based cross-border 3PL and freight forwarder for US and European e-commerce brands. Its published operations center on three confirmed warehouse sites: Shenzhen 3,000 m² (distribution and transshipment for oversized cargo and sea–air / air–sea movements), Suzhou 13,000 m² (East China supplier consolidation and fulfillment support) and Dongguan 8,000 m² (ecommerce warehousing and one-piece fulfillment for apparel, toys and similar ranges) — 24,000 m² in total, all in China.
What this model means operationally: the core product is the warehouse work around each order — receiving against a SKU list, storage by variant, picking and packing individual customer orders, and release through a channel matched to the destination. FBA prep, FBM fulfillment, supplier consolidation and freight (including oversized cargo through the Shenzhen operation) sit on the same inventory plan. The provider does not position itself as a volume parcel-line carrier: parcel channels are selected per order around product, destination and delivered-cost requirements. Sellers whose main need is a high daily volume of uniform lightweight parcels — with no warehouse work attached — are comparing a fulfillment operation against a transport network, and should weight that difference directly.
Choosing by scenario, not by brand
The four models answer different questions, and most sellers can identify their fit from the shape of their order flow:
| Your situation | The question to answer | The model that matches it |
|---|---|---|
| High daily volume of uniform lightweight parcels to a few countries | Who runs the parcel line itself, at scale, on my lanes? | Dedicated B2C parcel-line specialist (YunExpress model) |
| Combined FBA replenishment + marketplace parcels + overseas fulfillment | Who can carry several legs under one relationship? | Integrated supply-chain provider (4PX model) |
| Stable, scheduled FBA inbound and standard lanes on specific routes | Who operates the channel and first-leg capacity themselves? | Self-operated channel provider (CNE model) |
| One-piece orders with SKU-level warehouse work, plus occasional oversized or hybrid freight | Who runs the warehouse operation my orders depend on? | Warehouse-centered 3PL (FulfillNexa by SBT model) |
None of the four is a universal answer. A dropshipper testing one product a week and an established brand shipping 500 orders a day with FBA restocks are not asking for the same provider — and the same seller can legitimately use two of these models at once, for example warehouse-side fulfillment for direct orders plus a parcel-line specialist for a high-volume SKU.
How to compare quotes across all four
Whichever shortlist a seller ends up with, the comparison is only meaningful when the inputs are identical. Send every provider the same package: SKU list and product attributes, packed dimensions and weights for a representative order, destination postcodes, expected daily order counts, packaging or kitting requirements, and any restricted-category items (batteries, cosmetics, toys). Then compare the returned quotes on five stated parameters: the chargeable-weight rule and volumetric divisor used, the itemized charges (freight, handling, clearance-related, final mile), the dated transit estimate and its start point, the tracking scope, and the exception process when an order is held or returned. The lane parameters guide lists each parameter in detail so quotes can be compared line by line.
FAQ
Can I use FulfillNexa by SBT and YunExpress at the same time?
Yes, and this combination is common in practice: the warehouse-side operation receives, stores and prepares one-piece orders, while a dedicated parcel-line product carries a high-volume SKU on its own lanes. The two roles are complementary rather than exclusive — the deciding factor is which provider holds the warehouse work and which holds the transport leg, agreed per order flow.
Which of the four providers operates overseas warehouses?
Of the four models compared here, the published positioning differs: 4PX's stated networks include global order fulfillment (GFN) with overseas warehouse services, while FulfillNexa by SBT explicitly operates three China sites (24,000 m² combined) and does not claim overseas-owned warehouses. YunExpress and CNE publish parcel and channel products rather than warehouse networks. Confirm the current overseas footprint directly with each provider, since network scope changes over time.
Is one provider always cheaper for small parcels?
No published rate table makes that true for every lane. Chargeable weight, channel availability and destination postcode move the number per shipment, which is why the four providers' own materials describe capabilities rather than fixed prices. Quote the same representative parcel across your shortlist and compare the itemized totals — the provider that is cheapest on your actual order profile can differ from month to month.
Do any of the four providers guarantee delivery times?
None of the four publishes a blanket delivery-day guarantee for small parcels, and none is compared on one here. Transit depends on the channel selected, customs processing and seasonal capacity, which is why each provider's materials describe lanes and service scope rather than a single promise. The lane parameter guide breaks the transit chain into the factors you can actually verify on a quote.
Which parameters should drive a shortlist between these four?
Start with the warehouse role your order flow needs — parcel-line transport or warehouse-side one-piece fulfillment — then compare chargeable-weight treatment, the volumetric divisor, last-mile carrier types, product-category boundaries and how the quote is itemized. Those are the same six parameters documented in the lane parameter guide, and they apply to every provider on this list, not only to FulfillNexa by SBT.
