Two ASRS quotations from China can look surprisingly similar.
Both may include Shuttle Robots, racking, lifters, conveyors and software. Both suppliers may promise the required storage capacity and throughput. Even their equipment specifications can be close.
The differences usually appear later.
One proposal may have been developed around the actual pallet flow, SKU structure and peak workload. Another may simply have been assembled from standard equipment. One supplier may be able to modify its software around the customer's existing ERP or WMS. Another may discover interface problems only during commissioning.
For a buyer, this is what makes selecting a China ASRS manufacturer difficult. You are not really comparing machines. You are trying to judge how well a supplier can handle a warehouse project that has not yet been built.
Give the Same Warehouse Data to Each Supplier and Compare What Comes Back
A useful comparison starts before the quotation.
Send shortlisted manufacturers the same basic information: warehouse dimensions, clear height, pallet or tote specifications, load weight, SKU quantity, required capacity, inbound and outbound volume, peak workload and any special operating conditions.
Then look at what happens next.
A manufacturer with project-planning experience will usually ask more questions. How many pallets are normally held for each SKU? Does the customer require FIFO? Is the quoted outbound volume an eight-hour average or concentrated into a short shipping window? Are columns or fire zones restricting the rack layout? Will the automated warehouse supply production directly?
Those questions matter because a storage target alone does not determine an ASRS.
We can see this clearly in two automotive parts projects completed by DELIECN.
Toyota had a very large SKU population and frequent small-parts picking, but the available building height did not favor simply extending the storage system upward. The Mini-FlyBox area was therefore divided around different tote heights. H300 totes use a 15-level layout, while H450 totes use 11 levels. Together, the system provides more than 17,000 tote locations.
At another automotive component project, the physical conditions were almost the opposite. The Yonggui warehouse reaches 22.3 meters. There, a 51-level Tote Four-Way Shuttle AS/RS makes use of the available vertical space.
If a manufacturer recommends essentially the same configuration for these two buildings, the problem is not the equipment specification. The problem is the design logic.
Spend More Time on the Layout Than on Robot Speed
During early supplier comparisons, buyers naturally focus on numbers that are easy to place in a spreadsheet: travel speed, acceleration, load capacity and positioning accuracy.
They matter, but they rarely tell you whether the whole warehouse will achieve the required throughput.
Take a pallet four-way shuttle system. A robot may complete its rack movement quickly and still wait at a lifter. Several robots may reach the same transfer point within a short period. At the outbound end, conveyors or AMRs must be ready to receive the pallets. During peak shipping periods, these interactions become much more important than the maximum speed printed in the robot specification.
This is where the supplier's layout and simulation work deserve close attention.
Ask how the throughput figure was calculated. Ask where pallets are expected to queue. Ask what happens when several outbound tasks are released together. If the warehouse expands later, find out whether additional robots can actually increase capacity or whether the existing lifters and transfer stations will become the limit.
A good proposal should survive these questions without immediately returning to the product brochure.
Find Out What the Factory Actually Makes
Visiting the manufacturer's factory is especially valuable when sourcing an ASRS from China.
Do not spend the entire visit in the showroom.
Look at what is being assembled. Ask which products are manufactured there and which are purchased from outside suppliers. See whether Shuttle Robots, stacker cranes or conveying equipment are undergoing testing. Talk about software commissioning as well as mechanical production.
There is nothing inherently wrong with an ASRS containing equipment from several suppliers. Large automation projects often do.
The concern is responsibility.
If a pallet repeatedly stops between a shuttle and a lifter, who investigates it? If WCS has released the task but the PLC has not completed the sequence, which engineering team owns the problem? Overseas customers should know this before commissioning begins.
DELIECN keeps the development and manufacturing of major ASRS equipment and WMS/WCS within its own technical system. In practice, the advantage is less about having a longer product list and more about reducing the number of boundaries that have to be crossed when a problem involves both equipment and software.
Bring Your IT Team Into the Discussion Early
Software integration is one area where apparently similar ASRS quotations can turn into very different projects.
A manufacturer should first understand what the customer already has.
If the factory operates ERP and MES but does not have Warehouse Management software, WMS may need to become part of the project. If the customer already has its own WMS, installing another WMS simply because it is included in the supplier's standard package can create unnecessary complexity.
In that situation, the existing WMS can communicate with the automation layer, while WCS coordinates the physical equipment.
This was relevant in the Toyota project. Existing business and Warehouse Systems had to remain part of the architecture, so automation was integrated downstream rather than forcing the customer to rebuild its established information structure.
For buyers, an early interface meeting can reveal a great deal about a supplier. Bring the ERP, MES or WMS team into the conversation and ask the manufacturer to draw the proposed data flow. It is much easier to resolve ownership of orders, inventory and equipment tasks on a diagram than during site commissioning.
Ask to See a Project That Is Difficult in the Same Way as Yours
“Have you built an ASRS before?” is too broad a question.
A more useful request is:
Show me a completed project where the difficult part was similar to ours.
For a cold store, that could mean long-term operation below zero rather than simply high storage density. DELIECN, for example, has a pallet four-way shuttle project operating at -25°C. That experience is relevant to another freezer project because low temperature changes equipment selection, electrical components, battery performance and maintenance conditions.
A pharmaceutical manufacturer should look for experience with batch management, traceability and production supply. A factory with many material types should look for evidence that the supplier can coordinate different storage and handling technologies rather than forcing everything into one ASRS format.
The closest project does not have to come from exactly the same industry. What matters is whether the supplier has already dealt with the engineering problem that carries the most risk in your warehouse.
The Cheapest Difference Usually Appears Before the Most Expensive One
Price still matters. ASRS has to produce a reasonable return on investment.
But compare what is included before comparing the final number.
Detailed engineering, factory testing, installation supervision, commissioning, software interfaces, training, spare parts and after-sales support may be handled very differently by two Chinese manufacturers.
This matters more for an overseas project because solving a problem after shipment is considerably harder than solving it in the factory.
Before placing the order, it is worth knowing who will support commissioning, what can be diagnosed remotely, which spare parts should remain on site and how an issue is escalated when remote support cannot solve it.A small saving at purchase is easy to measure. The cost of a delayed production start or an ASRS waiting several days for technical support is not.
FAQS

The ASRS market is projected to grow over 10% annually by 2026 due to increasing demand.
Robotic automation reduces errors and speeds up operations, making it a valuable asset in Asrs Systems.
Customization allows tailored solutions to meet specific operational needs, improving efficiency significantly.
Total cost of ownership includes maintenance and updates. Understanding it helps avoid unexpected expenses later.
Evaluate if the system can adapt to increasing demands through hardware or software upgrades.
Examine responsiveness and customer reviews. Good support is crucial for long-term functionality and satisfaction.
Yes, while the initial cost may be higher, advanced technology can lead to significant long-term ROI.
Underestimating complexity and lacking a solid support plan can lead to costly downtime and inefficiencies.
Reflect on customization options, check real-world applications, and assess the manufacturer's track record for insights.
Conclusion
There is no single China ASRS manufacturer that is automatically the best choice for every warehouse.
A cold store with deep batches, a 22-meter component warehouse and an automotive spare-parts center with tens of thousands of SKUs should not arrive at the same design simply because all three customers asked for “warehouse automation.”
So before making the final comparison, put the equipment price aside for a moment and read the proposal as an engineering document.
Does the storage layout reflect your SKU structure? Does the throughput calculation include the busiest operating period? Can the manufacturer explain the bottlenecks? Does the software architecture fit the systems you already use? Has the supplier delivered something with similar operating difficulty? And when the warehouse is running several years from now, who will still be able to support it?
If those answers are clear, the quotation becomes much easier to judge.
For an overseas buyer, that is often the most practical way to choose a China ASRS manufacturer: understand how the supplier thinks about your warehouse before deciding how much its equipment is worth.
