Mid-Autumn Festival 2026 falls on Friday, September 25. In mainland China the public holiday runs for three days, from September 25 to September 27, and normal business resumes on Monday, September 28.
On behalf of every engineer, technician, and colleague at TOBGROUP in Xiamen, we send our warmest greetings to the battery manufacturers, distributors, universities, and research institutes we serve worldwide. The holiday is short, but the production calendar around it is not, so this page also explains how our teams operate during those three days, how to reach us, and what our partners made possible this year.
Celebrating Mid-Autumn Festival 2026 with Our Global Partners
A festival greeting means very little without the people it is meant for. TOBGROUP has grown from a small battery equipment workshop into a full-range supplier of laboratory lines, pilot lines, and production lines because our partners kept raising the bar. This Mid-Autumn Festival 2026, we would rather say thank you in specifics than in slogans.
A Greeting to Our Customers
Whether you are commissioning a single coin cell lab line in a university laboratory or scaling a pouch cell plant toward gigawatt-hour output, you have trusted our engineers with timelines that could not slip. You have invited us into process discussions, shared yield data, and pushed us toward machine designs that hold tolerance run after run.
That partnership is the reason our company history reads less like a product catalogue and more like a 24-year engineering record, from electrode coating and calendering in 2002 to the turnkey lines we ship today. More than 8,000 customers across 100-plus countries and regions have worked with our equipment, and this Mid-Autumn Festival 2026 we want to say plainly that each of them shaped what we build next.
A Greeting to Our Distributors and Engineering Partners
Our distributors and engineering partners carry TOB equipment into markets we could never reach alone. Together we have commissioned lines across North America, Europe, India, Korea, Southeast Asia, and South America, in projects where local insight and our manufacturing depth had to work as one system.
More than 1,000 battery and PACK lab lines, pilot lines, and production lines have been delivered worldwide, and a good share began with a conversation a distributor started. As Mid-Autumn Festival 2026 approaches, that contribution is something we are genuinely grateful for.
A Greeting to Universities and Research Institutes
To the universities and research institutes that run our laboratory equipment every day: your experiments set the specification for the next generation of machines. Research groups working on solid-state electrolytes, sodium-ion chemistries, and lithium-sulfur systems have shown us exactly where commercial equipment still falls short.
We treat that feedback as a privilege rather than an inconvenience. When a graduate student tells our engineers that a dry-room process window is too narrow, the next revision of that machine reflects it, and that is the reason our equipment improves year after year.
What the Mid-Autumn Festival Means to International Partners
Many overseas partners ask, quite reasonably, what the Mid-Autumn Festival actually is, and why an entire country slows down for it. Understanding the festival explains a great deal about how business communication works in China during late September and early October. In short, Mid-Autumn Festival 2026 is a family holiday first and a public holiday second.
The Full Moon, Harvest, and Family Reunion
The Mid-Autumn Festival 2026 falls on the 15th day of the eighth lunar month, when the moon is at its brightest and roundest. In Chinese culture the full moon has always stood for completeness and togetherness, so the festival is built around going home: families travel long distances to share one meal under the same sky.
That framing matters for scheduling, because Mid-Autumn is built around private travel rather than public events. Factories and offices thin out rather than shut down completely, which is why an informed buyer plans for reduced capacity instead of total closure.
Mooncakes, Gifts, and Business Etiquette
No Mid-Autumn table is complete without mooncakes, dense round pastries filled with lotus seed paste, red bean, or salted egg yolk, traditionally sliced and shared so that everyone eats from the same cake. Businesses present mooncakes to clients, suppliers, and employees as a gesture of appreciation rather than a commercial gift.
If a Chinese partner sends you a mooncake box in September, the correct response is a sincere thank-you. If you are planning outreach, note that Mid-Autumn Festival 2026 is a genuine relationship-building window: a short greeting in the last week of September lands far better than an email sent in the middle of the holiday.
Mid-Autumn Festival 2026 Dates and the China Holiday Schedule
For partners planning production and logistics around the festival, the dates matter far more than the sentiment.
Official Mid-Autumn Festival 2026 Holiday Dates in China
Mid-Autumn Festival 2026 begins on Friday, September 25, the 15th day of the eighth lunar month. The mainland China public holiday runs from September 25 to September 27, three consecutive days, and offices, factories, and government services return to normal on Monday, September 28.
National Day follows closely on October 1, so many Chinese companies operate on a reduced schedule from the last week of September into the first week of October. Before committing a delivery milestone inside that window, check it against the official China public holiday calendar rather than assuming a single week off.
What the China Holiday Means for Battery Equipment Buyers
Practically, Mid-Autumn Festival 2026 affects the four things our customers ask about most: quotation turnaround, engineering replies, factory production scheduling, and outbound shipping.
Expect quotation and technical responses to be slower on September 25 to September 27, and to recover to normal on September 28. Assembly and testing at our Xiamen base continue on a planned shift arrangement, so equipment already in build is not disrupted. The steps most likely to slip by one to three days are third-party services: inspection, customs brokerage, and freight consolidation. If a shipment must leave before October 1, place the documentation request before September 24.
How TOBGROUP Supports You During the Mid-Autumn Festival Holiday
Our holiday arrangement is designed so that no partner is left waiting without knowing what is happening.
Sales and Technical Support During the Holiday
Our sales team and technical support engineers remain reachable by email and phone throughout Mid-Autumn Festival 2026, including September 25 to September 27. Amy Wang, our marketing director, and the duty engineering rotation monitor both channels daily. Enquiries received during the break are logged on arrival and answered in priority order once normal operations resume on September 28.
For urgent line-down issues such as a coating head fault, a winding tension problem, or a sealing parameter drifting out of specification, call the technical support line directly. That routes the problem to a duty engineer rather than a shared inbox, which is the difference between a same-day answer and a Monday answer.
Production, Order Handling, and Delivery Planning
Equipment already in production keeps its committed schedule. New orders placed between September 25 and September 27 are processed, but contracts, invoices, and shipping documents may be issued with a short delay.
Customers finalising a battery production line solution ahead of Mid-Autumn Festival 2026 should send their final utility, layout, and material specifications before September 24. For teams still at the evaluation stage, our solution pages and sample request form stay available at any time during the Mid-Autumn Festival 2026 holiday.
A Year of Progress: From Lab Line to Production Line
Mid-Autumn Festival 2026 is also a good moment to report honestly on the year. Here is what our customers and partners made possible.
24 Years in Battery Manufacturing Equipment
TOBGROUP was established as Xiamen TOB New Energy Technology Co., Ltd. in 2012, but our founding engineers entered the lithium battery field as early as 2002, which makes 24 years of accumulated process knowledge. That history covers lithium-ion, solid-state, sodium-ion, lithium-sulfur, and supercapacitor technologies, with equipment spanning material preparation, electrode coating and calendering, cell assembly, formation and grading, and testing.
The engineering is matched by verifiable systems: more than 60 national patents, ISO 9001, IATF 16949, ISO 14001, and ISO 45001 certification, CE and UL compliance, and an R&D and testing centre of more than 3,000 square metres that includes pilot lines and dry rooms rated to a minus 50 degree Celsius dew point.
Scaling from Laboratory Research to Pilot and Mass Production
The most common request we heard this year was for continuity: customers who validate a chemistry on a coin cell line and then need the same process to hold at pilot scale and again in mass production. Meeting that demand shaped our 2026 roadmap.
Our R&D centre now works across six research targets, covering high energy density, high C-rate, ultra-fast charging, long cycle life, low temperature, and high temperature, and translates each into a scalable process window rather than a laboratory demonstration. The goal never changes: a process window that survives the jump from a bench-top cell to a full production hall.
Solid-State, Sodium-Ion, and Lithium-Sulfur Capability in 2026
Our chemistry coverage widened again ahead of Mid-Autumn Festival 2026. For solid-state cells we work across sulfide, oxide, and polymer electrolytes, and our pilot lines integrate dry and semi-dry electrode fabrication, solid electrolyte layer formation, multilayer stacking, and high-pressure assembly.
For sodium-ion we cover Prussian blue analogues, layered oxides, and polyanionic cathodes together with hard-carbon anode engineering. University research feeds directly into this work: polyanionic cathodes with conductivity lifted by a factor of 1,000, high-nickel cathodes for all-solid-state cells, and oxide solid electrolyte processes now running on a 100-ton production line.
Growing Together: Research, Certifications, and Partnerships
Equipment alone does not move an industry forward. The knowledge behind it does, and so does the willingness to have that knowledge audited.
University Research Collaboration
TOBGROUP collaborates with global universities and research institutions through joint laboratory agreements. Our partnership with Central South University covers solid-state and sodium-ion technologies, with fundamental materials research and electrochemical evaluation on the university side and equipment engineering and process scale-up on ours.
The same model now operates with the University of Science and Technology of China and Tsinghua University. Our platform offers joint lab equipment, funded project slots, and priority access to a 1,000 square metre pilot base.
Certificates, Audits, and Third-Party Verification
Claims about quality are worth very little without independent verification. Our core equipment portfolio has held CE certification since 2015, our quality management system has been ISO 9001 certified since 2013, and in 2026 we were verified as a TÜV Rheinland certified supplier, a review covering manufacturing infrastructure, quality management, and export readiness.
Our certificate archive, including IATF 16949 and ISO 14001 and ISO 45001, is published in full so that procurement teams can check it before a purchase order.
The TOBGROUP Global Distributor Program
For partners who want to represent TOB equipment in their own markets, our Global Distributor Program provides technical training, demonstration support, spare-parts access, and joint project engineering. Flexible models cover exclusive territorial representation, non-exclusive agency, and project registration.
The appeal is straightforward: a complete range from coin cell laboratory equipment to full production lines, backed by a manufacturer that sends engineers on site and commits to a 24-hour response guarantee. Applications received during the Mid-Autumn Festival 2026 holiday are logged immediately and reviewed on September 28.
Mid-Autumn Festival 2026: Frequently Asked Questions
These are the questions international partners asked us most often in the weeks before Mid-Autumn Festival 2026.
When is the Mid-Autumn Festival in 2026?
Mid-Autumn Festival 2026 falls on Friday, September 25, 2026, the 15th day of the eighth lunar month. In mainland China the public holiday runs from September 25 to September 27. Because National Day begins on October 1, the two holidays sit close together, and many Chinese companies schedule reduced operations across the intervening week.
Do Chinese battery equipment factories close during the Mid-Autumn Festival?
Most manufacturers observe Mid-Autumn Festival 2026 as a statutory holiday but do not shut down completely. At TOBGROUP, sales and technical support remain reachable by email and phone throughout September 25 to September 27, while assembly and testing follow a pre-planned shift arrangement.
What partners should plan for is delay in external services rather than in production. Customs clearance, third-party inspection, and freight booking around Xiamen and Shenzhen are the steps most likely to slip by one to three days.
How can international partners reach TOBGROUP during the holiday?
Email and phone are monitored every day of the Mid-Autumn Festival 2026 holiday period. Urgent production issues should be raised by phone to the technical support line, so that a duty engineer responds directly instead of through a shared inbox.
Partnership enquiries, including distributor applications, can be sent at any time and will be answered once normal operations resume on September 28.
Warm Wishes from the TOBGROUP Team in Xiamen
Behind every machine we ship is a chain of people who decided to trust one another: a process engineer who shared a failing test result, a distributor who flew out to a customer site, a professor who let our engineers sit in on a laboratory meeting. Mid-Autumn is about returning to the people who matter, and that is exactly how we think of our partners.
A greeting is a small thing next to a commissioning schedule, so we will keep the rest practical. If you need a quotation, a layout review, or a spare part before Mid-Autumn Festival 2026 begins, send it this week and our engineers will have it in front of them on Monday, September 28.
From all of us in Xiamen, we wish you and your families a joyful Mid-Autumn Festival, a bright full moon, and a strong fourth quarter. If you would like to discuss a project, a pilot line, or a distribution partnership, contact us and we will be glad to pick up the conversation as soon as the mooncakes are finished.
