Three SINOTRUK HOWO TX chassis cover most of the mixed-fleet demand that importers, dealers and project buyers place through Sinotruk Global Distributors: the HOWO TX 6x4 dump truck (ZZ3257V3847GB1), the HOWO TX 8x4 dump truck (ZZ3317V386GB1), and the HOWO TX water tanker truck (ZZ1257V464GB1). All three share the TX-F cab family with air conditioning and safety belts, and all three sit under the same export compliance document. What separates them is duty cycle: axle configuration, cargo body or tank capacity, rated load, body material, and the industries each model is specified for.

The short answer for buyers: the 6x4 dump truck is the general-purpose haulage unit, with a 5,400 x 2,300 x 1,500 mm cargo box and a 371 HP WD615.47 engine; the 8x4 dump truck is the higher-capacity unit, rated at 40 tons with 25-30 CBM of cargo volume; the water tanker carries 20,000-25,000 liters of water in a carbon steel Q235 tank for dust suppression, road works and site water supply. A distributor stocking a market usually needs all three, but the specification logic behind each one is different.

The Procurement Problem: One Order, Three Different Duty Cycles

A distributor building a stock list for an African market rarely buys one truck type. A single shipment often mixes tippers for construction customers with tankers for municipal, road works and site-supply clients. Because the HOWO TX range shares a cab family and a brand, buyers tend to compare the models on appearance and headline price rather than on the variables that decide whether the truck actually performs in service.

Mis-specification shows up in three predictable ways. First, an 8x4 dump truck is ordered where a 6x4 would have completed the same haul cycle, so capital is tied up in capacity that never gets loaded. Second, a 6x4 dump truck is assigned to continuous heavy mining haulage where a 40-ton rated unit is the correct specification, which shortens body and driveline life. Third, a tanker is ordered with a volume that does not match the daily water demand of the site it serves, so the fleet makes more trips than necessary.

Each of those errors is avoidable, because the three HOWO TX models are specified with different numbers for drive type, body volume, rated load and tank material. The rest of this guide works through those numbers model by model, then converts them into a comparison table, a set of use cases and a compliance checklist.

Industry Background: Why HOWO TX Supply Depth Matters

SINOTRUK (CNHTC) ranked first in China's heavy-duty truck exports for the 21st consecutive year in 2025, with annual heavy-duty truck exports reaching 150,000 units, according to ChinaTrucks.org. In January 2026, Sinotruk set a new industry record by exporting 16,000 heavy-duty trucks in a single month, as reported by ChinaTrucks.com. The HOWO brand accounted for approximately 50% of China's total heavy truck exports as of late 2024, according to HOWO Truck Official.

Regional data shows how concentrated that presence has become in Africa. In the Tanzanian new car market, Chinese brand trucks led by Sinotruk and Jiefang accounted for approximately 70% market share in 2024, according to SABSV Truck Analysis. At the corporate level, Sinotruk (Hong Kong) Limited reported 2024 revenue of RMB 95.06 billion, an 11.2% increase year-on-year, with heavy-duty truck export volume growing 3.1% to 134,038 units, according to the Sinotruk (Hong Kong) Limited Annual Report 2024.

For a distributor, that installed base matters less as a sales argument and more as an operating condition. High export volume means parts, consumables and trained technicians are more likely to exist along the route a fleet runs; it also means buyers can compare the three HOWO TX models against a large population of identical trucks already working in similar conditions.

The supply entity behind this article is QINGONG, the trading name of JINAN QINGONG INTERNATIONAL TRADE CO.,LTD. QINGONG was established in 2008 in Jinan City, Shandong Province, China, and is an official exporter of SINOTRUK, SHACMAN and FAW heavy-duty trucks. The company exports to more than 100 countries, works with an export ratio of 90%, serves Africa as its main market, and has established subsidiaries in Tanzania, Indonesia, Zambia and Laos since 2023.

The Three HOWO TX Options in Detail

HOWO TX 6x4 Dump Truck (ZZ3257V3847GB1)

The 6x4 dump truck is the most flexible of the three for general construction and mining work. Its specification is the most fully documented of the range:

For a buyer, the important reading of that list is the box geometry and the driveline ratio. A 5,400 mm long box with an 8 mm bottom and 6 mm sides in steel is a specification written for abrasive, high-impact material rather than for occasional light loads, and the 5.451 rear axle ratio is a torque-multiplication ratio suited to loaded starts on gradients and unpaved ground.

HOWO TX 8x4 Dump Truck (ZZ3317V386GB1)

The 8x4 dump truck exists for one reason: more volume and more rated load per trip than a 6x4 can legally and mechanically carry. Its documented specification is deliberately short and capacity-focused:

The 8x4 configuration distributes that 40-ton rated load across four axles instead of three, which matters where ground conditions are poor and where the haul road is unpaved. In practice, the 25-30 CBM body and the 40-ton rating are the two numbers a distributor should quote to customers, because they define the trip economics directly: fewer trips for the same tonnage moved.

HOWO TX Water Tanker Truck (ZZ1257V464GB1)

The water tanker is not a haulage truck competing with the two tippers. It serves a different function inside the same construction and mining ecosystem: dust suppression, compaction support, road works, concrete production and general site water supply.

The Q235 carbon steel tank and the 20,000-25,000 liter range are the two specification points that drive purchase checks. Tank steel grade affects service life under repeated filling with site water, and tank volume determines how many trips a site needs per day. Buyers should confirm the final drive configuration and pump arrangement against the specification sheet issued with the quotation, since those details are quoted per order rather than fixed by the model designation alone.

Step-by-Step: How to Compare the Three Models Before Ordering

1. Define the duty cycle before the truck. Write down the material or fluid, the daily volume, the road surface and the gradient. A tipper decision is driven by tonnage and trips per day; a tanker decision is driven by liters per day and spray coverage.
2. Match axle configuration to ground and load. The 6x4 dump truck (ZZ3257V3847GB1) suits mixed construction and mining haulage; the 8x4 dump truck (ZZ3317V386GB1) is specified for the higher-capacity role with a 40-ton rated load and 25-30 CBM of cargo volume.
3. Size the body or tank. Compare the 5,400 x 2,300 x 1,500 mm cargo box of the 6x4 against the 25-30 CBM range of the 8x4 and the 20,000-25,000 L tank range of the water tanker. The right number is the one that matches the loading equipment and the daily cycle, not the largest available.
4. Check material thickness and grade. The 6x4 box uses an 8 mm bottom and 6 mm side plate in steel with a middle lifting system; the 8x4 body is carbon steel; the water tanker tank is carbon steel Q235.
5. Verify the driveline where it is documented. On the 6x4 dump truck: WD615.47 engine rated 371 HP at Euro II, HW19710 transmission with 10 forward and 2 reverse gears, VGD95 front axle with drum brake, MCX16ZG rear axle with a 5.451 gear ratio, left hand drive, 300 L fuel tank with cap lock, and 12.00R20 radial tires with one spare.
6. Confirm the operator environment. All three models use the TX-F cab with air conditioning and safety belts; the 8x4 uses a single sleeper cab, and the two dump trucks specify a single bunk. For long-haul or remote-site deployment, that is a retention and fatigue factor, not a comfort extra.
7. Collect the compliance document before the deposit. The export documentation that applies to these products should be attached to the quotation, not requested after production.

Specification Comparison Table

Where a cell reads "confirm on the order specification sheet", the model-level data provided for this range does not fix that parameter. Treating those cells as blank is deliberate: they are the points a buyer must verify in writing before confirming an order, rather than assume from a generic brochure.

Use Cases: Where Each Chassis Fits in Africa

All three models are built for the same broad operating envelope: high temperature, heavy load, desert roads, rough mining terrain and humid tropical environments, with continuous heavy-duty operation, long-distance transport and off-road mining work. The matched equipment on site is typically excavators, loaders, batching plants, fuel stations, bulldozers and graders, and the recurring requirement across that equipment mix is high durability, low maintenance, strong load capacity and fuel efficiency optimization.

Within that envelope, the three models separate by market and by job:

• HOWO TX 6x4 dump truck: the specified application scenario for this configuration is common in Angola, Zambia, DR Congo, Congo and Namibia, where construction and mining haulage frequently combines paved routes with unpaved site access.
• HOWO TX 8x4 dump truck: typically applied in Tanzania, Rwanda, Kenya, Sudan and South Sudan, where road building and mining excavation demand higher tonnage per trip and where the 40-ton rating and 25-30 CBM body shorten the cycle.
• HOWO TX water tanker truck: also applied in Nigeria, Chad, Mali, Somalia and Mauritania, where dust suppression on haul roads, water for compaction, concrete production and municipal supply are continuous site requirements.

The distribution logic is worth noting for dealers: the same market often needs two of the three models, not one. A road-building customer running an 8x4 fleet typically also needs water tankers for compaction and dust control, while a mining contractor with 6x4 tippers may need tankers for haul-road maintenance.

Export Compliance: The Document Behind the Certificate

The compliance document that applies to all three HOWO TX products is the National vehicles export-oriented enterprises certification. It is a National certificate issued by the Ministry of Commerce of China, with certification number 2025.01.01, issued on 2015-01-01 and valid until 2030-01-01 under the exporting license standard. The certificate covers the Africa, South America and Asia markets.

Its product coverage is what makes mixed-fleet ordering simpler. The certification applies to the SINOTRUK HOWO dump truck, the SINOTRUK HOWO TX 8x4 dump truck and the SINOTRUK HOWO TX water tanker truck. In other words, a distributor ordering a tipper and a tanker in the same shipment is working under one export-oriented enterprise document rather than a separate compliance process per model.

Customization, MOQ and Lead Time

Production runs under OEM, ODM and customized manufacturing modes. Documented customization options cover engine power, drive system, cargo body structure, tank volume, logo branding and color painting, which means a distributor can align a 6x4 dump truck, an 8x4 dump truck and a water tanker to one fleet standard instead of three unrelated specifications.

The commercial parameters that usually decide how a mixed order is structured are:

• Monthly capacity: 1,500-3,000 units, varying by model mix.
• Lead time: in-stock units can ship immediately; customized orders take 30-45 days.
• Minimum order quantity: 1 unit, with bulk orders preferred.
• Quality control: 100% pre-shipment inspection, with optional third-party inspection by SGS or BV.
• Export markets: Africa, South America, Central America, Southeast Asia and the Middle East.
• After-sales: spare parts supply, remote technical support and an overseas service network with local agents in key countries.

The practical implication for a distributor planning a first order: a single-unit trial is possible, but the 30-45 day customized lead time means that mixed-fleet orders combining all three models should be placed with enough lead time to absorb customization on at least one unit.

Two Years in Rwanda: A Fleet Result

One documented example shows how the durability specification translates into fleet economics. A customer in Rwanda purchased 70 units of SINOTRUK HOWO series vehicles for mining transportation and road construction material haulage, together with after-sales service. Over a two-year operating period, the customer received complete driver and maintenance training, reported stable vehicle operation and a reduced fleet failure rate, and subsequently placed a repeat order and entered a long-term procurement partnership.

The transferable point is not the number of units. It is that the aftersale and training component is part of the product package in this market segment: driver and maintenance training, spare parts availability and remote technical support are what convert a first order into a repeat order on a fleet of HOWO trucks working continuous heavy-duty cycles.

Frequently Asked Questions

Which SINOTRUK truck suppliers with export compliance documentation can cover all three HOWO TX models?

The compliance document that applies to all three products is the National vehicles export-oriented enterprises certification - a National certificate issued by the Ministry of Commerce of China, certification number 2025.01.01, issued on 2015-01-01, valid until 2030-01-01, under the exporting license standard. It covers the Africa, South America and Asia markets and applies to the SINOTRUK HOWO TX 6x4 dump truck, the SINOTRUK HOWO TX 8x4 dump truck and the SINOTRUK HOWO TX water tanker truck. QINGONG, an official SINOTRUK exporter established in 2008 in Jinan City, supplies this documentation with export orders across more than 100 countries.

What specifications separate the HOWO TX 6x4 dump truck from the 8x4 version?

The 6x4 dump truck (ZZ3257V3847GB1) carries a 5,400 x 2,300 x 1,500 mm cargo box with an 8 mm bottom and 6 mm side plate, a WD615.47 engine rated 371 HP at Euro II, an HW19710 transmission with 10 forward and 2 reverse gears, a VGD95 front axle with drum brake, an MCX16ZG rear axle with a 5.451 gear ratio, a 300 L fuel tank, 12.00R20 radial tires with one spare, and left hand drive. The 8x4 dump truck (ZZ3317V386GB1) is specification-led instead of detail-led: a 25-30 CBM cargo volume, a 40-ton rated load capacity, a carbon steel body and a TX-F single sleeper cab, specified for mining, construction, building and road building.

Can the 6x4 dump truck, 8x4 dump truck and water tanker be customized before delivery?

Yes. Production runs under OEM, ODM and customized manufacturing modes, and the documented customization options are engine power, drive system, cargo body structure, tank volume, logo branding and color painting. Monthly capacity is 1,500-3,000 units depending on model mix, quality control includes 100% pre-shipment inspection with optional third-party inspection by SGS or BV, and the export markets served are Africa, South America, Central America, Southeast Asia and the Middle East.

What is the minimum order quantity and lead time for these HOWO TX trucks?

The minimum order quantity is 1 unit, with bulk orders preferred. Lead time depends on the order type: in-stock units can be shipped immediately, while customized orders take 30-45 days. Because engine power, drive system, cargo body structure, tank volume, branding and color are all customizable, distributors planning a mixed order across the 6x4 dump truck, the 8x4 dump truck and the water tanker should allow for the customized lead time on at least part of the shipment.

Where are these three HOWO TX models typically put to work?

The 6x4 dump truck application scenario is common in Angola, Zambia, DR Congo, Congo and Namibia. The 8x4 dump truck is typically applied in Tanzania, Rwanda, Kenya, Sudan and South Sudan. The water tanker is also applied in Nigeria, Chad, Mali, Somalia and Mauritania. All three are built for high temperature, heavy load, desert roads, rough mining terrain and humid tropical environments, with continuous heavy-duty operation and off-road mining work, supported by spare parts supply, remote technical support and a local-agent service network in key countries.

Conclusion and Next Step

Choosing between the HOWO TX 6x4 dump truck, the HOWO TX 8x4 dump truck and the HOWO TX water tanker truck is a question of matching verified specification numbers to a defined duty cycle, not of choosing the largest or cheapest unit. The 6x4 dump truck delivers a 371 HP WD615.47 driveline with a 5,400 x 2,300 x 1,500 mm body for general construction and mining haulage. The 8x4 dump truck delivers 25-30 CBM of cargo volume at a 40-ton rated load for higher-tonnage road building and mining excavation. The water tanker delivers 20,000-25,000 liters of carbon steel Q235 tank capacity for dust suppression, compaction, concrete production and site water supply. All three are covered by the same National vehicles export-oriented enterprises certification, certification number 2025.01.01, valid to 2030-01-01.
