Deep Dive: Mini Excavators Under 10 Tonnes
The CAT 306E2, CAT 307E2, and CAT 307.5 are all mini class machines under 10 tonnes. They are designed for work where space is tight: utility trenches, small foundations, landscaping, and indoor or confined sites. Because they are compact, they are easier to transport and can often be moved on a standard low-bed trailer without special permits.
-
CAT 306E2 (2022, 800 h, $16,000 FOB): This is the lowest-priced mini in the current stock. It has the highest hour reading of the three minis, but it remains a 2022 machine with only 800 hours on the meter. For a buyer who needs a reliable mini for light digging and utility work, this unit offers a straightforward entry point. The price reflects its slightly older year and higher hours compared to the other minis.
-
CAT 307E2 (2025, 500 h, $17,000 FOB): For an extra $1,000 over the 306E2, you get a 2025 machine with 500 hours. The 307E2 is a slightly larger mini than the 306E2, giving a bit more reach and lift capacity while staying under 10 tonnes. It is a good middle ground for contractors who want a nearly new machine without paying the premium of the 307.5.
-
CAT 307.5 (2025, 500 h, $26,000 FOB): This is the most expensive mini in the group, and the price difference reflects its newer design and additional features. The 307.5 is built for tight-access jobs and offers improved hydraulic performance and operator comfort compared to earlier models. If your work involves precision digging in confined spaces and you want the latest mini platform, this is the unit to consider.
All three minis are in stock. You can see a start-up video, photos, and an inspection report of the actual machine before you commit. The year and hours are provided as a reference, not as a guarantee of use.
Deep Dive: The 20–30 Tonne Class – CAT 320DIMPORT
The CAT 320DIMPORT is a different class of machine. At 20–30 tonnes, it is built for heavy digging, trenching, and large site work. The specific unit in stock is a 2011 machine with an 8,000-hour meter reading and a Grade B condition rating. The FOB price is $15,000.
This excavator is best suited to buyers who need a workhorse for bulk earthmoving, road construction, or quarry work. The 8,000 hours indicate the machine has seen significant use, but the Grade B rating suggests it is still serviceable and ready for work after normal maintenance. Because it is a larger machine, shipping costs will be higher than for a mini excavator. You will need to account for heavy-lift port handling and possibly a flat-rack or break-bulk vessel, depending on your destination.
As with the minis, this is a single unit priced on its own. You can request a start-up video, photos, and an inspection report. The year and hours are given as a reference only.
Cost, Quality, and Lead Time
When comparing these machines, cost is not just the FOB price. You must add freight, insurance, and import duties. For example, the 5% duty in Nigeria applies to the CIF value (cost, insurance, freight), not just the FOB price. A $16,000 mini might land at $18,000–$20,000 depending on freight rates and destination. A 20–30 tonne machine like the 320DIMPORT will cost significantly more to ship due to its size and weight.
Quality varies with year, hours, and condition grade. The 2025 minis have the lowest hours and the latest designs. The 2022 mini is a close second. The 2011 320DIMPORT is older and has higher hours, but it is priced accordingly. None of these machines are new, and none come with a manufacturer warranty. They are sold as inspected, with the year and hours provided as a reference, not as proof of use.
Lead time depends on your destination and shipping schedule. Anhui Gangya Construction Machinery Co., Ltd. is an independent exporter based in China. We do not represent Caterpillar Inc. or any authorized dealer network. We source used machines and export them directly. Typical lead time from confirmed order to shipment is 7–14 days, plus ocean transit time (which can range from 2 weeks to 6 weeks depending on the port). We provide documentation for Chinese customs export regulations and can assist with the paperwork.
Who Should Pick What
-
Choose the CAT 306E2 if you need a low-cost mini for light utility work and you are comfortable with a 2022 machine that has 800 hours. It is the most affordable way to get into a used CAT mini.
-
Choose the CAT 307E2 if you want a nearly new mini with only 500 hours and a 2025 build year, but you do not need the extra features of the 307.5. It is the best balance of price and freshness in the mini range.
-
Choose the CAT 307.5 if your work demands the latest mini design with tight-access capability and you are willing to pay a premium for it. This is the top-of-the-line mini in our current stock.
-
Choose the CAT 320DIMPORT if you need a larger machine for heavy digging and you are on a tight budget. The $15,000 FOB price is low for a 20–30 tonne excavator, but factor in higher shipping costs and the older age. It is a good fit for contractors who can handle maintenance and want a capable workhorse.
