When buying a used excavator from an independent exporter like Anhui Gangya Construction Machinery Co., Ltd., you need a clear, repeatable inspection process and a condition grade you can trust. This guide outlines seven steps that international buyers can use to evaluate machines, with real examples from CAT Excavator Export inventory. We focus on facts: model, year, hours, condition grade, and FOB price. No fluff, no vague claims. Whether you are a contractor in Nigeria or a dealer in Latin America, these procedures help you avoid costly surprises.
1. Verify the Machine's Identity and Paperwork
Best for: Buyers who need to confirm the machine matches the listing.
Why it stands out: Mismatched serial numbers or missing documents can cause customs delays and legal issues.
Start by checking the machine's data plate and serial number against the export documents. The HS code for excavators is typically 8429.52, and Chinese customs export regulations require accurate declaration. For example, a 2022 CAT 305.5 / 305.5E2 mini excavator under 10 t, with 800 hours, listed at $16,000 FOB, should have a serial number that matches the invoice and bill of lading. Cross-reference the year and hours with the inspection report. Remember, year and hours are given as a reference, not as proof of use. If the seller cannot provide a start-up video and photos of the actual unit, walk away. Anhui Gangya provides these for every machine, including a 2011 CAT 320DIMPORT with 8,000 hours, Grade B, at $15,000 FOB.
2. Inspect the Undercarriage and Ground Engagement Tools
Best for: Buyers of 20-30 t class excavators used in heavy digging.
Why it stands out: Undercarriage wear is the most expensive repair item and directly affects the machine's value.
Check track tension, sprocket wear, idler condition, and track shoe thickness. For a 2011 CAT 320DIMPORT (20-30 t class, 8,000 hours, Grade B), expect noticeable wear. Measure the track shoe height; if it is below 50% of new, plan for replacement. Also inspect the bucket teeth and cutting edge. A 2025 CAT 307.5 mini excavator with only 500 hours, priced at $26,000 FOB, should have minimal undercarriage wear. Take photos of each component. If the seller's inspection report does not include undercarriage measurements, ask for them. This step alone can save you thousands in parts and labor.
3. Evaluate the Engine and Hydraulic Systems
Best for: All buyers, especially those purchasing high-hour machines.
Why it stands out: Engine and hydraulic repairs are the most costly and can sideline a machine for weeks.
Start the engine from cold and listen for unusual noises. Check for blow-by by removing the oil filler cap. Inspect for leaks around the hydraulic pump, cylinders, and hoses. For a 2022 CAT 305.5 / 305.5E2 with 800 hours at $16,000 FOB, the engine should start quickly and run smoothly. For the 2011 CAT 320DIMPORT with 8,000 hours, expect some seepage but not active leaks. Ask for a hydraulic oil sample analysis if available. A start-up video can show you how the machine idles, revs, and operates. If the seller does not provide a video, request one. Anhui Gangya includes a start-up video for every unit, including the 2025 CAT 307.5 and the 2011 CAT 320DIMPORT.
4. Check the Cab, Controls, and Safety Features
Best for: Buyers who will operate the machine daily or rent it out.
Why it stands out: A damaged cab or faulty controls can lead to operator fatigue and safety risks.
Inspect the cab for rust, cracks, and missing glass. Test all controls: joysticks, pedals, and switches. Ensure the seat belt, mirrors, and lights work. For a 2025 CAT 307.5 with 500 hours at $26,000 FOB, the cab should be nearly new. For a 2011 CAT 320DIMPORT, expect wear on the seat and some play in the joysticks. Check the monitor for error codes. If the machine has a Grade B rating, some cosmetic issues are acceptable, but safety features must function. Anhui Gangya's inspection reports include cab condition and control functionality. Always ask for photos of the cab interior.
5. Understand the Condition Grading System
Best for: Buyers comparing multiple machines across different price points.
Why it stands out: A consistent grading system helps you compare apples to apples.
At CAT Excavator Export, we use grades like "as inspected" and "Grade B." "As inspected" means the machine is sold in the condition observed during inspection, with no hidden guarantees. For example, a 2022 CAT 305.5 / 305.5E2 with 800 hours at $16,000 FOB is rated "as inspected." Grade B indicates a used machine with normal wear but no major defects. The 2011 CAT 320DIMPORT with 8,000 hours at $15,000 FOB is Grade B. These grades are not standardized across the industry, so always ask for the specific inspection report. The report should detail undercarriage, engine, hydraulics, and cab. Use the grade as a starting point, not the final word.
6. Request a Start-Up Video and Inspection Report
Best for: Remote buyers who cannot inspect the machine in person.
Why it stands out: Video and reports provide verifiable evidence of condition before you commit.
A start-up video should show the machine starting from cold, idling, revving, and operating each function. The inspection report should list measurements and observations. For a 2025 CAT 307.5 with 500 hours at $26,000 FOB, the video should show a smooth start and no smoke. For a 2011 CAT 320DIMPORT with 8,000 hours at $15,000 FOB, expect some smoke on start-up but it should clear. Anhui Gangya provides these for every unit. If a seller refuses to share a video or report, consider it a red flag. The cost of a video is minimal compared to the risk of buying a lemon.
7. Factor in Shipping, Customs, and Final Costs
Best for: Buyers who need a total landed cost, not just the FOB price.
Why it stands out: FOB price is only part of the equation; duties and freight can add 20-30%.
For Nigeria, the HS code 8429.52 may attract a duty of 5% and VAT of 7.5%. For a $15,000 FOB machine, that adds roughly $1,875 in taxes, plus freight and insurance. Always ask for a breakdown. Anhui Gangya can provide estimates based on destination. For a 2022 CAT 305.5 / 305.5E2 at $16,000 FOB, the total landed cost in Lagos might be around $20,000. For a 2025 CAT 307.5 at $26,000 FOB, expect higher freight due to size. Use international shipping and freight resources to verify rates. Remember, Chinese customs export regulations require accurate value declaration, so do not under-invoice.
8. Compare Real Listings to Calibrate Your Expectations
Best for: Buyers who want to see how hours and year affect price.
Why it stands out: Real examples from inventory show the relationship between condition, hours, and FOB price.
Consider these three units from CAT Excavator Export: - 2022 CAT 305.5 / 305.5E2: 800 hours, "as inspected," $16,000 FOB. Mini class under 10 t. - 2025 CAT 307.5: 500 hours, "as inspected," $26,000 FOB. Mini class under 10 t. - 2011 CAT 320DIMPORT: 8,000 hours, Grade B, $15,000 FOB. 20-30 t class. Notice that the 2025 mini is priced higher than the 2011 larger machine. Why? Lower hours, newer year, and smaller size can command a premium in some markets. The 2011 machine is cheaper but has higher hours and a lower grade. Use these data points to negotiate. If a seller offers a similar machine at a much lower price, ask why. There may be hidden issues. Anhui Gangya lists each unit individually, so you can compare directly.
9. Document Everything and Get It in Writing
Best for: All buyers, especially first-time importers.
Why it stands out: A written record protects you if the machine arrives in different condition.
Before payment, ensure the sales contract includes the machine's model, serial number, year, hours, condition grade, FOB price, and included accessories. For a 2022 CAT 305.5 / 305.5E2 at $16,000 FOB, the contract should state "as inspected" and reference the inspection report. For a 2011 CAT 320DIMPORT at $15,000 FOB, include "Grade B" and note any known defects. Also specify the HS code (8429.52) and Incoterms (FOB). If the seller provides a start-up video, reference it in the contract. Anhui Gangya provides a written inspection report for each unit. Keep copies of all documents for customs clearance.
10. Make Your Decision Based on Facts, Not Pressure
Best for: Buyers who want to avoid impulse purchases.
Why it stands out: A disciplined approach ensures you get the right machine at the right price.
After reviewing the inspection report, video, and total cost, compare the machine to your project needs. For utility work in tight spaces, a 2025 CAT 307.5 at $26,000 FOB might be ideal. For heavy digging, a 2011 CAT 320DIMPORT at $15,000 FOB could work if you can handle the higher hours. Do not let a salesperson rush you. Anhui Gangya is an independent exporter and does not imply affiliation with any manufacturer. We provide facts so you can decide. If a machine does not meet your needs, wait for the next one. There is always another unit coming.
