Used CAT excavators rank as the most frequently purchased brand among B2B buyers. Caterpillar holds approximately 18% of the global excavator market share, with its three flagship models—the 320D, 330D and 336—consistently leading circulation volumes in the used machinery market. Nevertheless, there is a massive performance gap between suppliers of pre-owned CAT excavators: factory-backed official CAT certified units come with manufacturer warranties, machines certified under JUMVEA/JEVIC carry verified Japanese maintenance records, and auction platforms offer the widest selection yet require buyers to conduct independent equipment inspections.
We have conducted in-depth evaluations of seven mainstream used CAT excavator suppliers across four core metrics: certification systems, inventory scale, sourcing channels and export experience, to help you identify genuinely reliable partners.
Our evaluation data is sourced from each supplier’s official websites, Caterpillar’s official certification program, transaction records from Japanese auction platforms, and authentic feedback from B2B buyers. We will first present a quick overview comparison of the seven suppliers, followed by a detailed breakdown of each one’s respective strengths.

1.Cat Certified Used
Cat Certified Used is the most trustworthy source of Used CAT Excavator, coming straight from Caterpillar’s official certification system. Every machine goes through over 140 inspection items by authorized CAT dealers, covering five major modules: engine, hydraulic system, electrical components, structural parts and safety system.
Machines that pass inspection are awarded the Cat Certified Used label, equipped with warranty service from CAT authorized dealers, genuine CAT parts supply guarantee and full after-sales support from local CAT agents. CAT’s dealer network covers more than 160 countries globally. No matter your location, local CAT dealers can arrange delivery and after-sales service — an edge no other Used CAT Excavator supplier can match.
Core Advantages
- Official CAT certification with 140+ inspection standards: Inspected under factory criteria instead of third-party testing
- CAT dealer warranty + genuine CAT parts commitment: The most robust after-sales protection for Used CAT Excavator
- Global dealer network across 160+ countries: Local delivery and aftercare, no self-arranged international logistics required
Points to Note
- Prices carry a 15–25% premium against unofficial channels due to official certification costs
- Inventory only includes second-hand machinery owned by respective dealers, with fewer options than auction platforms
- Stock varies widely between regions; some areas have limited models of Used CAT Excavator
Core Merit: Official CAT certification, dealer-provided warranty and global after-sales service. Perfect for buyers who demand maximum certification credibility and comprehensive after-sales coverage for Used CAT Excavator.
2.UsedExcavatorsForSales
Among seven suppliers of Used CAT Excavators, UsedExcavatorsForSales stands out with the most distinctive differentiation — it is the only supplier offering certified imported machinery sourced from three origins: Japan, South Korea and Europe.
Japanese CAT 320D/330D units come with JUMVEA/JEVIC certifications, complete maintenance records and low operating hours. South Korean CAT models are priced 10–15% lower than equivalent Japanese units. European CAT excavators comply with CE standards and Euro V emission regulations. Direct supply from these three origins allows you to source the optimal Used CAT Excavator tailored to your project requirements.
Every machine is accompanied by a full inspection certification report covering six categories: structure, undercarriage, engine, hydraulics, electrics and documentation. Global B2B shipping and packaging services are also provided, delivering a one-stop solution covering customs clearance through final delivery.
Detailed Advantages
- Exclusive certified inventory from three import origins: Japan (JUMVEA/JEVIC certified), South Korea and Europe, delivering far more consistent machine condition than single-source suppliers.
- Full inspection certification for every unit: Comprehensive inspection reports across six categories, so buyers have full visibility into all machine conditions prior to payment.
- Global B2B shipping & packaging service: End-to-end support for customs clearance, transportation and delivery, eliminating the need for buyers to arrange logistics independently.
Core Metrics
- CAT Model Coverage: Focused deeply on three mainstream models — 320D, 330D and 336
- Certification System: Dual JUMVEA + JEVIC certifications available with standardized condition grading
- Sourcing Differentiation: Japanese stock boasts the most consistent machine condition; South Korean stock delivers superior cost performance; European stock offers top-tier regulatory compliance
Core Strength: Full inspection certification, three-origin imported inventory and global B2B shipping support — the sole supplier of Used CAT Excavators that fulfills all three capabilities simultaneously.
3.Ritchie Bros
Ritchie Bros. is the world’s largest heavy equipment auction platform, auctioning hundreds of thousands of machines every year. Used CAT Excavators rank among its highest-volume product lines. Auction listings feature nearly every CAT model, ranging from the 320D to the 336, as well as mini units up to large-tonnage excavators. It operates simultaneous online and on-site auctions across over 40 auction yards worldwide, supporting settlements in multiple currencies including USD, EUR and CAD. The standout merit of the auction model lies in its vast selection: a single auction may host over 50 Used CAT Excavators up for bidding at the same time, far exceeding the stock of any individual supplier. However, auctions follow an “as-is, where-is” policy with no certified inspections or warranty coverage, placing full inspection responsibility on buyers.
Detailed Advantages
- Unmatched global inventory selection: Over 50 Used CAT Excavators available for bidding per auction with the broadest model coverage
- 67 years of auction expertise: Streamlined, proven processes with more than 40 global auction yards and dual online/offline bidding channels
- Multi-currency settlement plus international logistics coordination: Lowest entry barrier for buyers worldwide
Key Considerations
- Strict “as-is, where-is” auction terms: No certified machine inspections or warranty provided; buyers bear full inspection liability
- Unpredictable pricing via competitive bidding: Popular models may carry a 10–20% price premium
- Buyers must inspect machines personally or hire third-party inspectors, incurring extra costs of $500–$2,000 per unit
Core Strength: The widest global equipment selection paired with well-established auction procedures. Ideal for buyers seeking maximum inventory variety, comfortable with auction workflows, and capable of conducting independent machine inspections.
4.TOKU WORLD
TOKU WORLD holds the largest inventory of Used CAT Excavators sourced from Japan, stocking more than 1,477 heavy-duty machines. Mainstream models including CAT 320D, 320E and 330D are consistently available in ready stock.
Central Japan (Nagoya) serves as Japan’s core trading hub for construction machinery, home to two major auction yards: USS and AUCNET. Thanks to its prime geographic location, TOKU WORLD secures newly auctioned inventory faster than competitors.
Japanese Used CAT Excavators boast some of the best maintenance standards globally. Local rental firms follow strict service schedules, and unit operating hours are generally lower than identical models sold in Southeast Asia and Africa. However, it only supplies Japanese-sourced machinery, with no coverage for Korean or European equipment.
Detailed Advantages
- Inventory of over 1,477 units: Largest stock of ready Used CAT Excavators in Japan with ultra-fast order response
- Strategic Nagoya location: Proximity to USS and AUCNET auction yards enables priority access to the latest auction stock
- Sourced from Japanese rental companies: Complete maintenance records, low working hours and highly consistent machine condition
Important Considerations
- Only Japanese stock available; Korean and European CAT excavators are not offered
- Machine inspection standards are less standardized compared to the JUMVEA/JEVIC certification systems
- Wide general machinery brand coverage, yet less specialized focus on CAT units than dedicated import suppliers
Core Strength: Largest Japanese inventory and fastest availability of ready machines. Ideal for buyers requiring in-stock Japanese Used CAT Excavators with quick delivery.
5.Export Fujisawa
Fujisawa Trading (Export Fujisawa Trading) is the only supplier of Used CAT Excavators that integrates refurbishment repair and export services, covering the full range from mini 307D excavators up to large 336 models.
Founded in 1999 with 27 years of export experience, it operates its own repair factory in Kanagawa, offering comprehensive services across seven major repair categories: engine overhaul, hydraulic cylinder restoration, radiator maintenance, swing gear inspection & repair, track refurbishment, frame restoration, and electrical system troubleshooting.
This allows buyers to purchase professionally refurbished Used CAT Excavators instead of machines sold on an “as-is” basis. However, repair and refurbishment require an additional lead time of typically 2–4 weeks, resulting in longer delivery schedules compared to ready-stock exports.
Detailed Advantages
- All-in-one repair and export service: Full coverage of seven core repair categories, supplying professionally refurbished Used CAT Excavators
- 27 years of export experience (established 1999): One of the most seasoned players in the industry
- Dedicated inventory page for CAT machines: Clear display of all model specifications for a smoother shopping experience versus mixed-machinery suppliers
Important Considerations
- Refurbishment adds a 2–4 week turnaround period, extending delivery time relative to ready-stock exports
- Only Japanese-sourced equipment available; no Korean or European Used CAT Excavators offered
- Smaller overall inventory volume than TOKU WORLD’s 1,477+ units, resulting in a relatively limited selection
Core Strength: Integrated refurbishment repair and export service. Ideal for buyers seeking professionally reconditioned machinery and willing to wait 2–4 weeks for better-condition Used CAT Excavators.
6.TS Export
TS Export provides the most budget-friendly Japanese-sourced Used CAT Excavators. It procures machines directly from Japanese auction venues including USS and AUCNET, cutting out markup costs from middlemen. Its official website hosts a dedicated Caterpillar excavator page featuring mainstream models such as the 320D, 330D and 336.
This direct auction sourcing model unlocks original market prices from Japan, which are normally 5–10% cheaper than equivalent Used CAT Excavators purchased through intermediaries. However, buyers must fully rely on grading reports released by auction yards for equipment inspection, which are less detailed than JUMVEA/JEVIC certifications. All machines are sold on an “as-is” basis with no refurbishment or warranty services included.
Detailed Advantages
- Direct auction sourcing at original prices: 5–10% lower than middleman channels, the optimal choice for cost control
- Exclusive CAT page: Centralized display of model specs and auction data for hassle-free selection
- Direct access to Japanese auctions: Real-time updates on the latest USS and AUCNET inventory
Points to Note
- Limited inspection data from auction reports, less comprehensive than the JUMVEA/JEVIC certification system
- All equipment sold “as-is”: No refurbishment or warranty services available
- Only Japanese stock supplied; Korean and European Used CAT Excavators are not covered
Core Strength: Lowest original prices via direct auction procurement. Suitable for budget-first buyers who are familiar with Japanese auction systems and capable of conducting independent equipment inspections.
7.Iron & Earth
Iron & Earth is the top European supplier of Used CAT Excavators tailored for B2B buyers. As a UK-based vendor, it delivers fully transparent, seamless English communication with thorough, complete machine documentation. Its official website features a dedicated “Used Excavators” category page with over 16 excavators listed year-round, covering all Used CAT Excavator sizes from mini units up to 30-ton class models.
The biggest merit of European Used CAT Excavators lies in regulatory compliance: all units hold CE certification and meet Euro V emission standards. Importers based in the Middle East and Africa experience far smoother customs clearance when importing European machinery compared to Japanese units. The UK’s transparent credit framework allows full public verification of the supplier’s company registration and business records via Companies House, enabling buyers to validate vendor credibility. On the downside, its inventory size is limited to 16+ units, offering a narrower selection than Japanese suppliers and auction platforms.
Detailed Advantages
- CE certified & Euro V compliant: European Used CAT Excavators boast the highest regulatory compliance and simpler customs clearance procedures
- Fully transparent English communication: Comprehensive machine data and barrier-free dialogue to minimize transaction risks
- Transparent UK corporate credit system: Company registration details are publicly accessible through Companies House
Important Considerations
- Limited inventory of 16+ units, with fewer model options than Japanese suppliers and auction platforms
- Only UK/European-sourced machinery available; Japanese and Korean Used CAT Excavators are not supplied
- Pricing is 10–20% higher than equivalent Japanese models due to elevated operational costs in Europe
Core Strength: CE regulatory compliance paired with fully transparent English communication. Ideal for buyers requiring Europe-compliant machinery and prioritizing clear, open communication throughout transactions.
Summary
After comprehensive evaluations of seven suppliers of Used CAT Excavators, the conclusion is clear: choosing the right supplier matters more than picking the right model. A reliable supplier screens equipment, provides official certifications, arranges logistics and offers after-sales support, delivering a hassle-free full-cycle experience once you make the right pick. By contrast, partnering with an unsuitable supplier could turn even a CAT 320D into a costly mistake.
