Used Motor Grader Prices and DDP Thailand Import Guide: XCMG GR180 and Cat 140H Reference Bands with Inspection Points (2026)

The short answer first: in China's 2026 used grader market, reference bands by brand tier are roughly — mainstream domestic units (XCMG GR165/GR180, ~180 hp class, moldboard ~3.7–4.0 m, operating weight 15–16 t; Tiangong PY180 and LiuGong CLG418 in the same class) at RMB 50,000–150,000; imported Caterpillar 140H/140K/140M units (165 hp class, 2013–2023, 1,000–3,500 h) at RMB 130,000–220,000; Komatsu GD675/GD825 sit in the Cat band. Delivered DDP to Bangkok adds about 15–25% over the ex-works price, covering ro-ro or flat-rack freight, insurance, clearance, and 7% VAT. These are market reference bands; the binding figure is the quote for a specific inspected unit.

Why graders suit Thai buyers: Thailand's road construction and maintenance demand is steady, and the grader completes the road-machinery trio alongside rollers and pavers — our 2026 used-road-roller reference article already covers the compaction stage, while the grader handles fine-grading of the base course, a common fleet addition for local contractors. Structurally, a grader is a wheeled, self-propelled machine — unlike tracked equipment it is not a freight hog: at 15–16 t it can drive on and off ro-ro vessels, and parts are well supplied in Thailand (Cummins/Weichai engines, ZF or Hangzhou gearboxes). It imports under HS 8429.20, an ITA product with 0% duty and 7% VAT.

Shipping: three common options — ro-ro (the machine drives on and off; freight-friendly; about 7–12 days from South China to Bangkok), 40-foot flat rack (moldboard removed or folded, useful where destination ro-ro facilities are limited), and break-bulk for batch shipments of several units. For three units or more, combining ro-ro with break-bulk pushes per-unit freight down noticeably. Before shipment: drop the fuel to a safe level, secure the moldboard and circle, disconnect the battery, and take 360-degree photos plus nameplate shots.

Import compliance: Thailand imposes no age ban on used construction machinery; clearance documents are invoice, packing list, bill of lading, nameplate-year photos, and a depreciation note. Customs reviews depreciation-adjusted valuation for used equipment — an unrealistically low declaration gets adjusted upward, so declare honestly with the original invoice attached. BOI-promoted companies can apply for duty exemption on machinery within the approved list, but used equipment must be listed in advance — whether a grader qualifies depends on the promoted activity, so confirm with BOI against your project.

Inspection checklist (grader specific): one, the circle — excessive circle play is the costliest hidden repair on a grader; rotate the moldboard left and right on site to feel the slack; two, the moldboard system — blade-face wear, cutting-edge replacement history, side-shift and tilt-cylinder leaks; three, the drivetrain — run every gear, checking the powershift transmission for smooth shifts and noise; four, articulation and rear axle — a turn test to check articulation play; five, engine and hydraulics — cold-start smoke, raise/tilt speeds, ripper function; six, tires — six tires carry a meaningful share of total value, and uneven wear hints at frame or rear-axle trouble. Pay 30% deposit and 70% after a passed on-site test.

Bottom line: graders are the 'stable value' category in used road machinery — a usable domestic unit lands at around RMB 100k and a Cat at RMB 150k, with a DDP uplift near 20%. Guard the two big wear items — the circle and the moldboard — and you will not step into a pit.
