After-Sales Service & Returns Policy

Jianming Machinery supplies diesel engines, machinery parts, hydraulic components, engine overhaul kits and related replacement parts for professional buyers. Because machinery parts must match the exact model, part number and application, please confirm compatibility with our team before placing an order.

Before You Order

  • Please provide the machine brand/model, engine model, part number, nameplate photos or clear photos of the old part when possible.
  • Our team can help check compatibility, but final confirmation should be based on the actual machine and part information provided by the buyer.
  • Custom, special-order, used or installed parts may not be eligible for return unless there is a confirmed quality issue or shipment error.

Order Problems We Can Help With

  • Wrong item shipped by us.
  • Missing items or quantity discrepancy.
  • Visible transport damage reported with photos/videos soon after delivery.
  • Confirmed manufacturing or quality defect before installation or during reasonable inspection.

Return Conditions

  • Please contact us before returning any item. Returns without prior confirmation may not be accepted.
  • Returned parts should be unused, uninstalled, clean, complete and in original packaging where possible.
  • Electrical parts, customized parts, special-order parts, installed parts, parts damaged by misuse and parts returned because of incorrect buyer information may not be returnable.
  • If the issue is caused by our shipment error or a confirmed product quality problem, we will work with you on replacement, repair, credit or refund depending on the case.

Non-Quality Returns

For non-quality reasons such as ordering the wrong model, compatibility mismatch caused by incomplete information, or order cancellation after dispatch, return approval depends on the product condition and supplier/manufacturer policy. Shipping costs, customs duties, taxes, bank charges and restocking costs may be borne by the buyer.

Inspection After Delivery

Please inspect all parts as soon as possible after delivery. If there is damage, missing quantity or a wrong item, please contact us with photos, videos, package labels and order information so we can investigate quickly.

Warranty / Quality Support

Warranty handling depends on the product category, brand, supplier policy and actual usage condition. Damage caused by incorrect installation, improper use, lack of maintenance, modification, contamination, overheating or external impact is not covered.
