FAQ

Q: What is the standard lead time from order confirmation to port delivery?

A: Standard inspection and export prep require 10 to 15 business days. Custom modifications (such as RHD conversion or hydraulic PTO installation) require 20 to 25 business days. Port delivery takes an additional 5 to 7 days.

Q: How do you verify the true operating history and performance of a HOWO truck?

A: We connect directly to the engine ECU to pull historical fault codes, operating hours, and performance statistics. Every buyer receives an inspection sheet, oil analysis data, and an HD video report showing cold engine startup and brake testing.

Q: Are genuine Sinotruk spare parts easily accessible after purchase?

A: Yes. We stock fast-moving maintenance items (filters, brake shoes, clutch discs, sensors, and belts) and can pack a dedicated spare parts kit inside the cabin during shipment upon request.

Q: Can we appoint an independent third-party inspection agency before final payment?

A: Yes. We welcome inspections from international testing bodies such as SGS, Bureau Veritas (BV), or TUV at our facility before the final balance payment is released.

Q: What emission standards are available, and how do you handle high-sulfur diesel regions?

A: Our inventory includes Euro II, III, IV, and V compliant models. For destinations with high-sulfur fuel, we provide technical adjustments and ECU calibration to ensure reliable operation without filter clogging.

Q: What payment terms and trade clauses do you support?

A: We trade under FOB, CFR, and CIF Incoterms 2020. Standard terms require a 30% T/T deposit upon contract execution, with the 70% balance paid after final factory inspection and prior to vessel loading (or via sight Irrevocable L/C for qualified fleet orders).
