Parts for trailers and semi-trailers in Hong Kong

The price of a trailer part depends on the part, but the listings we found for November 2026 show complete trailers: a 3-axle flatbed starts at about HK$46,100 and a heavy-duty 80-tonne unit reaches about HK$149,100. These are approximate figures from sellers' websites. For a part's price, post a free request on BlaBlaPrice with the part and the trailer details.

Rules that apply to trailers

The construction and maintenance rules for vehicles in Hong Kong (Cap. 374A) cover semi-trailers whose permitted gross weight is above 2 tonnes, including the spacing of their axles. Before you order a part, check that it suits your trailer's weight class and axle layout. Cargo must also be restrained properly: the Transport Department's Code of Practice for the Loading of Vehicles covers general freight and mixed loads, so a damaged tie-down or floor part is worth fixing first.

Planning around the seasons

Hong Kong summers run from June to August and are hot, so brake, tyre and lighting work is better scheduled before June. The winter months, December to February, are milder and suit a full service. Order parts before you need them, so the trailer does not stand idle while waiting for delivery.

How prices are quoted here

Listings show each trailer in HK$ per unit and rarely include delivery, so ask whether the price includes delivery to your city: Central, Kowloon, Sha Tin, Tsuen Wan or Tuen Mun. Specifications are given in tonnes, axles and metres of deck length, so compare those, not only the price. Some listings come from overseas manufacturers, so confirm shipping and import costs.

What to put in your request

Name the part you need, the trailer type and model, its year, and the part number if you have it. Say whether you want an original or a compatible part, its condition (new or used), and the axle count and load in tonnes. Add the delivery city and your budget in HK$.

Describe the part in your own words on BlaBlaPrice and add a photo of the worn piece if you have one. The AI reads the request, asks for missing details and looks through sellers' websites and price lists in Hong Kong before it shows the prices and businesses it found. Sellers registered on BlaBlaPrice reply in the chat with their own offer and delivery terms, and your contacts stay hidden until you choose whom to contact. You can also browse truck parts or commercial vehicle and machinery parts.

Questions and answers

How much does a semi-trailer cost in Hong Kong?

On sellers' websites in November 2026, complete trailers were listed from about HK$46,100 for a 3-axle flatbed to about HK$149,100 for an 80-tonne heavy-duty unit. These are whole trailers, not parts, so ask for a quote on the specific part you need.

Are there rules for trailers over 2 tonnes?

Yes. The Cap. 374A rules on vehicle construction and maintenance cover semi-trailers whose permitted gross weight is above 2 tonnes, including axle spacing.

Do I need the part number to order?

It is not always required, but it speeds up the quote. Give the trailer model and year as well, so the seller can check that the part fits.
