Sourcing wooden barrel saunas from China

Duty is low, freight is not

A barrel sauna or sauna cabin made of wood is, for tariff purposes, usually a prefabricated building of wood. Read from the UK Trade Tariff on 25 September 2026, that code carries 2% duty on goods from China, and so do the stove and an electric sauna heater, with no anti-dumping measure on any of them. A kit sent as loose boards rather than a building may be classed differently, so confirm the commodity code for what is actually in the crate. For cold-room buildings, see our walk-in cold-room sourcing guide. For garden storage buildings, see our metal garden shed sourcing guide.

Duty is rarely what decides the landed price of a sauna. Volume is. An assembled barrel sauna ships a great deal of air, and even flat-packed it is a large, heavy consignment for its value, so the freight quote matters as much as the factory price. Our duty calculator and sea versus air calculator put both into one landed figure.

The heater: what the rules cover and what they leave out

The UK ecodesign regulations for heaters, retained from EU law, explicitly exclude sauna stoves: Article 1 of the solid fuel regulation and Article 1 of the regulation for other local space heaters both list sauna stoves among the products they do not apply to. That removes an efficiency and emissions test a wood-burning room heater would face, but it does not remove the duty to supply a safe product, and installing a solid fuel appliance is a building control matter where the sauna is put up. Check with the local authority before the flue is fitted.

An electric sauna heater is electrical equipment under the Electrical Equipment (Safety) Regulations 2016, which apply to equipment designed for 50 to 1,000 volts alternating current. The product standard is IEC 60335-2-53, which covers sauna heating appliances and infrared cabins with a rated power input of up to 20 kilowatts, rated at no more than 250 volts single-phase or 480 volts otherwise. Ask for a test report to that standard naming the exact heater model, not a certificate for the range.

The timber, and what to check in the build

Timber placed on the UK market must not be illegally harvested, and the business placing it on the market has to exercise due diligence to show it is not. The retained EU Timber Regulation lists prefabricated buildings among the timber products it covers. Ask the factory for the species, the country of harvest and the supply chain documents before you order, because they are needed to do that due diligence and they are hard to reconstruct afterwards.

On the build itself, the points that separate a sauna that lasts from one that does not are the fit of the staves or wall boards, the steel bands on a barrel and how they are tensioned, the roof covering, the door glass, and the clearance and heat shielding around the stove and its flue. Put each of those in the specification, photograph the approved sample, and have a pre-shipment inspection check the goods against it before they are crated.

Worked duty example

Suppose, purely for illustration, you import 20 flat-packed barrel saunas under 9406 10 00 00. At £40,000 free on board and £8,000 to ship and insure, the customs value is £48,000. Wooden saunas at 2% pay £960 of duty; VAT is then worked out on value plus duty, £48,960, giving £9,792. Of the £10,752 paid at import, only the £960 of duty stays a cost for a VAT-registered business. Freight is a sixth of the customs value because saunas are bulky even flat-packed. The method is set out in how UK import duty and VAT work.

Inspection checklist

Timber paperwork: prefabricated wooden buildings are listed in the annex to retained Regulation (EU) No 995/2010, so collect species, country of harvest and legality evidence for the cabin timber before shipment.

Metal parts: run neutral salt spray to ISO 9227 on steel bands, hinges and fixings, and check stainless grades and coatings match the specification for outdoor use.

Flue and stove: check chimney and flue parts are designated to BS EN 1856-1 for the flue gas temperature of the stove, and check clearances, heat shields and the rain cap on the dry-fitted sample.

What goes wrong

Saunas fail on timber, joinery and the heater. Staves and boards shrink after the first heat cycles so gaps open and heat escapes, timber arrives too wet or with loose knots that fall out, steel bands corrode, and roof coverings leak. Wood-burning stoves lack the clearances and heat shields the installation needs, flue parts do not fit, and electric heaters arrive without UK plugs or wiring suited to the supply.

Check timber moisture content at packing and look for loose knots and resin pockets, dry-fit a sample sauna to check stave and door fit, check band and fixing corrosion protection, water-test the roof, ask for wood-burning stove tests to EN 15821 and electric heater tests to BS EN 60335-2-53, and check installation clearances, flue parts and electrical connections against the instructions.

One sauna or a container, to the UK or further afield

Because a sauna is bulky and often a one-off purchase, the sensible first order is a single unit, sampled and inspected, and consolidated with other goods if you have them. Cambridge China Bridge adds no minimum of its own, so a one-sauna order is quoted the same way as a container.

Portable fabric saunas with a wood-fired stove are a different product with a different risk profile, set out in our portable sauna guide, which also covers delivery to Jersey and the Channel Islands. Buyers outside the UK receive a price to their own port. See how our sourcing service works.
