When a deck or boardwalk must survive decades of heavy use, the shortlist usually narrows to a few very dense tropical hardwoods. Ipe from South America has long been the best-known name, but tali from Central Africa has become one of the most popular alternatives, especially since ipe was listed on CITES Appendix II. Councils, marinas, landscape architects and deck builders now regularly compare tali vs ipe on performance, supply and cost. Both are excellent timbers; the right choice depends on your project, budget and how much paperwork and lead time you can accept.
In this guide we compare the two on density, hardness, wear, durability, stability and checking, appearance, weight and installation, legal status, supply and cost. At Global Timber Trade Hub we supply tali from Cameroon, Gabon and the Republic of Congo; we do not sell ipe, but we have aimed to describe it fairly.
In short
- Ipe is harder and heavier; tali is very dense and durable but a little less hard.
- Both are proven on heavy-use decks, boardwalks and marine structures.
- Tali is warm reddish-brown; ipe is olive to dark brown.
- Both can check in hot, dry conditions; kiln-dried stock and early oiling help.
- Ipe needs CITES permits; tali does not.
- Tali usually has a lower total project cost and steadier supply.

Density, hardness and wear
Ipe is among the hardest commercial woods in the world, and its resistance to abrasion and denting is outstanding. Tali is also very dense, close to the 1,000 kg per cubic metre mark, and very hard, though somewhat below ipe. In practice, on most public decks, marinas and boardwalks, tali’s wear resistance is more than sufficient, and its grooves and profiles stay crisp for many years. Ipe’s extra hardness becomes a deciding factor mainly on the very busiest promenades and service routes with constant wheeled traffic.
Durability
Both species are very durable against fungi and insects, in ground contact and around water. Ipe has a long international record on boardwalks and decks. Tali has a long record in Europe and Africa for railway sleepers, bridges, marine works and decking. With good design and ventilation, both should last for decades.
Stability and checking
Like most very dense hardwoods, both can develop surface checks and end splits as they dry and weather, particularly in strong sun and dry wind. Ipe is well known for this, and end sealing is standard practice. Tali behaves similarly but is often slightly easier to manage in board sizes. To reduce checking with either species, buy kiln-dried decking, seal cut ends immediately, store boards covered before installation, oil early and avoid very wide boards in harsh climates.
Appearance
Tali ranges from yellow-brown to reddish-brown when new, with natural colour variation, and quickly evens out to a warm reddish-brown before weathering to silver-grey. Ipe is darker, olive to chocolate brown, weathering to a deeper grey. Tali gives a warmer, lighter deck; ipe a darker, more uniform one. In very hot sun, darker ipe tends to get hotter underfoot.
Weight and installation
Ipe is heavier than tali, which affects handling on site, structural loads and freight. Both need carbide tooling, pre-drilling of every fixing and stainless screws or hidden clips. Tali is somewhat easier to cut, drill and profile, which can shorten installation time on large projects. See our tali decking guide.
CITES and supply
Ipe (Handroanthus and related genera) was listed on CITES Appendix II, with the listing taking effect in late 2024, so every commercial export needs a CITES permit and supply has become less predictable. Tali is not CITES listed. It still requires full legal origin documents for EU, UK and US imports, but it avoids permit delays and the risk of shipments held for permit issues. For public projects with tight programmes, that can be decisive. See our CITES timber species guide.
Total project cost
Kiln-dried tali decking starts from about $850 per m³ FOB, around $19–24 per m² in board value for 21 mm boards. Ipe prices vary but are generally higher. Add ipe’s greater weight, which raises freight per square metre, and its longer installation time, and the total cost gap usually widens further. See our tali wood price and hardwood decking cost guides.
Best uses for tali
- Park boardwalks, nature reserve paths and pontoons.
- Residential and commercial decks.
- Railway sleepers and bridge decks.
- Marine and riverbank works.
Best uses for ipe
- Extremely busy promenades and service routes.
- Projects specifying ipe for a uniform dark look.
- Marine structures where maximum hardness is required.
A worked example for a marina
Consider a marina replacing its main walkways and visitor pontoon decks, about 800 square metres in total. The original tender specified ipe, but the shortlisted suppliers could not guarantee delivery dates because of CITES permit timing, and the prices had moved since the budget was set. The marina’s engineer reviewed the performance data and accepted tali as an alternative, specifying 32 × 145 mm grooved kiln-dried boards with sealed ends, fixed with marine-grade stainless screws over hardwood bearers. The tali arrived in three containers on the agreed schedule, with legal origin documents for the procurement file and no permit delays. Installation was a little faster than the contractor expected for an ipe job, and the warm reddish-brown colour weathered to an even grey within the first year. The marina now specifies tali for its rolling programme of pontoon replacement, with deck boards cut to a standard length so spares are easy to stock.
Specifying tali in tenders
If your organisation has always specified ipe, update the specification to allow equivalent species on performance rather than by name. State the required durability, density range, profile, grade, moisture content and documentation, and include tali, okan and other suitable species as accepted alternatives. This opens the tender to more suppliers, reduces risk of delay and often lowers cost. Our okan decking guide covers another strong option.
Lead times and payment
Kiln-dried tali decking is usually ready to load in 6–10 weeks. For first orders, a letter of credit or a deposit with balance against copy documents protects both sides. See our letter of credit for timber guide.
Slip resistance on heavy-use decks
On public boardwalks and marinas, grip matters as much as durability. Both tali and ipe are dense enough to hold grooves and ribs for many years, so the profile you choose will keep working. For wet, shaded routes, grooved boards laid across the direction of travel, combined with resin-and-grit anti-slip inserts where people turn or walk on slopes, give the best grip. Keep drainage gaps clear of leaves and silt, and schedule cleaning in spring and autumn to remove algae. On residential decks, fine-ribbed or smooth boards are usually enough and more comfortable for bare feet. Whichever species you choose, the profile, drainage and cleaning regime decide how safe the deck is in practice. Ask us for profile drawings if you need to include them in a specification, and check local guidance for slip resistance on public walkways. See our best wood for bridges guide for related design advice.
Sustainability and documentation
Both species come from natural tropical forests. Ipe exports need CITES permits; tali needs legal origin documents and, for many public projects, certification. EU buyers must meet the deforestation regulation for both. Ask for documents at the quote stage and keep them on file. See our EUDR timber compliance guide.
Weight and freight
Both species are heavy, so containers fill by weight before volume. A 20 ft container usually carries around 18–22 m³ of tali decking, and less of ipe because of its higher density. That means freight per square metre of finished deck is lower for tali on the same route. On large projects, this difference adds up to a meaningful saving. Mixing tali with lighter species, or using 40 ft containers where road weight limits allow, can improve loading further. See our timber shipping cost guide.
Ordering tali decking
When you send an enquiry, tell us the board thickness and width, profile, total area or volume, any fixed lengths, whether you need bearers, joists or kerbs, and your destination port. For public projects, include the specification and documentation requirements, so we can confirm compliance before you award the contract. We can also supply sample boards for approval.
Spare boards from the same parcel make future repairs easy to match.
Store them dry and flat.
Common mistakes
- Specifying ipe by habit: tali often meets the same need with simpler supply.
- Not sealing ends: both species can split at the ends.
- No pre-drilling: screws snap in dense wood.
- Ignoring weight: both are heavy; plan handling and loads.
Our honest advice
For most heavy-use decks and boardwalks, tali delivers very similar real-world performance to ipe at a lower total cost, without CITES paperwork. Choose ipe only where its extra hardness is truly needed and legal supply is secure. Whichever you choose, use kiln-dried boards, seal ends, ventilate well and install with proper tooling.
