What Is the Price of Landscape Gravel per Ton?

There is no single price of landscape gravel per ton, because the tonne is only the unit of sale — what you actually buy is a grade of stone. One 20 ft container carries about 24–27 tonnes of loose landscape gravel, and within that box the price per tonne moves with four factors: the stone family behind the gravel (marble, dolomite or quartz), the width of the size band, whether it is washed, and how it is packed. Ocean freight is charged per container rather than per tonne, so the landed cost per tonne equals material plus packing plus the container rate, all divided by the tonnes actually loaded.

The practical consequence for an importer or merchant is that two quotations both reading 'landscape gravel, FOB China' can differ by 30–50% per tonne and both be correct — because they are prices for two different products measured on two different unit bases. The sequence that makes prices comparable is always the same: fix the grade in millimetres with a sieve analysis, fix the washing status and the packing format, ask for material, packing and freight as separate lines to your named port, and only then compare numbers — ideally after converting everything into cost per square metre of covered surface, which is what the project actually consumes. The rest of this article works through each of those steps.

Why 'Landscape Gravel' Is Not One Product on a Price List

The word 'landscape gravel' covers at least four commercially distinct products, and each carries its own price logic. A 4–10 mm decorative surface grade is screened fine and usually washed, so it carries the highest processing cost per tonne. A 10–20 mm washed single-size grade is the workhorse for decorative beds and drainage and sits in the middle of the range. A 20–40 mm structural or border grade is screened coarser with fewer passes, so it is normally the cheapest per tonne. And a self-binding 0–14 mm graded run with fines — the product used for compacted firm paths — is priced differently again, because the fines that make it compactable must not be washed out.

The stone family underneath adds a second layer. Calcite-family marble gravel is the whitest and usually the cheapest to produce, but it is soft (Mohs 3) and acid-sensitive. Dolomite is slightly harder and similarly priced. Quartz and quartzite gravel is the hardest and most acid-resistant, but it is denser and costs more per tonne. On top of the family, colour drives the yield: an even white or black grade rejects more material during sorting than a mixed tan run, and that reject is paid for by the tonnes that pass. So before comparing any two offers, write down the grade band, the stone family and the colour tolerance — a quotation against those three definitions is comparable; a quotation against the word 'gravel' is a different product every time.

How Do You Convert a Tonne Price into Cost per Square Metre?

Projects are specified in square metres, suppliers sell in tonnes, and the bridge between the two is bulk density — which is why the cheapest per-tonne offer is not always the cheapest installed. Loose landscape gravel runs about 1.4–1.6 tonnes per cubic metre depending on the stone family and the angularity of the grade, so one tonne is roughly 0.65–0.7 cubic metres. Spread at a 30 mm finished depth, that tonne covers about 20–23 square metres; at 50 mm, about 12–14 square metres; at 75 mm, about 8–9 square metres. Compaction raises the effective density by 10–15% on compacted applications, which reduces coverage further, and you should add 5–10% for site loss and levelling unevenness.

Run the conversion on every quote and the ranking often changes. Suppose supplier A quotes a lower price per tonne for a broad graded mix at 1.4 t/m³, while supplier B quotes higher for a washed single-size grade at 1.6 t/m³ — B covers roughly 14% more square metres per tonne at the same depth, which can wipe out the headline gap entirely. A denser stone family does the same thing invisibly. The honest comparison metric is cost per square metre of finished surface at the specified depth: take the landed price per tonne, divide by the coverage that tonne delivers at your project depth, and compare on that number. Every quotation you receive without a stated bulk density is a quotation you cannot convert — so ask for it in the same email that asks for the sieve analysis.

What Does the Container Do to the Price per Tonne?

Landscape gravel is dense enough to reach a 20 ft container's weight limit long before it fills the cube: about 24–27 tonnes loose against roughly 33 cubic metres of internal volume. That single fact shapes the whole price structure. Ocean freight is charged per container, so the freight cost per tonne is simply the container rate divided by the saleable tonnes loaded — and anything that stops you loading tonnes raises your freight per tonne. A 40 ft container is not the better deal for gravel: its payload is only marginally higher under the same weight limits, and destination road rules often cap axle loads further, so the 20 ft box remains the standard economic unit and quotations are built on it.

Packing is the other container-level price decision, and it trades payload against handling. Loose lined loading achieves the highest payload and the lowest packaging cost per tonne; jumbo bags of 1,000–1,200 kg trade a little payload for fast site handling; 20–25 kg retail bags on pallets cost the most payload — typically 10–20% less product in the same box — but they sell the fastest at a merchant counter and command the highest resale margin per tonne. Moisture belongs in the same conversation: free moisture is weight you pay for and product you never see, so specify a moisture maximum with a test report, particularly after a wet-season production run.

Which Factors Move a Landscape Gravel Price Most?

Rank the price drivers in order of impact before you negotiate. First, the stone family and colour tolerance, because they set the reject rate and the yield behind every tonne. Second, the width of the size band: a tight single-size 10–20 mm grade forces extra screening passes and rejects everything outside the band, while a broad graded run sells nearly everything it produces. Third, washing — it adds water handling, drying and another reject stream, which is why a washed grade carries a visible premium over the same stone unscreened of dust. Fourth, packing, which you should choose for the market rather than by reflex. Volume and commercial terms move the price least: they trim the packing and freight lines, not the material line.

Timing matters as much as specification. Gravel prices move with quarry energy costs, with ocean freight rates — which swing far more than the material line on a dense, low-value mineral — and with season: the Chinese New Year shutdown compresses both production and vessel space into the weeks either side, so a quotation issued in December and one issued in March are not the same market. Exchange rate movements pass through on longer lead orders. None of these are reasons to delay a purchase; they are reasons to fix the validity window in writing — 30–60 days is the normal band — and to agree an adjustment cap rather than open-ended renegotiation if you book capacity across the shutdown.

How Do You Compare Two Landscape Gravel Quotes Fairly?

Normalize before you compare, and most fake price gaps disappear. Six things must be identical across both offers: the grade band in millimetres backed by a sieve analysis; the stone family named (marble, dolomite or quartz — the acid-drop test distinguishes calcite from quartz in thirty seconds); the washing status; the packing format with unit-mass tolerance; the Incoterm and named port; and the moisture basis of the tonnage. Then ask both suppliers to split the quotation into material, packing and freight lines — most differences hide in one of the three, and a supplier who will not split it is telling you something. Convert each offer into cost per square metre at your project depth, and rank on that.

Watch the exclusions too. Destination THC, documentation, insurance and inland haulage reappear on the invoice if nobody writes them down, and on a low-value heavy mineral they can add a double-digit percentage to the landed cost. A quotation valid 30 days is a different offer from one valid a week in a moving freight market. Finally, weigh a modest premium for verifiable consistency: a supplier who provides retained sealed samples from each production lot, loading photographs with lot references and third-party pre-shipment inspection rights is selling you a lower risk of a container that cannot be sold — and on repeat containers that risk costs more than the premium.

How Should a First Order Be Priced and Locked?

The commercial floor for exported landscape gravel is one 20 ft container of 24–27 tonnes, and the minimum order quantity should be counted per grade, not per product line: many suppliers will split one container across two or three adjacent grades — say a 10–20 mm washed main line and a 4–10 mm decorative grade — for a small handling premium, which lets a first-time buyer test the market without over-committing. Price breaks concentrate in the packing and freight lines and typically step down in tiers around 1, 3–5 and 10+ containers; ask for the break table in writing rather than assuming a percentage.

Then write the price down so it survives the year. A workable first-order pricing sheet contains: the grade and stone family with sieve analysis; the landed price broken into material, packing and freight lines to your named port; the bulk density used for coverage conversion; the moisture maximum with test method; the price-break table above your volume; the validity window; and, on annual programmes, a base price with a stated adjustment cap tied to published freight indices. Keep a retained sealed sample from the lot the price was quoted against, and commit future lots to match it. With those clauses in place, the per-tonne figure stops being a guess and becomes what it should be: a controlled input to your landed cost and your resale margin.

Frequently Asked Questions

What is the price of landscape gravel per ton?

There is no single figure, because the grade you buy sets the price: a washed 10–20 mm single-size grade costs more per tonne than a broad graded run of the same stone, and a tight band or a strict colour tolerance adds reject cost that the passing tonnes must cover. Plan with the structure — one 20 ft container holds about 24–27 tonnes, freight is charged per container, and the landed cost per tonne equals material plus packing plus freight divided by the tonnes loaded.

How many tonnes of landscape gravel fit in a 20 ft container?

About 24–27 tonnes loose, because landscape gravel reaches the container's weight limit well before it fills the roughly 33 cubic metres of internal volume. A 40 ft container is not the better deal: its payload is only marginally higher under the same weight limits, and destination road rules often cap axle loads further. Packing reduces the payload — palletized 20–25 kg bags typically load 10–20% fewer tonnes than loose lined loading.

How much area does one tonne of landscape gravel cover?

At a loose bulk density of about 1.4–1.6 tonnes per cubic metre, one tonne covers roughly 20–23 square metres at a 30 mm finished depth, 12–14 square metres at 50 mm, and 8–9 square metres at 75 mm. Add 5–10% for site loss, and reduce coverage further on compacted applications, where compaction raises the effective density by 10–15%.

Why is washed landscape gravel more expensive per tonne?

Washing adds water handling, drying and another reject stream to the production line, and the washed-out dust and fines are tonnes the plant cannot sell, so the passing tonnes carry that cost. In return you get a grade that stays clean in a decorative bed and does not throw dust on paving. For drainage or self-binding path applications the requirement differs — drainage needs washed single-size material, while self-binding gravel must keep its fines — so buy washed only where the application needs it.
