Buying Bulk Fertiliser in Australia: Quantities and Freight

Buying bulk fertiliser is not like buying most farm inputs. There is no shelf price, the freight can be a third of what you pay, and the same product can cost noticeably different amounts depending on how much you take and where it is going. This guide sets out how the purchase actually works so you can compare quotes properly.

Why bulk fertiliser has no list price

Three variables move the delivered cost, and none of them are constant:

• Analysis. A tonne of 46-0-0 urea carries 460 kg of nitrogen. A tonne of 15-15-15 carries 150 kg of nitrogen, 150 kg of phosphate and 150 kg of potash. You are buying nutrient, not weight, so comparing per-tonne prices between different analyses is meaningless unless you convert to nutrient units first.
• Tonnage. A full load costs materially less per tonne than a part load, because the freight is spread further and the handling is the same either way.
• Destination. Freight is the variable most likely to decide whether a deal stacks up. Distance matters, but so does whether a B-double can reach your unloading point.

This is why reputable suppliers quote rather than publish. A headline price nobody actually pays helps nobody.

Minimum quantities

Our minimum order is 10–25 MT, depending on the product and the destination. Some analyses and some destinations carry a higher minimum than others.

If you are buying for export, a full 20-foot container sits at roughly 25 tonnes and is almost always the cheapest way to buy per tonne. Fertiliser is dense enough that a 20ft container hits its weight limit while still only part full, which is why it ships in 20ft rather than 40ft boxes.

How to work out what you actually need

Start from the nutrient, not the product

Work out the nutrient your soil test calls for in kilograms per hectare, multiply by your area, then divide by the nutrient content of the product. A 20-0-0 product applied at 100 kg/ha delivers 20 kg of nitrogen per hectare. Across 400 hectares that is 40 tonnes of product to supply 8 tonnes of nitrogen.

Every one of our 130 product pages carries a table showing exactly what one hectare receives at rates from 50 to 300 kg/ha, so you can do this without a calculator.

Then check the freight makes sense

If your tonnage sits awkwardly — say 14 tonnes when a truck carries 28 — it is often cheaper per tonne to take a full load and store the balance than to pay for a part load. Ask for both figures and compare.

What to send with your enquiry

How to read the quote you get back

A quote worth comparing separates the product price from the freight. If it does not, you cannot tell whether you are being charged well for the product and poorly for the cartage, or the reverse. Ours states them separately.

Check also:

• The declared analysis — and whether a Certificate of Analysis is available for the batch you will actually receive
• Validity period — fertiliser pricing moves with international markets and freight availability
• Lead time — and whether it is realistic for your spreading window
• Packing — the format and whether pallets are included or extra
• GST position — whether prices are inclusive or additional

Paying for it

Payment is by bank transfer — EFT within Australia, or T/T for export orders. There is no online payment on this website and there never will be; you receive an invoice and pay it directly.

Storing what arrives

Keep product dry, off the ground and out of weather. Urea and ammonium-based fertilisers are hygroscopic — they draw moisture out of the air and will set hard if left exposed. If you are buying ahead of the season, say so when you enquire and we will recommend packing that suits storage rather than immediate spreading.

Where to start

If you know the analysis you want, find it in the product catalogue and send an enquiry from that page. If you have a soil test but are not sure what it translates to, send us the report through soil test matching and we will do the conversion. If no standard grade fits, we will quote a custom blend.
