20-Foot vs 40-Foot Containers: Which Is Better for Shipping Scrap?

Selling scrap in bulk is a completely different game to dropping off a ute load at your local yard, and it helps to know the rules before you start. If you’re new to this side of things, selling scrap in bulk is worth understanding properly, and we’ll cover the essentials here.

When you first look into bulk scrap, a lot of the terminology can feel a bit opaque. Minimum order quantities, container loads, grades, net weights, FOB and CIF terms — none of it is complicated in itself, but there’s quite a lot of it, and it all adds up. The good news is that underneath the jargon, this is a fairly straightforward business of matching material you have with a buyer who needs it. Let’s work through the main pieces so none of it catches you off guard.

How Container Loads Work

When people talk about selling scrap by the container load, they usually mean a standard 20-foot or 40-foot shipping container packed with material. A 20-foot container can generally hold somewhere between 18 and 28 tonnes of scrap metal, depending on how dense the material is and how tightly it’s packed.

There’s also a safety side to this that matters more than most sellers expect. An unevenly packed container can shift in transit, and an overloaded one can be refused at the port or the buyer’s yard. Packing material in layers, keeping the weight distributed, and not exceeding the container’s rated payload are all part of doing this properly.

How Bulk Scrap Is Priced

The price you’re offered per tonne isn’t just about the metal itself. Buyers factor in how much processing they’ll have to do before they can on-sell it, how much it costs to collect it from you, and what grade they can realistically recover. A load that looks identical to another on the surface can be worth noticeably less once those costs are taken into account.

It also helps to understand the difference between a gross price and what you actually take home. Some offers sound high but include deductions for freight, sorting, moisture, or contamination. Others are lower but represent a genuine net figure. Comparing offers properly means looking past the headline per-tonne rate and asking what gets deducted before the money lands in your account.

What Bulk Buyers Are Looking For

A buyer purchasing scrap by the tonne is really looking for three things: material they can rely on, in a quantity that makes the trip worthwhile, at a price that lets them make a margin. Consistency matters to them far more than a one-off big load, because their own operations are planned around knowing what’s coming in.

Being easy to deal with counts for more than people think. Turning up on time, having accurate weights, providing the paperwork they need, and being honest about what’s in the load all build the kind of trust that leads to repeat business and better prices over time.

Getting Your Scrap Ready

Before a load goes anywhere, it pays to have it sorted, clean, and documented. That means separating the metals you’ve got, keeping non-metallic material out of it, and knowing roughly how much weight you actually have. A bit of effort at this stage almost always comes back as a better price per tonne.

Moisture is an easy one to overlook and it costs people real money. Wet scrap weighs more on the scale, and buyers know it, so they’ll apply a deduction or a moisture allowance to compensate. Keeping material covered and letting it drain before it’s weighed is a simple step that protects the value you’ve actually got.

Working Out How Much You Actually Have

One of the first questions any bulk buyer will ask is how much material you’ve got, and they mean weight, not volume. If you can give them a realistic tonnage, you’re far more likely to get a sensible conversation started. A rough estimate based on what you can see is a reasonable starting point, but an actual weighbridge ticket carries far more weight, literally and commercially.

For businesses that generate scrap steadily, keeping records of what comes out of the workshop each month is genuinely valuable. Even simple notes about roughly how much of each metal you produce give you something concrete to talk to buyers about, and they make it much easier to spot whether you’re reaching the quantities a bulk buyer would find interesting.

Where to Go From Here

Selling scrap in bulk isn’t complicated once you know the rules, and the difference between a good outcome and a mediocre one usually comes down to preparation and knowing what your material is worth. For a thorough walkthrough of selling scrap in bulk, including how minimum orders work, that guide is the best place to start.

Being able to sort your material properly matters, so it’s worth reading how to identify scrap metal before you prepare a load. Once you’ve got the material side sorted, the commercial side falls into place much more easily.

None of this needs to be learned all at once. Most businesses that do well with bulk scrap started by selling smaller quantities locally, learned what buyers actually wanted, and built up to larger loads as their volume and confidence grew. If that’s the path you’re on, the most useful first step is simply to find out what you’ve got and roughly how much of it there is. Everything else follows from there.
