Last updated: 2026-10-06 · 12 min read · By Tùng Trần, Founder & Sourcing Director
Key takeaways
- Three of seventeen audited supplier sites publish container load, and their figures differ — all correctly
- The constant is not tonnage but carton count: roughly 700 cartons per 20-foot container
- Cashew cartons fill the container's volume long before they reach its weight limit
- Carton net weight varies by packing family: 20 kg (2 × 10 kg) or 22.68 kg (2 × 11.34 kg, the 50 lb AFI carton)
- Moving from 20 kg to 22.68 kg cartons cuts freight per kilogram by roughly 12%

Why do suppliers quote different tonnage per container? {#different-tonnage}
Because tonnage depends on carton weight, and carton weight depends on packing format. In our September 2026 audit, three Vietnam supplier sites published container loads of roughly 15.9 MT, 14 MT and 16–18 MT per 20-foot container. All three are consistent once you know how each supplier packs.
This is one of the most common sources of confusion for buyers comparing quotes, and it looks like a discrepancy when it is really a units problem.
Work the arithmetic backwards and the pattern appears immediately:
| Published load | Carton net weight | Implied cartons |
|---|---|---|
| 15.876 MT / 20′ | 22.68 kg | 700 |
| 14 MT / 20′ | 20 kg | 700 |
| 28 MT / 40′ | 20 kg | 1,400 |
Two different suppliers, two different carton standards, one identical carton count. The 16–18 MT figure from the third site is a range precisely because that supplier offers several packing options and did not fix one.

Why 700 cartons? {#why-700}
Because cashew cargo runs out of space before it runs out of weight. A 20-foot container's payload allowance is far above 16 MT, but roughly 700 cashew cartons already fill its internal volume. The container cubes out, so the binding constraint is carton count, not tonnage.
Compare the two limits. A standard 20-foot container's weight allowance sits well above 20 MT, while the loads above land between 14 and 16 MT. The missing tonnage is not caution — it is air. Cashew kernels are a light, bulky cargo, and the cartons occupy the container's cubic capacity while leaving several tonnes of payload unused.
This has a practical consequence that surprises first-time buyers: paying for a denser packing format does not let you ship more product per container. Once the cartons fill the space, the only way to increase net weight per container is to increase the net weight inside each carton — which is exactly what the 22.68 kg carton does relative to the 20 kg one.
That difference is not trivial. Across 700 cartons, the two standards differ by roughly 1.9 tonnes of product moving under the same freight bill.
It also means that any packing change reducing carton density — a bulkier inner unit, extra void fill, oversized cartons — costs you directly. You do not lose weight allowance; you lose product per container while paying the same freight.
What are the standard cashew packing formats? {#packing-formats}
The dominant format is two inner units of 10 kg in a carton, giving 20 kg net. The traditional international standard is the 50 lb carton at 22.68 kg net, made up of two 11.34 kg units. Inner units are either vacuum-sealed polyethylene bags or sealed tins.
Six of seventeen audited sites published a packing format. Where they did, the structure was consistent: an inner unit around 10 kg, two units per carton.
| Format | Inner unit | Carton net | Typical use |
|---|---|---|---|
| PE vacuum bag | 10 kg × 2 | 20 kg | General export, most markets |
| Tin (sealed) | 10 kg × 2 | 20 kg | Middle East, long transit |
| 50 lb AFI carton | 11.34 kg × 2 | 22.68 kg | Traditional international standard |
| Flexi / bulk bag | varies | varies | Industrial processors |
| Retail-ready | small packs | varies | Private label, direct retail |
The two-unit carton is not arbitrary. It gives a carton a person can lift, splits a consignment into units small enough that opening one does not expose the whole carton to air, and stacks predictably.
Flexi and bulk formats appear where the buyer is an industrial processor emptying large quantities into a production line. They reduce packaging cost per kilogram but sacrifice the partial-use advantage: once opened, the whole unit is exposed.
Vacuum bag or tin — which should I choose? {#bag-or-tin}
Choose vacuum bags for cost efficiency on normal transit routes and tins where transit is long, humid, or the destination market expects them. Tins cost more per kilogram and add tare weight, but resist crushing and moisture ingress in ways a bag cannot.
Vacuum-sealed PE bags are the default for good reasons. They are light, cheap, and vacuum sealing removes the oxygen that drives rancidity in a high-oil kernel. For most routes into Europe, North America and Asia, they are the correct answer and nothing further is needed.
Tins earn their premium in specific conditions. Middle East buyers commonly prefer them, partly for humidity resistance across the transit and storage chain, and partly because the format is established in that trade. They also survive rough handling that would compromise a bag seal, and a compromised vacuum seal is a quality problem that only appears on arrival — by which point establishing when it happened is difficult.
There is a third consideration that rarely appears in quotes: how the goods will be handled after they clear customs. A consignment moving straight into a controlled warehouse and out to production within weeks has different requirements from one sitting in a distributor's shed through a humid season. Buy packing for the whole chain, not just the ocean leg.
How does packing affect shelf life? {#shelf-life}
Cashew kernels are high in oil, so shelf life is governed by oxygen exposure and moisture. Vacuum sealing removes oxygen at packing; nitrogen flushing replaces it with an inert gas. Both extend usable life substantially compared with simple sealed bags, and both depend on the seal remaining intact through transit.
The failure mode to design against is rancidity, not spoilage. A cashew that has oxidised does not look wrong; it tastes wrong, and it usually reaches that point without any visible signal that would prompt a warehouse to reject it.
Three variables control the outcome:
Oxygen at packing. Vacuum sealing and nitrogen flushing both address this. Nitrogen flushing is more common in retail-format packs where a hard vacuum would crush the product visually.
Seal integrity through transit. A perfect vacuum that fails in week two is worse than no vacuum, because nobody knows it failed. This is where tin packing earns its cost on rough routes.
Storage after arrival. Temperature and humidity in the destination warehouse frequently matter more than anything the exporter controls, and it is the variable buyers most often overlook when specifying packing.
If your product will sit in stock for months rather than weeks, that expectation belongs in the RFQ. It changes the packing recommendation, and a supplier who does not know it will quote the cheapest compliant option.
Does moisture specification change my packing choice? {#moisture-packing}
Yes, and the two should be decided together. Middle East premium specifications commonly tighten moisture to around 4.5% against the 5% of full AFI specification, precisely because tin packing and long humid transit demand a drier starting point. A tight moisture ceiling in a format that cannot hold it is a specification you will struggle to enforce.
This is the most common incoherence we see in buyer specifications: a strict moisture number paired with the cheapest packing option and a route through the tropics in the wet season. The number is enforceable at loading and unenforceable at arrival, and the resulting argument has no clean answer because both parties are describing different moments in time.
The coherent combinations look like this:
| Specification | Sensible packing | Reasoning |
|---|---|---|
| Moisture max 5%, short transit | Vacuum PE bag | Cost-efficient, adequate barrier |
| Moisture around 4.5%, Gulf destination | Tin | Humidity resistance across chain |
| Moisture max 5%, long storage after arrival | Vacuum PE or nitrogen-flushed | Oxygen control is the constraint |
| Industrial, immediate processing | Flexi or bulk bag | Barrier requirement is low |
Decide the moisture ceiling and the packing format in the same conversation, and specify at which point moisture is measured — at loading or on arrival. That single sentence in a contract prevents a category of dispute entirely.
Is a 40-foot high cube cheaper per kilogram? {#forty-foot}
Usually yes, because a 40-foot high cube holds roughly twice the cartons of a 20-foot container while its freight rate is well below double. For cargo that cubes out rather than weighs out, the larger box spreads fixed handling and documentation costs across more product.
One audited supplier published 14 MT per 20-foot and 28 MT per 40-foot with the same 20 kg carton — 700 cartons and 1,400 cartons respectively. That clean doubling is what you would expect for a volume-limited cargo.
Whether it saves money depends on two things outside the container itself:
Whether you can absorb the volume. Double the container is double the working capital and double the inventory holding period. A saving per kilogram that is funded by four extra months of stock is not always a saving.
Whether your destination handles high cubes easily. Some inland facilities and delivery points have height or handling constraints that make a 40-foot high cube awkward or more expensive to move on the final leg, eroding the ocean-freight advantage.
For a buyer moving regular volume into a facility that handles both, the 40-foot high cube is generally the better unit economics. For a first shipment or an irregular requirement, the 20-foot container's smaller commitment usually outweighs the per-kilogram difference.
Palletised or floor-loaded? {#palletised}
Floor-loading fits more cartons into the same container; palletising is faster and safer to unload. For a cargo that cubes out, pallets cost you product — the pallet footprint and deck height consume volume that would otherwise hold cartons.
The trade-off is between ocean economics and destination labour.
Floor-loaded means cartons stacked directly, hand-loaded and hand-unloaded. It maximises the cartons per container, which for a volume-limited cargo like cashew translates directly into more product per freight bill. It also means someone at destination unloads by hand, which takes hours rather than minutes and requires labour that some warehouses no longer have.
Palletised means cartons stacked on pallets, moved by forklift. Unloading takes a fraction of the time, damage in handling drops, and the goods enter a racked warehouse immediately. The cost is volume: pallet decks and the gaps around them displace cartons, so the container carries less.
Two additional factors decide it in practice:
Destination handling capability. If your warehouse charges for manual devanning or cannot supply the labour, the freight saving from floor-loading can be consumed at the door.
Pallet compliance. Wooden pallets crossing borders must meet international phytosanitary treatment requirements and carry the corresponding mark. Non-compliant pallets are a genuine cause of delay at arrival, and the requirement applies to the pallet independently of the cargo on it.
For most cashew shipments into a facility with devanning capability, floor-loading remains the default. Where labour is scarce or expensive, pallets earn their volume cost back at unloading.
What about retail-ready and private label packing? {#retail-ready}
Retail-ready packing shifts work from your facility to the supplier's, and shifts cost from your operation to your landed price. It reduces container net weight because small packs and their outer cases are far less dense than bulk cartons, so expect meaningfully fewer kilograms per container.
The trade is straightforward once stated plainly. You save handling, labour and a packing line at destination. You pay more per kilogram, and you ship air — because a container of 200-gram retail packs holds much less product than a container of 10-kilogram bags.
Three questions decide whether it is worth it:
Do you have packing capability at destination? If not, the comparison is not bulk versus retail-ready — it is retail-ready versus building a line.
How stable is your artwork and SKU mix? Retail-ready packing commits you to a design and a format at the point of order. Bulk keeps that decision until much later, which is worth real money for a product still finding its market.
Does the private label add a compliance layer? Retail packaging carries labelling requirements specific to the destination market — nutrition declarations, allergen statements, language rules. Confirm who is responsible for label compliance in the contract, because the answer is not obvious and getting it wrong stops product at customs.
How does packing change my landed cost? {#landed-cost}
Packing affects landed cost twice: directly through packaging material, and indirectly through how much product travels under one freight bill. Since container freight is charged per container rather than per kilogram, a carton standard carrying more net weight spreads the same freight over more product.
Take the two carton standards across one 20-foot container:
- 700 cartons × 20 kg = 14,000 kg
- 700 cartons × 22.68 kg = 15,876 kg
Same container, same freight invoice, 1,876 kg difference in cargo. Whatever your ocean freight figure is for that lane, dividing it by 15,876 rather than 14,000 lowers freight cost per kilogram by roughly 12%.
This is why comparing two quotes on price per kilogram alone can mislead. A slightly higher per-kg price with a denser carton standard can land cheaper than a lower per-kg price in a lighter carton — and neither quote will mention it, because only three of seventeen sites publish container load at all.
Tare weight deserves a line of its own here. Tins weigh more than bags, and that weight travels with your goods. Confirm whether a quoted price is per kilogram of product or per kilogram gross; with bags the distinction is minor, with tins it is not.
What to verify before the container seals {#verify}
Confirm four numbers and one process: carton net weight, cartons per container, total net weight, marking, and who supervises loading. These reconcile against each other, so a mismatch in any one of them signals an error worth resolving before the goods sail.
Carton net weight. Not gross, not inner unit — carton net. This is the figure every other calculation depends on.
Cartons per container. If this does not reconcile with carton weight and stated tonnage, ask. It is usually a copy-paste error between quotation templates.
Total net weight. Multiply the first two and check it against the contract quantity and its stated tolerance.
Marking. Carton markings determine whether your warehouse can identify the goods on arrival and whether customs can match them to your documents. Specify what must be printed and in which language.
Loading supervision. Someone should confirm that the inspected goods are the goods that entered the container. An inspection without loading supervision verifies that compliant product existed, not that it shipped.
Getting packing right is unglamorous work that moves landed cost further than most price negotiations do. It is a routine part of what HotaNuts does as a Vietnam-based sourcing and export partner — reconciling packing, carton count and container load before a contract is signed, and coordinating loading supervision so the arithmetic on paper matches what is in the box.

Frequently Asked Questions
How many tonnes of cashew fit in a 20-foot container?
Roughly 14 to 16 tonnes, depending on carton standard. The constraint is volume rather than weight: around 700 cartons fill the container, so net tonnage follows from carton net weight — 20 kg cartons give 14 MT, 22.68 kg cartons give about 15.9 MT.
Why do cashew containers not load to their full weight limit?
Cashew kernels are a light, bulky cargo that fills a container's cubic capacity before reaching its payload allowance. The cartons cube out, leaving several tonnes of unused weight capacity that no packing arrangement can recover.
What is the standard cashew export carton weight?
Two standards are common. The traditional international carton is 22.68 kg net, equal to 50 pounds, made of two 11.34 kg inner units. Many Vietnamese exporters use a 20 kg carton of two 10 kg units instead.
Should I buy cashews in vacuum bags or tins?
Vacuum-sealed bags are cheaper and suit most routes, since vacuum sealing removes the oxygen that causes rancidity. Tins cost more but resist humidity and crushing, which makes them common for Middle East destinations and long or humid transit routes.
Does packing affect cashew freight cost?
Yes. Container freight is charged per container, not per kilogram, so a carton standard holding more net weight spreads the same freight across more product. Moving from 20 kg to 22.68 kg cartons reduces freight per kilogram by roughly 12%.
Is a 40-foot container cheaper per kilogram than a 20-foot?
Usually yes, because it holds roughly double the cartons while its freight rate is less than double. The saving only materialises if you can absorb the extra volume without excessive inventory holding, and if your destination handles high cubes without surcharges.
Does retail-ready packing reduce how much fits in a container?
Yes, significantly. Small retail packs and their outer cases are far less dense than bulk cartons, so a container carries meaningfully fewer kilograms. Weigh the destination handling saved against the higher landed cost per kilogram.
Take the next step
Packing and grade together set most of your delivered cost. The remaining variable is compliance — which certificate your destination market actually requires, and which ones are simply table stakes. Article 5 covers that.
