Quick answer: budget 26–28 m³ of usable space in a 20ft container and 65–68 m³ in a 40ft High Cube. That is about 430 master cartons — roughly 43,000 × 100 ml bottles or 215,000 × 10 ml bottles in a 20ft, and around 108,000 or 540,000 of the same sizes in a 40HC. The number of glass bottles per container always depends on three variables: bottle size, carton packing and payload limits.
This guide gives you the container specs, a packing plan by bottle size, pallet math and the weight ceiling — so you can calculate your own load before you book freight.
Every quotation we send ends with the same question: how many glass bottles per container will actually fit, and does the order fill a 20ft box, a 40ft box or only part of one? For a cosmetic brand, the answer decides whether the freight component of your cost per bottle sits at a few cents or quietly eats your margin. Below are the container figures buyers use in real purchase orders, a packing plan by bottle size, and the pallet and weight maths that decide the final count.
Container Capacity at a Glance: 20ft vs 40ft vs 40ft High Cube
Three boxes carry almost every glass bottle shipment: the 20ft General Purpose (20GP), the 40ft General Purpose (40GP) and the 40ft High Cube (40HC). All of them are 2,352 mm wide inside, so length and interior height are what change.
| Container | Internal L × W × H (mm) | Nominal capacity | Usable space* | Max payload |
|---|---|---|---|---|
| 20ft GP | 5,900 × 2,352 × 2,393 | 33.2 m³ | 26–28 m³ | 30,200 kg |
| 40ft GP | 12,032 × 2,352 × 2,395 | 67.7 m³ | 55–58 m³ | 28,800 kg |
| 40ft High Cube | 12,032 × 2,352 × 2,700 | 76.3 m³ | 65–68 m³ | 28,650 kg |
| 45ft High Cube | 13,556 × 2,352 × 2,700 | 86.0 m³ | 74 m³ | 27,800 kg |
*Usable space allows 10–15% for broken stowage. Payload figures are for wooden-floor general purpose containers (max gross weight 32,500 kg).
Two details catch buyers out on their first order:
- Nominal capacity is not usable capacity. Cartons never fill a box perfectly. Freight planners allow 10–15% for broken stowage, which is why a 20ft rated at 33.2 m³ is planned at 26–28 m³.
- Door height, not ceiling height. The rear door of a 20GP or 40GP is 2,292 mm high, even though the interior is 2,393 mm. A pallet stacked to 2.4 m cannot be pushed through it — and a 40HC door is 2,597 mm, which is why taller pallets usually ship in a High Cube.
Dimensions, door openings and payload figures come from the Hapag-Lloyd container specification (internal dimensions standardised under ISO 668); the usable-space allowance follows standard freight planning practice documented in this 20ft / 40ft container size guide.
How Many Glass Bottles Fit in a 20ft or 40ft Container? A Packing Plan by Size
Glass bottles per container are decided by the master carton, not by the bottle. A standard export carton of 500 × 400 × 300 mm occupies 0.06 m³, and how many bottles sit inside it depends on bottle diameter and how the carton is divided with inner grid partitions. The table below is a realistic plan for grid-divided cartons.
| Bottle size | Weight incl. closure | Bottles per carton | Bottles per 20ft (26 m³) | Bottles per 40HC (65 m³) |
|---|---|---|---|---|
| 10 ml (roll-on / oil) | ~28 g | 500 | ~215,000 | ~540,000 |
| 30 ml | ~65 g | 300 | ~129,000 | ~324,000 |
| 50 ml | ~95 g | 200 | ~86,000 | ~216,000 |
| 100 ml | ~185 g | 100 | ~43,000 | ~108,000 |
| 200 ml (diffuser) | ~420 g | 60 | ~26,000 | ~65,000 |
Load calculation you can copy
Usable container volume ÷ master carton volume × bottles per carton = bottles per container
65 m³ ÷ 0.06 m³ = 1,083 cartons × 100 bottles = 108,300 × 100 ml bottles per 40ft High Cube
Change either variable and the answer moves fast. A slim 10 ml roll-on packs around 500 pieces per carton while a 200 ml reed diffuser packs about 60 — so two brands shipping the same litres of product can load completely different quantities into the same vessel. Carton dimensions and pieces per carton are fixed at sampling stage, and we confirm them on the packing list before booking. You can compare bottle diameters and neck sizes on our custom perfume bottle sizes page, check dropper and roller options on the glass essential oil bottles page, and see brush and cap dimensions for the nail category on custom nail polish bottles.
How Many Pallets Fit in a Container? Euro vs GMA Pallets
If your order is palletised rather than floor-loaded, pallet dimensions decide the pallets per container before bottle size does. Euro pallets (1,200 × 800 mm) load 11 per 20ft and 24–25 per 40ft, while US GMA pallets (1,200 × 1,000 mm) load 9–10 per 20ft and 20–21 per 40ft.
| Pallet type | Footprint | Pallets per 20ft | Pallets per 40ft / 40HC |
|---|---|---|---|
| Euro pallet (EPAL 1) | 1,200 × 800 mm | 11 | 24–25 |
| US GMA pallet | 1,200 × 1,000 mm | 9–10 | 20–21 |
Now the trade-off, in cartons. A Euro pallet with a 1,200 × 800 mm footprint takes four 500 × 400 mm cartons per layer (2 × 2). Stacked six layers high that is 24 cartons per pallet, so 11 pallets carry 264 cartons into a 20ft — against about 430 cartons if exactly the same bottles are floor-loaded. Roughly 39% of the container is spent on pallet footprints and lost stack height.
In a 40ft High Cube the gap is wider: 24 pallets × 24 cartons = 576 cartons, versus about 1,083 cartons floor-loaded, close to half the box. Floor-load grid-divided cartons when your distributor can handle loose cartons at the destination, and palletise when goods move straight into a third-party warehouse or when manual handling damage is the larger risk.
Weight Limits: When Glass Bottles Stop Cubing Out and Start Weighing Out
Volume is only half the calculation. Every container has a maximum gross weight of 32,500 kg including the box itself, so the payload you can fill is smaller:
| Container | Tare weight | Max payload (32,500 kg gross) | Concentrated load limit |
|---|---|---|---|
| 20ft GP | 2,300 kg | 30,200 kg | 4.8 t per running metre |
| 40ft GP | 3,700 kg | 28,800 kg | 3.0 t per running metre |
| 40ft High Cube | 3,850 kg | 28,650 kg | 3.0 t per running metre |
Run our packing plan against those limits and the pattern is clear. A 40HC loaded with roughly 108,000 × 100 ml bottles weighs about 20 tonnes — comfortably inside the 28,650 kg payload, so the shipment cubes out and every carton you can fit is free capacity. Load the same box with 200 ml diffuser bottles at about 420 g each and 65,000 pieces comes to roughly 27 tonnes, within a few hundred kilos of the ceiling: the load now weighs out, and the right answer is fewer cartons, a second container or a lighter bottle spec.
Two more limits matter for glass. First, weight has to be spread — a 20ft box may take 4.8 tonnes per running metre, a 40ft only 3.0 tonnes, so concentrate heavy pallets evenly along the floor. Second, road and rail limits are usually lower than the container rating, so the box may be legal at sea but overweight on the truck. Freight planners quote roughly 21,800 kg of road-legal payload for a 20ft and about 21,500 kg for a 40ft, which is the number that actually governs a US or EU delivery. That is the classic cubing out versus weighing out decision, and for heavy glass sizes it is worth modelling before production rather than after.
LCL or FCL? Matching the Load to Your Order Volume
For a first order, the real question is usually not which container — it is whether to ship LCL at all. Groupage keeps cash free when your cartons would fill only a corner of a 20ft, but cost per bottle rises quickly because LCL is charged by volume plus handling and destination fees. As a working rule, once a shipment approaches half of a 20ft container, FCL normally works out cheaper per bottle and arrives with far less handling.
- Stock bottles: MOQ is 1,000–3,000 pcs for stock perfume bottles and 3,000 pcs for stock essential oil bottles — small enough to test a market with LCL.
- Custom colour and logo: MOQ is typically 5,000–10,000 pcs, which pushes an order towards a part-loaded 20ft.
- High Cube premium: carriers often charge only $100–$300 more for a 40HC than a 40GP while adding about 8.6 m³ — the cheapest extra volume in packaging logistics.
Plan the load before the artwork, not after. Bottle diameter, decoration method and whether you colour spray or frost the bottles all affect carton size, and our bottle customization options are confirmed on a pre-production sample so the carton specification is locked before mass production starts.
