Check cargo fit before choosing a flexitank

20ft container + single-use flexitank

A flexitank turns a 20ft dry container into a non-hazardous bulk liquid carrier. Common loading ranges are about 16,000-24,000 L, depending on density, payload limits and bag model.

For non-hazardous liquids

Typical candidates include propylene glycol, glycerin, vegetable oils, peanut oil, base oils, food-grade liquids and selected non-hazardous liquid chemicals.

Less packaging than drums or IBCs

Flexitanks reduce drums, IBCs and pallets, increasing net liquid payload and lowering packaging handling at destination.

Check cargo and consignee first

Suitability depends on SDS, density, viscosity, loading temperature, pump access and whether the consignee can discharge flexitanks.

Propylene glycol, glycerin and non-hazardous chemical liquids

Review whether flexitank can replace drums or IBCs.

Check non-DG SDS status, density, viscosity, cargo temperature, crystallization risk, heating needs and discharge pump capability.

Peanut oil, vegetable oil and food-grade liquids

Start with food-grade flexitank, clean liner and clean loading control.

Confirm COA, food-contact requirements, allergen or odor contamination risk, previous cargo concerns and destination food import documents.

High-value or sensitive liquids

Compare flexitank, IBC, drums and ISO tank against insurance and handling risk.

A leak can affect the whole shipment, so verify cargo value, insurance, loading supervision, container condition, valve protection and discharge SOP.

Flexitank knowledge: how the 20ft liquid bag shipment works

20ft dry container with flexitank liner

A practical way to convert a 20GP container into a single-use non-hazardous bulk liquid carrier.

A flexitank normally includes a multi-layer PE bladder, outer protection, valve, bulkhead and container liner.
It fits one-cargo bulk liquid export shipments, especially ocean freight in 20ft dry containers.
Container condition matters: floor, walls, nails, odor, oil stains, door frame and light leakage should be checked.
Payload must be calculated by density, gross weight, container limit, carrier rules and destination road limits.

Non-hazardous liquids that often fit flexitank review

The cargo should be non-DG, stable, pumpable and accepted by the consignee for flexitank discharge.

Propylene glycol and peanut oil are priority keyword products for this service page.
Other candidates include vegetable oil, edible oil, glycerin, sorbitol, base oil, white oil and selected non-hazardous liquid raw materials.
Food-grade liquids need attention to food-contact compliance, odor control, clean loading and destination import requirements.
Chemical liquids still need SDS evidence of non-dangerous classification and compatibility with the liner.

Loading, transit and discharge conditions

Flexitank forwarding succeeds when both origin and destination can handle the liquid safely.

Loading site needs pump, hose, fittings, metering, sampling and spill prevention.
During transit, control overweight risk, door impact, temperature exposure and insurance conditions.
Destination must confirm pump, hose, fitting, emptying procedure, used bag disposal and residual acceptance.
Many failures come from poor container inspection or consignee discharge readiness rather than the ocean voyage itself.

Flexitank vs drums vs IBC vs ISO tank

Check point	Flexitank	Drums / IBC	ISO tank
Best cargo	Non-hazardous bulk liquids such as propylene glycol, peanut oil, vegetable oil and glycerin	Small lots, multiple SKUs or destinations without flexitank discharge ability	Large bulk liquid programs, reusable tank moves, selected DG or higher-control liquids
Payload efficiency	High net liquid payload with less packaging	More packaging and pallet space, lower net payload	Stable bulk carrier but lease and return rules are more complex
Cost structure	Flexitank, liner, loading, ocean freight, insurance and discharge coordination	Drums/IBCs, pallets, labor, storage and packaging disposal	Tank lease, cleaning, demurrage, return location and compatibility approval
Main risks	Leakage, contamination, container condition, overweight, failed discharge, incompatible liquid	Damaged drums, seepage, handling loss and packaging disposal cost	Lease period, cleaning, destination return, tank certificate and cargo compatibility
Quote inputs	Cargo name, SDS, density, viscosity, loading temperature, target liters, loading/discharge address	Package size, pieces, pallets, gross weight and food-grade needs	Medium, tank type, origin/destination, lease period, cleaning and heating needs

Flexitank export workflow from China

01 Cargo reviewCheck SDS, density, viscosity, cargo temperature and food-grade requirements before saying yes to flexitank.
02 Flexitank planConfirm bag capacity, food-grade or chemical-grade liner, valve layout and heating or insulation needs.
03 Container inspectionCheck 20ft container floor, walls, odor, nails and light leakage, then install liner, bulkhead and valve protection.
04 Loading and ocean freightPump liquid into the bag, capture loading photos or video, arrange ocean booking, customs, trucking and sailing.
05 Destination dischargeConfirm pump, hose, emptying process, used bag disposal, residue acceptance and exception handling before arrival.

Risks that decide whether flexitank is suitable

Non-hazardous does not automatically mean flexitank-ready

The liquid must be compatible with the liner and should not corrode, crystallize, ferment, expand or lose flowability at transit temperature.

Density and road limits must be calculated first

The same liter volume can create very different gross weights. Overweight cargo can breach container, road or destination limits.

Container condition drives leakage risk

Nails, floor damage, odor, oil stains and light leakage increase the chance of bag damage or contamination.

No discharge setup means destination delays

Flexitank cargo needs pump, hose, fittings and trained people at destination, otherwise demurrage and extra handling can occur.

Food-grade cargo needs contamination control

Peanut oil and vegetable oils need food-contact suitability, clean loading, odor control and allergen or label review.

Research and operating notes used for this page

Flexitanks are generally used inside 20ft dry containers for non-hazardous bulk liquids; capacity depends on bag model, density and route limits.
Flexitanks are not DG tank containers and should not be used for dangerous liquids, gases, solids or cargo incompatible with the liner.
Propylene glycol, peanut oil, vegetable oils and glycerin are common candidates, but final acceptance requires SDS, product details and loading/discharge confirmation.
This page supports freight pre-check and SEO inquiry capture. It does not replace flexitank supplier compatibility approval, insurance terms, carrier rules or destination import requirements.

FAQ for flexitank non-hazardous liquid shipping

Can flexitanks carry dangerous goods?

Usually no. Flexitanks are mainly for non-hazardous bulk liquids. Dangerous liquids need separate UN/class review and may require drums, IBCs, ISO tanks or other compliant packaging.

Can propylene glycol ship in a flexitank?

Propylene glycol is a common flexitank candidate, but we still check SDS, density, viscosity, loading temperature, destination rules and consignee discharge ability.

Can peanut oil or edible oil use flexitank?

Yes, it is a common review direction. Food-grade liner, clean container, COA, odor control, import documents and discharge conditions matter.

How much can one flexitank load?

Common ranges are about 16,000-24,000 L, but quote should be based on density, gross weight, container limit, road limit, bag model and destination rules.

Flexitank or ISO tank: which is better?

For non-hazardous one-way bulk liquid exports, flexitank often reduces packaging cost. ISO tanks may suit DG cargo, reusable programs, heating needs or higher-control cargo.

What should I send for a fast quote?

Cargo name, SDS/MSDS, density, viscosity, loading temperature, target liters or weight, China origin, destination, food-grade need, loading/discharge addresses and ready date.
