Definition
Granulate import is a supply chain in which plastic in pellet form — most often polyethylene (PE) or polypropylene (PP) — produced in Asia or the Middle East travels by sea in big-bags packed into containers, and after reaching Europe is transloaded at an inland terminal from the bags into silo tankers and delivered in bulk to the processor. In English this stage is called polymer transloading — repackaging the raw material from sea packaging (big-bag) into bulk land packaging (silo tanker), without changing the granulate itself.
Such loads pass through our terminal in Chorula every day: the same raw material arrives at the gate in bags from Korea or the Persian Gulf, and leaves by tanker straight to the customer’s silo in Poland or Germany. Below I break this chain down into its components: why it looks the way it does, where the risks are, and what the terminal actually does within it.
The supply chain step by step
The granulate import chain has several links, each with its own logic. The full route looks like this:
| Stage | Where | Load form |
|---|---|---|
| Production | Korea, the Middle East, other Asian countries | granulate in bulk from the reactor |
| Packing | producer’s plant | big-bag with PE liner, palletised or loose in the container |
| Sea transport | port of dispatch → EU port | 20’/40’ container with big-bags |
| Entry into the EU | Gdansk, Hamburg (also Rotterdam, Antwerp) | container at the quay |
| Inland haulage | port → inland terminal | container on a chassis / big-bags |
| Transloading | Chorula terminal | big-bag → silo tanker |
| Distribution | terminal → processor PL/DE | silo tanker in bulk |
Every arrow in this table is a separate logistics decision. Most misunderstandings concern two changes of form: from bulk to big-bag at dispatch, and from big-bag back to bulk at delivery. These two determine the quality and cost of the whole operation.
Why imports go in big-bags and distribution by silo tanker
This is the most frequently asked question, and the answer is simple: the sea likes a container, the factory likes a silo, and the granulate has to survive both worlds.
On a transoceanic route there is no sensible way to carry loose granulate by tanker — a silo tanker cannot go onto a ship, and loose raw material in a container has to be stabilised somehow and shielded from moisture, sea salt and dirt. A big-bag (FIBC) with an internal PE liner solves all of this at once: it provides a rigid load unit of ~1000 kg, a sealed layer protecting against moisture, and a simple way to fill the container completely. That is why the producer in Asia packs the granulate into bags, even though it comes out of the reactor in bulk.
On the other side of the world, the processor wants exactly the opposite. An injection-moulding line or an extruder is fed raw material from a silo, supplied automatically. Cutting open hundreds of big-bags by hand at the production line means cost, dust and a risk of contamination. That is why the final leg — from the terminal to the factory gate — is done by silo tanker, which pours the granulate straight into the customer’s silo.
Between these two worlds, someone has to convert one form into the other. That is precisely the role of the inland terminal.
The role of the inland terminal
In the import chain the terminal performs four functions at once, and that is exactly why it makes sense to plug it in here instead of hauling bags straight from the port to the customer.
Packaging change point. What arrives at the port is a container with big-bags — not a tanker. Someone has to unpack those bags and transfer the granulate into the silo tanker. We do this in the hall: the big-bag goes to a station, we untie the outlet and pour the contents by gravity into the tanker manhole. We transload this way up to 200 tonnes a day.
Time buffer. A ship brings the entire batch at once, while a factory consumes it evenly over weeks. Our warehouse for 2000 big-bags takes in the whole load from the containers and releases it by silo tankers at the pace of the recipient’s production. This decouples the rhythm of the sea from the rhythm of the line — a topic explored in the article on bulk material storage.
Consolidation and splitting. A single import batch often goes to several processors. At the terminal it can be split into smaller silo-tanker deliveries, or the other way round — several containers can be consolidated into one continuous stream of releases. This is classic bulk material cross-docking, only with a change of packaging in the middle.
Quality control. During the transfer we can inspect the granulate, pass it through a screen and reject damaged bags. This is the moment when it is easy to catch a problem before the raw material enters the customer’s silo.
What happens at the port and why it is not enough
Importers sometimes ask whether the whole thing could be handled at the port itself. The answer is: at the port sea logistics ends and land logistics only begins — and these are two different worlds.
After the ship arrives, the container clears customs and is released for circulation in the EU. Polymer granulate is not a dangerous good (ADR), so customs clearance proceeds in the standard way, but time matters here: charges accrue for keeping the container at the port terminal (demurrage) and for the chassis itself (detention). The sooner the container leaves the port and returns empty, the cheaper it is. That is why it pays for the importer to pull the container out of the port quickly — inland, to the terminal, where it can be unloaded at leisure and the empty chassis returned.
The port is also not a place to store big-bags for weeks, nor to transfer granulate into tankers — that is not its role and not its rates. So separating the functions makes sense: the port handles the sea, the inland terminal handles the change of packaging, the buffer and bulk distribution. Two links, each doing what it does cheaply.
In practice, what reaches us is either whole containers on a chassis (we unload them at our site and return them empty) or just big-bags already taken off the container at a nearby dry port. Both variants end the same way — with a bag at the transloading station.
Location: why Chorula in particular
In imports, geography is not a detail. Chorula lies 4 km from the A4 motorway and close to the German border — at a natural hub between the Baltic ports and the DACH market.
Containers from Gdansk come down the A1 → A4 here in a few hours. Loads via Hamburg (as well as Rotterdam and Antwerp) reach the A4 from the west. From this same point a silo tanker has a short run to both Polish processors (Silesia, Greater Poland, Lesser Poland) and German recipients — and it is this final leg that determines the cost and time of a bulk delivery. We describe the routes towards DACH separately in bulk transport by silo tanker.
We operate a fleet of 26 DAF XF 480 Euro 6 tractors and 31 silo tankers with a capacity of ~60 m³, so after transloading the raw material sets off without waiting for an external tanker to be provided.
Transloading without pneumatics protects the imported raw material
This is the point I care about most, because it determines the quality of the entire import. Granulate that has travelled halfway around the world is easiest to ruin on the very last metre — in bad transloading.
In pneumatic systems the granulate is pushed by compressed air through a pipeline. Along the way it rubs against the walls and against itself, which abrades particles off the pellets — angel hair and dust are created, and the raw material itself becomes statically charged. For the processor this is a real problem: angel hair blocks dosing, the electrostatic charge attracts contaminants, and the fine fraction degrades product quality.
We transload without pneumatics — by gravity. We untie the big-bag over the silo tanker manhole and the granulate simply pours downwards. There is no compressed air, no pipeline, no friction. The imported raw material reaches the customer in the state it left the bag in at the producer in Asia. For sensitive materials, or when the recipient requires it, we run the transfer through a cleaning screen that catches lumps, foreign bodies and fractions that deviate from the specification.
We handle granulates and bulk materials that flow well and are not dangerous goods (ADR) — PE, PP, ABS, PS, PA, PET and similar. Imported polymer granulate fits entirely within this profile.
Purity, documentation and responsibility for the batch
Granulate import is not just physical carriage — it is also responsibility for ensuring the raw material arrives in line with the specification. A processor pouring someone else’s granulate into its own silo must be sure it will not contaminate its line.
That is why a silo tanker for such a load has to be clean and dedicated. We apply the tanker cleanliness standard known from the chemical industry — after each load the tanker has a documented status, and for polymer raw material transport we select tankers that have not previously carried material that could taint the batch. This reduces cross-contamination at the source. The silo tankers’ couplings are standard Storz, so connecting to the customer’s installation is unambiguous and tight.
The second filter is the cleaning screen along the transfer path. After a long journey, imported granulate is sometimes caked together or contains the odd foreign body from the packing process — the screen catches this before it reaches the tanker. The third element is the very fact that we work by gravity: without pneumatics we add no dust or angel hair to the batch, so the raw material’s parameters from the bag and from the tanker match.
We also follow Operation Clean Sweep — a voluntary industry programme that commits to zero tolerance for spilled pellets in the environment. In imports, where bags are cut open and transferred, this is real working discipline: enclosed stations, catching spillage, a clean hall.
A typical import scenario
So that this is not too theoretical, let me show what an average batch we handle looks like.
A producer in Korea packs PE or PP into big-bags with a liner, loads them into 40’ containers and ships them by sea. After a few weeks the containers come off the ship in Gdansk, clear customs and travel by chassis along the A1/A4 to Chorula. They enter our gate, the container goes for unloading, and the big-bags go either straight to the transloading station or to the warehouse, if the customer takes the goods in batches.
When a processor in Poland or Germany reports demand, we bring up a silo tanker, untie successive big-bags over its manhole and fill the tank by gravity. If needed, the transfer goes through a screen. The full tanker sets off — from the hub by the A4 it has a short run to most European plastics recipients. The granulate reaches the customer’s silo in bulk, ready to be fed to the line, intact from the moment it was packed in Asia.
We close this whole leg — from the port to the factory gate — at our site, so the importer has a single partner for the land part of the chain instead of assembling it from several subcontractors.
Benefits for the importer and the processor
Putting it all together, bringing an inland terminal into granulate import delivers concrete, quantifiable effects:
- Consolidation — several containers from different deliveries converge at one point and one stream of releases.
- Buffer — the factory does not have to take in the whole batch at once or keep its own warehouse for bags; it takes silo tankers at its own pace.
- Transloading without disturbing the granulate — gravity transloading protects the quality of the raw material the importer has already paid for.
- Shortened final leg — bulk delivery from the hub by the A4 instead of hauling bags across half of Europe.
- Purity control — the screen and clean tankers reduce cross-contamination before the raw material enters the silo.
In practice, the importer delivers the container and we close the chain to the processor’s gate — without an extra intermediary, without cutting bags open by hand at the production line, and without the risk of the raw material losing its parameters on the way. In this model we serve regular recipients from the plastics processing industry.

Granulate import ties together several threads from the encyclopedia. On the packaging side, these are the big-bag (FIBC) and silo tankers; on the technology side — transloading without pneumatics and cleaning screens; on the logistics side — bulk transport by silo tanker, storage and cross-docking. The raw material itself is described in the entries PE — polyethylene and PP — polypropylene.
