Definition
DACH–Poland routes for silo tanker transport are regular bulk material haulage relations by silo tanker between Poland and German-speaking markets — Germany, Austria and Switzerland — based on the A4/A8 motorway corridor and on load consolidation at a transloading terminal before export. In practice, this means that granulate brought in in big-bags or octabins is transloaded onto a silo tanker and shipped west in bulk as a single, full load.
Looking at this from the perspective of the Chorula terminal: our location — 4 km from the A4 motorway interchange and about 180 km from the German border — is no accident. It is geography that turns Upper Silesia into a natural transloading point for all granulate traffic on the Poland–DACH axis.
Why Chorula is the Poland–DACH hub
The terminal’s location decides the entire logistics chain. The A4 slip road is within a few minutes’ reach, and the motorway itself runs unbroken to the west: through Opole, Wroclaw, all the way to the border at Zgorzelec/Görlitz. It is the only Polish motorway that connects directly with the German network toward Dresden — and that makes the A4 the backbone of all bulk export to the German market.
For a DACH recipient, this means predictability. A silo tanker leaving Chorula in the morning reaches the border in 2–2.5 hours, and Dresden the same day. The terminal plays a dual role here: it is a buffer warehouse for 2,000 big-bags and a transloading point with a throughput of 200 tonnes per day. Granulate from several suppliers can be consolidated here, then shipped as one homogeneous load, with no empty runs and no packaging on the recipient’s side.
The heart of this operation is transloading without pneumatics — granulate moves from the big-bag into the silo tanker’s vessel by gravity, with no blowers, so the grain is not mechanically damaged. For the high-purity polymers heading to the German market, that is a difference in quality, not cosmetics. We describe the whole process in our big-bag to silo tanker transloading service.
The A4/A8 corridor — anatomy of the route
A DACH route is easiest to break down into segments. The first is the Polish A4: Chorula → Wroclaw → Zgorzelec, with the Görlitz border crossing. On the German side, the A4 leads to the Dresden interchange — and here the route branches depending on the destination.
| Destination in DACH | Route after Dresden | Approximate distance from Chorula |
|---|---|---|
| Saxony (Dresden, Leipzig) | A4 / A14 | ~250–350 km |
| Berlin and Brandenburg | A13 north | ~500 km |
| Bavaria (Nuremberg, Munich) | A9 → A8/A6 | ~600–750 km |
| Baden-Württemberg (Stuttgart) | A9 → A6 → A8 | ~750–800 km |
| Austria (Linz, Vienna) | A17 → Czech D motorways south | ~600–700 km |
| Switzerland (Basel) | A8 west | ~900 km |
Dresden is the distribution node of the entire axis. From it, traffic spreads onto the A17 toward Czechia and Prague, the A13 to Berlin, and the A9/A8 deep into southern Germany, Austria and Switzerland. For Austria, cutting through Czechia on the D motorways is often more favourable, but the starting point stays the same — leaving Chorula onto the A4.
For the full context of the haulage technology itself, it is worth looking at the article on silo tanker transport, where we describe the entire cycle from loading to unloading at the recipient.
The Euro 6 fleet and low-emission zones
The German market has its own entry rules that cannot be circumvented by route planning. Most major cities — Dresden, Leipzig, Berlin, Munich, Stuttgart — maintain low-emission zones (Umweltzone). Entry requires a green sticker, grüne Plakette, granted to vehicles from the Euro 4 standard upward.
Our fleet consists of 26 DAF XF 480 Euro 6 tractor units — the highest emission standard in force in the Union. This means that no recipient’s plant in an urban zone is inaccessible to us because of emissions. This is no trifle: some German plastics producers have warehouses and silos exactly within the zones, and the lack of a green sticker would rule out delivery right up to the silo. On top of that come 31 silo tankers with a capacity of about 60 m³ in the Spitzer SF/SK and Feldbinder EUT/KIP series, with Storz-standard couplings — equipment matched to the unloading infrastructure on the German side.
A logistically important point: everything we carry across the EU is non-ADR. Granulates of polyethylene (PE), polypropylene (PP), PVC, PET, mineral powders — none of these loads is a dangerous good. That simplifies clearance and route selection: no tunnel restrictions or ADR bans apply, no orange plates or ADR driver qualifications are needed, and the load itself can travel along any of the corridors without detours.
Transit time versus driver working times
On DACH runs, the delivery deadline is decided not by speed but by law. Regulation 561/2006 limits daily driving time to 9 hours (twice a week it may be extended to 10) and requires a 45-minute break after 4.5 hours of driving. The digital tachograph monitors this to the minute, and BAG checks on the German side are frequent and effective.
This dictates the planning logic:
- Saxony (Dresden, Leipzig) — one day of driving, unloading within the daytime shift window.
- Berlin, Bavaria, Baden-Württemberg — one to two days, with a scheduled overnight stop on the German side.
- Austria, Switzerland — as a rule the second day of the run, with unloading in the morning after an overnight stop.
The route is laid out so that the border and urban zones do not fall in the middle of the mandatory break — the point is to keep the driver from losing the recipient’s unloading window. That is why consolidation at the terminal makes timing sense: a silo tanker loaded in advance in the evening sets off at dawn and turns the entire daytime shift into real progress toward the destination, without waiting for the load to be picked en route.
In practice, it is the transloading on the Polish side that buys time on the route. If the same granulate travelled to DACH in big-bags on a curtain-sided trailer, the recipient would have to unpack it, cut it open, empty it by hand and dispose of the packaging — hours of warehouse labour plus the cost of disposing of PP film. A silo tanker unloads pneumatically into the silo in 60–90 minutes with no warehouse staff involved. From the standpoint of driver working times, this means the unloading window is short and predictable, so a return load can often still be hooked up the same day instead of running empty back to Poland.
Empty inbound versus return loads
The economics of DACH routes rest on avoiding empty kilometres. From southern Germany, Austria or Czechia one rarely returns with the same type of granulate, but often with another bulk material for a Polish recipient or with a batch for transloading at the terminal. A silo tanker that has unloaded PE near Stuttgart can pick up mineral powder or PVC on the return run in the opposite direction. Here again, the absence of ADR is the deciding factor — a homogeneous, harmless load can be switched quickly, without re-equipping the vehicle and without additional dangerous-goods documentation. The planner pairs the relations so that the Euro 6 tractor spends as little time as possible running empty, and the driver’s tachograph closes on a full, profitable cycle.
The terminal’s role as a consolidation point
The most important value the terminal brings to DACH routes is consolidation. The German recipient wants granulate in bulk, ready for pneumatic blowing into the silo — they do not want to cut open hundreds of big-bags or dispose of packaging. We do that for them on the Polish side.
The process looks like this: big-bags and octabins from many suppliers go to the warehouse as a buffer. From there, as the order is picked, they are transloaded onto a silo tanker into a full load of 24–25 tonnes of homogeneous material. Where an order requires blending batches or repackaging, packaging/contract finishing comes in. The result: one vehicle, one load, zero empty runs and zero packaging to dispose of at the recipient.
This model serves regular clients in the plastics industry, for whom the terminal is a permanent link in the export chain to the German-speaking market. Geography, the Euro 6 fleet and consolidation combine here into a single advantage: predictable, one-day delivery of granulate from Upper Silesia right up to the DACH recipient’s silo.
Consolidation for export is also a topic for octabins and big-bags (FIBC) — every silo route west begins with these forms of packaging.
Tank cleanliness on the DACH run
The German plastics recipient is demanding about cleanliness. Food-grade or technical-grade granulate cannot travel in a vessel that previously held another batch without proper washing — cross-contamination in this industry means a complaint against the entire load. That is why a silo tanker undergoes a vessel cleanliness check before loading for a DACH route, and where the specification requires it, washing at a tank-cleaning station with an ECD (EFTCO Cleaning Document). Storz-standard couplings fit German unloading stations, so the driver connects the hose without adapters.
This matters logistically, because washing and drying the vessel take additional hours that must be built into the run’s schedule. In route planning they are accounted for just like the driver’s break — a batch with a high cleanliness regime starts from the terminal, where the vessel is prepared in advance, not en route. For moisture-sensitive materials (some PE, polyamides) there is also a moisture check and a hatch tightness check, because over the 700 km route to Bavaria every leak means damp granulate at unloading.
Seasonality and conditions on the route
The A4/A8 corridor is passable year-round, but winter on the Czech and Bavarian sides can change transit times. Mountain segments on the way to Austria and Switzerland are sometimes subject to a winter-tyre and snow-chain requirement — in Germany a situational winter-tyre rule applies, in Austria a calendar-based one. When planning DACH runs in the winter season, a time reserve is added for the Alpine segments and for any heavy-vehicle traffic restrictions that some federal states introduce during intense snowfall.
The second factor is heavy-vehicle traffic bans. In Germany, a Sunday and public-holiday driving ban applies to vehicles over 7.5 t (Sonn- und Feiertagsfahrverbot) between 00:00 and 22:00, and in Austria there are additional night-time noise restrictions on selected corridors. For non-ADR bulk materials there are no separate tunnel restrictions, but the German and Austrian holiday calendar must be kept in the shipment plan — a silo tanker stuck before a Sunday ban loses an entire day. That is why we arrange the terminal’s loading windows around the recipient’s calendar, not the other way around.
