The phrase "customs broker" sounds more official than it usually is. In Poland, we're formally called agenci celni — licensed agents who can act on an importer's behalf when goods cross the border. The licence matters because customs declarations aren't something just anyone can file. But beyond the administrative function, what the job looks like in practice varies considerably.
Here's a practical explanation of what we do — not the regulatory definition, but the actual work.
The core task: preparing and filing the declaration
When goods arrive at a Polish customs point, someone has to formally declare them. That declaration — in Poland, it's filed through the CELINA system using a form called the SAD (Single Administrative Document) — tells customs what the goods are, where they came from, what they're worth, and how they should be classified for duty purposes.
Getting this right requires several things: knowing the correct Harmonised System (HS) code for the product, applying the right customs procedure, calculating duties and VAT accurately, and ensuring the declaration is consistent with the supporting documents — the commercial invoice, packing list, and bill of lading or airway bill.
A broker prepares all of this and submits it electronically. After submission, customs either releases the goods or requests additional information or an inspection. If they request something, the broker handles the communication.
HS codes: why they matter and why they go wrong
The HS code (Harmonised System code) is an eight- or ten-digit number that classifies the product. Customs uses it to determine which duty rate applies. The codes are defined internationally, with additional EU and Polish specifics layered on top.
Getting the code wrong has consequences: you might end up paying the wrong duty rate, which means either overpaying or underpaying and potentially facing a penalty later. Some codes also trigger additional requirements — anti-dumping duties on certain Chinese-origin goods, for example, are applied at the code level.
Chinese suppliers often include an HS code on their commercial invoice, but this is the code they use for their own export declaration. It's not always the same as what Polish customs would assign to the same product. We check this before filing.
What the broker doesn't do
A broker handles the customs filing and the liaison with the customs office. We don't arrange transport, we don't handle warehousing, and we're not freight forwarders. These are different licensed activities. Many importers work with a freight forwarder who handles the logistics of moving the goods, and a separate customs broker who handles the declaration. Sometimes these services are bundled by a single company, but the functions are distinct.
We also don't give legal advice. We can tell you what HS code we believe is correct, but if the classification is disputed or involves a genuinely ambiguous product, the definitive answer comes from a binding tariff information (BTI) ruling from the customs authority — which is a separate process we can help you initiate, but not one we can substitute for.
When you don't need a broker
You can file your own customs declaration if you're importing goods for personal use or if you're an authorised economic operator with the relevant staff and systems. Most small and medium businesses don't do this because the time cost of managing customs declarations in-house outweighs the broker fee, but it is possible.
For very simple shipments — a small parcel from a supplier you've used many times, with clear documentation and no regulatory complications — some importers handle the basics themselves and only bring in a broker when something is held up. This works until it doesn't.
When you need one immediately
If your goods are currently held at customs, you need a broker now. The longer goods sit at a customs point, the more complicated the situation can become — and the more you may owe in storage fees. A broker can step in mid-process if you provide a power of attorney and the existing documentation.
If you're importing a product category you haven't dealt with before, getting a broker involved before the goods ship is considerably cheaper than dealing with the consequences of a declaration error after they arrive.
The paperwork for most imports is straightforward. The problem is that importers often don't know which parts are the tricky ones until after the goods are stuck at the border.
That's roughly the situation. If you have a specific question about your import or want to discuss a shipment, get in touch.
