Trusting your supplier’s classification? It’s a ticking bomb for Customs & Export Compliance across EU, UK, and USA.

In Customs and Export Compliance, especially across the EU, UK, and USA, one of the most common yet costly mistakes is relying blindly on your supplier’s classification.
An HS code or export control number might feel like a simple box checked. But that’s far from the truth. Many customs professionals, importers, exporters, and consultants face significant risk when they accept secondhand classification without proper verification. It’s a risk that can lead to fines, delays, and legal trouble—avoidable if you understand the pitfalls.
