“We’re just using the same HS code we used before.” “Since the supplier provided the code, I didn’t think there would be any issues.”
These are comments we hear very often when consulting on imports. In fact, errors in HS codes are one of the most common causes of customs clearance issues, right alongside incomplete documentation.
Nevertheless, HS codes tend to be overlooked, often viewed as something that’s “set in stone once decided” or “merely a matter of detailed classification.”
However, from a practical perspective, errors in HS codes are not simply mistakes in selecting a number.
・Inability to determine tax liability ・Inability to determine if goods are subject to regulations ・Undermining the credibility of the entire documentation
These errors trigger a chain reaction of problems, creating a structure that ultimately leads to serious import issues.
In this article, we will examine why errors in HS codes become such a significant problem and why the same mistakes are repeated—not based on intuition, but by analyzing the underlying structural issues.
