Answering &quot;Do you have anything to declare?&quot; to customs in the absence of any explanation of the question
<p>On some occasions, when a traveler goes through US customs, there are electronic self-serve kiosks or paper forms with detailed customs questions about what you are carrying (currency, goods, food, etc.), and there are statements warning about penalties for not answering truthfully.</p>
<p>On other occasions, there is none of the above, and no explanatory signs posted, and the customs officer simply asks, &quot;Do you have anything to declare?&quot; (this happened to me recently when traveling from a US territory to the US mainland) so it's not obvious what they are asking, or that there are penalties involved. Suppose somebody should have answered &quot;Yes&quot; but they answered &quot;No&quot; because they didn't understand the question, or they have never travelled before, or they didn't know or didn't remember all of the items that should be declared. In this case, it sounds like ignorance of the law could be a reasonable defense. Is it?</p>
<p>If customs wanted the question to be legally enforceable, in the absence of any accompanying written explanations, shouldn't they say something more like, &quot;Do you have anything to declare under US customs code, section blah blah blah? Not answering truthfully can carry penalties and fines. If you don't understand the question, please ask.&quot;</p>
<p><strong>Update:</strong></p>
<p>For those wondering where my customs interaction occurred, it was at the STX airport in St. Croix, US Virgin Islands (a US territory). It's an international airport, but most outbound flights are to the US mainland. Technically, travelers leaving USVI are already in the US, but air travelers leaving the territory have to exit through US customs and immigration. Possibly it's because the USVI's borders are extra-porous so they are monitoring for illegal immigrants, and/or because USVI has certain restrictions and duties for goods going to/from the US mainland.</p>
<p>US Customs and Border Protection in STX used to hand out Customs Declaration forms, so it was easy to understand what to declare. Now they just ask verbally, either in some detail (&quot;Are you carrying any food?&quot;) or as a broad question (&quot;Do you have anything to declare?&quot;).</p>

<p>The answer has two parts depending on how you get here. Airline answer: Any such question by a CBP officer is merely a last-chance option to supplement the response you gave on the <a href="https://www.cbp.gov/sites/default/files/documents/CBP%20Form%206059B%20English%20%28Sample%20Watermark%29.pdf" rel="noreferrer">declaration form</a>. The form asks a series of specific questions which are difficult to misunderstand (if you speak English), you say yes or no, and fill in applicable details. If you remember that you put an apple in your luggage, you can verbally amend the declaration. It is not necessary or practical to recite the statutory, regulatory and case law authority to ask these questions. As I recall, the electronic version asks the same questions. All versions of the form that I have encountered over the decades have included the perjury warning. If you had an alternative experience for you did not fill in a customs declaration form, that would be unusual, and a significant failure by the CBP officer(s).</p>
<p>Land-border answer: you are right. In this case (when no customs declaration form is filled out), they rely on every person's obligation to know and comply with the law. You are required to declare the $12,000 cash that you are bringing back, and you cannot plead &quot;I didn't know I had to declare that cash&quot;.</p>

<p>No.</p>
<p>I believe that is fundamental to many systems of law.</p>

<p>I would slightly amend some of the other answers here: ignorance of the law is <em>not</em> a defense, but it <em>can</em> be a mitigating factor in sentencing.  If you intended to follow the law but were unaware of something that a normal person might not know of, you could use that to sugggest a decrease (or elimination) of the penalty.  It doesn't mean you didn't commit the offense, but if you took no efforts to conceal (whatever it was) and it is sufficiently unusual that a person might reasonably not know about it needing to be declared, then a judge might go easier on you.  It is usually at their discretion, though, so certainly don't rely on it!</p>
<p>That said, particularly on an airline odds are you've been asked about all of the relevant things, and typically when there are common things people aren't thinking of, there will be signs - for example, when pot became legal in Canada a few weeks before I traveled there (not for that reason!), there were at least a dozen different places that signs were posted reminding travelers they shouldn't bring any pot back to the US, even if they're going to a pot-friendly state, as it's federally illegal.</p>
