How do I minimize the chances of TSA agents confisticating liquids larger than 3 ounces?

  • I know as a fact that I've gotten liquids larger than 3 ounces through the TSA scanner systems (such as sunscreen). I was scolded one time for bringing a shampoo container, but I was still ultimately allowed to bring that container through.

    In any case, how often are liquids larger than 3 ounces ultimately confisticated, if I put them in a ziploc bag where they can be clearly seen?

    So to clarify, you're asking how to break the law?? My understanding is that it's a legal requirement that you don't take liquids larger than 3 ounces through. I am, however, not American, so am not certain on this.

    Arbitrarily imposed and poorly enforced TSA regulations are very far from "the law" -- the worst they'll do is confiscate the offending item.

    For the most part, the 3.4oz rule isn't strictly enforced, in the sense that they don't normally physically check ever single container you have to make sure that it's less than 3.4oz. If it's significantly larger than 3.4oz they will normally be able to see that on the X-ray, and will physically inspect it.

    As an example, I travel with a can of spray deodorant that is around 4oz, but is only labeled with "100g", where other cans of the same product are labeled as "4oz (100g)". To date, having gone through airport security probably over 100 times (incl 5 times in the past 3 days) I've had them manually inspect it exactly twice.

    So if what you're traveling with is close to 3.4oz, you're probably fine. However, if they decide to look at it, and it's over 3.4oz, then you'll almost certainly lose it. It's up to you whether it's worth the risk/cost of losing whatever it is you're trying to take through. If it's a 4oz tube of toothpaste it's a different answer than if it's a 5oz bottle of $200 perfume!

    Remark: 100g is a measure of mass, not volume. For instance, 100g of Plutonium occupy 0.17oz and 100g of flour occupy 5.7oz. So the label "100g" tells nothing about whether a container can go through TSA.

    @FedericoPoloni - agreed, but chances are the OP (@Doc) is misreading "100 ml" as "100 mg" as I haven't seen any spray deodorants bottles that are measured in grams.

    Many spray deodorants are labeled in grams. For example, https://amzn.to/2zgUNi9
