Traveling with less than 12 oz / 350 ml / 340 grams does not have any special restrictions.

Can You Take Flour In Hand Luggage?

You can bring flour in carry-on baggage. In fact, it’s safe to do so, especially for small quantities. 

There are no limits to the amount of powder you can bring in your carry-on luggage.

The only thing you should consider is your airline’s carry-on luggage size and weight restrictions.

Taking a large quantity inside your checked bag will also save you space for carry-on.

But make sure that you stay within your airline’s checked baggage allowance to avoid additional fees.

The TSA might open your suitcase for extra inspection, so you should ensure your flour is well-protected and fits securely in your bag to avoid spills.
