Passengers carrying large quantities of powder in hand luggage, including protein powder, powdered cosmetics and other dry products, could face delays when passing through airport security. The warning comes as travellers are reminded that some everyday items can make it harder for security staff to see what is inside a bag during X-ray screening.
According to Government guidance, food and powders carried in hand luggage can obstruct images on airport security machines. This means passengers may have their bags searched manually, even if the items themselves are allowed on board.
What the rules say about powders
The Government advises travellers to pack these products in their hold luggage where possible to avoid unnecessary delays. There are also additional restrictions for passengers flying to the United States.
At Heathrow Airport, powders weighing more than 350g or measuring over 350ml are not permitted in cabin bags on flights to the US, although certain exemptions apply. These include medicines, baby powder and human ashes, which may still need additional screening.
US checks and liquid limits
The US Transportation Security Administration (TSA) also advises passengers carrying powder-like substances over 350ml, or 12oz, to expect additional checks. Containers may need to be opened and examined separately before passengers are allowed through security.
However, the rules are different for creams, pastes and sprays. Products such as toothpaste, moisturiser, hairspray and aerosol dry shampoo are classed as liquids rather than powders.
Check rules before flying
The amount passengers can carry depends on the airport they are departing from. For example, London Gatwick now allows liquids in individual containers of up to two litres, while London Luton continues to enforce a 100ml limit.
Passengers are therefore being advised to check the rules at their departure airport before packing. Anyone travelling with large containers of protein powder or similar products may find it easier to place them in checked baggage.
Keeping hand luggage organised can also help security officers inspect items more quickly if a bag is selected for additional screening. Travellers should remember that security staff have the final say on whether an item can pass through the checkpoint.
