Tougher screening measures at Australian airports will apply to passengers packing certain powders in carry-on luggage on international flights from June 30, reported News Corp.
Passengers taking powders classified as “inorganic” cannot take more than 350 grams (or 350 millilitres).“Inorganic” powders include salt, salt scrub, sand, some talcum powders, powdered detergent and cleaning cleaning products.
No restrictions will be placed on “organic” powders, such as baby formula, protein powder, coffee, spices and Epsom salts.
Importantly, the restriction will be based on total container volume rather than amount of powder. This means that passengers will not be able to tip inorganic powders out to fall under the 350 gram threshold.
