Be aware of restrictions if you intend to carry any of the following articles and substances:
|Aerosols||Medicinal or toilet articles including aerosols may be carried in carry-on baggage. The rules on package sizes for liquids in carry-on baggage apply to aerosols too. Checked baggage may also contain aerosols for sports or household use, if they are non-flammable, non-toxic and non-corrosive. The aerosol vents must be covered by a cap or other protection to prevent inadvertent release of content. The total net quantity of all such articles must not exceed 2 kg or 2 litres, and the net quantity of each single article must not exceed 0.5 kg or 0.5 litres.|
|Alcoholic beverages||Alcoholic beverages in their retail containers, with an alcoholic content of more than 24% but no more than 70% by volume, may be carried either in carry-on baggage or checked baggage with a total net quantity not exceeding 5 litres per person, in containers with a maximum volume of 5 litres. See also the restrictions on the carriage of liquids and customs regulations.|
|Art supplies||Art colours packed in tubes are generally inert and thus may be carried either in carry-on baggage or in checked baggage, subject to the restrictions on the carriage of liquids. Solvents for art colours are often hazardous flammable liquids and as such may not be carried. It should also be noted that rags soaked in linseed oil may react with oxygen, heat up and self-ignite. For this reason, linseed oil is considered a hazardous substance and is forbidden from aircraft.|
|Batteries (wet)||Forbidden (corrosive).|
|Batteries and cells (for consumer electronics)||Consumer electronics for the passenger’s own use may be carried either in carry-on baggage or in checked baggage. Lithium metal or lithium ion batteries or cells may only be carried if installed in a consumer electronics device, either in carry-on baggage or in checked baggage; it is recommended that these be carried in carry-on baggage. Spare batteries or cells may only be carried in carry-on baggage and must be protected so as to prevent short circuits. A passenger may carry no more than two spare lithium batteries or cells. The lithium content of all batteries and cells carried must not exceed 2 g in weight or 100Wh in energy content.|
A hydrogen peroxide solution for bleaching hair may be carried in carry-on baggage (subject to the limitations on carriage of liquids) or checked baggage in a well-sealed container if the hydrogen peroxide content of the solution is less than 8%.
|Camping stoves||Flammable liquids and gases (canisters) for camping stoves, e.g. Trangia, are completely forbidden. The camping stove itself may be carried if carefully emptied and cleaned. The wick must be cleaned and dried so as to remove any traces of fuel.|
|Deodorants||Roll-on deodorants are classified as liquids and are therefore subject to the restrictions on the carriage of liquids. Stick deodorants are not liquids.|
|Diving equipment||This equipment may include gas cylinders, which are not allowed if they contain pressurised gas. Empty tanks (pressure gauge reads zero) may be carried. This equipment may also contain high-intensity diving lamps, which can generate extreme heat if operated in air. In order for such a lamp to be carried safely, the bulb or battery must be removed and the terminals of the battery protected to prevent a short circuit.|
|Firearms and ammunition||Firearms for sport or hunting may only be carried in checked baggage, and only with specific permission from the airline. Firearms must be unloaded and packed in a sturdy package. Securely boxed cartridges may be carried in checked baggage only in quantities not exceeding 5 kg gross per passenger. The ammunition may not include explosive bullets or incendiary bullets, and their classification must be 1.4S and their UN number either UN 0012 or UN 0014.|
|Fireworks||Carriage of fireworks, including sparklers, is completely forbidden.|
|Fishing gear||Fishing gear (tackle boxes containing hooks) must be carried in checked baggage. Lures with hooks less than 6 cm in length may be carried in carry-on baggage.|
|Floorball sticks||May be carried in checked baggage.|
|Gas weapons||Forbidden (gases). Carrying replica guns in carry-on baggage is also forbidden.|
|Gas cylinders||Forbidden (gases). See also Diving equipment and Life jackets.|
|Hair curler||Line-powered hair curlers may be carried either in carry-on baggage or in checked baggage. One catalytic hair curler containing butane gas (container) may be carried, provided that the safety cover is securely fitted over the heating element. No refills may be carried, however. A hair curler with a butane container may be carried either in carry-on baggage or checked baggage.|
|Hair spray||See Aerosols.|
|Ice skates||May be carried in checked baggage.|
|Insect repellents (applied to the skin)||Insect repellents applied to the skin may be carried in carry-on baggage or checked baggage on the same conditions as for medicinal or toilet articles.
|Insecticides||Carriage of substances intended for killing insects (aerosols and liquids not intended to be applied to the skin) is completely forbidden because they are toxic and often flammable.|
|Insulin needles, insulin pump||Medicines and medical equipment required by a passenger for the care of his/her condition during the flight may be carried in carry-on baggage.|
|Iron (for clothes)||May be carried in checked baggage.|
|Kitchenware (frying pans, etc.)||May be carried in checked baggage.|
|Knitting needles||Knitting needles made of any material may be carried in checked baggage. However, only plastic or wooden knitting needles or crocheting hooks may be carried in carry-on baggage.|
|Life jacket, self-inflating with carbon dioxide canister||A self-inflating life jacket fitted with no more than two small canisters of carbon dioxide or other class 2.2 gas (non-inflammable, non-toxic) may be carried with permission from the airline. The life jacket may be carried in carry-on baggage, checked baggage or on the passenger's person (in a handbag or pocket). Not more than two refills may be carried with the life jacket.|
|Lighters and matches||Only one box of matches or one cigarette lighter is allowed for the passenger’s own use and on the passenger’s person, e.g. in a pocket or a handbag. Highly flammable ‘strike anywhere’ matches are completely forbidden. Matches and lighters must not be carried in carry-on baggage or checked baggage. Lighters containing unabsorbed liquid fuel (other than butane gas), containers of lighter fuel and lighter refills are completely forbidden. Any other liquid fuel than butane gas must be absorbed in another substance to be allowed. For the purposes of this rule, a ‘cigarette lighter’ means a small-size lighter such as is commonly sold in grocery stores, emitting gas at a low pressure and burning with a candle-like flame.
NOTE! Lighters emitting gas at a high pressure and producing a very hot flame are completely forbidden from aircraft. These include lighters designed for cigars, pocket torches and jet flame lighters. The emission of the gas causes an audible rushing sound.
|Lighter fluid||Forbidden (flammable liquid).|
|Medicines||All medicines that the passenger needs during the flight may be carried in carry-on baggage. Medicines in liquid form must be presented at the security check.|
|Oxygen or air bottles||Small bottles of oxygen or air for medicinal purposes only may be carried with the specific permission of the airline, either in carry-on baggage or in checked baggage. By contrast, for instance, carriage of gas cylinders used as diving equipment is forbidden unless the cylinders are emptied.|
|Paints||Forbidden if they contain dangerous substances (e.g. flammable liquids or toxins).|
|Photographic films and video recordings||May be carried either in carry-on baggage or in checked baggage. Baggage screening devices used in Finland do not damage photographic films or video recordings. Other countries may use different equipment, however, so it is recommended that articles of this kind are carried in carry-on baggage.|
|Roller skates||May be carried in checked baggage.|
|Shaving equipment||Loose razor blades or razor knives may not be carried in carry-on baggage. A razor blade is allowed in carry-on baggage only if permanently attached to a plastic razor blade holder.|
|Skateboard||May be carried in checked baggage.|
|Ski waxes and wax removers||Solid ski waxes and klisters may be carried either in carry-on baggage or in checked baggage. NOTE! Ski waxes containing fluorides are forbidden. Ski waxes with the word ‘flammable’ or ‘inflammable’ on their label are completely forbidden. For ski waxes in aerosol form, see Aerosols. Most wax removers are flammable liquids and as such completely forbidden.|
|Smoke detectors||May be carried either in carry-on baggage or in checked baggage.|
|Solvents and adhesives||Forbidden if they contain dangerous substances (e.g. flammable liquids).|
|Tinder box||May be carried in checked baggage if protected so that it cannot accidentally produce sparks (stone and metal surfaces separated).|
|Toy guns||May be carried in checked baggage.|
|Trangia||See Camping stoves.|
|Umbrella||May be carried either in carry-on baggage or in checked baggage.|
|Walking poles||May be carried in checked baggage.|
|Washing powders||Detergents in powder form for the passenger’s own use may be carried in carry-on baggage or checked baggage if carefully packed.
