Pocket Knife import prohibited
Details
Pocket knives are prohibited in carry-on baggage on commercial flights worldwide. In checked baggage, most airlines permit them, and in most countries personal pocket knives are legal to own. However, the UK bans carrying any knife with a blade over. Enforcement in Thailand carries fines from THB 50,000 to THB 500,000 and imprisonment up to 10 years in aggravated cases under Customs Act B.E. 2560 s.242-244; Narcotics Act.
Leaving with this item
Pocket knives may be exported from Thailand in checked baggage; carry laws at the destination govern what you may do with them on arrival.
Practical advice
Do not bring pocket knife to this country. Penalties may be severe. If unsure, declare on arrival — declared goods at worst attract duty or surrender, while undeclared goods found in screening are seized and fined.
