Two different questions. Airport security screening (TSA/CATSA — can it go through the checkpoint?) is separate from customs (may it enter the country at all?). This page covers customs after arrival in Thailand; for checkpoint rules, see the item guides.
Duty-free allowances
Personal exemptions for arriving travellers: 200 cigarettes or 250 grams of cigars or smoking tobacco; 1 liter of spirituous liquor. There is NO duty-free exemption for cigarettes or liquor purchased at airport terminal duty-free shops upon arrival. DISCREPANCY PROTOCOL NOTE: Thai Customs passenger guidelines verify a 20,000 baht personal-effects allowance for reasonable personal belongings; however, the official Thailand.GO.TH portal checklist also lists a 10,000 baht ceiling for non-commercial gifts and personal items. As both figures originate from official Government of Thailand sources, conservative planning advises adhering to the lower 10,000 baht threshold.
