Customs rules differ by country; check your own customs authority before you travel. Pick your country to put it at the top.
Note 1: Hong Kong Customs: travellers aged 18 or above may bring 1 litre of alcoholic liquor above 30% ABV (at 20°C) duty-free for personal use; Hong Kong ID card holders must have been outside Hong Kong for 24 hours or more. Hong Kong only taxes liquor above 30% ABV, so sake and other drinks at 30% or less aren't dutiable.
Note 2: Customs Administration, Ministry of Finance (Taiwan): from January 25, 2025 the personal duty-free alcohol limit rose from 1L to 1.5L, with no limit on the number of bottles; only travellers aged 18 or older may bring alcohol. Use the red channel to declare and pay tax on any excess.
Note 3: Singapore Customs: travellers aged 18 or older who spent at least 48 hours outside Singapore and are not arriving from Malaysia may choose one combination: 1L spirits + 1L wine, 1L spirits + 1L beer, 1L wine + 1L beer, 2L wine, or 2L beer. Duty and GST apply to anything over, and more than 10 litres needs a Customs permit.
