While entering Indonesia, you’ll allowed to bring, other than your personal effects, up to 2 litres of alcohol, 100 grams of tobacco (or 200 cigarettes or 50 cigars), and a reasonable amount of perfume. You can bring in typewriters, computers and tape recorders (cars, too) but these must be declared, and you must take them out of the country when you leave. You can bring in (or take out) as much foreign currency as you want, but there’s a restriction as far as Indonesian Rupiahs are concerned: no more than Rp 50,000 may be exported or imported.
Indonesia prohibits the entry of certain items- and read this very carefully; some of them are unusual. You can’t bring in radios, TVs, anything printed in Chinese, and Chinese medicines. Arms and ammunition and narcotics are, obviously, not allowed. You’ll need prior approvals for importing videocassettes, movie films and the like, and quarantine permits are required for plants (including their by products) and animals.
