Is Clonazepam legal in Taiwan?

Also known as: klonopin

Legal status

Category 4 narcotic (第四級毒品) under Taiwan's Narcotics Hazard Prevention Act (毒品危害防制條例), named at 附表四第12項「氯硝西泮（可那氮平、氯硝氮平）（Clonazepam）」. Clonazepam is Category 4, but the closely related meclonazepam is a tier higher at 附表三第246項. The methyl group is the whole of the difference between the two grades. The model: the four grades and their anchor substances are in the Act itself, article 2(2) reading 「毒品依其成癮性、濫用性及對社會危害性，分為四級，其品項如下」, and the full item lists are the Act's own four schedules, 附表一 to 附表四. The power to change them is delegated. Article 2(3) reads 「前項毒品之分級及品項，由法務部會同衛生福利部組成審議委員會，每三個月定期檢討，審議委員會並得將具有成癮性、濫用性、對社會危害性之虞之麻醉藥品與其製品、影響精神物質與其製品及與該等藥品、物質或製品具有類似化學結構之物質進行審議，並經審議通過後，報由行政院公告調整、增減之，並送請立法院查照」, a review committee of the justice and health ministries reviewing every three months, adjustment by Executive Yuan announcement, reported to the Legislative Yuan. The Act was last amended 4 May 2022. The list was last amended by the Executive Yuan announcement of 25 June 2026, in force 27 June 2026, which moved etomidate and eight related compounds from Category 2 up to Category 1.

Consequences if caught

Capital exposure: none. Article 4(4) punishes manufacture, transport or sale of a Category 4 narcotic by five to twelve years, with a fine of up to NT$5 million. Article 5(4) punishes possession with intent to sell by one to seven years. Use and simple possession are not crimes at this tier: article 11-1(2) makes holding or using a Category 4 narcotic without proper reason an administrative fine of NT$10,000 to NT$50,000 plus four to eight hours of drug hazard education. Article 11(6) turns possession criminal at 5 grammes pure weight, up to one year. Article 9(1) increases the penalty by up to one half where an adult sells to a minor, and article 9(2) does the same where the buyer is known to be pregnant. Article 19 confiscates the property used in an article 4 offence and, for an article 4 offence specifically, the vehicle, vessel or aircraft used. Article 8(4) is the provision that catches sharing. Transferring a Category 4 narcotic to another person carries up to one year, and article 8(5) increases the penalty by up to half where the quantity transferred exceeds a threshold the Executive Yuan sets. Neither reaches this substance, at any quantity, and the Category 4 tier is the furthest from them. Article 4(4) reads 「製造、運輸、販賣第四級毒品者，處五年以上十二年以下有期徒刑，得併科新臺幣五百萬元以下罰金」, five to twelve years, a fixed term with a ceiling. The public official aggravation in article 15(1) attaches death or life only to article 4(2) and article 6(1); for an article 4(4) offence its second sentence gives only 「加重其刑至二分之一」, an increase of up to one half, which cannot reach life from a twelve year ceiling. The one qualification is about the charge and not about this substance. Article 9(3) reads 「犯前五條之罪而混合二種以上之毒品者，適用其中最高級別毒品之法定刑，並加重其刑至二分之一」: where the offence involves a mixture of two or more graded narcotics, the statutory penalty of the highest grade among them governs the whole offence, with up to one half added. Holding this substance mixed with a Category 1 narcotic is therefore charged at the article 4(1) rate, but the capital exposure there is supplied by the Category 1 component and not by this one.

If prescribed or medical

Clonazepam is a licensed antiepileptic and anxiolytic dispensed as a Category 4 controlled drug.

Documentation

Carry a prescribed supply in its dispensed packaging with the prescription, which is the proper reason that keeps article 11-1 out of the way.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Taiwan’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
