Cross-Border Jurisdictional Protocol
Taiwan is not a party to the Hague Service Convention or any other treaty related to international service of judicial documents, a position rooted in its unique diplomatic status following the UN's 1971 recognition of the People's Republic of China. U.S. courts have found that because Taiwan does not prohibit service of process by mail, mailing the complaint to a defendant's Taiwan headquarters can satisfy FRCP 4(f)(2)(A), though formal Letters Rogatory remains the most defensible route for contested matters. One detail matters more here than in almost any other jurisdiction: translations must be into Traditional Chinese, not Simplified Chinese, which can be perceived as a slight given Taiwan's political relationship with mainland China.
Since Taiwan does not prohibit service of process by mail, we can arrange mail service to a corporate defendant's Taiwan headquarters where this fits the requesting court's own service rules.
Discuss mail service options →For the most defensible, treaty-independent channel, we prepare Letters Rogatory, noting Taiwan's domestic law requires service to be carried out by the clerk of Taiwan's court — a process that takes months either way.

Judicial Knowledge Base
No. Taiwan is not a party to the Hague Service Convention or any comparable treaty on international judicial document service, a position connected to its diplomatic status since the UN's 1971 shift in recognition to the People's Republic of China.
Generally yes for corporate defendants at their Taiwan headquarters — U.S. courts have found this satisfies FRCP 4(f)(2)(A) since Taiwan does not prohibit mail service, though this does not extend to serving a U.S. subsidiary in place of the parent.
Translations should be in Traditional Chinese; Simplified Chinese, associated with mainland China, can be perceived as a political slight in Taiwan.
No. It takes months to complete and Taiwan's domestic law separately requires that service be carried out by the clerk of Taiwan's court, making it no less cumbersome than the mail alternative in many cases.
Courts have found personal service by a private process server insufficient on its own for a foreign corporate defendant; a documented, court-recognized method such as mail to the company's headquarters or Letters Rogatory is generally required.
