Regional interfinishes are held once in a year by the member countries except the year in which Interfinish World Congress takes place. The concept of regional meetings was not considered necessary in the early days when most member countries were in Europe, but when membership especially in the the Far East increased the position was quite different. The first Interfinish Congress held in anAsian countryat Kyoto in 1980 generated a record attendance of over 600 persons and even an immediate reprint of the conference volume! Consequently, a regional Asia-Pacific Interfinish wasproposed by Australia and the first was held in Hobart, Tasmania in 1986.Since then they have been held very successfully at four year intervals between world congresses. The early venues have been as follows
| 1 | 1986 | Hobart |
| 2 | 1990 | Singapore |
| 3 | 1994 | Melbourne |
| 6 | 1964 | London |
| 4 | 1998 | Seoul |
Similar events have been initiated by Brazil, following the Sao Paulo Interfinish in 1992, for South American countries and in India for SE Asia. For example:
| 1997 | IMFCONG in Mumbai |
| 1997 | Latin American Interfinish ‘Ebrats 97’ in Sao Paulo |
| 2015 | Euro Interfinish in Milan |
| 2018 | APAC Interfinish, 2018. Shanghai, China |
| 2023 | ICSE 2023- Regional Interfinish , Busan, Korea |
| 2024 | ISF 2024 - Regional Interfinish, Delhi-NCR, India |
The future of the IUSF seems assured as it is serving a vital purpose for a highly active and important sector of manufacturing industry.
