This study examines the exchange patterns of burial vessels excavated from bungumyo tombs in the Yeongsan River basin which were identified through analysis using a portable X-ray fluorescence spectrometer (pXRF). Two main issues are addressed. Firstly, wares thought to have been imported, namely, sueki, were analyzed to determine whether they were imported or locally imitated. Most of the sueki analyzed in this study differed in chemical composition from locally produced ceramics, indicating that they were likely imported, while one sample may have been produced locally. Additionally, some ceramics that are not traditionally classified as imported wares were found to have been produced outside of the Yeongsan River basin. Secondly, exchange patterns of burial vessels within the Yeongsan River basin were examined through comparisons of chemical compositions for artifacts from different archaeological sites. Results showed that even within a single site, variation in chemical composition of burial vessels was significant and did not cluster according to its location of burial. This contrasts with the clear clustering observed in the analysis of utilitarian pottery excavated from settlement sites. This may indicate that pottery produced at multiple locations was placed within a single burial site and pottery used as burial vessels were frequently exchanged between sites in the Yeongsan River basin. It is believed that these items were used as funeral offerings brought by a variety of groups that participated in funerary rituals.
