Abstract: |
Two batches of refined palm kernel oil from Indonesia were imported at Zhangjiagang Port in Jiangsu Province. Their densities were found to have a significant positive deviation (false high). At the base point temperature (30 ℃), the density provided by the loading port was about 0.5% higher than that tested at the Customs laboratory; furthermore, the density-temperature coefficient of the oil used at loading port was only 0.000 287 353 t/(m3· ℃), which was much lower than that of vegetable oil used in China, 0.000 64 t/(m3· ℃). The differences resulted in significant mass shortage, damaging the legitimate rights and interests of the consignee. Suggestions to avoid the risk of mass shortage were then put forward in the present study. |
