The HS Commodity Classification of Fatty Acids and Their Salts and Esters
Fatty acids and their salts and esters involve a wide range of tax items in customs tax-related tests,and their classification is relatively complex.This paper explores and summarizes how to classify these three types of commodities,and provides a detailed analysis through infrared spectrum analysis,gas chromatography-mass spectrometry and other detection methods.These analyses are beneficial to provide clear operational procedures and judgment criteria for customs tax-related laboratory departments,improve the efficiency of testing and the accuracy of classification,and help relevant enterprises to understand and master the tax codes and rates,providing a reference for compliance declaration.
