NOTES ON DEFINITIONS AND REGULATIONS FOR COAL TRADED INTERNATIONALLY

摘要

Gross calorific values are generally used to identify varieties of coal in a commercial context. Net calorific values are more appropriate for inter-fuel analysis (please see General Notes and Definitions at the beginning of Part II). Starting on 1 January 1988, Australia, Japan and the European Community adopted the Harmonised Commodity Description and Coding System (HS) for classifying internationally traded commodities. Commodity codes used for classifying coking and steam coal are given for both the old and new systems.
