1 Based on 2-digit code for Standard Classification of Transported Goods (SCTG).

2 Horizontal lines and color codes are used within the table to group the commodities. Commodities within the same group, or the same color code, cannot be determined to be different statistically from one another. However, from top to bottom, a change in grouping, or a change in color, denotes a statistical decrease in level of tonnage, based on statistical significance testing at the 95% confidence level.

3 NEC = not elsewhere classified.
