Strong search ability. According to my superficial experience, F5 fuel oil in the Middle East is higher than this standard, and CST 180 and CST380 in Singapore are close, but some of them do not meet, and M 100(75 and 95) in Russia, and others are small-scale trade. CST 180 and CST380 are mainly used to produce boiler fuel and marine fuel oil. QQ 1027796067, hope to discuss with each other.
