As I recall none of the Japanese lift companies selling in North America were members of the ITA until about 1983 and at that time Datsun (Nissan out of Mayfield, Ky) was the #1 importer and the ITA reported sales was in the 100K area in all 5 classes - 140k unit sales was a record back. Marketing studies I was involved in stated that Japanese products represented about 30% of all the new equipment sales not counting the "grey market" imports. Around 1985 Hyster claimed an anti-dumping suit against the Japanese companies end result was an anti dumping duty was imposed from about 10% to 40% (% varied by manufacturer) on trucks up to 15.5 K capacity. Shortly after that the Japanese companies opened "assembly" operations in the US.
