Seed is commercial production of seed, not seed for seeding, so I'm glad you highlighted that.
As to the rate for canola and soybean oil going into Japan, the tariff is 10.9 yen per kilogram—around $55 a tonne. It fluctuates depending on currency exchange rates. The tariff on seed is zero. So right away, you're taxed if you try to ship oil in, and it's cheaper to put the seed in. So that's what commerce does—it puts the seed in and then the Japanese crushers buy it and crush it over there. Corn oil was going in at 5 yen per kilogram, which is less than what soybean and canola oil are subjected to. For sunflower oil, it's 8.5 yen per kilogram. Those are tariff rates on a per-kilogram basis.
We'd like to see those tariff rates converted to ad valorem equivalency. Over time, if you change that to a percentage, the effect of the tariff fluctuates between 15% and 30% of the value of the oil product. It's driven by exchange rates. So you have this uncertainty in the tariff. It should be reduced if not eliminated, and if it is reduced, it should be converted to ad valorem instead of specific rates.
