We use steel tubing that's supplied by mills. We don't buy through distributors. We get it directly from the steel mill that manufactures it. That supply is fairly limited around the world. There are some suppliers in India, Asia and South America. But once again, when you're looking at three to six months' lead time on getting the steel from the mill, to change suppliers is over a one-year process.
Naturally, being in a situation where we had retaliatory tariffs, we were facing a 12- to 18-month period before being able to get new sources of supply, which would have put us in a really bad situation.
