[FuriouslyAdrift]

We've doubled (or more) in headcount. Mostly in the 'special projects' area (complex shippers, partitions, pallets, parts movers, etc) and truck drivers (we have our own trucking company)

Our prices are primarily pegged to what brown paper is (used to make corrugated) which ebbs and flows. Our prices were affected a little because a lot of pulp and raw material comes from Canada (they sell soft wood incredibly cheap... it's actually been a point of contention in our treaty for decades) but the cost change has been fairly slight (close to inflation).

Labor prices have gone up a decent amount and so has health care. We've found savings in increased efficiency due to scaling up production (there are some big fixed costs wrt machinery that becomes a smaller piece of the pie with increased production).

Nobody imports boxes... cost of transport is more than the product which is why almost all box makers have regional plants.
