that in normal times you could expect about 2-6 weeks for the ship to make it. Two or 3 might be for a real optimum situation of speed, weather etc. That's in normal times and with disruptions to normal workflows, raw material supplies, manufacturing schedules, equipment/labor availability etc. it can be a real backlog. Look at what happened with new vehicles during the recovery from Covid lockdown where vehicles could only be partially assembled because this component or that was backlogged at a supplier because of supply of labor/materials issues.
No the stuff typically is all lead-time dependent and planned out accordingly. Most manufacturing doesn't like to spend money on big warehousing operations for finished product and they try to have a handle on planning to ship what is made within a short time. So when things like this happen they stop production since they don't know when this will end and the lack of available warehousing and/or not wanting to add costs for warehousing to their overhead.
So some things that are in inventory can ship but it screws the schedules up, backs up the replacement production and things that are seasonal can really be screwed up if this goes for very long. Items in gift shops for example are usually ordered around this time for delivery in the Fall. But with owners of gift shops here being uncertain about price due to tariffs, timeliness of delivery etc. they are hesitant to order. Worst thing for them is to spend a huge amount on orders for the Christmas shopping season that mostly don't arrive until January for example.
Also for most businesses that are needing to order things now the question is the uncertainty of the timing of the tariffs and are they on or off because if they order now and the production does come in a couple of months are they paying nearly double for the product and a competitor who waits a couple of months is paying way less and can then kill them on price.
So the uncertainty of it all makes people pull back and once that starts it's a negative feedback loop of consequences.
