How much are you paying for container or LCL shipping from alibaba ?

My product ideas are like 3 lbs each, and thus air shipping would be too expensive.

However, freightos quotes me to NJ 4000$/ full 20ft container, and thus i would need to buy like 40k worth of inventory to make it pay off to fill up the container or no?

LCL is also expensive, 1 pallet seems to cost like 1500 dollars, making it more sense to fill a container or no ?
