"The North had three times as many people and four times as many free people as well as a colder climate. It’s likely that they imported more coffee and clothing/textiles and other goods..."

Well, they didn't.

During 1860 the imports of the South were valued at $331 million; those of the North at $31 million.

Data for imports and tariffs collected for the year just prior to secession (July 1, 1859 to June 30, 1860, inclusive) is provided in the Annual Report of the Chamber of Commerce of the State of New York, for the Year 1860-61 (New York: John Amerman, 1861), 57-66. I’ve uploaded a PDF copy of the relevant pages here. The first two pages include imports that were not tariffed; in case anyone was wondering, manures and guano were duty-free.

In summary, during that year the Port of New York took in $233.7M, of which $203.4M were subject to tariffs ranging from 4 to 30%. During that same period, all other U.S. ports combined received $128.5M in imports, of which $76.5M was subject to tariff. So the Port of New York, by itself, handled almost two-thirds (64.5%) of the value of all U.S. imports, and almost three-quarters (72.7%) of the value of all tariffed imports

It's very unlikely that most of those imports made their way South.
