[ASOIAF] What exactly did Davos (and other smugglers) smuggle?

Aside from onions, of course.

Davos was renowned as one of the most infamous smugglers in the world prior to entering into Stannis’s service. But what exactly did he smuggle? Westeros does not seem to have restrictive laws on trade and there is no real reference to a black market for prohibited goods/contraband (nor is there is a suggestion that many goods are outlawed). So what exactly was he smuggling?

There are reasons to smuggle besides moving prohibited goods. He could have been smuggling stolen goods, working with pirates to sell their loot. Or he could have just been avoiding paying various taxes and berthing fees.
