we just moved back to the US. we used an international company to pack and deliver door to door. they used very general terms for inventory list (kitchen items, toys, linens, office supplies, etc) also just put down what the majority of the box contents was, not every category. Our house full of stuff came through and was delivered to our home a mere 10 days after leaving the UK, by sea container, so there were no questions with customs. maybe it depends on the company you use...
