Just be careful when importing from China using your suppliers shipping company, before I went out on mat leave I'd been trying to bail out a guy who bought some stuff that ended up stuck in Rotterdam for around 4 weeks, he was at the mercy of their shipping company until they had enough freight to fill the container and had an irate customer waiting on product here.
If you get a dedicated container you shouldn't have any such issue.
If your supplier pays the freight the onus is on them if it falls into the sea enroute too,
Also if you sign for goods without checking them, find they are damaged when you open the container you have no comeback so check before you touch the delivery docket - this drives drivers mental as they are always in a hurry so if you're expecting this you're less likely to sign your rights away.
Work off letters of credit and you should be fine,
