Welcome to the site, Polybius :)
dmdiscounts is perfectly right! The best thing you can do to minimize your liabilities down to zero is to NEVER source any brand name products in China. If they can produce replicas that look exactly like the real product, they can also produce fake authenticity documents/certificates to further lure you into buying from them.
Stay away from this supplier and from other Chinese suppliers offering brand name items.
What particular brands are you looking? Maybe we can help you search for suitable suppliers.
