There is no "safer". Some will tell you DHL is safer, and some will swear by EMS. But the fact is that ANY package coming into the US can be inspected by Customs REGARDLESS of who the carrier is.
If they find counterfeit merchandise, drugs, or any other illegal items, the package will be seized. What happens after that depends on what was in the package. If it were, for example, a few box sets of ⊗⊗⊗⊗ DVD's, you will get a letter in the mail. If it was 10,000 Vicodin pills, then I suggest that you MOVE - QUICKLY!
Here is the thing.... A few years ago, it was easy to order counterfeits, rarely was anything ever seized. It is now much harder to get such items through - with ANY carrier. Of course they cannot look at EVERYTHING, but don't believe anyone who tells you it is "safe" because that would be a lie.
If your business plan involves anything illegal, I seriously urge you to reconsider. There are PLENTY of legitimate things you can bring in and make a profit on. No, not 300%+ but those profits are short lived.
