Dont really agree with the statement that one shouldnt get clever with HMCE...
Im all for it, as long as you are WITHIN the law, then why not try it on?
They take the p*** with legit traders on a daily basis, becuase they can, so the same holds true in reverse, if you are 200% sure that your not breaking any laws go for it, watch them squirm and run around like headless chickens!
They can try and try and try, BUT it stands...if you are within the law they can huff and puff but they cant blow your house down.
Ive had many many instances where HMCE have either wanted to inspect my goods, or they cast doubt over the paperwork, the goods or just felt like being gits, BUT every single time ive come down on them as hard as I possibly can (but in a nice way, never rant and rave, always be polite, to the point and make them belive they are important, and busy etc etc) and not once have they refused to clear goods at an accpetable pace.
Alot has been said in many places that HMCE are a law within the law, this is true and false, just because they are HMCE does not mean they are not answerable to anyone...
Maybe im more confrontational with regards to HMCE than others, but they certainly dont do me any favours...
