No, they are concerned if you bring in more than 500grams of meat. Poultry, charcuteriew, sausages are not counted as they are processed, i believe you can bring in 2kgs of sausages.
When my uncle went missing in the alps and presumed dead; my father found 7 Kgs in the cleaning bucket in the cupboard of his apartment.
Unfortunately and against my advise, my father sold all 7kgs three years ago and then on top of this also against my advise transfered the Swiss Francs on the sale to sterling (chf 2.4 to £1) and then on top of that he purchased an apartment in the UK as an investment to which he has not rented it to this day but is paying council tax and service charges on.
I would guess he has lost 80% of the value of the gold today on his transactions.
Now he will even have UK inheritance tax on his death on the apartment.
If you are planning to bring gold from the DRC, you are not the only one. The authorities are very vigilant with regards to DRC and you will have a hard time getting it in and out.
You will not be asked to fill in a form. Though one has currently to limbo under ever lowering bars to get into the US, Europe is quite open. Coming from another Shengen country you don't even show you passport.
There is no tax on bring money in. However, if it is suspected this is a result of tax evasion and/or theft and it is discovered in a random customers search at the green 'nothing to declare' lane, you may have to answer to the police. Likewise on leaving the US, when you and your hand luggage are scanned.
Strictly speaking your carry on baggage is limited to 5kgs. I have had mine weight at checking before now and told to either check it in or move stuff about. So that's only about $200,000 worth...
If one brings gold into CH, from a non-EU country ... what kind of proof is required to declare it as a personal jewellery (<10gms). Can one just walk out of the customs wearing it or in hand luggage.
Since gold is not taxed in Switzerland (its considred a currencie) i belive the same rules apply to you when bringing it into Switzerland as if you were bringing cash.
You will have to declare it, You might have to proof were it came from or receipts that you bought it but you WONT have to pay tax on it !
VERRY IMPORTENT: You WILL have to declare it to the US customs upon leaving America, otherwise thy have the right to confiscate it...
But I plan to buy some personal jewellery in UAE and bring-into CH.
From what I read in the net, I have to pay 2.5% tax on gold imported. What is not clear to me is whether 300 CHF personal import allowance limit is applicable to personal jewellery or not.
