There are at least two sides to this argument. I am very much of the remain view as frankly being part of a large trading block is best for the UK. I am involved in financing grwoing technology businesses and can absolutely see the benefits of being part of a larger community. I am of anglo-saxon origin, albeit of probably Hugoneot extraction but born to overseas, albeit all grandparents and mother were born in Britain. I have always held a British passport for the last 35 years (ie ever since I have had a passport) but everytime I renew it I have to justify being here. Frankly if I applied today I would n't get a British passport because the controls on British passports are very tight.
There is lots of shouting lets leave Europe with a hard BREXIT. Lets look at stalking as an example.
How it will affect Imports:
So Rifles and Shotguns - take a Tikka, Sako, Blaser, CZ, Beretta - all from the EU. Currently can be traded with no import tarriffs.
After Hard Brexit - 3.2% import duty, plus VAT at 20% -.
Other firearms and similar devices which operate by the firing of an explosive charge (for example, sporting shotguns and rifles, muzzle-loading firearms, Very pistols and other devices designed to project only signal flares, pistols and revolvers for firing blank ammunition, captive-bolt humane killers, line-throwing guns) - Trade Tariff - GOV.UK
Ammunition - ie RWS, Norma, Sako etc - 2.7% Import Duty plus VAT at 20% -
Bombs, grenades, torpedoes, mines, missiles and similar munitions of war and parts thereof; cartridges and other ammunition and projectiles and parts thereof, including shot and cartridge wads - Trade Tariff - GOV.UK
Optics - ie Sawarovski, Zeiss, Leica, Meopta etc - 4.2% Import Duty plus VAT at 20% -
Other instruments - Trade Tariff - GOV.UK
No bear in mind that the importer has to pay the tariffs and any VAT at time of import and before they are released from Customs (or have in place a customs bond or use a trade finance facility - these cost c2% per month for funds outstanding), so you will be adding further costs on here. Have a look at the markup currently on say a Remington in the US, versus the cost here, and start applying that to all the Sako's, Tikkas, Berretta's etc.
In terms of Exports:
The bulk of our venison is exported to the EU - Game meat is at 0% Tarrif -
Of game, other than of rabbits or hares - Trade Tariff - GOV.UK - so not making much difference there.
By the way sea fish and shell fish are subject to EU duties of 10 to 18% depending upon species - that's just added 10 to 18% to the cost of all the Scottish produced exports that go the EU.
Crustaceans, whether in shell or not, live, fresh, chilled, frozen, dried, salted or in brine; smoked crustaceans, whether in shell or not, whether or not cooked before or during the smoking process; crustaceans, in shell, cooked by steaming or by boiling in water, whether or not chilled, frozen, dried, salted or in brine; flours, meals and pellets of crustaceans, fit for human consumption - Trade Tariff - GOV.UK
I could go on, but most won't listen, but they will be the first to whinge when prices go up. Oh and if you live in Scotland we will all be taxed higher, so have less money to spend.
