Without going into too much detail .... Since this is a public forum ....
I was for a time, involved with a chap who said (though I have no hard evidence) that he was able to import goods without attracting 'attention' from anyone save himself on delivery. Since I was aware of his enterprise, I can say (subject to his telling the truth, which to be honest he seldom did) his orders were of the value of circa £1000 a month. Not a lot by way of sales in a large company, but quite a reasonable amount of business for a one-man band, and a single purchaser.
Referring back to ITAR, there came a time when not speaking the absolute truth became an issue which, and American retailer (not the same one) informed me that to NOT tell the truth, could land you with a 7 year jail sentence. Mindful margins in the US are significantly smaller than in the UK (say 30% vs 10%), there wasn't a great incentive to lie, unless an order with a value of 6 figures was made, and in those circumstances a completely different set of people would be involved. (Federal Departments looking at money laundering, for example.)
The Chinese on the other hand, are interested in getting foreign currency landed on China, so it can be spent buying up the world. (Which is exactly what they are doing.) The Chinese don't give a monkey's about UK taxes, (or indeed UK copyrights ....) Since I can't find my sintered diamond drills, I will be replacing them from China from where I will be shipped at least two items, for probably less than the postage. How is this possible? Ask the British Steel industry...
You obviously haven't spent enough time, learning to mimic the girls on the Victoria's Secret catwalk.... The secret (if you'll excuse the lazy pun) is to walk with one foot overstepping the other. To explain another way; Imagine your line of direction with two parallel lines perhaps 3 inches apart. The line on the right is for your left foot, the line on the left for your right foot. As you walk, left over-steps right, then right over-steps left. Bow-leggedness is hidden. I've not mastered it myself, and I expect too look like I need two new hips if ever I do, but it works for very highly paid models.
