In my experience of these things, a lot depends on the courier. Royal Mail never seem to bother, while some couriers see it as a chance to charge a £10 (or £11 in your case) fee to collect and pay the import duty. For them, it's just income maximisation. At least with something as expensive as BAIB, you probably don't mind paying it that much - in the early days of Amazon.com, I "imported" a couple of CDs with a total value of pennies over the £18 limit in force - the import duty and VAT was about 90p, while the courier charged £10 for collecting it. At least the guy who came to the door had the good grace to be embarrassed ...
