In the United States, there are no import duties on computers or on computer components.[1] But there are no duties on assembled computers or on computer components entering the United Kingdom either, so far as I can tell. Assembled computers are listed under heading 8471 of the Harmonized Tariff Schedule, which is used by all trading nations. (They are referred to as "automatic data-processing machines"; the terminology and categories are all quite archaic.) The UK imposes no import duty on computers of any type.[2] Parts and accessories "suitable for use solely or principally with" computers are listed under heading 8473.30 and likewise can enter the UK duty-free.[3] It's possible that some required components are listed elsewhere in the HTS and that those are not duty-free. But that seems unlikely; almost everything in Chapters 84 & 85, which cover all electronics, can enter the UK free of duties. I'm not familiar enough with the UK tariff regime to know whether there are other considerations beyond the base duty rate. (But it doesn't look like it; the relevant Acts of Parliament setting duties for each class of good are noted on the BusinessLink site linked below.) So I have no idea what import tariffs Raspberry Pi need (or think they need) to pay. It certainly doesn't look like the UK has some screwy import regime that penalizes firms wanting to assemble computers there. 1. So long as the goods' country of origin has "most favored nation" status. This means, essentially, that it has normal trade relations with the United States. That includes all members of the World Trade Organization. 2. http://tariff.businesslink.gov.uk/tariff-bl/export/heading.html?export=false&from=list&id=8471&simulationDate=10/01/12 http://tariff.businesslink.gov.uk/tariff-bl/export/heading.h... 3. http://tariff.businesslink.gov.uk/tariff-bl/export/heading.html?export=false&from=list&id=8473&simulationDate=10/01/12 http://tariff.businesslink.gov.uk/tariff-bl/export/heading.h...
