Not long ago I finished a translation project related to international trade. At times I had real fun while translating. Why? Because customs seems to be that kind of service where everything, including translations, needs to be brought to some kind of a uniform standard. In reality, it's not always so (especially in the Russian-English non-native translations I came across). But I thought I'd put my discoveries here for future reference. As for those terms that have more than one variant of translation, you can always ask your client which option they prefer. Even if you are not a translator, these links may be very useful if you are learning English or Russian, especially for business. So check them out!
