Okay, the user wants me to translate "import fees" into Traditional Chinese. Let me check the rules again. The first rule says to translate all content into Traditional Chinese. The second rule states that if the content is already in Traditional Chinese, output it unchanged. The third rule is to provide only the translation result with no explanations.
So, "import fees" is in English. I need to translate it. The correct translation for "import fees" in Traditional Chinese is "進口費用". Let me confirm that. Yes, "進口" means import and "費用" means fees. So the translation should be "進口費用". I should make sure there's no explanation, just the translation. Alright, that's it.
