I found the import restriction for Germanium Sesquioxide you referred to, but it appears to be cancelled. Please Explain.

The import restriction against Germanium Sesquioxide has not been cancelled. It clearly states that an earlier alert issued in 1988 was cancelled, for the purpose of revision, with the simultaneous issuance of another in 1995. This import alert further states that germanium material can be seized if the intended purpose is for human consumption and lists various names under which someone may attempt to bring ingestible germanium into the country. In cases like this, a simple LD 50 is not considered sufficient evidence in support of lifting the import restrictions. Designed Nutritional reaffirms its earlier position that any US importer of Germanium Sesquioxide is violating import restrictions that prevent the product from entering legally. http://www.fda.gov/ora/fiars/ora_import_ia5407.html.
