Actually, it is rational, given, as you noted, the PRC level of quality control export.
With the raw product, you can control if it is actually as is stated, along with appropriate assays and continue with the next step until finished product.

PRC's standards are truly way off base and lacking in the following.
1. Genus and species identification - identity
2. Heavy metal screen. Lead is often seen is even herbal medicine tablets!
3. Solvent residue screen
4. Potency assay
5. Shelf life testing
6. Aflatoxin screening
