If exported for repairs under warranty and value increased abroad
Applies to US goods exported for alterations/repairs with duty only on repair costs, rather than full value exemption under 9801.
If substantial US-origin container imported holding the transformer
Covers substantial containers of US manufacture returned separately, per subchapter I notes, rather than the transformer itself.
