What happens if nothing changes
In customs, a wrong heading or under-valuation is recovered as differential duty with interest and penalty, the goods can be detained or confiscated, and - because the same treatment repeats on every consignment - the exposure multiplies across the entire import history until an audit or SIIB investigation surfaces it. A denied FTA benefit or a mis-read exemption turns an expected margin into a demand. Doing nothing means running the import stream on classifications taken once and never re-tested against the current tariff and notifications.
