AI Summary

Recovery of Price Differential: supplier may claim undercharged amounts but generally cannot recover interest arising from its billing error.
Supplier may recover the price differential arising from an inadvertent undercharge by issuing a supplementary invoice and paying duty; however, interest incurred due to the billing error is generally not recoverable from the buyer. Before claiming recovery, verify the purchase order/agreement and any price variation clause, prepare a detailed annexure of affected invoices, and pursue remedies through commercial negotiations, formal communications, legal notice, or arbitration while maintaining tax compliance and documentation.
