(a) Authority. All claims are subject to verification by CBP.

(b) Method. CBP personnel will verify compliance with the law and this part, the accuracy of the related general manufacturing drawback ruling or specific manufacturing drawback ruling (as applicable), and the selected drawback claims. Verification may include an examination of all records relating to the transaction(s).

If verification of a drawback claim filed under a general manufacturing drawback ruling (see §190.7) reveals errors or deficiencies in a general manufacturing drawback ruling, the letter of notification of intent to operate under the general manufacturing drawback ruling, or the acknowledgment of the letter of notification of intent, the verifying CBP official will promptly inform CBP Headquarters (Attention: Entry Process and Duty Refunds Branch, Regulations and Rulings, Office of Trade).
