Why Accounting Methods Matter
Drawback accounting methods determine how imports are matched to exports when you can’t (or don’t need to) track specific items. These methods provide a systematic approach to establishing which import entries support which export claims, particularly important for substitution drawback where physical tracking isn’t required.
It’s crucial to understand: drawback accounting methods have nothing to do with GAAP accounting or how you manage inventory for financial reporting purposes. They’re entirely separate systems used solely for customs drawback purposes.
Available Methods
CBP-approved drawback accounting methods include FIFO (First In, First Out)—exports are matched against the oldest qualifying imports first, LIFO (Last In, First Out)—exports are matched against the newest qualifying imports first, Low-to-High—exports are matched against the lowest-value qualifying imports first, and other approved methods for specific situations.
The method you choose affects which specific import entries are consumed by each export claim, which directly affects refund amounts when duty rates vary across entries.
Choosing the Right Method
Method selection should optimize your drawback recovery while remaining compliant with regulations. Consider your duty rate history—if early imports had lower duty rates than recent imports, LIFO may generate larger refunds. If earlier imports had higher rates (perhaps before exclusions were granted), FIFO may be preferable.
Once selected, the method must be applied consistently. You can’t cherry-pick which entries to claim against for each export—the accounting method determines matching systematically.
Documentation Requirements
Whatever method you choose, documentation must support the matching. Records should demonstrate how the method was applied, which imports were matched to which exports, running balances showing available import quantities, and that the method was applied consistently across claims.
Modern drawback software automates much of this tracking, but the underlying logic must be sound and auditable.
Method Changes
Changing drawback accounting methods is possible but requires care. You generally need to deplete existing inventory positions under the old method before switching, or establish clear demarcation between periods using different methods.
Method changes should be documented thoroughly, including the rationale for changing and how the transition was handled. CBP may question method changes that appear designed solely to maximize individual claims rather than reflecting operational realities.
