Customs — Duty Optimization (Opportunity Cost)

Activate when: an importer has recurring, material duty spend; evaluating FTZ, duty drawback, first-sale valuation, bonded warehouse, or FTA use; 'are we leaving duty savings on the table?'. Do NOT activate when: de minimis / trivial duty where program cost exceeds benefit.

Industry front door for opportunity-cost. Adds domain triggers, example, packs only. Parent Process unchanged. Not legal advice. Each program has strict eligibility; verify with counsel/CBP before relying on savings.

Why this variant

The parent opportunity-cost measures the value of the best foregone alternative. Every duty dollar paid when a lawful program would have avoided/deferred it is a foregone saving. This surfaces those foregone alternatives and sizes them against setup cost.

Domain inputs → parent's Process

Enumerate lawful alternatives and their net value vs status quo:

• Duty drawback: refund on duties for re-exported/destroyed goods (up to 99%).
• Foreign-Trade Zone (FTZ): defer/reduce/eliminate duty; inverted-tariff benefit.
• First-sale valuation: dutiable value = earlier bona fide sale price in multi-tier transactions.
• FTA/preference (see USMCA variant), bonded warehouse (deferral).
• Weigh each program's admin/setup cost; opportunity cost = savings foregone by not adopting the best-fit one.

Worked example

Importer pays $800k/yr duty, re-exports ~30% of goods. → Foregone saving: drawback could refund 99% on the re-exported portion ($240k base) — far exceeding program setup. Not filing drawback is a recurring opportunity cost. FTZ may add inverted-tariff savings on the domestic portion.

Compliance anchors

• 19 U.S.C. 1313 (drawback); FTZ Act / 19 CFR 146; first-sale (Nissho Iwai); bonded warehouse 19 CFR 19.

Packs

• Broker/advisory: annual duty-spend audit → program-fit shortlist with net-savings sizing.
• Enterprise importer: FTZ feasibility + drawback recovery program.

Red flags

• Paying recurring duty with no program review.
• Assuming programs are "too complex" without sizing the foregone savings.
• First-sale claimed without qualifying multi-tier documentation.

Verification

• Applicable programs enumerated with net savings sized
• Setup/admin cost weighed against savings
• Eligibility documentation feasible for the chosen program
• Best-fit program recommended vs status-quo duty
