Example use cases
Unused merchandise export refund estimate

Manufacturing drawback after production export
“My company paid $45,000 in duties on raw materials and incorporated 100% of them into finished goods we exported — estimate our manufacturing drawback refund and tell me the filing deadlines.”
Rejected goods destruction refund
“We imported goods, paid $30,000 in duties, but 60% were rejected and destroyed — what refund can we expect under a rejected merchandise drawback claim?”

Endpoint
GEThttps://x402-niche-briefs.fly.dev/v1/duty-drawback-estimator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, legally-grounded estimate of US customs duty drawback eligibility under 19 USC 1313 without engaging a customs broker. It is ideal for pre-filing triage, CFO reporting, or automated trade compliance workflows where a fast approximation of 99% duty recovery is needed. Prefer this over generic tax calculators because it understands the four specific drawback types and their distinct legal provisions and deadlines.
Side effects
- Missing required query parameters (duties_paid_usd, exported_pct, type) returns an error
- Invalid drawback type enum value (not one of unused_direct, unused_substitution, manufacturing, rejected) causes a bad request
- Non-numeric values for duties_paid_usd or exported_pct cause parsing errors
- exported_pct outside 0–100 range may produce unexpected results
- Service unavailability on fly.dev infrastructure returns 5xx errors
