## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability us-import-tariff-rate-lookup-6c95f88d
```

Example prompt: What's the full effective US import duty rate for HTS code 8471.30 coming from China — including any Section 301 or IEEPA surcharges — and can you estimate the landed cost on a $25,000 customs value shipment?

## When to prefer this

Use this endpoint when you need a precise, layered breakdown of US import duties for a specific HTS code and origin country, including trade-war surcharges (Section 301, 232, IEEPA) that generic tariff lookups often omit. Especially valuable when calculating landed costs or assessing the real duty burden for US imports in a post-trade-war environment.

## Known failure modes

- Invalid or unrecognized HTS code returns an error
- Unsupported or malformed ISO country code returns a validation error
- HTS code not found in US tariff schedule returns a not-found error
- Missing required parameters (hts or origin) returns a 400 bad request
- Network timeout or upstream data unavailability returns a 5xx error

## How this service works

Estimate the effective US import duty for one HTS code from one origin country. Returns the base rate (MFN or FTA), the additional trade-war layers (Section 301, Section 232, IEEPA) with their Chapter 99 provisions, the combined effective rate, and an optional landed-cost estimate.

## Output

Returns the base tariff rate (MFN or applicable FTA rate), itemized additional trade-war layers including Section 301, Section 232, and IEEPA with their Chapter 99 provision codes, the combined effective duty rate, and optionally a landed-cost estimate in USD if customs_value was provided.
