## 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 sitecheck-uk-trade-tariff-lookup-24a04523
```

Example prompt: What's the UK import duty rate and VAT for portable laptops — commodity code 8471300000 — if they're coming from the US?

## When to prefer this

Use this endpoint when you need UK-specific import or export duty rates, VAT treatment, or tariff preference information sourced directly from the UK Trade Tariff service. Prefer this over generic customs databases when you need post-Brexit UK tariff schedules, preferential rates under UK trade agreements, or legal basis references. It is ideal for e-commerce, compliance, supply chain, and logistics agents needing accurate UK customs data.

## Known failure modes

- Invalid or unrecognised commodity code returns empty or error response
- Keyword search with no matching headings returns empty measures list
- Origin country code not recognised may omit preferential duty results
- Truncated or malformed code (not 6–10 digits) may fail validation
- API unavailability from underlying UK Trade Tariff service causes timeout or error

## How this service works

Returns UK Global Tariff data for a 6–10-digit commodity code via the UK Trade Tariff API (OGL v3): description, third-country duty rate, VAT, measures, and preferential rates for a given origin country. Text search (`q`) returns matching commodity headings. Coverage: UK only, post-Brexit schedule.

## Output

Returns a JSON object with the commodity code, description, third-country duty rate, VAT rate, tariff preference measures (including duty expressions, legal bases, effective dates, origin codes, import/export flags), a link to the official UK Trade Tariff page, validity dates, and a disclaimer noting the data is informational only.
