# CBAM Scope Checker — CN/HS Code Lookup

> CBAM Scope Checker — CN/HS Code Lookup is a paid API for AI agents from reg.chainverdict.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Checks whether a given CN/HS code falls within the EU Carbon Border Adjustment Mechanism (CBAM) scope, returning the sector, de minimis applicability, and declaration deadlines.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 cbam-scope-checker-cn-hs-code-lookup-76b31c31
```

Example prompt: Can you check if CN code 7208 is within CBAM scope — I need to know the sector, whether the 50-tonne de minimis applies, and what the declaration deadlines are?

## When to prefer this

Choose this endpoint when you need a fast, automated, per-code CBAM scope determination during import planning, compliance screening, or document preparation workflows. It is purpose-built for CBAM Annex I classification with de minimis and deadline context baked in, unlike generic HS code lookup tools that lack CBAM-specific regulatory metadata. Ideal for agentic workflows that need to route goods through CBAM declaration pipelines.

## Known failure modes

- Missing or malformed CN code parameter — returns validation error
- CN code not found in bundled Annex I list — returns weak non-match (not proof of exclusion)
- Outdated Annex I code list if regulation amendments have occurred since last bundle update
- Ambiguous or partial CN code (too few digits) — may return imprecise prefix match

## How this service works

Is this CN code inside the CBAM Carbon Border Adjustment Mechanism? Returns the sector, whether the 50-tonne de minimis applies, and the declaration deadlines. Longest-prefix match against the bundled Annex I code list — a match is strong, a non-match is weak and never proof of exclusion.

## Output

Returns the CBAM sector name (e.g. steel, cement, aluminum, fertilizers, electricity, hydrogen), a boolean or flag indicating whether the 50-tonne de minimis exemption applies, the relevant declaration deadlines, and a match confidence indicator (strong for a positive prefix match against Annex I, weak/non-conclusive for a non-match — noting that a non-match is never proof of exclusion).
