customs-hts-classification-mece

customs-hts-classification-mece is a skill for Claude Code, Codex from deciqAI/knowledge-skills. It costs 71 tokens per session (749 once invoked), scanned A, original, MIT.

A method for classifying imported goods under the United States Harmonized Tariff Schedule, the system used to assign customs codes and duties. It breaks ambiguous or multi-purpose products into separate classification questions.

In plain words
What is it for?
Use it for merchandise spanning multiple chapters or having several functions. It follows the customs General Rules of Interpretation and points to official rulings for certainty.
Why use it?
It gives a structured way to resolve cases where several customs headings might appear to fit. The result is one documented, defensible heading rather than an informal guess.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

customs-hts-classification-mece scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Customs — HTS Classification (MECE Decomposition)

Industry front door for mece. Adds domain triggers, example, packs only. Parent Process unchanged. Not legal advice. Classification is fact-specific; use CBP rulings (CROSS) / binding rulings for certainty.

Activate when: classifying merchandise under the HTSUS; ambiguous/multi-function goods; "which heading applies?"; a product spanning multiple chapters. Do NOT activate when: an established binding ruling already governs the exact article.

Why this variant

The parent mece forces mutually-exclusive, collectively-exhaustive buckets. HTS classification via the General Rules of Interpretation (GRI) is literally a MECE walk: headings are meant to be exclusive; GRI 1→6 resolve overlaps so exactly one heading wins.

Domain inputs → parent's Process

  • GRI 1: classify by heading terms + section/chapter notes (start here, exhaustively).
  • If >1 heading fits (not mutually exclusive on its face): GRI 2 (incomplete/mixtures), GRI 3 (most specific → essential character → last in numerical order), GRI 4 (akin), GRI 5 (containers), GRI 6 (subheadings).
  • The goal: a single, defensible heading with the reasoning recorded (reasonable care).

Worked example

A multi-tool with knife, screwdriver, LED light. → Not one obvious heading. Apply GRI 3(b) essential character; if indeterminate, GRI 3(c) last-in-order. Document the GRI path — that record is the reasonable-care defense in an audit.

Compliance anchors

  • HTSUS + GRI; Section/Chapter Notes; 19 U.S.C. reasonable care; CBP CROSS rulings; binding-ruling option.

Packs

  • Solo broker: GRI decision worksheet per SKU.
  • Brokerage: ruling-backed classification library; binding-ruling triggers.

Red flags

  • Jumping to a "close enough" heading without the GRI walk.
  • Ignoring chapter notes that exclude a heading.
  • No documented reasoning for a contestable classification.

Verification

  • GRI 1 applied with section/chapter notes
  • Overlaps resolved via GRI 2–6 in order
  • Single defensible heading selected
  • Reasoning recorded (reasonable care); binding ruling considered

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
