hts classification audit
Example session with this skill installed
I'm importing a "smart mug" with a built-in battery and heating element from China. My supplier says it's 8516.79. Can you audit this for US entry?
- Read your context and instructions
- Compiled the hts classification audit
HTS: 8516.79.0000 (Verify)
GRI: 1 (Heading 8516 covers electro-thermic appliances)
Overlays: Section 301 (China) Ch 99, Subch III
Note: GRI 3(b) analysis required if sold with charging base.
Action: Verify heating element wattage and battery capacity.

About this skill
The problem
Importers face severe legal and financial risk when relying on supplier-provided HS codes or outdated duty rates. Misclassification leads to overpaid duties, missed Chapter 99 overlays, or CBP penalties for failing the "reasonable care" burden.
What it does
- Derives defensible 10-digit HTSUS classifications using strict GRI methodology.
- Maps contention between competing headings to show exactly which product facts determine the final code.
- Identifies all applicable Chapter 99 overlays, trade remedies (Section 301/232), and AD/CVD duty stacks.
- Audits existing product catalogs to surface refund opportunities and underpayment liabilities.
- Generates broker-ready documentation including documented rationale and CROSS ruling citations.
Why this beats prompting it yourself
General LLMs frequently hallucinate duty rates or cite the first 6 digits of a foreign HS code as a complete US classification. This skill enforces a non-negotiable verification workflow that requires live HTSUS lookups and documented GRI reasoning for every SKU.
Use cases
- Classifying new product lines for US customs entry.
- Auditing a catalog for duty recovery after tariff program changes.
- Validating supplier-provided codes before they hit a commercial invoice.
- Preparing comprehensive briefing packages for a licensed customs broker.
Known limitations
Does not provide final legal sign-off or valuation advice. Without live web access, it provides GRI analysis and contention mapping but cannot output filable rates or codes.
