HTS Classifier — US Tariff Code & Duty Rate Lookup

Classify products into HTS codes and get current 2026 US duty rates including Section 301, Section 232, and IEEPA (Section 122) tariffs.

When to Use

USE this skill when:

"What's the HTS code for solar panels?"
"Tariff rate on steel pipes from China"
"Look up duty for HTS 8541.40"
"How much import tax on lithium batteries?"
"Classify this product for customs"
Any question about US import duties or tariff codes

When NOT to Use

DON'T use this skill when:

Filing customs entries or ISF → use a customs broker
Legal classification disputes → consult a licensed customs broker
Export controls / ITAR / EAR → use export compliance tools
Tariff engineering or structuring advice → consult trade counsel

Commands

Search by product description

python3 ~/.openclaw/skills/hts-classifier/scripts/classify.py --query "solar panels"

Look up a specific HTS code

python3 ~/.openclaw/skills/hts-classifier/scripts/classify.py --hts "8541.40"

Both at once

python3 ~/.openclaw/skills/hts-classifier/scripts/classify.py --query "photovoltaic cells" --hts "8541.40"

With LLM ranking (optional, slower — uses local Ollama)

python3 ~/.openclaw/skills/hts-classifier/scripts/classify.py --query "solar panels" --rank

Output

Returns JSON with top matching HTS codes including:

hts_code — The harmonized tariff code
description — Official HTS description
base_duty — General (MFN) duty rate
section_301_china — Section 301 additional duty (%) for Chinese-origin goods
section_232 — Section 232 duty (%) for steel/aluminum
section_122 — IEEPA/Section 122 universal tariff (%)
total_estimated — Total estimated effective duty rate
warnings — Active tariff overlays and special notes
trade_data — Import volume data when available

Environment Variables (all optional)

Variable	Default	Purpose
`OLLAMA_URL`	`http://localhost:11434`	Local Ollama endpoint for LLM ranking
`OLLAMA_MODEL`	`qwen3:8b`	Ollama model for ranking (must support JSON output)
`OLLAMA_TIMEOUT`	`30`	Seconds before ranking times out (falls back to FTS5)
`HTS_LOG`	`/tmp/hts-classifier.log`	Log file path (queries are logged — use `/dev/null` to disable)
`HTS_API_KEY`	(unset)	Cloudflare D1 API token for direct DB fallback — only set if you operate the ustariffrates D1 database

Network Interactions

Always: queries ustariffrates.com/api/search (public API, no auth)
Optional: calls local Ollama (localhost:11434) when --rank is used
Optional: queries Cloudflare D1 only if HTS_API_KEY is explicitly set (disabled by default)

Notes

Data is live from ustariffrates.com (2026 HTS schedule)
Includes Section 301, 232, and IEEPA (Section 122) tariff overlays
Results are informational — always verify with a licensed customs broker for formal entries
No API key required for public search
Queries are logged to HTS_LOG — set to /dev/null if handling sensitive product descriptions
