Query HS code detail information for analysis reports — retrieve Chinese and English descriptions for a given HS (Harmonized System) code from customs data. Provides comprehensive product classification details to help trade professionals, analysts and import-export practitioners understand what products a specific HS code represents. Essential for tariff code lookup, product classification verification, customs code interpretation and trade data analysis preparation across global customs trade data.

Query HS code detail information — retrieve Chinese and English descriptions for a given HS code. Trigger: HS code detail, tariff code description, customs code lookup, HS code meaning, product classification

Customs Analysis HS Code Detail

Query HS code detail information from customs data using the UpKuaJing Open Platform API.

Overview

This skill retrieves detailed description information for a given HS (Harmonized System) code, including both Chinese and English descriptions. This helps you understand what products a specific HS code represents.

Running Scripts

Environment Setup

1. Check Python: python --version
2. Install dependencies: pip install -r requirements.txt

Script directory: scripts/*.py Run example: python scripts/*.py

Important: Always use direct script invocation like python scripts/customs_analysis_hscode_detail.py. Do NOT use shell compound commands like cd scripts && python customs_analysis_hscode_detail.py

HS Code Detail Query (customs_analysis_hscode_detail.py)

• Return granularity: One record per query
• Use cases: Look up product classification for an HS code, get Chinese/English descriptions of tariff codes
• Examples:
  • "What does HS code 04021000 mean?"
  • "Get the description for HS code 04021000"
• Parameters: See HS Code Detail API

API Key and Top-up

This skill requires an API key. The API key is stored in the ~/.upkuajing/.env file:

bash

cat ~/.upkuajing/.env

Example file content:

text

UPKUAJING_API_KEY=your_api_key_here

API Key Not Set

First check if the ~/.upkuajing/.env file has UPKUAJING_API_KEY; If UPKUAJING_API_KEY is not set, prompt the user to choose:

1. User has one: User provides it (manually add to ~/.upkuajing/.env file)
2. User doesn't have one: You can apply using the interface (auth.py --new_key), the new key will be automatically saved to ~/.upkuajing/.env Wait for user selection;

Account Top-up

When API response indicates insufficient balance, explain and guide user to top up:

1. Create top-up order (auth.py --new_rec_order)
2. Based on order response, send payment page URL to user, guide user to open URL and pay, user confirms after successful payment;

Get Account Information

Use this script to get account information for UPKUAJING_API_KEY: auth.py --account_info

API Key and UpKuaJing Account

• Newly applied API key: Register and login at UpKuaJing Open Platform, then bind account

Report Skill Call Errors

When an API call fails or returns abnormal data (server error, timeout, malformed response, etc.), explain the anomaly to the user in natural language and ask whether to report it to the platform for troubleshooting. Only run the report after user confirmation:

bash

python scripts/error_report.py --params '{"requestPath":"/agent/customs/analysis/hscode/detail","requestId":"f47ac10b58cc4372a5670e02b2c3d479","context":"HS code detail query failed with a server error"}'

• Do not report normal business conditions (insufficient balance, invalid API key, parameter errors) — handle them via their own flows
• Error reporting does not incur query fees
• Parameters: See Error Report API

Fees

All API calls incur fees, different interfaces have different billing methods.

Latest pricing: Users can visit Detailed Price Description Or use: python scripts/auth.py --price_info (returns complete pricing for all interfaces)

Query Billing Rules

Billed by number of calls, each call returns one HS code detail:

• Each API call incurs a fee
• Before execution:
  1. Inform user that this query will incur a fee
  2. Stop, wait for explicit user confirmation in a separate message, then execute script

Fee Confirmation Principle

Any operation that incurs fees must first inform and wait for explicit user confirmation. Do not execute in the same message as the notification.

Workflow

Decision Guide

User Intent	Use API
"What does HS code 04021000 mean?"	HS Code Detail Query
"Get description of tariff code 04021000"	HS Code Detail Query
"Explain product classification for 04021000"	HS Code Detail Query

Usage Examples

Query HS Code Detail

User request: "What does HS code 04021000 mean?"

bash

python scripts/customs_analysis_hscode_detail.py --params '{"hscode":"04021000"}'

Error Handling

• API key invalid/non-existent: Check UPKUAJING_API_KEY in ~/.upkuajing/.env file
• Insufficient balance: Guide user to top up
• Invalid parameters: Must first check the corresponding API documentation in references/ directory, get correct parameter names and formats from documentation, do not guess
• Skill call errors / abnormal responses: Explain to the user and, with user confirmation, report to the platform via python scripts/error_report.py (see Report Skill Call Errors)

API Documentation Reference

• HS Code Detail: Check references/customs-analysis-hscode-detail-api.md
• Error Report: Check references/skill-error-report-api.md

Best Practices

1. Check API documentation:

   • Before executing queries, must first check the corresponding API reference documentation
   • Check references/customs-analysis-hscode-detail-api.md
   • Do not guess parameter names, get accurate parameter names and formats from documentation

2. HS code format:

   • Use complete 8-digit HS code format (e.g., "04021000")

3. Cross-skill usage:

   • First use customs-analysis-hscode-search to find matching HS codes, then use this skill to get descriptions
   • Combine with customs-analysis-trends, customs-analysis-area, or customs-analysis-trade-percent for detailed analysis after understanding the HS code meaning

Notes

• hscode is the only required parameter
• descZh is the Chinese description of the HS code
• descEn is the English description of the HS code
• File paths use forward slashes on all platforms
• Prohibit outputting technical parameter format: Do not display code-style parameters in responses, convert to natural language
• Do not estimate or guess per-call fees — use python scripts/auth.py --price_info to get accurate pricing information
• Do not guess parameter names, get accurate parameter names and formats from documentation
