Data Sources & Methodology
Every data point in TradePilot comes from official Taiwanese government sources.
We do not estimate tax rates ourselves. All figures are sourced directly from official databases such as the Customs Administration and the Ministry of Finance, and are kept regularly in sync.

Why Customs Exchange Rates?
- ✓Published by Customs Administration on the 1st, 11th, and 21st of each month
- ✓Legally mandated for dutiable value conversion
- ✓Calculations use customs-published exchange rates; actual duties are subject to customs assessment
- ✗Fluctuates daily, leading to inconsistent calculations
- ✗Not used by customs during clearance
- ✗May cause tax estimate deviations
Customs exchange rates are set under Article 29 of the Customs Act and differ from bank buying and selling rates. TradePilot syncs the latest table after each ten-day update; actual duties remain subject to customs assessment.
Important Regulatory Notes
Low-Value Import Exemption and 6-Times-in-6-Months Rule
Dutiable value of NT$2,000 or less is exempt from customs duty, commodity tax, and VAT; tobacco and alcohol are not eligible.
After the same recipient has more than 6 duty-free clearances in 6 months, the low-value exemption no longer applies from the 7th shipment onward.
⚠️ The platform cannot determine each user's import frequency; confirm against actual clearance records.
FAQ
Where does TradePilot's tariff data come from?
All tariff rates come from the Taiwan Customs Administration Open Data Platform (data.customs.gov.tw), official government data that TradePilot automatically syncs on a regular basis.
Why not use real-time exchange rates?
Customs uses the ten-day customs exchange rate (updated on the 1st, 11th, and 21st of each month), not real-time bank rates. TradePilot uses the same rate as its calculation basis; actual duties remain subject to customs assessment.
How accurate is the AI classification?
Accuracy is divided into three confidence zones: Green (>85%) is high confidence with a full GRI reasoning chain; Yellow (60–85%) provides an initial classification with clear disclosure of risk and alternative candidates; Red (<60%) does not force an answer and recommends expert review. We continuously calibrate accuracy using user feedback.
