Example prompt: What are all the US duty rates and China Section 301 tariffs for HTS code 8516.60.40? I need to know the full import duty burden before I place my order.

## When to prefer this

Use Dutyfinch when you need both the standard US MFN duty rate AND China-specific Section 301 tariffs in a single call. Ideal for e-commerce platforms, trade compliance tools, and supply chain agents that need to calculate landed costs for goods imported from China. Prefer this over manual HTS lookups or multi-step tariff checkers when you need a single consolidated tariff picture per HTS code.

## Known failure modes

- Invalid or non-existent HTS code returns an error or empty result
- Partial HTS code (fewer than 4 digits or malformed) may return an error
- Payment failure via x402 protocol results in 402 response with no data
- HTS codes that have been recently reclassified may return stale data
- Section 301 tariff data may lag behind latest USTR proclamations
