Tariffs API vs Easyship.
Easyship is a shipping platform with duty calculation included. We're just the duty calculation, surfaced as a REST endpoint you can drop into anything.
Easyship serves 100,000+ businesses with a broader shipping platform: rate comparison, label generation, tracking, returns, plus tax and duty calculation as a feature. If you want shipping and duty under one roof, they're a strong self-serve option. If you already have shipping figured out and just need the duty data, you're paying for a lot you won't use.

When Easyship is the right pick
- →You're building or running a shipping operation and want one platform for rates, labels, tracking, and duty estimation.
- →You ship from one place to many destinations and want a managed UI with duty estimates built in.
- →You prefer a free plan to start and want to add features as you grow.
When Tariffs API is the right pick
- ✓You already have a shipping stack and just need a duty calculation API.
- ✓You want US-specific tariff stacking — Section 301, 232, IEEPA, Chapter 99 — surfaced explicitly in the response.
- ✓You're integrating duty calc into a custom checkout, ERP, marketplace, or quoting tool — not running shipping operations.
- ✓You want bulk /resolve and MCP server access for catalog-scale or AI-agent workflows.
One endpoint. Deterministic JSON.
GET /api/v1/tariffs/resolve?hts=8541.10.00.80&origin=CN returns base duty plus every applicable Chapter 99 measure — Section 301, 232, IEEPA, and reciprocal duties stacked correctly. JSON in, money out. Built for the duty calculation problem specifically, not bundled with a shipping platform.

Can I use Tariffs API alongside Easyship?
Yes. If Easyship handles your shipping rates, labels, and tracking, you can still hit Tariffs API directly for duty calculation in your own checkout, cart, or quote flow. They're complementary — we just give you the duty number with finer-grained US tariff detail.
Does Easyship's duty calculation cover Section 301 / IEEPA stacking?
Easyship surfaces tax and duty calculation but doesn't emphasize US-specific trade-measure stacking detail (Section 301, 232, IEEPA, Chapter 99) in their public marketing. If your use case depends on getting US trade-remedy stacking right, our /resolve response returns each applicable measure explicitly.
Is Tariffs API cheaper than Easyship?
Different products, different value. Easyship's subscription buys a full shipping platform. Our $199 buys a focused duty API with 100,000 calls included. Compare on what you actually need.
