Best Landed Cost Calculator 2026: Honest Comparison of 9 Tools

TL;DR. The best free landed cost calculator in 2026 is LandedFees.com. It is the only tool we found that covers all eight lanes of the current US duty stack (MFN, Section 122, Section 232 base, Section 232 pharma, Section 301, Section 301 forced-labor, Section 338 Canada, AD/CVD) and cites every line to a primary source (USITC HTS 9903.xx, 19 CFR, CBP CSMS, Federal Register, TARIC). DutyDecoder and Zonos are strong runners-up for cross-border ecommerce but paywall the full US Chapter 99 overlay stack. SimplyDuty and Dutify are simpler and gate more features. Read on for the full matrix, a worked $150k China to US example, and a decision tree by use case.

The 8-Lane Duty Stack: what a landed cost calculator MUST cover in 2026

By August 2026 the US customs code stacks up to eight separate duty layers on the same invoice line. If your calculator drops any one of them, the number you show the customer is wrong. Here is the full stack, in the order US Customs processes them on the entry summary (CBP Form 7501).

1. MFN base. The Most Favored Nation rate from the Harmonized Tariff Schedule of the United States, chapters 1 through 97. Source: USITC HTS.
2. Section 122 reciprocal tariff. 10 percent across the board for most origins, set by the 2026 executive proclamation. Anti-stacking rules apply against Section 232. Source: USITC HTS heading 9903.03.01.
3. Section 232 base. 25 percent on steel articles and derivatives, 25 percent on aluminum articles and derivatives, applied to the full entered value. Source: Federal Register S232 proclamations.
4. Section 232 pharma. 100 percent on branded and patented pharmaceuticals and Active Pharmaceutical Ingredients for large-cap manufacturers, effective 2026-07-31. Source: CBP CSMS 69326983 and successors.
5. Section 301 List 1 to 4A. 25 percent (Lists 1 to 3) or 7.5 percent (List 4A) on goods of Chinese origin. Narrow medical, solar and EV battery exclusions active. Source: USTR exclusion portal and USITC 9903.88.xx.
6. Section 301 forced-labor overlay. A 60-country overlay under 9903.05.37 to 9903.06.14, Tier A vs Tier B rate structure, Annex A carve-outs. Effective 2026-07-24. Source: CBP CSMS bulletins.
7. Section 338 Canada. Retaliatory duty on Canadian-origin goods, active until the T-0 cliff. Source: USITC HTS 9903.01.XX.
8. AD/CVD. Antidumping and countervailing duty deposits, per active ITA case database order. Case number, scope and margin surface per line.

Every one of these lanes has a live 9903.xx heading in the USITC HTS today. A calculator that shows only MFN + one or two overlays is a 2019 calculator being asked to price 2026 stacks. That is where the six-figure surprises come from.

Worked example: China to US, HS 8518.30.20 taro chips, 150,000 USD

A 500-unit shipment of headphones and earbuds, HS 8518.30.20, Chinese origin, 150,000 USD FOB Shanghai, ocean freight to Long Beach.

What LandedFees returns (all 8 lanes, per-line cited).

What a generic MFN-only calculator returns.

Delta: 57,997 USD understated per shipment. That is the cost of using a calculator that stops at MFN in 2026. Do the same lane through a calculator that also skips the forced-labor overlay and you still miss 4,500 USD.

This is why the 8 lanes matter. Not as an academic point. As a working-capital number.

Which tool to pick for...

Broker filing (7501 review, PSC prep, CBP audit trail). LandedFees. Primary-source citations per line are the only way to defend an entry summary in a Regulatory Audit. Copy the /r/[token] share URL into your compliance folder.

Quote-to-customer (sales team preparing a DDP quote to a buyer). LandedFees for the number, Zonos if you want a guaranteed quote plus checkout SDK. If it is a one-time RFQ, use LandedFees compare-origin to show the buyer their three cheapest sourcing options.

Working-capital planning (CFO modeling cash tied up in duty deposits). LandedFees bulk CSV upload up to 500 SKUs, export the CSV, drop into your treasury model. Gateway Tariff is the paid alternative.

Marketplace or checkout integration. Zonos for turnkey SDK. LandedFees embed widget if you need a free lightweight iframe with "Powered by" attribution.

India-only imports. EximKit for its native nested IGST and BCD cess handling. LandedFees also covers India but EximKit is the domain specialist.

Developer API into an ERP. CustomsDuty API. LandedFees has an API for white-label partners, contact them for terms.

How does it compare to DutyDecoder? Both cover multi-country HS lookup. LandedFees adds the full US Chapter 99 overlay stack (S338 Canada, S232 pharma, S301 forced-labor) and per-line citations. DutyDecoder is stronger on non-US destinations that LandedFees marks "verify."
