Import Duty & Tariff Calculator (2026)
Estimate US import duty, Section 301 China tariffs, Section 232 steel/aluminum tariffs, 2025 reciprocal/IEEPA tariffs, MPF, HMF, and broker fees for any shipment. All rates updated for 2026.
Shipment
Use the value declared on the commercial invoice (entered value). CBP duty is calculated on this number.
Subject to Section 301 (List 1-4A typically 25%) plus 2025 IEEPA fentanyl reciprocal actions (20% additional on most goods). Some categories phased to 50-100% (EVs, batteries, semiconductors).
Harbor Maintenance Fee (0.125%) only applies to ocean cargo entering through US ports.
Typical 2026 broker entry fees run $100-$275 per entry; $175 average for a single-port single-HTS entry.
Tariff Treatment
Knit and woven apparel average 11.5-16.5%. Cotton tees ~16.5%, polyester ~32% (rare), wool ~16%.
Disclaimer: This calculator produces a working estimate using public HTS, USTR, Commerce Section 232, CBP user fee, and broker market data current to early 2026. It is not legal or customs advice. Tariff rates change frequently - verify with your customs broker, USTR.gov, and CBP's HTS lookup at hts.usitc.gov before relying on this for an actual entry. Antidumping (AD), countervailing (CVD), Section 201 safeguards, agricultural TRQs, and product-specific exclusions are not modeled here and can change your real-world rate materially.
Why Tariff Stacking Matters in 2026
In 2018, a typical import duty calculation was the base HTS rate plus MPF and HMF — three line items. In 2026, the same shipment can carry up to six stacked layers: base HTS, Section 301, Section 232, 2025 IEEPA reciprocal, AD/CVD case orders, and any Section 201 safeguard.
A $50,000 shipment of Chinese-origin consumer electronics that used to cost about $200 in total fees can now exceed $22,500 after Section 301 (25%) and the 2025 IEEPA China add-on (20%) stack on top of MPF and HMF. The same shipment from Vietnam might cost $10,250 (20% IEEPA reciprocal). From Mexico, if USMCA-qualifying, it might cost under $700.
That gap is why most importers in 2026 are restructuring sourcing, evaluating FTZ and bonded warehouse setups for duty deferral, and rethinking whether US warehousing inside a low-duty regime beats offshore stock-and-ship. This calculator helps you size the stack quickly before you commit to a sourcing decision.
The 2026 US Import Tariff Stack
Every US import in 2026 can carry these duty and fee layers. Not all apply to every shipment — country of origin, HTS code, and entry method determine which layers stack.
| Tariff layer | Legal authority | Typical 2026 rate | Notes |
|---|---|---|---|
| Base HTS duty | USITC Harmonized Tariff Schedule | 0-37.5% | Looked up by 10-digit HTS code at hts.usitc.gov |
| Section 301 | USTR (Trade Act of 1974) | 25% / 50% / 100% | China origin only. Lists 1-4A. EVs/batteries/semis at higher tiers in 2025-2026. |
| Section 232 | Commerce (Trade Expansion Act 1962) | 25% steel / 10% aluminum | Most countries. Some exemptions narrowed in 2025. |
| 2025 IEEPA reciprocal | White House (IEEPA / Trade Expansion Act) | 10-25% by country | Applied April 2025; deals signed through Q3 2025 settled most rates. |
| AD / CVD | Commerce + ITC | 30-300% | Case-specific. Common targets: steel, solar, chemicals, lumber. |
| Section 201 | USITC safeguard | 14-30% | Currently active on solar cells, washing machines. |
| MPF | CBP user fee | 0.3464% | Min $33.58 / max $651.50 per entry (FY2026) |
| HMF | CBP user fee | 0.125% | Ocean cargo only |
| Broker entry fee | Private (your broker) | $100-$275 | Per single-entry filing; lower with PMS / continuous bond |

Three 2026 Tariff Reduction Strategies That Still Work
- FTZ-activated warehousing. If you import continuously and re-export any portion of your inventory, an FTZ inside or adjacent to your port saves duty on every re-exported unit and defers duty on US-bound units until withdrawal. Even with no re-export, FTZ inverted-tariff election lets you pay duty on the finished product's HTS rate instead of the components, which often saves 5-15% when finished goods have a lower MFN rate than parts. See our Free Trade Zone Costs guide.
- Bonded warehouse for project-based importers. A bonded warehouse defers duty up to 5 years and allows duty-free re-export. Lower setup cost than an FTZ; right answer for one-time large containers, seasonal cycles, or trial sourcing decisions. See our Bonded Warehouse Costs guide.
- USMCA-qualified sourcing. Mexico- and Canada-origin goods that qualify under USMCA rules of origin enter duty-free even in the 2025 IEEPA regime. Many electronics, auto parts, and finished consumer goods now carry a 20-40% effective tariff advantage when sourced from USMCA partners over China or Vietnam. If you can restructure a bill of materials or final assembly to qualify, the math is usually compelling. Combine with port-of-entry warehousing along the southern border to keep inventory close to demand without paying duty stack on every SKU.
All three strategies pair well with a US 3PL footprint. Importers who used to land containers and ship direct from a foreign DC are increasingly running US warehousing as a duty-management layer, not just a distribution layer.
