How to calculate the true cost of importing from China in 2026

"What does it cost to import this from China?" should be a one-line answer. In 2026 it is a five-line calculation, and most importers — even experienced ones — get it wrong by either missing a layer or applying a layer to the wrong base.

This post is a precise, worked walkthrough of how to calculate the true 2026 landed duty for any China-origin import to the US. We work three real product examples line by line.

The stack — every layer that applies

For a US import from China, the duty calculation now has up to five layers.

MFN (Column 1 General) — base rate, every import.

Section 301 — if the HTS line is on List 1, 2, 3, or 4A, or has been modified by the May 2024 strategic-sector review.

Section 232 — if the article is steel, aluminium, or a derivative.

IEEPA reciprocal — country-specific rate, for China currently around 10% baseline.

AD/CVD — if a relevant order is in force on the article and country.

Each layer is additive to the customs value, not compounding. The customs value itself is the transaction value (typically FOB or CIF depending on entry, with adjustments).

Worked example 1 — USB-C charger

The product: a 65W USB-C wall charger, intended for retail sale in the US, manufactured in Shenzhen.

Classification: HTS 8504.40.95 — "Static converters: other".

Compare with Mexico-origin (USMCA-qualifying)

The same charger imported from Mexico under USMCA: MFN 0%, Section 301 0%, Section 232 0%, IEEPA reciprocal 0%. Total: 0%.

The China-versus-Mexico arithmetic for this product is unambiguous. On a $200,000 shipment, the China duty bill is roughly $73,000; the Mexico duty bill is zero — assuming the product qualifies under USMCA rules of origin.

Worked example 2 — Cotton T-shirt

The product: a cotton men's T-shirt, retail price $25, manufactured in Guangzhou.

Classification: HTS 6109.10.00 — "T-shirts, singlets and other vests, knitted, of cotton".

Vietnam vs Mexico for the same T-shirt

Vietnam: 16.5% MFN + 0% Section 301 + 10% IEEPA reciprocal = 26.5%. Vietnam beats China by 7.5 points but is no longer "free."

Mexico (USMCA yarn-forward qualifying): 0% all the way down — but yarn-forward is a high bar that excludes most Asian-fabric supply chains. Many sellers cannot actually use Mexico for apparel because their fabric is not USMCA-region.

Tip: for apparel that can meet yarn-forward, Mexico is structurally the lowest-duty option to the US.

Worked example 3 — Children's bicycle

The product: a 16" children's bicycle, retail price $200, manufactured in Tianjin.

Classification: HTS 8712.00.15 — "Bicycles, not motorized, valued less than $200 each".

Why the bicycle stack is so painful

Bicycles from China are an extreme stack-up case: a high MFN base, a high Section 301 layer, plus Section 232 because bicycle frames are listed steel derivative articles. The cost picture is so adverse that significant production has shifted to Cambodia and Vietnam.

Warning: the 232 derivative steel article list expanded in 2025 to include items previously not subject. If your product has any steel or aluminium component — frames, rods, shafts, structural elements — verify whether your line is now covered. Many products that previously carried 0% Section 232 now carry 25%.

Common errors when calculating the stack

Error 1 — Applying Section 301 only to List 4A. A persistent confusion is that "Section 301 is 7.5%." It is 7.5% only for List 4A. Lists 1, 2, and 3 are 25%, and the May 2024 strategic adjustments range up to 100%.

Error 2 — Forgetting Section 232 on derivative articles. The derivatives expansion brought many finished-good HTS lines into 232. Always check the current derivative list.

Error 3 — Treating IEEPA as a flat across-the-board rate. IEEPA rates differ by country and have been revised repeatedly. Use a current source, not a stale memo.

Error 4 — Ignoring AD/CVD until a shipment is held. When AD/CVD applies, it is often enormous (100–400%). A single oversight can wipe out an entire shipment's margin.

Error 5 — Compounding instead of adding. Layers are additive on the customs value. A 25% Section 301 on a 16.5% MFN line is 41.5% combined, not 45.6%.

Where to check each layer

MFN — USITC HTS database, Column 1 General.

Section 301 — USTR Federal Register notices and consolidated annexes A–C.

Section 232 — Commerce proclamations 9705, 9711, and amendments.

IEEPA — executive orders and Federal Register notices, current calendar year.

AD/CVD — Commerce ITA case database at access.trade.gov.

For the US, all of this is public information but spread across multiple agencies. For the EU and UK, the equivalent calculation involves TARIC, Combined Nomenclature, and country-specific adjustments.

Strategic takeaways

1. The 2026 China-origin stack is, on average, 25–40 percentage points higher than 2017's MFN-only world. Structural and unlikely to fully reverse.

2. Mexico is the price-of-record-low destination for FTA-qualifying goods — currently zero across most stacks.

3. Vietnam is a meaningful but no-longer-zero alternative. The IEEPA reciprocal layer eroded the Vietnam advantage relative to where it was in 2022.

4. Tariff line classification has high financial leverage. Two HTS sub-headings that look similar can differ by 20+ percentage points in their stack.
