If you source from China and import into the US, the most dangerous cost mistake you can make is a sentence like this: “the tariff on this product is 25%.” Because in 2026, goods entering the US from China don’t carry a single tariff rate — they carry a stack of tariffs layered on top of each other. Look at only one layer and your landed-cost estimate can be off by a wide margin — and if you get it wrong at the quoting stage, your margin disappears. This article unpacks that stack, layer by layer.
1. The key concept: US tariffs on China add up — they don’t replace one another
This is where most people get caught. US import duties are additive — tariffs from different sources and different legal authorities apply to the same product simultaneously. The full tariff stack on a Chinese import can include the following layers, each stacked on the last:
- Base MFN duty — the standard rate all countries pay, product-dependent, typically 0–15%.
- Section 301 (China only) — 7.5% to 100%, depending on which list your product falls under.
- Section 232 (steel, aluminum, copper) — 50% on steel, 50% on aluminum, 25% on copper and derivatives.
- Section 122 (global surcharge) — a surcharge in effect in 2026, with some goods exempt.
- AD/CVD (if applicable) — anti-dumping and countervailing duties on specific products, often 50%–200%+.
A concrete example of how brutal the stacking gets: import $100,000 of hot-rolled steel (HTS 7208.27) from China. If it falls under both Section 301 List 1 and Section 232 steel, your real duty is base MFN + Section 301 + Section 232 stacked together — nowhere near whatever single rate you had in mind.
2. Some key 2026 rates (verify against your specific product)
These reflect the situation as of 2026, but rates change frequently — always verify against your own HTS code:
- Electric vehicles: 100% — effectively prohibitive; it closes the US market to Chinese EVs.
- Semiconductors, solar cells: 50%
- Steel, aluminum: 25% (at the Section 301 level), higher once Section 232 stacks on
- Non-EV lithium batteries: rose to 25% from January 1, 2026
- Medical gloves: rose to 100%; face masks: rose to 50%
- Natural graphite, permanent magnets: rose to 25%
- Most other goods: 25% (Section 301)
3. Two moving variables you must watch in 2026
Tariffs aren’t static. Two things in 2026 directly affect your cost, with firm dates:
- 178 Section 301 product exclusions expire on November 10, 2026. If you’re currently enjoying a lower rate thanks to an exclusion, you need to know this date and watch whether it’s extended. If it lapses without renewal, your cost jumps. Current exclusions cover solar manufacturing equipment, machinery components, plastic films, electric motors, medical devices, and certain fabrics and vehicle parts.
- A new 12.5% tariff on China is working through the process. In June 2026, USTR proposed an additional 12.5% tariff on China stemming from a forced-labor-related Section 301 investigation (comments closed July 6, hearing July 7). It isn’t finalized, but you should know it’s coming.
4. Three ways to legally lower your tariff bill (many buyers don’t know these)
Beyond calculating what you owe, there are legitimate mechanisms to reduce it:
- Check whether your product has a current exclusion. USTR runs an exclusion process, and the 178 active exclusions may cover your product. Exclusions are granted at the precise 10-digit HTS code level — get it right and you may drop an entire Section 301 layer.
- If you re-export after importing (as-is or after processing), duty drawback can recover up to 99% of duties paid. For buyers doing transshipment or re-export, this is significant.
- If your supply chain involves multiple sales before goods reach the US, the “first sale” rule may let you calculate duty on the lower first-hand price rather than the final transaction value. It’s a technical but legitimate saving.
5. The practical takeaway: don’t estimate cost from a single rate — use the full stack
Here’s an actionable method. When you get a quote on a Chinese product, don’t stop at “oh, that category is 25%.” Instead:
- Classify the product with the correct 10-digit HTS code (get this wrong and everything downstream is wrong).
- Check each layer: base MFN + Section 301 (which list?) + Section 232 (if steel/aluminum/copper) + Section 122 + AD/CVD (if applicable).
- Check whether any current exclusion applies.
- Add all the layers together — that’s your real landed tariff cost.
Free online tariff calculators (enter an HTS code and they stack the layers automatically) can do this for you. The core mindset: the complexity of US tariffs on China isn’t that the rates are high — it’s that they’re additive and frequently changing. Treat it as a stack to be checked layer by layer, not a single number, and you won’t get burned when you quote.
The bottom line
The real tariff cost of importing from China is rarely a single percentage — it’s the result of MFN, Section 301, 232, 122, and AD/CVD stacked together, on top of live variables like the November exclusion expiry and the new 12.5% tariff in the pipeline. Treat it as a dynamic stack to check layer by layer, and make use of legitimate tools like exclusions, drawback, and first sale — that’s how you cost accurately and avoid hidden losses at the quoting stage.
Tariff rates and dates reflect the situation as of mid-2026 and change frequently through USTR and CBP actions. Always verify against your specific 10-digit HTS code and the latest official notices before relying on any figure. This article is general information, not legal, customs, or trade advice.
