Eight years ago, Section 232 of the Trade Expansion Act of 1962 was a fairly narrow tool: a 25% duty on steel and a 10% duty on aluminum, aimed at a specific set of raw and semi-finished mill products. Anyone shipping finished goods — kitchenware, furniture, machinery, electronics housings — could largely ignore it. That is no longer true. Through a series of proclamations stretching from mid-2025 into mid-2026, the U.S. administration has doubled the base rates, rebuilt the way duties are calculated, and pulled hundreds of downstream product categories into scope. For freight forwarders and the importers they serve, Section 232 has quietly become one of the most disruptive line items on a landed-cost sheet.

This article walks through where the program stands as of late summer 2026: how the rate structure is now tiered, which countries get relief and on what terms, why the list of “derivative products” keeps expanding, and what forwarders and shippers can actually do about it. Along the way we will point out where a logistics partner’s operational choices — HTS classification support, routing, hale ukana, documentation — can meaningfully change the duty a shipment ends up paying.

None of this is abstract policy trivia for people moving freight out of China. Steel racks, aluminum housings, fabricated metal components, and dozens of other categories common in cross-border e-commerce shipments now sit somewhere inside this tiered structure, and the tier a given SKU falls into can swing landed cost by tens of percentage points. Understanding the mechanics well enough to plan around them, rather than reacting after a shipment is already at the port, is what separates a smooth quarter from an expensive one.

A Fast-Moving Target: The 2025–2026 Timeline

Section 232 has changed shape roughly every few months since mid-2025, and the pace has not slowed. Keeping a simple timeline on hand is more useful than memorizing any single rate, because the rate that mattered in January is often not the rate that applies today.

lā	He aha i hana ai
May 2018	Original Section 232 tariffs take effect: 25% on steel, 10% on aluminum for most trading partners.
May 2025	Steel and aluminum duties are doubled to 50% for nearly all countries; the UK is held at 25% under the bilateral Economic Prosperity Deal.
Aug 2025	Following the first-ever product inclusions process, the Commerce Department adds more than 400 additional HTSUS subheadings to the derivative product list, sweeping in a wide range of downstream finished goods.
Apr 2026	A new proclamation restructures the whole program: duties now apply to the full customs value of covered goods rather than only the metal content, derivative products are split into a 50% “wholly metal” tier and a 25% “derivative” tier, and the inclusions process is eliminated.
May 2026	A further proclamation widens the reduced-rate list to more industrial and agricultural equipment, lowers the U.S.-content exemption threshold from 95% to 85%, and adds new items — including steel racks and aluminum lithographic plates — to the derivative list.

The pattern worth noticing is not any individual change but the direction of travel: broader product coverage, duty calculated on full value rather than metal content, and a growing patchwork of country-specific and product-specific carve-outs layered on top of a high base rate. Each of those threads adds a compliance step that a shipment either gets right at the time of entry or pays for later.

The June 2026 Recalibration: Rates, Thresholds, and Relief

The April 2026 proclamation did the heavy structural lifting — full customs value as the duty base, a two-tier rate system, no more piecemeal inclusions process. The June 2026 proclamation that followed two months later was less about rewriting the framework and more about calibrating it: widening the reduced-rate list, loosening the U.S.-content exemption, and adding a handful of newly captured products. The two changes are best read together.

pae	uku	Pili ia
Annex I-A	50% ad valorem	Articles that are wholly or almost wholly steel or aluminum, plus most copper articles and a set of heavily metal-intensive derivatives.
Annex I-B	25% ad valorem	Most derivative products — finished or semi-finished goods where steel, aluminum, or copper is a major but not exclusive input.
Reduced-rate list	15% ad valorem	Agricultural equipment, residential HVAC systems and components, select industrial machinery, and certain electrical grid equipment, through December 31, 2027.
Excluded / de minimis	0% (Section 232)	Articles where the covered metal is under 15% of total weight, and goods removed from the derivative list under Annex II — though many still face the separate Section 122 global tariff.

The U.S. Content Threshold Moved from 95% to 85%

One of the more consequential technical changes in the June proclamation is easy to miss in a headline summary. Previously, a derivative product qualified for the near-total exemption only if at least 95% of its steel or aluminum content was melted and poured, or smelted and cast, in the United States — an extremely high bar for most global supply chains. The June revision lowered that threshold to 85%. It is still a demanding standard for anything sourced outside North America, but it does open the exemption to a meaningfully larger set of hybrid-sourced components, particularly for manufacturers who blend U.S. mill product with a smaller share of imported metal.

The Reduced 15% List Kept Growing

Agricultural equipment and residential HVAC systems were early additions to the 15% reduced-rate category; the June update folded in more industrial machinery and reaffirmed the rate through the end of 2027. For importers of capital equipment, this tier is worth checking line by line — the gap between 15% and 25% or 50% is often the difference between a viable landed cost and a canceled order.

Derivative Products: Why the Net Keeps Widening

The single biggest operational headache in this program is not the rate — it is scope. “Derivative product” sounds like a narrow technical term, but in practice it now covers a huge share of manufactured goods that contain meaningful steel or aluminum content: fabricated metal parts, appliances, furniture components, racking systems, lithographic plates, HVAC equipment, and dozens of other categories added across the August 2025, April 2026, and June 2026 actions.

Customs and Border Protection generally applies a two-part test to decide whether a finished good counts as a derivative: whether steel, aluminum, or copper accounts for a significant share of the article’s material cost, and whether the article would not itself be classified as a raw mill product. That test is applied at the HTS subheading level, and the line between a covered and a non-covered classification can sit between two adjacent eight- or ten-digit codes for products that look, to a non-specialist, functionally identical. A supplier changing a component’s material mix by a few percentage points, or a broker filing under a slightly different subheading, can shift a shipment from duty-free to a 25% or 50% liability without anyone intending it.

This is also why the list moves in both directions. The April 2026 proclamation removed a large number of low-metal-content items from scope even as it added others, and the June update did the same on a smaller scale. A product that was covered in March may not be covered in July, and vice versa. Anyone still working from a product-tariff mapping built even six months ago should assume it needs to be rechecked.

Country Treatment: Who Gets the 15% Cap and Who Doesn’t

Section 232 duties apply globally by default, but a growing set of bilateral arrangements caps the effective outcome for specific trading partners. The table below summarizes where things stood as of the June 2026 proclamation.

Kinohi	lapaʻau	Notes
EU, UK, Japan, Korea, Switzerland, Taiwan, and several Latin American partners	Effective cap around 15% total duty outcome	Exact outcome depends on the product’s pre-existing MFN or reciprocal rate; the cap does not always mean a flat 15%.
Canada and Mexico (USMCA)	Duty applies only to non-U.S. content	A minimum effective rate of 15% still applies once non-U.S. content is calculated.
Aupuni Mōʻī Hui Pū ʻia	15% for articles wholly smelted/cast or melted/poured in the UK	Tied to the U.S.–UK Economic Prosperity Deal; documentation of melt-and-pour or smelt-and-cast origin is essential.
Lukia	200% ad valorem on aluminum	Applies to Russian-origin aluminum and aluminum smelted or cast in Russia, regardless of where it is later processed.
All other origins	Standard 50%/25% tiers	No blanket exemption; China-origin goods face the full tiered structure plus any applicable Section 301 duties.

For goods moving under USMCA, the shift to taxing only non-U.S. content is genuinely favorable for supply chains that already source a meaningful share of their steel or aluminum domestically — but it raises the documentation bar considerably, since the importer now has to substantiate exactly how much of the article’s value is non-U.S.-origin metal, not simply declare a country of manufacture.

What This Means on the Ground for Freight Forwarders and Importers

For a forwarder booking ocean or ke ea ukali out of China, Section 232 rarely shows up as a single dramatic event. It shows up as a string of smaller frictions: a client asking whether a new SKU is covered before committing to a purchase order, a customs broker flagging that a shipment’s HTS code changed between quote and filing, a warehouse manager asking whether goods can sit in bond while a classification question gets resolved. Multiply that across a book of hundreds of SKUs moving weekly, and duty management becomes as much a part of the job as booking space and tracking transit time.

The practical effect is that landed-cost accuracy now depends on information that used to live entirely with the customs broker moving upstream, into the sourcing and booking conversation. A forwarder who can tell a client, at the point of quoting, that a given product falls into the 25% derivative tier rather than the 50% wholly-metal tier — or that it qualifies for the 15% reduced rate as HVAC equipment — is delivering real value beyond moving boxes. Conversely, a forwarder who cannot answer that question leaves the client exposed to a landed cost that may be 25 to 50 percentage points higher than expected, discovered only after the goods have sailed.

There is also a cash-flow dimension that gets less attention than the headline rates. Duties on the full customs value, assessed at entry, mean importers are fronting a much larger sum per shipment than they were under the old metal-content-only calculation. For businesses running on tight working capital, the timing of duty payment relative to inventory sell-through has become a planning variable in its own right, which is part of why bonded and foreign-trade-zone storage options have drawn renewed interest this year.

Compliance Tactics Worth Building Into Your Routing

Classify Early, Not at the Last Minute

Because coverage turns on precise HTS subheadings, the single highest-value habit a shipper can adopt is getting a binding or at least well-documented classification before goods are produced, not after they arrive at the port. A pre-shipment classification review catches the cases where a small design or material change would move a product between tiers, while there is still time to adjust sourcing or packaging.

Document Country of Origin and Melt-and-Pour Data

With the UK’s 15% rate tied to melt-and-pour or smelt-and-cast origin, and USMCA’s non-U.S.-content calculation requiring granular sourcing data, mill certificates and supplier declarations are no longer paperwork filed away for audits — they are the documents that determine which rate applies at entry. Building a habit of collecting this data from mills and component suppliers before goods ship saves weeks of delay later.

Use Bonded Warehousing and FTZs Where They Fit

Holding inventory in a bonded warehouse or foreign-trade zone defers the duty payment until goods are formally entered into U.S. commerce, which can smooth cash flow for importers managing seasonal demand or awaiting a classification ruling. It is not a way around the tariff, but it is a legitimate way to control when the bill comes due.

Model Landed Cost Before Committing to a PO

Given how often rates and product lists have shifted over the past year, a landed-cost model that is not rebuilt every quarter will quietly go stale. Rerunning duty exposure against the current annexes before placing a purchase order, rather than after the goods are already in production, has become a basic risk-management step for anyone sourcing metal-containing goods from China or elsewhere.

How Topway Shipping Helps Shippers Navigate the Section 232 Maze

Since 2010, Topway Shipping has been headquartered in Shenzhen and focused on cross-border e-commerce logistics between China and the United States, which puts the company in the middle of exactly the shipments most affected by this year’s Section 232 changes. The founding team brings more than 15 years of combined experience in international logistics and customs clearance, with China–U.S. transportation as a core specialty — the trade lane where tariff volatility has been most acute.

That specialization matters more than it might sound. A generalist forwarder handling dozens of trade lanes rarely has the bandwidth to track every Section 232 annex revision in detail, let alone map it against a specific client’s product catalog. A team whose daily work is concentrated on China–U.S. freight, by contrast, ends up watching these proclamations as a matter of routine business rather than occasional research, which is precisely the kind of attention this program has demanded over the past two years.

In practice, that experience translates into support across the full logistics chain: first-leg transportation out of Chinese factories, overseas warehousing in the United States, customs clearance handling, and last-mile delivery to the end customer. Because Topway Shipping’s team works with these HTS classifications and clearance filings routinely, clients get an early read on whether a given product is likely to fall into the 50% wholly-metal tier, the 25% derivative tier, or a reduced-rate category — information that is far more useful before a purchase order is placed than after a shipment is held at the port.

Topway Shipping also offers flexible full-container-load and less-than-container-load ocean freight services from China to major ports worldwide, giving shippers room to consolidate smaller derivative-product orders into cost-efficient FCL bookings or move urgent volumes via LCL without waiting to fill a container. Paired with overseas warehousing, that flexibility lets clients hold inventory closer to the U.S. market and manage the timing of customs entry — a genuine advantage in a duty environment where the rate applicable to a product can change between the day it is manufactured and the day it clears customs.

Looking Ahead Through 2027

The reduced 15% rate for agricultural equipment, HVAC systems, and select machinery is explicitly set to run through December 31, 2027, which gives importers in those categories a planning horizon — but only for that specific list. Nothing in the pattern of the past year suggests the broader program has settled into a stable state. Each proclamation so far has both added and removed products, adjusted thresholds, and recalibrated country treatment, often within a matter of months of the previous change.

For anyone sourcing steel-, aluminum-, or copper-containing goods from China or elsewhere, the safest assumption for the year ahead is that the current rate and coverage table is a snapshot, not a fixed rule. Building review cycles — quarterly at minimum — into sourcing and customs processes is no longer an optional best practice; it is close to a requirement for keeping landed costs predictable in a program that has changed roughly every quarter for the past two years.

It is also worth watching how Section 232 interacts with the other tariff tools running in parallel — Section 301 duties on Chinese-origin goods, the global Section 122 tariff, and product-specific programs covering automobiles and semiconductors. These regimes generally do not stack on top of one another for the same article, but figuring out which one governs a given shipment requires the same classification discipline discussed above. A product that dodges Section 232 coverage entirely may still land under a different tariff line, so a full landed-cost picture has to account for the whole stack, not just the metals program in isolation.

Panina

Section 232 has grown from a narrow national-security measure into one of the broadest and most frequently revised tariff programs U.S. importers deal with. The shift to full-value duty assessment, the widening derivative product list, and the patchwork of country-specific caps all point the same direction: classification accuracy and documentation discipline now matter as much as the freight rate itself when calculating what a shipment actually costs to land. Forwarders and logistics partners who track these changes closely — and who can translate a proclamation’s fine print into a practical routing and clearance strategy — are becoming a genuine part of a shipper’s risk management, not just a booking service.

FAQs

Q: Does Section 232 apply to shipments from every country, or only certain origins?

A: It applies globally by default. Certain partners, including the EU, UK, Japan, Korea, and USMCA members, receive reduced or recalculated treatment under bilateral arrangements, but there is no blanket exemption for any major sourcing country, including China.

Q: How is the duty calculated now compared to before April 2026?

A: Since April 6, 2026, Section 232 duties are assessed on the full customs value of a covered article, not just the value of its steel, aluminum, or copper content, which is why per-shipment duty exposure has risen sharply for many importers.

Q: How do I know if my product counts as a “derivative” under Section 232?

A: Coverage is determined at the HTS subheading level based on whether the covered metal is a significant share of material cost and whether the item isn’t itself a raw mill product; a pre-shipment classification review is the most reliable way to confirm status.

Q: Can duty payment be deferred while a classification is being resolved?

A: Bonded warehouses and foreign-trade zones allow importers to hold goods without immediately entering them into U.S. commerce, deferring the duty payment date, though the tariff itself still applies once goods are formally entered.

Q: Is the current rate structure likely to stay stable through 2027?

A: Only the 15% reduced rate for select equipment categories has a stated end date of December 31, 2027; the rest of the program has been revised roughly every few months over the past two years, so ongoing monitoring is advisable.
