Refined copper tariffs: pending, priced in, and what happens next
As of September 11, 2026, no refined-copper tariff is in effect: the White House decision is still pending, so nothing is collectible. LME copper set a record $14,875/t on Sept 10 before falling 3.1%, and COMEX futures dropped over 4%. Next: watch the Federal Register for a proclamation.

The refined-copper question is the only open item. Copper that is already dutied — semi-finished articles, derivatives — is dutied today and is not waiting on this decision.
At a glance
- In force today: nothing new on refined copper. No instrument imposes a duty, so none is collectible.
- Why the market cared anyway: the rally to record prices ran into the expected decision, and the trade unwound in one session when it did not arrive.
- What was priced in cannot be measured publicly — no outlet decomposes the price into a tariff premium versus fundamentals, so this page gives a scenario, not a "priced-in" percentage.
- What to watch: a Federal Register proclamation. That document, not the news cycle, changes your bill.
What happened: the decision that hasn't arrived
On September 10, 2026 at 11:33 AM, Reuters reported — citing two people familiar with the matter — that the White House had not decided on refined copper tariffs:
"The White House has not yet made a decision on refined copper tariffs as officials juggle concerns that higher prices for the red metal could raise manufacturing costs against the potential benefits of encouraging more domestic mining."
A White House official said the administration "had not made a final decision on the tariffs," adding that it "continues to evaluate all options to reshore copper and other critical manufacturing back to the United States." The same official confirmed Commerce did deliver its update to the President by the June 30, 2026 deadline. Not a missed deadline — an unmade decision.
Nothing accompanied the report: no proclamation, no Federal Register notice, no Commerce determination, and no change to the tariff schedule on September 10. As Tech Times put it, importers should "monitor the Federal Register for the proclamation that, as of today, does not yet exist."
One caveat: why the decision stalled is the least-documented part of the story. The affordability element rests on that single anonymous-source report — no Federal Register notice, White House statement or second outlet has put a name or a date to it. Treat the reason as unconfirmed; treat the absence of a decision as confirmed twice over.
The price move: three records, then a reversal
| Date (2026) | Instrument | Level / move |
|---|---|---|
| Sep 7 | LME 3-month copper | $14,533/t, +0.8%, beating the January record — first record of the run |
| Sep 8 | LME 3-month copper | $14,617/t touched — a second intraday record in a row; COMEX futures ≈ $6.85/lb |
| Sep 10 | LME 3-month copper | All-time high $14,875/t, then -3.1% to $14,312/t |
| Sep 10 | COMEX October futures | -4%+ intraday, ≈ $6.585/lb |
| Sep 10 | Freeport-McMoRan (FCX) | -8% pre-market, closed -8% at $70.43; Southern Copper -7%; Teck -7% |
| Sep 10 | COPX copper miners ETF | closed -4.68% at $90.85 |
| Sep 11 | LME 3-month copper | ≈ $14,230/t; first weekly loss since June, week ≈ -1.6% |
The record is $14,875/t, set during the September 10 session — not $14,617/t, which was the September 8 record and is still widely quoted as the high. The sequence is what matters: successive records into the expected decision, then a reversal in the session the "no decision" report landed. Positioning shows in the trade data too — US imports of refined copper and copper alloys hit 225,094 metric tons in July 2026, a single-month high since 1990.
How much of the duty is already priced in?
Less than a number, more than nothing.
What the evidence supports
The rally was tariff-linked, and the outlet that tracks the trade says so plainly: in Scrap Monster's weekly market report, the September 10 reversal followed reports of no decision, and the expectation "had contributed to the premium in U.S. copper markets earlier in the week." A premium that tariff expectations contribute to is, in part, a tariff expectation — and when the expectation weakens, that part of the price comes out.
What no source supports
Nothing published decomposes the copper price into "tariff premium" versus fundamentals. Any page quoting a specific priced-in percentage is estimating, not measuring. Model the duty mechanically instead, below.
Why the stall caused a selloff
A pending duty supports two behaviours: paying up for metal that may become expensive, and holding metal inside the United States where it may fetch a premium. Reuters describes the consequence: "The tariff uncertainty is also preventing copper from flowing to markets outside the U.S., further tightening global supply." When the decision fails to arrive, the first behaviour loses its justification and the second is marked down — a fast, concentrated unwind, exactly as September 10 shows. That reprices probability; it is not a verdict that no duty will come.
If the duty lands: the scenario
Worked example: 20 tonnes of refined copper cathode
Assumptions: 20 tonnes of refined copper cathode at $14,230/t (the September 11, 2026 LME 3-month level); US transaction value, excluding international freight and insurance; one ad valorem rate on the dutiable value; no stacking; no change in FX, brokerage or financing.
| Duty rate | Dutiable value (20 t) | Duty | Landed cost | Move vs 0% | Duty per tonne |
|---|---|---|---|---|---|
| 0% (today) | $284,600 | $0 | $284,600 | — | $0 |
| 10% | $284,600 | $28,460 | $313,060 | +10.0% | $1,423.00 |
| 15% (recommended, not adopted) | $284,600 | $42,690 | $327,290 | +15.0% | $2,134.50 |
| 25% | $284,600 | $71,150 | $355,750 | +25.0% | $3,557.50 |
| 30% (2028 phase-in step) | $284,600 | $85,380 | $369,980 | +30.0% | $4,269.00 |
So: if the duty lands at 15%, landed cost on this shipment moves from $284,600 to $327,290 — up $42,690, or 15.0%. An ad valorem duty is a straight percentage of the customs value, so the percentage move equals the rate and the dollar move scales with the price of the metal.
That last point is the one importers under-model: the duty base moves with the market. At the September 10 peak of $14,875/t, a 15% duty on the same 20 tonnes would have been $44,625 rather than $42,690 — $1,935 more on the same shipment, with no rate change at all.

What happens next
- The Federal Register is the trigger. A proclamation or notice is the only thing that makes a refined-copper duty collectible. Until one is published, the answer to "what do I owe?" is nothing.
- 15% is a recommendation, not a schedule. Reuters reports the President tasked Commerce Secretary Howard Lutnick with recommending whether to impose 15% from January 1, 2027, rising to 30% in 2028. Calling that "coming in 2027" skips a step: it must be decided and published first.
- The derivative track is separate. BIS took comments through August 27, 2026 on adding 14 more derivative articles to Section 232 scope — not a refined-cathode measure.
- This page is built to flip. The moment a decision is published, this status log gets the instrument number, rate, effective date and the calculator's new default.
Don't over-apply this page
Copper is not untreated. Semi-finished copper products and copper-intensive derivatives have carried Section 232 duties since August 1, 2025 — 50% on articles made of the metal, 25% on derivatives, 15% on a reduced tier. Canada's September 8 counter-tariff list runs the other way and puts 50% on US-origin refined copper wire (HS 7408.11.10, .20, .30 and 7408.19.00). If your shipment is a semi-finished article, a derivative, or a US copper-wire export to Canada, the duty is already on the books. This page's pending status covers refined cathode, anode and concentrate only.
Two questions importers are asking
Is the copper tariff in effect?
No. As of September 11, 2026 the White House has not decided, and no Federal Register instrument imposes a refined-copper duty — so nothing is collectible.
What will the rate be if it lands?
Unknown. The recommendation on the table is 15% from January 1, 2027, rising to 30% in 2028 — recommended, not adopted.
