Trump copper tariffs have dominated the market conversation, from COMEX stockpiles to the prospect of new duties on refined metal. For copper scrap traders, however, the more immediate compliance question sits elsewhere. Proclamation 10962 directed the US Department of Commerce to implement a 25% domestic-sales requirement for “high-quality copper scrap”, a category the government has still not publicly defined.

The tariff story concerns imported copper products. The scrap provision concerns whether certain US-generated recyclable material may have to be sold domestically before traders pursue export demand.

Trump Copper Tariffs: Key Information

  • Trump copper tariffs currently concern specified copper articles and derivatives. The copper scrap issue sits under a separate Defense Production Act domestic-sales provision.
  • Proclamation 10962 directed Commerce to implement a 25% domestic-sales requirement for “high-quality copper scrap”.
  • Commerce also recommended export controls for high-quality copper scrap, but the proclamation did not create a copper scrap export-licensing regime.
  • “High-quality copper scrap” remains undefined in the public regulatory record.
  • US industry data for 2024 show that roughly 57% of the broad red-metal scrap pool accounted for in domestic consumption and exports already stayed in the US.
  • BIS has since begun rebuilding the administrative machinery needed to issue Defense Production Act allocation orders.

What Proclamation 10962 Actually Says About Copper Scrap

Several copper measures appeared in the same proclamation.

The Section 232 element imposed tariffs on specified semi-finished products and copper-intensive derivatives. The White House excluded copper scrap, ores, concentrates, mattes, cathodes and anodes from those tariffs. The wider tariff regime has since been modified in 2026, including changes to rates and the treatment of copper articles, but the scrap provision remains a separate legal track.

Clause 8 then took a different route. President Trump found that copper input materials and high-quality copper scrap met the criteria for action under Section 101 of the Defense Production Act and directed Commerce to implement the domestic-sales requirements recommended in its June 2025 report.

Commerce had recommended two scrap measures: a 25% domestic-sales requirement and export controls for high-quality copper scrap. Only the domestic-sales requirement received an implementation direction in Proclamation 10962.

The 25% Copper Scrap Domestic Sales Requirement

A 25% domestic-sales requirement is not an export ban, nor does it mean 75% of US scrap must remain at home. It sets a domestic floor. The remaining material could still be exportable, depending on how Commerce writes the rule and any other applicable controls.

The unresolved questions are practical. Would a seller have to complete domestic sales, offer material to US buyers first, or meet the threshold across a monthly or annual portfolio? Would it apply to producers, traders, processors or all three?

Until Commerce answers them, companies cannot reliably model the obligation inside existing contracts.

“High-Quality Copper Scrap” Still Has No Definition

The largest uncertainty is the phrase at the centre of the policy.

ReMA said after the 2025 proclamation that the White House had not defined “high-quality scrap” and that it would work with Commerce to clarify the term. More than a year later, no publicly issued copper-specific allocation order has established a clear operating definition.

Copper is not traded simply as “good” or “bad” scrap. Markets distinguish material by grade, copper content, cleanliness, form, contamination and recognised specifications. Customs systems apply their own classifications.

A trader can describe a load as bare bright wire, No. 1 copper, No. 2 copper, tubing, granules or copper-bearing cable. None of those labels automatically answers whether Commerce would consider it “high-quality” for this rule.

Why US Copper Scrap Export Controls Did Not Happen

The recycling industry argued during the Section 232 process that export restrictions were not justified by domestic supply conditions.

Recycling Today, using USGS and Commerce data, reported that US melt shops consumed 928,000 tonnes of copper-bearing scrap in 2024. Imports accounted for 102,000 tonnes, leaving about 826,000 tonnes of domestically generated material consumed in the US. Exports totalled 614,300 tonnes.

On that broad accounting, around 57% of the combined domestic-consumption-and-export pool stayed in the country, while just under 43% left it.

Those figures supported ReMA’s case against export restrictions, and the White House did not enact the recommended licensing regime. But the data cover a broad red-metal scrap pool, not a legally defined subset called “high-quality copper scrap”.

BIS Is Building the Machinery Behind the Rule

The absence of a copper definition should not be mistaken for inactivity.

In February 2026, the Bureau of Industry and Security sought approval for information collection to support Defense Priorities and Allocations System actions. BIS specifically cited Proclamation 10962 and its copper domestic-sales requirement.

The notice said BIS had not issued an allocation order in more than a decade. It was rebuilding processes for directives, audits and investigations.

In July, the White House created a separate Defense Production Act framework for recoverable critical materials but expressly excluded copper scrap because Proclamation 10962 already covered it. BIS later used that framework to impose a 100% monthly domestic-allocation requirement on black mass and tungsten waste and scrap.

Copper is not covered by that rule. The point is structural: Commerce has shown what a modern scrap allocation regime can look like.

What the 28 September Copper Tariff Decision Could Change

Markets are now treating 28 September as the next major decision point for Trump copper tariffs.

The original proclamation required Commerce to update the President by 30 June 2026 on refining capacity and the US refined-copper market. It left the President to decide whether a phased tariff on refined copper, recommended at 15% from 2027 and 30% from 2028, was warranted.

Reuters reported on 10 September that the White House had not reached a decision. By mid-September, COMEX warehouses held about 696,000 tonnes after months of tariff-driven inflows, while policy uncertainty had distorted the premium between US and London prices. Market participants have been treating 28 September as the expected decision point rather than a copper-scrap implementation date.

Whatever happens to refined copper, it will not automatically create a copper scrap export licence. But a policy that changes US premiums, domestic refining economics or demand for secondary feedstock could alter the commercial case around keeping more scrap in the country.

Why Classification Matters More Than the Headline

This is where the issue moves from commodity policy into transaction execution.

For a cross-border trader, “copper scrap” is never enough information. A shipment has a grade, composition, weight, origin, destination, customs classification and documentary trail. Those details determine whether affected material can be identified quickly.

WasteTrade’s work around structured material records illustrates the point. Its Digital Product Passport approach can associate a batch with material classification, composition, origin, custody information and shipment documentation. That does not decide whether a US regulation applies, but it creates the evidence layer needed to assess and document a material against changing rules.

The problem is not only legal uncertainty. It is the mismatch between a broad regulatory phrase and the categories through which recyclable metals are bought, sold and moved.

What Copper Scrap Traders Should Do Now

Copper scrap traders do not need to predict the final rule to improve their position.

First, tighten classification. Record the grade, copper content, form, contamination and relevant HTS or Schedule B code for each US-origin load.

Second, preserve evidence. Photographs, assays, weighbridge records, origin records, contracts and shipment documents may matter if Commerce draws a boundary between covered and non-covered grades.

Third, build domestic buyer optionality. If a sales allocation becomes operational, knowing which US processors can accept a particular copper grade will matter as much as knowing the strongest export bid. WasteTrade’s marketplace model is relevant here because it gives secondary-material sellers visibility across verified buyer demand while connecting the trade with logistics and supporting documentation.

Finally, review long-dated contracts for change-in-law, government-allocation, cancellation and rerouting provisions. The cost of an undefined rule often appears first as a contractual problem.

The Real Risk Behind Trump Copper Tariffs

Trump copper tariffs are easy for markets to watch because a tariff produces an identifiable rate and an immediate price response. The scrap provision is harder. Traders still do not know precisely which material it covers, how Commerce will measure the 25% requirement or what evidence sellers may have to retain.

Yet the legal authority exists, BIS has built administrative capacity around it, and the White House reaffirmed in 2026 that copper scrap remains covered under Proclamation 10962.

That is why Trump copper tariffs should not be the only US copper policy on a scrap trader’s screen. Price risk can often be hedged. An undefined compliance boundary is harder to manage after a cargo has already been bought, sold and booked for export.
