Reports Put U.S. July Refined-Copper and Copper-Alloy Imports at 225,094 Metric Tons
Key takeaways
- Reports published September 3 by Wallstreetcn and GateNews, attributing the figure to U.S. Commerce data and Trade Data Monitor, said July U.S. refined copper and copper-alloy imports reached 225,094 metric tons, 78% above June and 8% above July 2025.
- The official Census Bureau/BEA July release, issued September 3, reports seasonally adjusted copper-import value of US$3.214 billion versus US$1.812 billion in June. Its copper table is a dated dollar measure; the tonnage comes from the relayed Trade Data Monitor figure.
- A July 2025 White House proclamation described potential refined-copper duties of 15% from January 1, 2027, and 30% from January 1, 2028, subject to a later determination.
- Reuters' August 25 report, relayed by Investing.com, said COMEX stocks reached 675,185 metric tons through August 25 after 46 consecutive daily increases. CRU's latest cited 2026 projection was a global surplus of 639,000 metric tons.
Trade Data Monitor, as relayed by Wallstreetcn and GateNews, called July's volume the highest in its latest available historical comparison since 1990. That comparison remains a reported historical claim because no downloadable tonnage history was available for independent recomputation.
How the data differ
Census/BEA's July copper-import value rose US$1.402 billion from June. January-through-July value was US$15.207 billion versus US$11.180 billion in the same period of 2025. The dollar measure is seasonally adjusted; product mix and price data would be needed for a tonnage conversion. The official FT900 release reports the dollar measure, while the physical figure is relayed from Trade Data Monitor.
| Measure | Figure | Date and basis |
|---|---|---|
| U.S. refined copper and alloys | 225,094 metric tons | July 2026; reported Commerce/Trade Data Monitor figure |
| Copper import value | US$3.214 billion | July 2026; seasonally adjusted; Census/BEA |
| COMEX warehouse stocks | 675,185 metric tons | Through August 25; Reuters report |
| Global copper balance | 639,000 metric tons surplus | Latest cited 2026 projection; CRU via Reuters |
These rows measure different populations and should be read separately. Total U.S. availability remains unmeasured by them.
Tariff dates and warehouse incentives
The White House proclamation set a 50% duty on specified semi-finished and intensive derivative copper products effective August 1, 2025. For refined copper, it said the president could determine whether phased duties of 15% in 2027 and 30% in 2028 were warranted after a Commerce update. Those dates may shape inventory positioning; the refined-copper duty remained subject to a later determination in that proclamation.
The Reuters-reported COMEX inventory buffer was roughly 675 thousand metric tons (675,185 metric tons), not a U.S. availability total. Reuters put three-month LME copper at US$14,226 per metric ton on September 3, down 0.3% after an intraday low of US$14,092; Tuesday's high was US$14,441.50. The price move is a dated market observation, and its cause remains unestablished.
Three observations will separate demand from positioning
If a further reported import print arrives near 225,094 metric tons alongside rising COMEX stocks, it would be consistent with continued tariff positioning. If a confirmed delay or exemption arrives, liquidation risk would rise and the warehouse arbitrage would narrow. If COMEX stocks fall while non-U.S. premiums firm, physical demand would be absorbing the buffer.
The Australian government's September 2025 Resources and Energy Quarterly provides a precedent for inter-exchange movement and COMEX accumulation during tariff uncertainty, without offering a matched July comparison.
For U.S. fabricators, delivered premiums and inventory days are the near-term read-through. Global traders face COMEX-LME spreads and re-export economics; investors need to distinguish mine exposure from warehouse-location exposure. The strategic conclusion is that tariff policy can regionalize a surplus before it changes global mine supply. The next observable is the August trade release, scheduled for October 6, which will show whether July's import surge persisted.
