What happened
China's copper scrap suppliers kept releasing material into the market on September 7 even as prices held near record territory, according to Shanghai Metals Market (SMM)'s daily secondary copper review. The Shanghai Futures Exchange (SHFE) copper contract closed at 109,630 yuan a tonne, up 30 yuan from the previous session, with traders telling SMM that copper prices would face significant resistance trying to break back above 110,000 yuan in the near term -- prompting suppliers to sell into the strength rather than hold out for a further rally. The spread between copper cathode and copper scrap narrowed to 3,577 yuan a tonne, up only slightly from the day before but down sharply from a self-described "historical extreme" of 5,533 yuan a tonne hit on August 17. SMM described secondary copper raw material supply as relatively ample in the short term, even as separate SMM reporting this week flagged that rising invoice compliance costs have been squeezing the amount of properly tax-documented scrap reaching the market since August.
The details
The headline number in SMM's September 7 review isn't really the SHFE close of 109,630 yuan -- it's the shrinking gap between that price and what copper scrap is fetching. Three weeks earlier, on August 17, the spread between copper cathode and copper scrap hit what SMM itself called a historical extreme of 5,533 yuan a tonne. By September 7, that spread had compressed to 3,577 yuan, even though the underlying copper price hadn't fallen at all. A shrinking cathode-scrap spread normally means one thing: scrap is getting relatively more expensive to buy, which should be good news for anyone recycling copper into secondary rod. What's actually happening is more complicated.
The complication is a tax and invoicing squeeze that has nothing to do with the copper price itself. Over the course of August, the tax-inclusive invoice rate that secondary copper material has to carry to be considered compliant supply climbed from 10.5% to a range of 11.5% to 12%, reaching the top of that range in Guangdong -- one of China's largest scrap-trading hubs. SMM's own reporting this week described the resulting market as one of "high spreads, low transaction volumes" and "strong invoice constraints," noting that scrap enterprises competing for the tax paperwork needed to move material legally have kept compliant supply tight even while overall scrap volumes reaching the market stay, in SMM's words, "relatively ample." That's the reconciliation: there's no shortage of raw scrap changing hands, but a shrinking share of it comes with the invoice documentation buyers need, and that compliance friction is eating into the margin advantage that made scrap cheaper than new cathode in the first place.
On the other side of the trade, downstream demand is doing exactly what you'd expect when absolute prices sit near records: not much. SMM's purchasing sentiment index read 1.80 on September 7, barely up from 1.73 in late August, while suppliers' willingness to sell held firm in the high 2s throughout the same period. Secondary copper rod producers and the wire-and-cable manufacturers who buy from them have been described in SMM's daily commentary as fearful of high prices and limiting orders to just-in-time volumes rather than building inventory. China's copper scrap imports still rose to 219,100 tonnes in July, up 3.89% month-on-month, so the raw material is arriving -- it's converting that material into finished product that buyers are hesitant to commit to at current levels.
Put together, this is a market where every participant is behaving rationally but pulling in different directions. Suppliers are selling because prices near 110,000 yuan are worth locking in now. Buyers are holding back because the same price makes forward commitments risky. And the compliance regime sitting underneath both of them means the price signal buyers and sellers are reacting to isn't quite the clean cathode-versus-scrap arbitrage it looks like on paper -- it's one already distorted by how much of the available scrap can actually be invoiced.
Why it matters
China is the world's largest copper consumer and smelter base, so how its domestic scrap and cathode markets are trading -- suppliers releasing material while buyers hold back, and compliance costs quietly eating into scrap's price advantage -- is a real-time read on Chinese demand that feeds into the same global copper balance Indian recyclers, secondary-rod producers and traders watch when they price scrap and cathode off international benchmarks.
Our read
Outlook: neutral. Copper prices on the Shanghai Futures Exchange are consolidating just below the 110,000-yuan level traders see as near-term resistance, with scrap suppliers selling into the strength and downstream buyers holding back -- a balanced tug-of-war between supply willing to sell at current levels and demand wary of committing to them, rather than a clear directional signal.
What to watch
- Whether SHFE copper breaks above the 110,000-yuan level that traders currently see as a resistance point
- The copper cathode-to-scrap spread, to see whether it keeps narrowing from September 7's 3,577 yuan or stabilizes
- Further changes to tax-inclusive invoice requirements for secondary copper materials, currently in the 11.5%-12% range
- China's monthly copper scrap import volumes, which rose to 219,100 tonnes in July

Timeline
- 2026-07: China's copper scrap imports rise to 219,100 tonnes, up 3.89% month-on-month.
- 2026-08-17: The copper cathode-to-scrap price spread hits a self-described historical extreme of 5,533 yuan a tonne.
- 2026-08-26: Guangdong copper cathode inventory falls for a seventh consecutive day as suppliers hold prices firm and keep selling.
- 2026-08: Tax-inclusive invoice rates required for compliant secondary copper material climb from 10.5% to 11.5%-12%, reaching 12% in Guangdong.
- 2026-09-07: SHFE copper closes at 109,630 yuan a tonne; the cathode-scrap spread narrows to 3,577 yuan as scrap suppliers continue selling into price strength.
Demand Drivers
Downstream secondary copper rod and wire-and-cable manufacturers have kept procurement limited to just-in-time volumes, wary of committing to inventory with copper prices near record levels; SMM's purchasing sentiment index read just 1.80 on September 7, only modestly above 1.73 in late August.
Supply Drivers
China's copper scrap imports rose to 219,100 tonnes in July, up 3.89% month-on-month, and SMM described secondary copper raw material supply as relatively ample in the short term as suppliers sold into elevated prices.
Inventory Drivers
Copper cathode inventory in Guangdong, a major South China trading hub, fell for seven consecutive days in late August as arrivals slowed, even as suppliers held prices firm and continued selling.
Government Policies
Tax-inclusive invoice rates required for compliant secondary copper material climbed from 10.5% to a range of 11.5% to 12% during August, reaching 12% in Guangdong -- a compliance-cost increase that has tightened the supply of properly documented scrap independent of the copper price itself.
What could lift prices
- SHFE copper closed at a fresh multi-week high of 109,630 yuan a tonne on September 7, up from the previous session
- China's copper scrap imports rose to 219,100 tonnes in July, up 3.89% month-on-month, showing continued raw material inflow despite high prices
- Purchasing sentiment ticked up modestly to 1.80 from 1.73 in late August, a small sign of downstream buyers adjusting to the higher price regime
What could weigh on prices
- Traders told SMM that copper prices would face significant resistance trying to break back above 110,000 yuan, prompting suppliers to sell into strength rather than hold for further gains
- Downstream purchasing sentiment remains weak at 1.80, well below the scrap-selling sentiment index near 2.82, showing buyers are far more reluctant than sellers
- Rising invoice compliance costs (10.5% to 11.5%-12% during August) are squeezing the supply of properly documented scrap and eroding scrap's price advantage over new cathode
Country impact
| Country | Impact | Reason |
|---|---|---|
| China | High | As the world's largest copper consumer and secondary-copper market, China's scrap-selling and cathode-buying behavior on the Shanghai Futures Exchange directly reflects how domestic demand is absorbing near-record copper prices. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Copper Recycling | Positive | Scrap suppliers are capturing elevated prices by selling into the current strength, but a narrowing cathode-scrap spread and rising invoice compliance costs are eroding the margin advantage that makes scrap cheaper than newly refined cathode. |
| Wire and Cable Manufacturing | Negative | Manufacturers buying secondary copper rod have limited procurement to just-in-time volumes, wary of committing to inventory while copper prices sit near record levels. |
Who gains, who loses
- Copper scrap suppliers with compliant, properly invoiced material: Suppliers able to sell tax-compliant scrap are capturing near-record prices while a tightening compliance regime limits competing supply from less-documented sources.
- Secondary copper rod and wire-and-cable manufacturers: A narrowing cathode-scrap spread combined with rising invoice compliance costs reduces the cost advantage of using scrap, while high absolute copper prices are keeping these buyers limited to just-in-time procurement.
Other ways this could play out
- If SHFE copper breaks decisively above 110,000 yuan despite the resistance traders are currently citing, scrap suppliers may pull back on sales in anticipation of further gains, tightening near-term scrap availability
- If invoice compliance costs continue climbing beyond August's 11.5%-12% range, the shrinking cathode-scrap spread could compress further, weakening the economic case for secondary copper rod producers to favor scrap over new cathode
Price risks
- Continued compression of the cathode-scrap spread could discourage further scrap supply from reaching the market if the price advantage over new cathode keeps shrinking
- A further rise in invoice compliance costs could restrict compliant scrap supply independent of underlying copper price moves
- Persistently weak downstream purchasing sentiment could keep secondary copper rod demand subdued even if copper prices consolidate rather than fall
Historical comparison
- August 17, 2026 (spread peak): The copper cathode-to-scrap spread has narrowed from a historical-extreme 5,533 yuan a tonne on August 17 to 3,577 yuan by September 7, even though the underlying SHFE copper price kept climbing over the same period.
