ADC12 Price Outlook: Tax Audits Erase Recycled Alloy’s Discount

A recycled alloy is supposed to be the cheaper option. Yet on 15 October 2026, ADC12 die-casting alloy changed hands at RMB 24,300/t while primary A00 aluminium closed at RMB 23,260/t, according to Shanghai Metals Market (SMM). So why has the ADC12 price outlook become a story about a secondary product that has lost its discount?

The cause sits in tax offices rather than smelters. Intensifying audits in central China have made invoice-compliant scrap hard to find, and that scarcity is now feeding directly into alloy costs.

This matters well beyond Chinese die-casters. If you track aluminium cost curves, automotive alloy demand or recycler economics, the compliance squeeze is quietly changing who holds pricing power in the chain.

Here is what holds ADC12 up, what caps it, and which signals would tell you the alloy is about to break out of its expected RMB 24,000-24,600/t range.

Why compliant scrap has become the scarcest input in China’s aluminium chain

The first oddity shows up in the scrap yard. When A00 fell RMB 500/t in the week to 15 October, scrap prices followed it down but refused to fall as far.

That resilience has little to do with how much scrap exists. It has everything to do with paperwork.

Recyclers need valid value-added tax (VAT) invoices to claim input-VAT credits, which are deductions for tax already paid on the materials they buy. Scrap without a compliant invoice is worth less to a recycler, because it carries a tax cost that cannot be recovered. The real constraint is therefore invoice-compliant scrap, not scrap volume.

What changed in 2026

The rulebook itself is not new. The key policy facts are:

• State Taxation Administration Announcement No. 5 of 2024, effective 29 April 2024, lets qualified recycling enterprises issue VAT invoices on behalf of individual scrap sellers, a practice known as reverse invoicing.
• Each individual seller faces a RMB 5 million cap on cumulative sales over a rolling 12 months.
• Golden Tax Phase IV, China’s data-driven tax enforcement system, intensified in 2026; Mysteel reports restrictions or suspensions in Hubei, Anhui, Jiangxi and other regions.

What changed is enforcement, not the law. There has been no nationwide abolition of reverse invoicing, only tighter policing and uneven application from province to province.

Tax compliance inspections across Henan, Hunan and neighbouring provinces began tightening in September, and secondary producers were already caught between thin invoice supply and weak orders before the October peak season disappointed.

The audit squeeze in numbers SMM reports that some firms in central China can currently issue only about 20% of their invoice quotas.

How long it may last

SMM sees no near-term easing and names audit scope and intensity as the main variable. Mysteel has gone further, describing the restrictions as structural rather than seasonal, though that view and a separate report that Shandong considered suspending reverse invoicing have not been independently confirmed.

No source gives a date for restored quotas. For you, that means scrap prices now respond to enforcement headlines almost as much as to moves in the aluminium price itself.

How a squeezed scrap spread pushes ADC12 above primary aluminium

If the scarcity is regulatory, the next question is how it reaches the alloy price. The answer runs through one number: the spread.

The spread is simply the A00 price minus the scrap price. It measures how much cheaper scrap is than the primary metal it replaces, which is scrap’s nominal cost advantage.

SMM describes these spreads as historic lows. Its 16 October quote put ADC12 at RMB 24,300-24,500/t, so the 15 October figure is the cleaner comparison for the spread arithmetic.

Follow the numbers through and the chain looks like this:

1. A00 falls faster than compliant scrap, so the spread narrows.
2. Scrap’s raw-material cost advantage erodes, lifting the cost of making ADC12 relative to primary metal.
3. ADC12 loses its traditional discount and can trade at or above A00, as it does now.
4. Primary aluminium or wrought-alloy scrap becomes a cheaper substitute where specifications allow, which places a ceiling on ADC12’s upside.

A shredded-scrap spread of barely RMB 711/t leaves almost no buffer. SMM’s June presentation reportedly showed a similar convergence toward parity in mid-2026, though that precedent remains unverified.

What this tells you is that ADC12 is being held up by cost and scarcity rather than by buyers chasing metal. That makes the price fragile if either support weakens, and it breaks the “recycled is cheaper” assumption baked into many margin models for alloy makers and recyclers.

Demand, inventories and imports: what pushes back on cost support

Cost support is only one side of the rope. The other side is pulled by buyers, and they are not pulling hard.

Supportive forces

Destocking deserves its due. Social inventory of cast aluminium-alloy ingots fell to 25,200 t, down 5,800 t month on month, as producers restarted after the National Day holiday.

Leading secondary producers lifted their operating rate to 52.1%, up 6.5 percentage points from before the holiday, against a September industry rate of 51.0%. Import replenishment also remains limited.

Limiting forces

The resistance is harder to ignore. SMM says the October peak season fell short of expectations, orders improved little and buying stayed need-based, and the 52.1% operating rate still sits below the same period of 2025.

After the holiday, cast-alloy futures fell further than spot prices, widening the basis (the gap between the two). That encouraged suppliers to ship more physical metal, which sped the drawdown but also released spot material into a soft market.

Imports form a latent cap. Overseas ADC12 offers eased to US$3,050-3,130/t, leaving import economics near breakeven, while imported shredded scrap sat at RMB 20,970/t in Ningbo and RMB 21,020/t in Tianjin. A shift in the renminbi, LME prices or freight could open that window quickly.

Imported shredded scrap is the main alternative to domestic material, and the reliability of overseas scrap suppliers in Thailand, Europe and elsewhere determines how quickly that substitute can relieve the domestic invoice shortage.

Earlier in 2026, inventory reportedly built to 28,100 t despite high input costs, an unverified figure that still makes the point. Falling stocks support the price, but with end-demand this soft, destocking alone cannot start a rally.

The ADC12 price outlook: a range, two scenarios and the signals that matter

Put the two forces together and the base case is consolidation rather than a breakout.

SMM’s short-term expected range ADC12 at RMB 24,000-24,600/t, against a current price of RMB 24,300/t.

Weaker cost support and soft demand pull the price down; tight compliant scrap and falling inventories hold it up. The range breaks only if one side clearly wins.

The premium also tends to correct itself. A wide ADC12 premium over A00 invites substitution, alternative scrap grades and imports, each of which drains it.

Ranked by how early they move, the signals worth watching are:

1. The spread and intensity of central-China tax audits.
2. Regional invoice quotas and reverse-invoicing availability.
3. A00-to-scrap spreads by grade.
4. Import breakeven and overseas ADC12 offers.
5. Cast-alloy inventories and operating rates.
6. Downstream automotive and die-casting orders, plus the futures-spot basis.

Treat the range as conditional on policy and import settings, and watch those variables rather than ADC12 alone. No SMM data newer than 16 October 2026 was available.

Past performance does not guarantee future results. Price projections are subject to market conditions and various risk factors, and forward-looking statements may change as the market develops.

What this squeeze changes for aluminium investors, and what it does not

The squeeze changes the source of ADC12’s support. Compliance-driven scarcity, not buyer appetite, now sets the alloy’s floor, while weak orders, substitution and near-breakeven imports set its ceiling.

What it does not change is the demand picture. ADC12 is anchored but capped, and high input costs alone have not delivered sustained upside this year.

The single variable most likely to tip the balance is enforcement and quota policy in central China. If you hold exposure to recyclers, die-casters or aluminium cost curves, watch audit headlines and scrap spreads first, then imports, and judge the price against them.
