The buyer quotes ₹31,800/MT. You push for ₹32,500. He says no. You think he’s just negotiating.
He isn’t. At least not entirely.
There’s a calculation running in the background of every scrap rate a mill quotes. Understanding that calculation – how it works, what feeds into it, what changes it – is the difference between a seller who negotiates from a position of knowledge and one who argues from frustration.
Here’s exactly how steel plants decide what they’ll pay for your scrap.
Start Here – What a Steel Plant Actually Needs From Scrap
A mill doesn’t buy scrap. It buys molten steel – in solid form, for now.
Every buying decision starts with one question: how much usable liquid steel will this lot produce per tonne of input? That percentage is called metallic yield – and it drives everything else.
| Scrap Grade | Typical Metallic Yield | What Mill Pays Premium For |
|---|---|---|
| Shredded Scrap | 97 – 98% | Highest yield – commands top rate |
| CR Busheling (Loose) | 95 – 97% | Clean, dense, consistent |
| HMS 1 (80:20) | 92 – 94% | Benchmark grade for most mills |
| HMS 2 | 88 – 91% | Lower yield – lower price |
| LMS (Light Melting) | 82 – 87% | Thin material, significant melt loss |
| CI (Cast Iron) | 80 – 85% | Different melt behavior, priced separately |
| Turning / Boring | 78 – 84% | Oil contamination reduces yield further |
| Mixed / Unsorted | 75 – 82% | Widest variance – priced at lowest assumption |
Every ₹1,000/MT difference between HMS 1 and HMS 2 is not arbitrary. A 2% yield difference at ₹50,000/MT finished billet cost translates to roughly ₹1,000/MT difference in raw material value. The math is precise. The rate reflects it.
The Basic Rate Formula Mills Use
Mills don’t just look at global prices and guess. There’s a working calculation.
Scrap Buying Rate = (Finished Billet Price × Metallic Yield) – Conversion Cost
Break that down:
- Finished billet price – what the mill can sell its output for today
- Metallic yield – what percentage of your scrap becomes usable steel
- Conversion cost – electricity, labour, furnace wear, flux, slag disposal
Quick example at current February 2026 numbers:
| Factor | Number |
|---|---|
| Billet price (ex-mill) | ₹45,000/MT |
| HMS 1 metallic yield | 93% |
| Gross raw material value | ₹41,850/MT |
| Conversion cost (IF furnace) | ₹8,500 – ₹10,000/MT |
| Maximum scrap buying rate | ₹31,850 – ₹33,350/MT |
That’s the ceiling. The mill won’t pay more than that and stay profitable. Everything within that range becomes a negotiation based on supply, competition, and urgency.
This is why when billet prices rise ₹1,000/MT, scrap rates typically follow within 24 – 48 hours. The formula moves automatically.
Factor 1 – Billet and TMT Prices
This is the upstream trigger everything else follows.
When construction demand picks up – post-monsoon season, large infrastructure orders, housing projects – TMT rebar prices rise. Mills push output. Billet prices rise. The gross raw material value in the formula goes up. Scrap buying rates follow.
The reverse is equally true. Flat construction season. Slow TMT demand. Billet prices soften. Mills don’t need to fill furnaces urgently. Scrap bids drop. Buyers become selective.
Track billet prices on SteelMint or SteelMarketPrice before your next major sale. When billet is rising, sell. When it’s flat or falling, hold if you can.
Factor 2 – DRI and Sponge Iron Prices
This is the substitution factor – and it’s the one most sellers don’t fully understand.
Indian induction furnaces can charge their furnaces with a mix of scrap and DRI (Direct Reduced Iron / sponge iron). The ratio varies by mill – some run 60:40 scrap to DRI, some run 80:20, some run pure scrap heats depending on the steel specification required.
When DRI prices fall, mills substitute more sponge iron into the furnace burden. Less scrap needed. Buying interest drops. Rates soften.
When DRI prices rise – or supply tightens – mills chase scrap harder. Buying interest spikes. Rates follow.
Central and Eastern India mills in particular run high metallics ratios – sometimes 90% DRI, 10% scrap – because coal-based sponge iron is locally accessible and cheaper. In those regions, scrap demand is structurally lower. Which is exactly why Jalna and Maharashtra – with lower DRI dependency – tend to offer better scrap rates for HMS grades than parts of Chhattisgarh or Odisha.
Factor 3 – Import Parity Pricing
Indian mills don’t just compare your scrap against the mill next door. They compare it against the global market.
The benchmark is imported HMS 1 (80:20) arriving at Indian ports – primarily Mumbai, Chennai, and Nhava Sheva. When US East Coast or UK HMS prices drop globally and landed import cost comes down to, say, ₹30,500/MT – that becomes the ceiling on domestic offers. Why would a mill pay ₹32,000/MT for domestic material when they can import at ₹30,500?
The landed import price sets the floor of what domestic sellers must beat on quality and logistics advantage.
When global scrap prices rise – as they did through mid-2025 – import costs rise too. The domestic ceiling lifts. Your rate goes up with it. When global prices fall, the ceiling drops fast.
This is why sellers in port-adjacent markets like Mumbai and Chennai feel the impact of global price moves faster than sellers in landlocked Marathwada.
Factor 4 – Local Supply and Buyer Competition
Same grade. Same day. ₹500/MT difference between two buyers in the same industrial area.
How? Simple supply dynamics.
If three other trucks arrived at Mill A before yours and the furnace is partially loaded for the day’s heat, the buyer’s urgency is low. He bids conservative. If Mill B next door hasn’t received any deliveries yet and has a heat scheduled for this evening – they need your material. Their bid goes up.
Local supply density directly affects your negotiating position hour by hour. This is why calling multiple buyers before confirming a deal isn’t just good practice – it’s the only way to find where demand is highest at that specific moment.
Mills in industrial clusters like Jalna buy roughly 30 lakh tonnes of scrap annually across the collective furnace network. On any given day, some furnaces are full, some are hungry. The one that’s hungry pays more.
Factor 5 – Grade-Specific Premiums and Discounts
Mills maintain an internal rate card. The basic price – usually benchmarked to HMS 1 (80:20) at 92-94% yield – is the reference point. Every other grade trades at a premium or discount from that base.
| Grade | Typical Spread vs HMS 1 Base |
|---|---|
| Shredded Scrap | +₹3,000 – ₹4,000/MT |
| CR Busheling (Loose) | +₹2,000 – ₹3,000/MT |
| Railway Scrap | +₹4,000 – ₹5,000/MT |
| HMS 1 (80:20) | Base rate |
| HMS 2 | -₹500 – ₹700/MT |
| LMS | -₹1,500 – ₹2,500/MT |
| CI Scrap | -₹1,500 – ₹2,000/MT |
| Turning Scrap (oily) | -₹2,000 – ₹3,000/MT |
| Mixed Unsorted | -₹2,000 – ₹3,500/MT |
These spreads are consistent across markets because yield math is consistent. The absolute number changes by city. The relative relationship between grades stays roughly the same.
Knowing the actual value difference between HMS and cast iron scrap tells you exactly where your material sits on this scale before you walk into any negotiation.
Factor 6 – Lot Size and Consistency
A 5-tonne lot and a 200-tonne lot of identical grade get quoted differently. Not because the buyer is arbitrary – because large consistent supply has real value to a mill.
- Small lots (under 5MT): 5 – 10% below market rate. Handling cost per tonne is higher. Testing cost per tonne is higher. Not worth full rate.
- Standard lots (10-25MT): Par market rate. Standard truck, standard deal.
- Large lots (50MT+): Sometimes +2 – 3% above market. Mills value reliable large supply – it reduces procurement overhead and stabilizes their furnace scheduling.
- Regular supply contracts (100MT+ monthly): Premium pricing and faster payment cycles in many cases.
Volume matters. Consistency matters more. A mill that can count on 100 tonnes from you every month will pay better and fight less on grade than one who sees you twice a year.
Factor 7 – Payment Terms and Cash Flow
This one runs quietly in the background of every rate quote.
Immediate payment after delivery – same day or next day – is the standard in active scrap markets like Jalna. Buyers who offer immediate payment have slightly more negotiating room to offer better rates because sellers accept them over slower-paying competitors.
When a buyer asks for 7-day or 15-day payment terms, the effective rate they’re offering is lower – even if the number on paper looks the same. The time value of money in a business running on working capital is real.
Always clarify payment terms before the rate negotiation ends. A ₹31,800/MT immediate-pay offer beats a ₹32,200/MT seven-day-pay offer for most sellers who need to turn working capital quickly.
What This Means for You as a Seller
Once you understand the formula, the market stops feeling random.
Billet prices rising? Your rate ceiling just moved up. Wait a day before calling buyers.
DRI prices falling? Mills are substituting away from scrap. Don’t expect strong bids. Move material if you have cash pressure, hold if you don’t.
Import parity dropping? Global scrap went cheap. Domestic ceiling just dropped too. Don’t fight the market on price – focus on grade quality instead.
Local furnace running a hot schedule tonight? That mill needs material urgently. Their bid will be at the top of their range. Call them first.
Understanding the signals dealers use that most sellers never see adds another layer to this – the buyer-side psychology that runs alongside the formula.
The Seller’s Edge
Most sellers negotiate on instinct. They push back when a quote feels low, accept when it feels reasonable, and have no real basis for either position.
The sellers who consistently get rates at the top of the market range do it differently. They track billet prices. They know when DRI is cheap. They call multiple buyers. They understand yield math well enough to know when a grade premium is justified and when a discount is wrong.
That knowledge doesn’t take years to build. It takes understanding the formula – and the iron scrap purity factors that directly affect where your material lands on the yield table – before the next deal.
Rate calculations and yield figures referenced are based on standard Indian induction furnace industry practices as of February 2026. Actual mill buying criteria vary by furnace type, steel specification, and regional market conditions.
