Bare bright (Millberry / ISRI Barley) — discount band
Millberry — bare bright 99.95% Cu wire — trades at the tightest discount to LME because it is the closest scrap form to cathode. Indicative discount band: $250–$450/MT below LME 3M Grade A. Tighter end of the band: multi-container parcels to nearby destinations (Mersin, Mundra). Wider end: single 20GP to distant ports (Busan, Tianjin) with full inspection package.
Berry / Candy (ISRI Berry, Candy) — discount band
Berry — clean unalloyed copper wire under 1/16 inch — discount band $350–$550/MT below LME 3M. Slightly wider than Millberry because the smaller gauge gives marginally lower density and a small recovery penalty at the refiner. Common destinations: Indian refiners, Turkish brass mills, Korean rod plants.
Birch / Cliff (ISRI Birch, Cliff) — discount band
Birch (#1 heavy copper, 96% Cu) and Cliff (#2 mixed copper, 94% Cu) trade at $500–$800/MT below LME 3M. The wider discount captures recovery loss on tinned/lacquered surfaces and the smaller buyer pool — Birch/Cliff suits secondary refiners and brass mills with the metallurgy to handle 4–6% impurity content.
Insulated copper wire — recovery-based pricing
Insulated copper wire is priced on contained copper, not gross weight: price = (LME 3M Cu × recovery %) − processing discount of $300–$600/MT. Houses Wire #1 typically contracts at 65–70% recovery; Druid #2 at 50–60%; mixed telephone wire at 40–45%. Discharge-port verification typically allows ±2% tolerance on recovery before credit/charge adjustments.
Copper cathode — premium, not discount
LME Grade A cathodes (Cu-CATH-1 99.99% Cu) trade at a PREMIUM over LME because they are physical delivery-grade metal: $80–$220/MT CIF Asia depending on brand, packaging, tonnage and destination. The premium is set by physical demand at the discharge market, not by scrap discount mechanics.
What moves the copper scrap discount
Five drivers: (1) LME absolute level — discounts widen slightly when LME spikes because buyers tighten budgets; (2) freight rates — Rotterdam-to-Asia container rates have ranged $80–250/MT over 2024–2026; (3) cathode premium in the destination market — when cathode premium is high, scrap discount narrows as buyers substitute; (4) Chinese scrap import quota policy; (5) buyer-specific factors — tonnage, payment terms, inspection complexity.
How to use this index
These bands are indicative for budgeting and comparison, not firm quotes. For a firm offer, send RFQ specifying grade, tonnage, destination, payment terms and quotation period. We respond within 24 hours with a written CIF/FOB offer locked to the LME 3M Grade A reference at offer time. Bands published here are reviewed quarterly.
Recent benchmark moves
Over the last 12 months, Millberry CIF Nhava Sheva discount has ranged $280–$410 as freight from Rotterdam to West India has oscillated with Red Sea routing decisions. Berry CIF Mersin has ranged $380–$520. Houses Wire #1 recovery-priced contracts to Busan have ranged $4,500–$5,800/MT in absolute terms, driven by LME absolute level changes from $7,800 to $9,400/MT.
Hedging your discount
Buyers can hedge LME exposure but the discount itself is illiquid. The way to lock the discount is to sign a Nautica frame contract committing to monthly tonnage at a named discount band — we then guarantee the band across the contract life subject to a force-majeure clause for freight market dislocations beyond a defined threshold.

Indices are useful for context but a firm offer is always sharper than a band. Send your RFQ — we return a written offer within 24 hours with the full LME-linked math and the exact discount your specific RFQ qualifies for.
