Copper wire grades we export
Bare bright copper wire (ISRI Barley/Millberry): 99.95% Cu, smallest LME discount. Berry/Candy: clean unalloyed copper wire under 1/16 inch, slightly wider discount. Houses Wire #1 (ISRI Dream/Druid family): insulated copper cable with 65–70% copper content recovery. Druid #2: lower-recovery mixed insulated wire at 50–60% copper content. Stripped wire: cable already stripped of insulation, sold at near-Berry pricing.
Insulated copper wire — recovery economics
Insulated copper wire is priced not on gross weight but on contained copper at an agreed recovery percentage. Houses Wire #1 typically contracts at 65–70% Cu recovery; Druid #2 at 50–60%; Mixed Telephone wire at 40–45%. The contract quotes a $/MT figure equal to (LME 3M Cu × recovery % minus processing discount). Buyers running granulators in Korea, India and Turkey prefer insulated wire because their plant economics convert PVC insulation into salvage revenue.
ISRI specifications
Barley (bare bright wire 99.95% Cu, ≥1/16 inch); Berry (clean unalloyed copper wire <1/16 inch); Candy (Berry equivalent for No.1 clippings); Dream (heavy insulated copper wire, plastic insulation); Druid (No.2 insulated copper wire with mixed insulation). Every Nautica wire contract names the ISRI code in the specification clause.
Inspection process
Bare wire is XRF-tested and visually graded against ISRI master samples; insulated wire is sampled by cutting representative bundles and burning/stripping to measure actual copper recovery. Recovery test results are appended to the contract. Pre-shipment inspection by SGS, BV, Intertek or CCIC is available — the inspector witnesses container stuffing, samples insulated lots, and seals before B/L.
Packaging
Bare wire loads loose at 22–24 MT per 20GP, or in pressed bales of 250–500 kg. Insulated wire loads loose at 18–20 MT per 20GP (lower density) or in 1-ton bulk bags. Containers are floor-lined, photo-documented and sealed with high-security bolts.
Export documentation
Commercial invoice, packing list, B/L, weight tickets, EUR.1 where applicable, Annex VII for non-OECD destinations, XRF/recovery test report, and buyer-nominated inspection certificate. Indian, Chinese, Turkish and Korean buyers receive country-specific document formats.
LME-linked pricing structure
Bare wire: LME 3M Grade A copper minus $250–$450/MT discount. Insulated wire: (LME 3M Cu × agreed recovery %) minus processing discount of $300–$600/MT. The recovery percentage is locked at contract, and discharge-port verification triggers a credit/charge if recovery falls outside the contract tolerance band (typically ±2%).
Destinations
Bare wire: Nhava Sheva, Mundra, Tianjin, Shanghai, Busan, Mersin, Jebel Ali. Insulated wire: predominantly Korean and Indian granulator plants — Busan, Nhava Sheva, Chennai. Weekly direct sailings from Rotterdam on the main Asia and Middle East services.
