What Millberry copper is
Millberry — globally referenced under the ISRI code 'Barley' — is the highest grade of copper wire scrap. The trade definition: bare, bright, uncoated, unalloyed, untinned copper wire, no smaller than 1/16 inch (1.59 mm) in diameter, free of burnt wire that is brittle. Chemistry runs at 99.95% Cu minimum with negligible oxidation. It is the closest scrap form to LME Grade A cathode, which is why it commands the smallest LME discount of any copper grade.
Source of our Millberry
Our Millberry stream comes from European cable manufacturers' production off-cuts, transformer winding rejects, controlled bus-bar trimmings and verified large-industrial customer arisings. We do not buy from informal collectors who routinely co-mingle tinned, lacquered or burnt wire into bright copper. This single-source discipline is why our Millberry consistently passes XRF re-checks at discharge port within 0.05% of contract.
ISRI 'Barley' specification — full text
ISRI defines Barley as: 'No. 1 Bare Bright Copper Wire. Shall consist of bare, bright, uncoated, unalloyed copper wire, not smaller than No. 16 B&S wire gauge, free from the following: burnt wire which is brittle; hair wire; wire with copper oxide present; coated wire; soldered or tinned wire.' Every Nautica Millberry contract references this clause verbatim.
Inspection at the Rotterdam yard
Inbound copper is weighed, photo-documented and visually graded against the ISRI master sample. Random handfuls are clipped to expose any internal oxidation, tinning, or lacquer that surface inspection might miss. Lots failing the visual or clip test are rejected back to the source or downgraded to Berry. Buyers may nominate SGS, Bureau Veritas, Intertek or CCIC to witness container stuffing and apply seals before B/L release.
Packaging — loose or pressed
Default is loose loaded in floor-lined 20GP containers at 22–24 MT per box. Pressed Millberry bales of 250–500 kg are available for buyers handling material via overhead crane (typical use case: Korean and Japanese rod plants). For very high-volume refiners we can supply 1-ton bulk bags on shrink-wrapped pallets.
Export documentation
Each Millberry container ships with commercial invoice, packing list, weighbridge tickets, B/L, EUR.1 origin certificate where applicable, EU Annex VII movement document for non-OECD destinations, XRF analysis report, and the buyer-nominated third-party inspection certificate. Indian buyers receive BIS-format docs; Chinese buyers receive AQSIQ/CCIC-aligned papers.
LME-linked pricing — how the Millberry discount is set
Millberry CIF prices are quoted as a discount to the LME 3-month Grade A copper settlement on the contract date. Typical Millberry discount: $250–$450/MT depending on destination freight, inspection cost and tonnage. The discount captures freight + inspection + our margin and is fixed at contract signature. Buyers see the exact LME date, premium adjustment, and resulting USD/MT figure on the quote.
Top destinations
