In the copper scrap hierarchy in India, copper mill berry and copper granules sit at the top of the secondary market grades below copper cathode. They command prices that are sometimes within five percent of LME copper spot — significantly higher than insulated wire or mixed copper scrap. Understanding why these grades are valued so highly helps both buyers and sellers make better decisions.

The short answer is preparation and consistency. Both copper mill berry and copper granules are clean, uncontaminated, easily processable forms of copper. A smelter or alloy producer who receives copper mill berry can charge it straight into a furnace with minimal sorting, stripping, or processing. That time and cost saving is what gets reflected in the price they will pay.

What Copper Mill Berry Actually Is

Copper mill berry is a specific category of clean copper scrap that comes from wire drawing and rolling mill operations. When copper rod is drawn into wire or rolled into sheet, the process generates offcuts, trimmings, and production waste. This material is clean and uncoated because the copper has never been insulated, plated, or mixed with other metals in this application.

Mill berry typically comes in the form of clean wire coils, bunched offcuts, or small sections of drawn wire — all bare and bright copper with no contamination. The name comes from the original use of the grade in metal trading: berry-sized pieces of clean copper from a mill.

Where mill berry comes from in India

• Wire drawing plants producing copper wire rod for electrical applications
• Copper sheet and strip rolling operations
• Electrical transformer winding operations that generate clean copper strip and wire offcuts
• Motor rewinding operations — though this needs careful sorting to ensure insulation is fully removed

What Copper Granules Are and How They Are Produced

Copper granules are a processed form of clean copper produced by shredding and granulating copper wire and cable after the insulation has been removed. The granulation process chops the stripped copper into small, uniform pieces — typically a few millimetres in diameter — that are easy to weigh, sample, and feed into downstream processes.

The value of copper granules lies in their standardisation. Unlike bare wire or loose offcuts, granules have a consistent particle size and a clean surface. They are easy to blend with other copper or alloy inputs, easy to analyse by sampling, and easy to process in a continuous casting or furnace operation.

How granules are made

The process starts with stripping insulated cable — mechanically stripping the insulation in a granulation line that shreds the cable and then uses air and density separation to separate the copper granules from the insulation fragments. The output is a stream of clean copper granules and a stream of plastic insulation that goes to separate recycling.

Well-produced copper granules from a modern granulation line are typically above ninety-nine percent copper purity. Poorly produced granules — from incomplete insulation separation — can carry plastic fragments or mixed metal contamination that reduces their value.

Pricing of Copper Mill Berry and Copper Granules

Both grades price at a small discount to LME copper compared to other scrap grades:

• Copper mill berry — typically priced at a discount of around five to ten percent below LME copper spot, depending on purity and the specific composition of the material
• Copper granules from well-produced granulation — similar pricing to clean mill berry when purity is confirmed above ninety-nine percent
• Copper granules with some impurity or from uncertain sources — a larger discount applies until a grade analysis is done

The price difference between mill berry and insulated wire scrap of the same gross weight can be very significant — often more than double per kg. This is why sellers who can deliver mill berry or invest in granulating their cable scrap before selling make much more money per tonne than those who sell insulated wire directly.

How to Source Copper Mill Berry and Granules in Tamil Nadu

For buyers who need copper mill berry or high-purity copper granules in Tamil Nadu, the most reliable source is a certified secondary copper smelter that operates its own granulation and sorting infrastructure. Buying from a trader who cannot show you the source and processing documentation is a risk — the grade may not be what is claimed.

Shri Sabhari Metallurgical Smelters supplies copper mill berry and copper granules from its Chennai facility. We source from verified industrial generators and process through certified equipment. Grade analysis reports accompany each lot.

Conclusion

Copper mill berry and copper granules represent the top of the secondary copper market in India. For sellers, producing or delivering material that qualifies for these grades is the most effective way to maximise the value of your copper scrap. For buyers, sourcing certified mill berry or granules from a documented supplier is the most cost-effective alternative to primary copper cathode for most manufacturing applications.

FAQs

What is copper mill berry?

Copper mill berry is a high-purity copper scrap grade generated from wire drawing and rolling operations. It is clean, uncoated, and highly valued in recycling markets.

Why do copper granules command strong prices?

Copper granules are clean, standardised, and easy to process, which reduces sorting and recovery costs for smelters and manufacturers.

How are copper granules produced?

Copper granules are produced by shredding and separating stripped copper wire and cable through granulation and density separation systems.

What affects the quality of copper granules?

Purity, contamination levels, insulation separation quality, and consistency of particle size all affect the value of copper granules.

Are copper mill berry and granules used in manufacturing?

Yes. Both grades are widely used in foundries, alloy production, and copper processing because they offer reliable secondary copper input material.
