General Characteristics
Zinc is the fourth most widely used metal after steel,
aluminum and copper in the world. Due to its resistance
to non-acidic atmospheric corrosion zinc is instrumental
in extending the life of buildings, vehicles, ships
and steel goods and structures of every kind.
Zinc is a bluish-white lustrous metal. It is
normally covered with a white coating on exposure
to the atmosphere. Zinc dust is flammable when
exposed to heat and burns with a bluish-green
flame. Zinc also exists in many compounds. Zinc
has a role in normal human growth, taste, and
sperm development, but exposure to high levels
of zinc through inhalation, ingestion, and dermal
contact can cause adverse health effects.
Zinc is used for alloys, electroplating, metal
spraying, electrical fuses, batteries, rubber,
paint, glue and matches. Zinc is registered as
a fungicide, herbicide, and rodenticide. The primary
stationary sources of zinc are electric services,
petroleum refining, crude petroleum and natural
gas extraction, manufacturing of fabricated rubber
products, manufacturing of fabricated metal heating
and plumbing products, and manufacturing of inorganic
chemicals. Indoor sources include infiltration
of outdoor air, smoking, cooking, and other indoor
sources. The average indoor concentration of zinc
is normally slightly higher than the outdoor level.
Zinc occurs naturally in the earth's crust.

Domestic Scenario
- The Indian zinc industry entered its transformation
phase with the privatisation of the largest
zinc producer, Hindustan Zinc Ltd, in favour
of the Sterlite group in April 2002. The domestic
zinc industry is now completely under the private
sector and is in the midst of a serious expansion
programme.
- By 2010, India is expected to attain complete
self-sufficiency in meeting its zinc demand.
Thereafter, the process of India becoming an
important zinc supplier to the world would
be initiated, provided that another phase of
capacity expansion is effected.
- The country's zinc demand, which stood at
3.5 lakh tonnes in 2003-04, is expected to
rise to 4 lakh tonnes in 2004-05, including
imports 65,000 tonnes.
- Over the next five-six years, zinc demand
is likely to grow at 12-15 per cent annually,
against the global average of 5 per cent.
- Even if one assumes that zinc demand grows
by 10 per cent till 2010 and at slower 7 per
cent thereafter, India would require zinc capacity
of 14 lakh tpa by 2020, in order to be self-reliant.
The next round of large capacity additions
would, therefore, be warranted from 2008 onwards.
- Buoyancy in domestic zinc demand primarily
emanates from the boom in the steel industry,
given that over 70 per cent of zinc is used
for galvanizing. The steel industry has bright
prospects with demand drivers being the construction
industry and exports. Other sources for demand
would be die-casting, guard rails for highways
and imported-substituted zinc alloys.
Global Scenario
Substitutes: Aluminum, steel, and plastics substitute
for galvanized sheet. Aluminum, plastics, and
magnesium are major competitors as diecasting
materials. Plastic coatings, paint, and cadmium
and aluminum alloy coatings replace zinc for
corrosion protection; aluminum alloys are used
in place of brass. Many elements are substitutes
for zinc in chemical, electronic, and pigment
uses.

Due Date Rate Computation
DDR is calculated on the last day of the contract
expiry, by taking LME cash prices of Lead in
USD, multiplied by Rupee-USD rate as declared
by the RBI on that particular day.
DDR = LME Cash Price (on the last day of contract)
x INR/USD rate of RBI
Approximate MCX Contract Parity Price in INR
on Normal Days Against LME Cash and 3M Prices
MCX USD Parity Price:
LME Cash Price + (LME 3M Price - LME Cash Price)
* Remaining days to maturity/90
MCX INR Parity Price:
MCX USD Parity Price * INR/USD forward rate
