The following are the rates of duty levied on imports of electrical 
equipment into the Netherland East Indies: 
Cables (telegraph and telephone), 12 per cent ad valorem. 
Copper (copper and brass wire for electrical conducting), 6 per cent ad 
valorem. 
Factory and steam-plant equipment, 6 per cent ad valorem. 
Machinery, 6 per cent ad valorem. 
In addition to these tariffs there is a statistical duty, which is 
levied irrespective of the countries of origin, in the form of a stamp 
tax, which requires stamps to the value of 5 Dutch cents (approxi- 
mately $0.02 in U. S. currency) on each 20 florins (approximately, 
$8) or part thereof, calculated on the aggregate value, expressed in 
full florins, of the goods included in the entry. 
POWER PRODUCTION AND RESOURCES 
An indication of the increasing demand for electrical energy in the 
Netherland East Indies by private industries and by Government 
and public-utility companies 1s shown in the increase in the installed 
capacity of the central power plants at the end of 1929 as compared 
with 1924. The increase during these years is over 60 per cent. In 
1924 the official estimate of the total installed capacity of the princi- 
pal power stations was 139,300 kilowatts, while at the end of 1929, 
new plants and extensions to the existing plants had brought the 
total up to over 225,000 kilowatts. 
Fortunately, the increased demand for electrical energy presents 
no problem to the Netherland East Indies as regards fuel supply. 
The islands, particularly in the Outer Possessions, are rich in natural 
resources, and coal and oil production is more than sufficient to take 
care of local needs ,while the water-power resources are just beginning 
to be utilized. In east Java, the center of the sugar industry, which 
is probably the most important private industry making use of elec- 
trical energy, the majority of sugar centrals use bagasse for fuel. 
At the present time approximately 65 per cent of the electrical 
energy supplied by the principal central power stations is generated 
in steam or oil plants, while the remainder is developed in water- 
power plants.
