SHIPBUILDING AND SHIP REPAIRING 
The leading industry of Hamburg is that of shipbuilding. There 
are at present 90 shipyards and allied industries located at this port, 
covering over 500 acres and employing about 20,000 men. Of the 
total number located in the harbor, 59 are in the free port, employ- 
ing about 12,000 men under normal conditions. The building of ships 
is not permitted in the free port of Bremen, but the repairing and 
equipping of ships may be carried on within the zone. For this 
purpose there is a small floating dock and a repair shop in the free 
port. Although there are no shipbuilding or repair plants in the 
free port of Kiel, there are numerous excellent shipyards in her 
harbor. Ship-repair facilities, belonging to the North German Lloyd 
Steamship Co., are available in the free port of Bremerhaven. 
The yards are well equipped and offer their facilities to all vessels 
which need repairs while at the port. There are no shipbuilding or 
repair works in the free harbors of Flensburg, Emden, and Cuxhaven. 
Sulina does not prohibit shipbuilding, but there is none carried on 
within the port. However, there are facilities for the repair of vessels 
located within the free port. The ports of Copenhagen, Malmo, 
Leghorn, Trieste, and Fiume have no facilities for the building or 
repairing of ships within their respective free zones, but have these 
facilities in the adjacent customs ports. The facilities for shipbuild- 
ing and ship repairing at Danzig are not adjacent to the free zone, 
but are located approximately 7,000 meters up the Tote Weichsel. 
Up to the present time there have been no shipbuilding or ship repair 
plants located in the free harbor of Gothenburg. The free ports of 
Barcelona, Almeria, and Bilbao, Spain, and Saloniki, Greece, do not 
have shipbuilding or repairing facilities, and the water frontage of 
these zones is too limited to permit the establishment of such facili- 
ties. There are no shipbuilding or repairing activities in the free 
vorts of Cadiz and Santander, Spain, and Stockholm, Sweden. 
Article 115 of the United States Customs Regulations, 1923, pro- 
vides that equipment, repairs, repair parts or the materials to be 
ased or the expenses of repairs made in a foreign country upon a 
United States vessel engaged in the foreign or coasting trade, or 
intended to be so engaged, are dutiable, and consumption entry 
must be made for them at the port of first arrival in the United States. 
Vessels operated for the account of the United States Shipping 
Board are subject to the provisions of section 466 of the tariff act of 
1922, and are permitted to proceed without payment of duties and 
vouchers presented to the managing agent of the board at the port 
at which entry is made. 
It is not necessary for masters to procure consular invoices, but 
they file with the entry in lieu thereof receipts showing the cost of 
the above items. If it is impracticable to produce such receipts at
