special instances, for examination by the appraisers. All packages 
entered for consumption not specified for examination may be imme- 
diately delivered to the importer upon his filing a bond covering 
double the estimated value of the merchandise for the return of any 
packages so delivered within 10 days after the examination packages 
have been appraised. Cargo must not be removed from the pier, 
however, until necessary customs weighing, gauging, etc., has been 
done. 
Delivery may be secured at dock of all free goods and of such goods 
entered for consumption as are not selected for appraisement. Pack- 
ages containing dutiable goods entered for consumption and selected 
for appraisement will be delivered to the importer after examination 
if duties paid are found to have been sufficient. Goods selected for 
examination are carted for that purpose to the appraisers’ stores, 
except that fragile or bulky articles, machinery, inflammable or 
explosive substances, and textiles requiring analysis may be appraised 
upon the wharf, or on the importer’s premises, or sent to the nearest 
port where there is a textile analyst, as the case may be. Goods 
entered for warehouse are sent to bonded warehouses, from which 
delivery may be made upon the payment of duties, storage charges, 
etc. Free goods, unless in packages containing dutiable goods, and 
also perishable goods and explosive or inflammable substances, can 
not be entered for warehouse. Goods entered for transportation 
without appraisement are delivered to bonded transportation com- 
panies. 
Bonded warehouses.—Warehouses for the appraisal and storage of 
bonded merchandise are permitted to be used only for that purpose 
and for the storage of unclaimed goods under Government control. 
They are classified as follows: 
Class 1: Premises owned or leased by the Government and used for 
the storage of merchandise undergoing examination by the appraiser, 
under seizure or pending final release from customs custody, and 
known as a “public store.” Unclaimed merchandise stored in such 
premises are held under “general order.” Where such premises are 
not sufficient or available for the storage of seized and unclaimed 
goods, such goods may be stored in a warehouse of class 3. If there 
is no warehouse of that class, the collector may, with the approval of 
the department, rent suitable premises for the storage of seized and 
unclaimed goods. 
Class 2: Importers’ private bonded warehouses used exclusively 
for the storage of merchandise belonging or consigned to the pro- 
prietor thereof. 
Class 3: Public bonded warehouses used exclusively for the 
storage of imported merchandise generally. A warehouse of this 
class must consist of an entire building, or a part of a building entirely 
separated from the rest of the building by suitable partitions or walls.
