Definition
A bill of sight is a provisional customs entry document submitted by an importer who lacks sufficient knowledge of the exact quantity or quality of incoming goods to make a complete and accurate formal entry. Rather than delay the landing of cargo, the importer submits a written description of the goods to the best of their knowledge and belief. Customs authorities then permit the goods to be landed and inspected, after which the importer is required to "perfect" the entry — that is, to file a complete and accurate declaration once the true nature and quantity of the goods has been verified.
The bill of sight operates as a temporary placeholder that enables commerce to proceed without requiring the importer to vouch for facts not yet within their knowledge.
Common Language
Modern common usage (Wiktionary): "A form of entry at the customhouse, by which goods, respecting which the importer is not possessed of full information, may be provisionally landed for examination."
Historical common usage (Webster's 1913): No distinct entry recorded.
The Wiktionary definition captures the procedural function accurately, but a researcher should note that "bill of sight" as a legal instrument carried specific statutory standing and procedural obligations — the importer was not simply filing an approximation but was bound by law to perfect the entry within a defined period after inspection. The common description omits this mandatory completion requirement, which was central to the instrument's legal character.
Common Confusion
Bill of sight vs. bill of entry: A bill of entry is the standard, complete customs declaration filed by an importer upon arrival of goods. A bill of sight is the provisional substitute filed when the importer cannot yet make a complete declaration. The bill of sight precedes and is eventually replaced by a proper entry; the bill of entry is the proper entry itself. Historical sources occasionally use the terms loosely, and researchers should confirm which instrument is being described by examining the procedural context.
Bill of sight vs. bill of lading: A bill of lading is the shipping document issued by the carrier acknowledging receipt of goods for transport — a document of title and contract of carriage. A bill of sight is a customs entry document filed by the importer with government authorities. They serve entirely different functions and involve different parties, though both may appear in the same transaction record.
Why It Matters in Research
This is an effectively obsolete term in modern customs law. Researchers encountering it in primary sources should understand that it belongs almost entirely to the era of British customs administration and its American colonial and early federal analogues. It will appear most frequently in eighteenth- and nineteenth-century commercial law materials, shipping records, and British parliamentary statutes — particularly in the context of the English customs and excise framework that predated modern tariff schedules and harmonized entry systems.
Modern U.S. customs practice under the Customs Modernization Act and the current Harmonized Tariff Schedule has replaced provisional entry mechanisms with electronic entry procedures that serve a similar function but under entirely different terminology and regulatory architecture. A researcher who finds a "bill of sight" reference in a modern document should treat it as either a historical quotation, an anachronism, or a term borrowed loosely from older sources.
The key research trap is conflating the bill of sight with other customs documents — particularly the bill of lading and the bill of entry. These are distinct instruments with distinct legal functions, and historical sources sometimes reference all three in close proximity when describing the movement of goods through a port. See COMMON CONFUSION below and the encyclopedia entry on Bills of Lading for further guidance on distinguishing these instruments.
For corpus researchers working in admiralty, shipping, or commercial law collections, the bill of sight will appear in British statutory materials (including predecessor statutes to the Customs Consolidation Act 1853), American colonial port records, and early federal customs administration documents. It is not a live instrument in modern regulatory filings.
Historical Dictionary Support
Black's Law Dictionary and Bouvier's Law Dictionary are in close agreement on the core definition: both identify the bill of sight as a provisional customs entry submitted when the importer cannot accurately describe the goods consigned to them. Bouvier adds the useful clarification that the instrument was specifically authorized by English statute for situations where the merchant is ignorant of the real quantity and quality of goods consigned to him — emphasizing that the procedure was not simply a convenience but a statutorily recognized exception to the standard entry requirement.
Neither historical source identifies the specific English statute, nor do they address the procedural consequences of failing to perfect the entry after inspection — a significant omission, since that obligation was the mechanism that gave the bill of sight its legal force rather than leaving it as a mere informal approximation. Researchers should not assume that the historical dictionary entries capture the full procedural framework; they present the concept accurately but incompletely.
Both sources reflect the instrument as it existed in the British and early American commercial law tradition. Neither addresses any American statutory equivalent in the federal customs statutes of the nineteenth century, though analogous provisional entry procedures existed under early U.S. tariff legislation.
