Freshness
Update frequency is tracked by source. The latest shipment or customs date can lag the delivery date and is confirmed in a sample.

Trade Data Quality & Coverage Notes
Trade-data quality depends on the underlying customs, shipment or mirror source. BillOfLadingData.com validates and normalizes available records, but does not claim uniform fields or accuracy across every market.
Coverage snapshot: Methodology
Quality dimensions
Quality is measured at source level.
The catalog and sample should be read together: one explains coverage, while the other confirms the exact records and fields for a purchase or integration.
Completeness
Completeness is assessed against fields reported by the source, not an assumption that every market publishes identical data.
Normalization
Countries, companies, products, ports, units and dates are standardized while source-native values can be retained where required.
Validation
Processing checks structure, field types, identifiers, ranges and duplicate patterns before data is added to delivery systems.
Country differences
Product language, HS-code depth, values, quantities, party names and transport fields vary by country and time period.
Suppression and confidentiality
Official sources may suppress, aggregate or omit confidential records. These limitations cannot be reconstructed from fields that were not reported.
Direct versus mirror
Granularity must be explicit.
Direct / transaction-level sources
These sources can contain record-level companies, products, dates, values, quantities, ports or bill-of-lading details. Exact attributes remain country-specific.
Mirror / bilateral sources
These sources describe flows between reporting countries and support market analysis. They may not identify shipment parties or provide bill-level detail.
