Total imports

Summary of Foreign Trade, Quarterly, 2018-2021 · page 423 · National Bureau of Statistics

MERGED DATASET (pagination convention): Table 332 (pdf page 423) carries 2018-2019 and Table 333 (pdf page 424) carries 2020-2021 over an identical 12-indicator x 4-quarter row set. Per-observation provenance in dimensions._source_table / ._source_page; raw_rows staged verbatim per printed row, unmerged. LABEL NORMALISED on founder instruction: T332 prints "Non Oils Exports" and T333 prints "Non-Oils Exports" - the same measure, NBS hyphenation drift. Left as printed it would split into two fragmentary series (2018-2019 and 2020-2021), the exact fragmentation the merge convention exists to prevent. Normalised to "Non-Oils Exports"; the printed form is retained on every affected observation as dimensions._source_label. Mixed units: values NGN million, shares PCT at series level. MIXED UNITS: dataset.unit_id is deliberately NULL because this table publishes both NGN-million values and percentage shares. The authoritative unit is on each series (NGN_M id 3 or PCT id 15). Set 2026-07-28 after QA noted a single dataset unit was false for 257 of 564 observations in this batch.

SPINE TABLE for annual total imports and total exports under the spine rule (founder decision 2026-07-28): where several chapter-16 tables publish the same measure, the most authoritative/precise one owns the series and the others contribute only periods it lacks. Total imports is printed in five tables - here, T336 Total, T344 Total, T348 Total Imports (all byte-identical) and T355 Imports (rounded to 1dp, 13,165,127.40 vs .35). This table wins on precision. Total exports is printed here and in T350 Exports, byte-identical. Mixed units: value measures are NGN million and share measures are percentages; the authoritative unit is on each series. MIXED UNITS: dataset.unit_id is deliberately NULL because this table publishes both NGN-million values and percentage shares. The authoritative unit is on each series (NGN_M id 3 or PCT id 15). Set 2026-07-28 after QA noted a single dataset unit was false for 257 of 564 observations in this batch. CORRECTION 2026-07-28 (QA): of the 32 cells not carried into observations, 20 are the spine-rule suppressions recorded above and 12 are the quarterly-union deduplication. An earlier note attributed all 32 to the spine rule. Arithmetic unchanged: 596 source cells - 20 - 12 = 564 observations.

Publisher: National Bureau of Statistics. Originator/compiler: the printed Source caption names many bodies (Nigeria Customs Service through NICIS, NNPCL, NMDPRA, NLNG, CBN and others); a single source_provider_id cannot express that, so it is left unresolved with the caption verbatim rather than defaulted to NBS. This ingest is observation-grained: the extractor emitted one row per observation with a cell-level source_ref and no printed-row capture, so row_count counts staged observations, not printed rows, and no raw_rows are staged.
