BT2026 is shown as the consolidated 2026 value; the schedule value is shown separately.

Roman-numeral columns mapped to calendar years by matching against BT2026 consolidated 2026 rates (75 informative lines; match counts per column {5: 75, 2: 25, 3: 25, 4: 27, 6: 27}). Column (VI) = 2026. Status DERIVED – verify against Decree 115/2022/NĐ-CP.

Column A (hidden STT, formula =A(n-1)+1) contains #REF! cached errors; it is a running number only and is NOT used. Several HS codes appear on multiple rows with different conditions/rates; all rows are kept in source order.

Column G "X" = mã HS 2017 (TT 65/2017) không còn sử dụng trong biểu thuế 2023. Rows not flagged are hidden by an AutoFilter in the source; all rows are converted (hidden="1" kept). The source does NOT contain old→new code correspondence; the portal therefore shows status only.

Column G "X" = mã HS mới được bổ sung trong biểu thuế XNK 2023 (TT 31/2022). Rows not flagged are hidden by an AutoFilter in the source; all rows are converted (hidden="1" kept). The source does NOT contain old→new code correspondence; the portal therefore shows status only.

Narrative schedule (rates by goods group with dated steps). HS-level excise rates come from BT2026 column CG (TT ĐB).

HS column (10) is for reference only per the source note. 507 merged cells (hierarchy blocks) – values read from the top-left cell.

17 merged regions; tables kept cell-by-cell with column letters.

Cover sheet contains images only (drawing objects); no cell values. Recorded for completeness.
