2025: as reported by partner countries

Vietnam has not filed 2025 yet, so this is rebuilt from what its 16 largest trading partners reported about trade with Vietnam (85% of Vietnam's trade). Not the same measure as the figures above — compare it only with the 2023 row beside it.

Flow20232025Change
Exports7 mn USD13 mn USD+91%
Imports199,745 USD113,641 USD-43%
  • Exports 2023: partners reported 7 mn USD where Vietnam reported 13 mn USD — 0.49× on this measure.
  • Imports 2023: partners reported 199,745 USD where Vietnam reported 138,960 USD — 1.44× on this measure.

The gap is not a rounding difference: goods re-exported through Hong Kong or Singapore, a different heading chosen by the importing customs, and origin-based versus destination-based attribution all pull the two measures apart. Use the year-on-year change, not the level.

Corresponding US tariff lines

Six digits are identical worldwide under the HS Convention, so 3103.90 is the same subheading in both schedules. What differs is how each country splits it: below are the 1 US line under 3103.90.

These are added to the General duty above, not in place of it. Whether a given article falls inside their scope — and the exclusion lists — is set out in the U.S. notes to Chapter 99, which are prose and not machine-readable, so this site does not assign them per code.

Corresponding Japanese tariff lines

3103.90 is the same subheading in both schedules (six digits are identical worldwide under the HS Convention). Vietnamese goods can enter Japan under four parallel preference routes — the columns below — and the exporter picks whichever C/O gives the better rate.
