Circular 85/2026: prepare Vietnam customs classification files before 15 September

Vietnam's Ministry of Finance issued Circular 85/2026/TT-BTC on 30 June 2026. It takes effect on 15 September 2026. The circular governs classification, analysis for classification, and the database for Vietnam's export-import goods nomenclature.

The dates must be kept separate: the instrument has been issued but is not yet effective on 18 August. Importers, exporters, customs brokers and freight teams therefore have a short preparation window before declarations begin to fall under the new circular.

Why HS evidence affects a freight booking

Circular 85 keeps the core rule that one item has one code in Vietnam's export-import nomenclature. Classification results are then used to apply the trade-control policy and tax schedule in force when the customs declaration is registered. If Customs lacks enough grounds to confirm the declarant's classification, the goods may be analysed or sent for inspection or testing.

That makes the commercial description alone insufficient. Before cargo release, the file should align the proposed eight-digit Vietnam HS code with composition, physical and chemical properties, function, production process and technical literature. The declarant may use a qualified inspection service or the official nomenclature database, but remains responsible for the accuracy and legality of submitted documents.

Special preparation for machinery shipped in parts

Articles 7-9 address combined machines, machine combinations and unassembled or disassembled machinery in Chapters 84, 85 and 90. Where equipment comes from one or more suppliers, in several consignments, and possibly through different customs offices, the declarant may choose classification by individual machine or under the applicable legal notes for the complete combination.

When using the registered-list route, the dossier includes the machinery/equipment list and a deduction-monitoring sheet in the prescribed forms. It must be filed before registering the first import declaration, electronically where the system supports it. For a compliant file, Customs confirms the list and monitoring sheet within no more than three working days. Amendments must be filed before the first declaration or before the next affected declaration.

For project cargo, this means the HS position, supplier split, shipment sequence, customs office and bill-of-materials logic should be settled before the first lot sails, not reconstructed after later lots arrive.

What happens if Customs requires analysis

The declarant must present the goods for sampling. Samples must come from the shipment, be representative, sufficient for inspection or a complaint, separately sealed and documented. The standard quantity is two samples. If the declarant imports only one sample, sampling is not performed under this provision.

Samples are generally retained for 120 days from the analysis/classification or technical-evaluation notice, subject to exceptions for dangerous, deteriorated or non-storable goods. If the declarant disputes the result or files a related complaint within that period, the sample is kept until the complaint decision.

After Customs receives a complete dossier and sample, the analysis/classification notice is issued within no more than five working days, or 20 working days where the technical process or a complex sample requires more time. If external inspection or testing is used, the notice is issued within five working days, or eight for a complex sample, after Customs receives that external result. These are notice-issuance periods under the circular, not guaranteed total clearance times.

Transition and replacement

Circular 85 replaces Circular 14/2015/TT-BTC and Circular 17/2021/TT-BTC from 15 September. Goods under a declaration already sampled before that date but without a result continue under the law effective when the declaration was registered. Machinery lists registered before effectiveness continue under Circular 14/2015 until the listed goods are fully imported.

Five checks before confirming transport

• Lock the product description to technical specifications, composition, use and production process.
• Record the proposed eight-digit Vietnam HS code and the policy and tax consequences tied to it.
• For machinery in multiple lots, reconcile suppliers, shipment sequence, customs locations, parts list and the chosen classification route before the first declaration.
• Prepare for two sealed representative samples and keep chain-of-custody contacts available if analysis is requested.
• Separate statutory analysis-notice periods from vessel cut-offs, port free time, storage, detention and the actual clearance plan.

The concrete freight impact is document readiness and sequencing. A weak technical file or an inconsistent multi-lot machinery list can turn an HS question into extra sampling, storage or rescheduling exposure. The circular does not announce a carrier surcharge, universal delay or automatic inspection of every shipment.

Confidence is high for the instrument, dates, scope, forms, sample rules, time limits and transition clauses because they were checked against the signed official text. Confidence is medium for any shipment-specific code or clearance outcome until Vietnam Customs or a qualified Vietnamese customs adviser reviews the actual goods and dossier.
