A new product may create three separate customs questions: which HS code controls taxation and regulatory treatment; which customs valuation method and adjustments apply to the transaction; and which country or territory is the origin under the relevant rules. A forwarder’s opinion or a previous “similar” shipment may not be sufficient when technical specifications, commercial terms or production processes differ. Vietnam’s advance determination mechanism allows a declarant to request a written customs determination before clearance. This article separates the three procedures, explains their evidence requirements, processing time, validity and limitations, and shows how to integrate the result into an import–export control workflow.

Legal update: 20 July 2026 · Scope: advance classification, customs valuation and origin determinations in Vietnam.

QUICK FACTS

Three procedures answer different questions

Classification concerns the product; valuation concerns the transaction; origin concerns materials, production and the applicable origin rule.

File before customs clearance

The proposed goods or transaction must be described with enough evidence for Customs to reach a conclusion.

30 days for ordinary cases

A complex case may take 60 days from receipt of a complete file; an ineligible or deficient request may be refused within five working days.

Not an unconditional guarantee

The determination applies only when the actual goods, transaction, production process and documentation match the submitted facts.

SCOPE

This guidance applies to traders planning an export or import and seeking an official basis before lodging a customs declaration. It is particularly relevant to new or multifunctional products, sets and components, goods with unusual composition, transactions involving royalties, assists, rebates or related parties, and products manufactured across multiple countries.

It does not determine the correct HS code, value or origin for any particular product. The applicant must use the actual technical file, contract, transaction and production records. A ruling for a “similar” item cannot safely be extended where a difference may change the legal analysis.

KEY TERMS

Term	Meaning	Operational role
Advance classification determination	Customs determines the product name and code under Vietnam’s import–export nomenclature before clearance.	Supports HS declaration, tax calculation and code-based regulatory screening.
Advance customs valuation determination	Customs determines the valuation method or, where applicable, a specific value.	Clarifies valuation logic, adjustments and transaction evidence.
Advance origin determination	Customs determines expected origin based on materials, production and the applicable origin rules.	Supports policy decisions but does not replace proof of origin.
Advance ruling / advance determination	A written pre-clearance customs decision based on a defined set of facts.	Reduces uncertainty but remains limited by the submitted facts and current law.
Valuation method	The legally prescribed method used to determine customs value.	Different from a specific value applicable to one transaction or shipment.
Advance determination notice	The written result issued by the Director of the Customs Department under the current structure.	A declaration basis where the actual shipment matches the notice.

HOW THE MECHANISM WORKS

1. The applicant must establish the facts, not merely request an answer

A classification file requires composition, structure, use, operating principle and technical evidence. A valuation file requires the transaction structure, buyer–seller relationship, price terms, payments and adjustments. An origin file requires the bill of materials, HS codes and origin of inputs, cost data and production steps.

2. The determination is tied to the submitted product and conditions

At clearance Customs may compare the notice with the declaration and the physical goods. A change in model, composition, function, manufacturer, transaction terms or production process may place the shipment outside the determination.

3. Responsibility for the declaration remains with the declarant

The enterprise must still declare accurately, produce the notice where relevant and maintain supporting evidence. A change related to the requested goods must be notified in writing to the Customs Department within ten working days.

Common misconception: an origin determination is not a certificate of origin; an HS determination does not waive specialised inspection; and a valuation determination does not guarantee acceptance of later invoices if the transaction changes.

COMPARISON OF THE THREE PROCEDURES

Criterion	HS classification	Customs valuation	Origin
Core question	Which heading, subheading and national code apply?	Which method or specific value applies?	Which country or territory is the origin under the relevant rule?
Primary facts	Objective product characteristics.	Price, transaction, payments and adjustments.	Materials, production, costs and origin rule.
Core documents	Form 01/XĐTMS/NVTHQ; technical documents; sample where available; analysis or inspection certificate if requested.	Form 02/XĐTTG/NVTHQ; contract; catalogue; transaction documents; bank and transport records for a specific value where applicable.	Application under Appendix I to Circular 33/2023; cost statement; input declarations; production process; catalogue or images.
Frequent weakness	Trade description only, missing composition/function, or multiple variants grouped together.	Confusing method with price; missing royalty, assist, rebate, relationship or freight/insurance facts.	Treating shipping country or expected C/O as origin without proving the applicable rule.
Use of result	Only for goods matching the file while the legal basis remains valid.	Method may apply during the validity period; a specific-value result applies directly to the identified shipment.	Only while materials, process and origin rules remain the same.

DOCUMENTS AND DATA TO CONTROL

File	Minimum data	Source owner	Pre-filing control
HS classification	Product name, model, composition, structure, use, operating principle, drawings, photographs and sample.	Manufacturer, engineering, R&D or an authorised testing body.	One file should represent technically identical goods; marketing material is not a substitute for technical evidence.
Valuation – method	Proposed contract, Incoterms, relationship, payments, royalty, assists, discounts, freight and insurance.	Procurement, finance, tax, legal, seller and logistics providers.	Separate invoice price from customs value and identify quantifiable additions or deductions.
Valuation – specific value	Contract or equivalent, bank payment, transport document, technical file and related transaction records.	Bank, carrier/forwarder, seller and importer.	A specific value is transaction-specific and should not be reused for different terms.
Origin	BOM, HS and origin of materials, input value, production costs and steps in each country.	Manufacturer, suppliers, sourcing and compliance teams.	Select the correct non-preferential or FTA rule set and maintain traceable source evidence.
Document governance	Version, approver, effective date, assumptions, attachment index and post-filing changes.	Internal document owner.	Do not silently replace files; changes require impact assessment and timely notification.

PROCEDURE AND TIMELINE

Define the exact request: classification, valuation method, specific value or origin.
Freeze the relevant version: model, specification, manufacturer, BOM, proposed contract and Incoterms.
Collect source evidence: manufacturer documents, contracts, bank records, cost statements and production records.
Use the current form: 01/XĐTMS/NVTHQ for classification, 02/XĐTTG/NVTHQ for valuation, and the Circular 33/2023 application for origin.
Reconcile the file: names, models, units, values, manufacturers, materials and attachments must be consistent.
Submit to the Customs Department: through the channel published on the National Public Service Portal; retain the receipt and filed version.
Respond to clarification: provide dialogue, analysis, inspection or additional evidence where requested.
Track statutory processing: possible refusal within five working days; 30 days for ordinary cases or 60 days for complex cases after a complete file is received.
Integrate the result into master data: link the notice number, assumptions and source file to the SKU or transaction.
Revalidate before each shipment: confirm that product, transaction, production and law have not changed.

VALIDITY AND NON-APPLICATION EVENTS

Status	Correct interpretation	Enterprise action
Notice within its validity	Maximum validity is up to three years; a specific-value notice applies directly to the identified shipment.	Monitor issue date, scope and the legal instruments used as the basis.
Actual facts differ	The notice does not apply where the actual goods or file differ from the submitted sample or documents.	Stop relying on it, prepare a gap analysis and reapply where necessary.
Law changes	The notice ceases to apply when the underlying legal rule is amended, supplemented or replaced.	Monitor HS nomenclature, tariff, origin and valuation changes.
Inaccurate or dishonest submission	Customs may cancel the notice.	Control source evidence, internal approval and manufacturer confirmation.
Applicant disagrees	The applicant may request review; Customs responds within 10 working days or 30 days for a complex case.	State the contested point, legal basis, evidence and requested conclusion.

RISKS AND COMMON ERRORS

Error	Impact	Control
Filing shortly before arrival	No result before declaration; tax, licence and landed-cost decisions remain uncertain.	Start during sourcing, before booking and before an irreversible commitment.
Using sales literature as technical evidence	Insufficient basis to distinguish the product.	Obtain data sheets, composition, drawings, manuals and manufacturer confirmation.
Requesting one code for many variants	The notice may not cover all SKUs or the file may be rejected.	Group products by legally relevant characteristics, not brand or series.
Equating origin with shipping country	FTA and trade-policy errors.	Map the BOM and production steps and apply the correct rule set.
Omitting payments or adjustments	The proposed valuation does not reflect the transaction.	Have finance, tax, legal and procurement review royalties, assists, rebates and related parties.
Failing to control changes after issuance	An out-of-scope or expired notice is used.	Apply change control and a ten-working-day notification trigger.

LEGAL BASIS AND OFFICIAL SOURCES

Source	Role	Application note
Customs Law No. 54/2014/QH13	Article 28 establishes advance determination of classification, origin and customs value.	Read together with implementing and amending instruments.

National Public Service Portal – classification; origin; valuation	Published filing authority, submission channel, document list and processing time.	Recheck immediately before filing because forms and channels may change.

FAQ

1. Is an advance HS determination mandatory?

No. It is a request-based mechanism, useful where classification risk is material or an official basis is needed before the transaction.

2. Can one determination cover multiple shipments?

Potentially, if the actual goods and documents fully match, the notice remains valid and the underlying law has not changed. A specific-value determination applies directly to the identified shipment.

3. Can an enterprise rely on another company’s published determination?

It should be treated as reference only. The result is based on the applicant’s specific facts, evidence and goods.

4. Does an advance origin determination automatically grant FTA preference?

No. The importer must still meet the agreement conditions, declare correctly and submit the required proof of origin.

5. Can valuation guidance be requested before a final contract exists?

For an advance valuation method, the law allows a request for principles and conditions where the actual transaction documents are not yet available. A specific value requires more concrete transaction evidence.

6. Does the notice prevent Customs from inspecting the shipment?

No. Customs may verify consistency between the notice, declaration and actual goods and may redetermine where they do not match.

7. Can the result be reused after changing manufacturer?

Only after a careful impact assessment. A new manufacturer may alter composition, process, origin or technical evidence, so automatic reuse is unsafe.
