A shipment can be finished, paid for and loaded, and still sit at port because one document was requested from the wrong office, or requested too late to be ready in time. The documents themselves are not exotic — the confusion is almost always about which office in Vietnam issues which one, and which of them the goods actually need versus which a buyer’s own customs broker will ask for anyway.
Below is what a general cargo shipment out of Vietnam needs, who issues each document, and where the customs declaration itself fits against all of it.
💬 Putting together the document set for an upcoming shipment? Tell us the goods and the destination and we will check what applies.
The core commercial documents
Three documents the exporter itself prepares, and every other document in the set exists to support or verify what these three state.
- Commercial invoice — issued by the Vietnamese exporter, stating the goods, quantity, unit price, total value, currency, Incoterm and named place, and the parties to the sale. Customs, the bank (under whichever payment method applies — see supplier payment terms from Vietnam) and the buyer all read this document first.
- Packing list — issued by the exporter, stating what is physically in each carton or pallet: quantity, weight, dimensions and marks, matched against the invoice quantity.
- Bill of lading (sea freight) or air waybill (air freight) — issued by the shipping line or its agent (sea) or the airline or its agent (air), not by the exporter. It is the transport contract and, for an ocean bill of lading, the document of title — whoever holds a negotiable original can claim the goods at destination, which is why it is the document a documentary collection or letter of credit is built around.
None of these three requires a government office. They are commercial documents the exporter and the carrier issue directly, and getting them internally consistent — the same quantity, the same names, the same Incoterm — with each other and with the purchase order is worth checking before anything is submitted to customs, since a mismatch here is what most often causes a hold later.
The customs declaration
Filed electronically through Vietnam’s customs system by the exporter or a licensed customs broker acting for it — not a paper form handed across a counter.
Vietnam’s export declaration is filed through VNACCS (the Vietnam Automated Cargo Clearance System), the electronic platform General Department of Vietnam Customs uses for both import and export declarations. In practice:
- The exporter (or, far more commonly for a company without in-house customs staff, a licensed customs broker acting on its behalf) files the declaration electronically, using a digital signature credential tied to the company.
- The declaration draws on the commercial invoice, packing list and any certificates the shipment needs, and the system assigns the shipment to a clearance channel based on its own risk assessment.
- Most shipments handled through an experienced freight forwarder or broker never require the exporter’s staff to touch the customs system directly — the broker does — but the underlying commercial documents still have to be accurate and available before the broker can file.
Whoever files it, the declaration is only as good as the commercial documents behind it, which is why the invoice and packing list above have to be right before the declaration goes in.
Certificates of origin
Which form actually leaves Vietnam depends on the destination market and the trade agreement it falls under — this is its own subject, already covered in detail elsewhere on this site.
See proof of origin from Vietnam by destination market for which certificate of origin form applies to the EU, the UK, CPTPP and RCEP routes, who issues each in Vietnam, and where a self-declaration alternative is available. Do not assume a single “certificate of origin” covers every destination — the form, the issuing office and the value thresholds differ by route.
Phytosanitary and fumigation documents
Two separate documents that are easy to confuse — one covers the goods themselves if they are of plant origin, the other covers the wooden packaging around any kind of goods.
- Phytosanitary certificate — required for plants and plant products (fresh produce, certain processed plant products, some raw agricultural materials). Issued in Vietnam by the Plant Protection Department under the Ministry of Agriculture and Rural Development, or its regional plant quarantine offices, following an inspection of the goods themselves. This document travels with the goods and certifies the shipment is free of the pests or organisms the destination market’s plant-quarantine rules are concerned with.
- ISPM 15 treatment marking for wood packaging — a separate requirement covering the wooden pallets, crates or dunnage used to pack any kind of goods, of any material, not the goods themselves. Under the International Standards for Phytosanitary Measures No. 15, wood packaging material must be heat-treated or fumigated by an accredited facility and carry the IPPC mark showing the country code, the treating facility’s registration number and the treatment code (HT for heat treatment, MB for methyl bromide fumigation). In Vietnam this treatment and marking is administered under the same Plant Protection Department framework. A shipment can need ISPM 15-marked pallets even when the cargo itself is a machine part with no plant content at all, because the requirement attaches to the packaging, not the product.
Confirm with the destination country’s own import rules which of these two — or both, or neither — actually applies; that is a question for the buyer’s side, not something Vietnamese law settles.

Who issues what — quick reference
Work down this table when assembling a document set, and check the destination country’s own requirements against it before assuming a document applies.
| Document | Who issues it in Vietnam | Applies to |
|---|---|---|
| Commercial invoice | The exporter | Every shipment |
| Packing list | The exporter | Every shipment |
| Bill of lading / air waybill | The shipping line or airline (or its agent) | Every shipment |
| Export customs declaration (VNACCS) | The exporter or a licensed customs broker, filed electronically | Every shipment |
| Certificate of origin | Ministry of Industry and Trade (Import-Export Department or provincial office) — form depends on destination route | Shipments claiming preferential tariff treatment, or where the buyer’s customs requires proof of origin regardless |
| Phytosanitary certificate | Plant Protection Department (Ministry of Agriculture and Rural Development) or its regional offices | Plants and plant products |
| ISPM 15 wood packaging treatment and mark | An accredited treatment facility, under Plant Protection Department oversight | Wooden pallets, crates and dunnage used in any shipment, regardless of cargo type |

What to put in the purchase order
Name each document individually in the purchase order, rather than writing “all necessary export documents” — a phrase that settles nothing when one turns out to be missing.
- Which documents the exporter must provide, named one by one, not bundled into a general clause.
- Who bears the cost of each certificate — some are charged per shipment, and the assumption that they are included in the unit price is exactly the kind of gap comparing Vietnamese supplier quotations covers under “documents included.”
- The deadline for each document relative to the vessel or flight departure — a certificate of origin or phytosanitary certificate obtained too late can miss the shipment even when the goods themselves are ready.
- Which party — exporter or a customs broker acting for the buyer — files the export declaration, where the Incoterm makes that ambiguous.
Frequently asked questions
1. Does every shipment out of Vietnam need a certificate of origin?
No. It is needed where the buyer wants preferential tariff treatment under a trade agreement, or where the destination customs authority requires proof of origin regardless of tariff preference. A shipment with neither requirement can move without one — see proof of origin from Vietnam by destination market for which routes actually need it.
2. Who decides whether our wooden pallets need ISPM 15 treatment?
The destination country’s own import rules, not Vietnamese law — most major markets require it, but confirm against the specific destination before assuming it applies or does not.
3. Can our factory file the customs declaration itself, or do we need a broker?
A company with its own digital signature credential and customs staff can file directly through VNACCS; in practice most exporters, especially smaller ones or first-time exporters of a given product, use a licensed customs broker to handle the filing.
4. What is the difference between a phytosanitary certificate and a certificate of origin?
A phytosanitary certificate confirms plant-health conditions were met on plant-origin goods, issued by the Plant Protection Department after an inspection. A certificate of origin confirms where the goods were made or substantially transformed, issued by the Ministry of Industry and Trade, and is about trade preference and traceability, not plant health. A shipment of plant-origin goods claiming a tariff preference can need both, for entirely different reasons.
5. Whose responsibility is it to have documents ready in time — the exporter’s or the freight forwarder’s?
Both play a role, but the underlying documents — the invoice, packing list and any certificates — can only be produced by the exporter or the relevant Vietnamese authority; a forwarder cannot generate a phytosanitary certificate on the exporter’s behalf. Naming deadlines for each document in the purchase order, as above, is what keeps the two roles from each assuming the other is handling it.
