Prepared by LEFAMI · Reference review: 25 October 2026
For an overseas buyer, the useful question is not simply whether a supplier can send a collection of certificates. It is whether the documents describe the correct parties, material and shipment, and whether gaps can be resolved before payment or loading. This guide provides a practical review method. It does not certify LEFAMI or another supplier, and it does not decide whether a particular shipment may enter a destination country.
1. Identify the parties before reviewing the wood
Record the legal seller, invoice issuer, proposed payment beneficiary, production site and intended exporter. A trading company may use a separate processor; a manufacturer may subcontract drying or assembly. These arrangements need an explanation rather than an assumption that every name must be identical.
Ask who owns the goods at each relevant stage and who can provide the source records. If the seller is a trader, determine how its stock records connect to the processor and incoming material. If the processor is working on material owned by someone else, identify that relationship. Resolve an unexplained change of beneficiary through a verified contact before making a payment.
This is a buyer's suggested control, not a statement that every transaction legally requires the same set of company documents. Request information proportionate to the transaction, use secure channels for non-public records, and avoid circulating personal documents belonging to forest owners or workers.
2. Keep four origin questions separate
| Question | What to establish | Common shortcut to avoid |
|---|---|---|
| What is the material? | Commercial description, actual species and scientific name where needed | Assuming one trade name identifies every species in a mixed lot |
| Where was it harvested? | The actual harvest country or countries and the supporting chain | Treating the exporting country as proof of harvest country |
| Where was it processed? | Relevant processing sites and operations | Treating processing location as the complete source history |
| What is its customs origin? | The applicable origin rules and evidence for the transaction | Assuming processing in Vietnam automatically establishes preferential origin |
The supplier should explain how it established the facts it provides. If a scientific name or source country has not been verified, keep it open. Do not copy a plausible value into an import declaration merely because it appears in a previous order.
3. Build a record map for the lot
Vietnam's timber-record framework and timber-legality framework are relevant starting points. The applicable records depend on the source, species and transaction. The official Vietnamese texts linked below should be checked for the case; this English guide is not an official translation or an exhaustive statement of required documents.
A practical lot map connects the source or purchase event to the incoming stock reference, processing batch and finished packages. A buyer does not necessarily need every internal production page. It does need an agreed way to check that the source information supplied relates to the goods being purchased.
| Request to discuss | Why it helps | What still needs checking |
|---|---|---|
| Supplier's explanation of applicable timber-source records | Establishes which legal and transaction branch is being used | Whether the branch matches the actual source and seller |
| References linking incoming lots to the order | Makes the connection to the proposed shipment visible | Splits, mixed inputs and stock remaining from earlier lots |
| Processing and packing references | Connects material changes to finished goods | Subcontracted operations, replacements and package relabelling |
| Description of any claimed certification | Clarifies the exact claim being offered | Issuer, scope, validity and whether the claim covers this transaction |
An invoice, a source record and a certification claim perform different functions. One document should not be presented as proof of everything. A mark on a pallet also does not establish the full harvesting history of the products placed on it.
4. Ask the supplier to explain changes in quantity
Sawing, drying, planing and cutting can change dimensions, moisture and the measurement basis. Ask for the basis used at each stage before comparing quantities. Weight loss during drying is not automatically equivalent to a loss of wood substance. A rough-input volume and a final-product volume also need different dimensions in their calculations.
For a mixed-input order, ask how material is allocated to the shipment and how unexplained differences are investigated. A reconciliation should describe real movements, recoverable by-products and remaining stock. It should not be a manufactured balance created solely to make the paperwork look complete.
5. Review gaps before the shipment becomes urgent
Keep a short discrepancy register: the question, relevant lot or document, responsible contact, next action and agreed target date. Separate a missing document from an inconsistent document. A clear scan with the wrong lot number is a different problem from a document that has not yet been issued.
Examples worth resolving include an unverified species name, a source document covering a larger lot without an allocation explanation, or subcontractor details that do not match the processing story. Record the supplier's explanation and the buyer's decision. Do not treat an unresolved question as closed merely because it appears in an email thread.
6. Confirm destination-side obligations independently
For U.S. shipments, APHIS' Lacey Act guidance makes declaration scope depend on the product and entry conditions. The importer should establish that scope, with accurate supplier information where needed. The existence of Vietnamese export records does not answer that question by itself.
For other destinations, ask the importer or broker to identify the current timber-legality, customs and plant-health requirements separately. Keep the source and date of that advice with the transaction. Do not reuse a country checklist indefinitely without confirming that the goods and rules remain the same.
