Vietnam’s customs framework for manufacturing investors operates on a structural split that most investors do not fully understand before site selection: the Export Processing Enterprise (EPE) model and the standard customs model have fundamentally different cost structures, documentary obligations, and supply chain implications. Choosing the wrong model — or failing to obtain EPE designation despite export orientation — is a tax and cost error that is difficult to unwind after production begins. The EPE model eliminates import duty and VAT on all production inputs; the standard model requires duty payment, VAT offset tracking, and export refund processing. For high-volume manufacturing, the difference is material.

This article is Section VIII of the 100 FAQ about Factory Setup Vietnam series. It covers questions Q71–Q80.

What is an Export Processing Enterprise (EPE) and how does it differ from a standard factory?

An Export Processing Enterprise (EPE — Doanh nghiệp chế xuất) is a foreign-invested manufacturing company operating entirely within a customs-controlled boundary (EPE zone or a fenced EPE facility) and selling 100% of production to overseas buyers or other EPEs. The fundamental customs difference: EPEs are exempt from import duty and VAT on all production inputs (raw materials, components, machinery, packaging) — inputs are treated as already “exported” from Vietnam’s domestic customs territory when they enter the EPE boundary. Standard factories pay import duty and VAT on inputs and recover via domestic VAT offset or export refund procedures. For high-volume export manufacturers, EPE status is a material cost advantage that should be evaluated at the project feasibility stage.

What are the eligibility requirements for EPE designation?

EPE designation is granted by the Industrial Park Management Authority (IPA) under Decree 35/2022/ND-CP. Eligibility requirements: (1) 100% export commitment — the company must sell all output outside Vietnam’s customs territory (overseas or to other EPEs); (2) Location within an industrial park or economic zone with a defined EPE zone, OR establishment of a separate fenced customs boundary with customs surveillance for a stand-alone EPE facility; (3) IRC must specify EPE status as a project condition. Companies cannot retroactively convert standard factory status to EPE status after operations commence without a full project amendment. Domestic sales are not permitted for EPEs — if market conditions require domestic sales later, EPE status must be terminated with resulting import duty recalculation on remaining inventory.

What import duty exemptions are available for non-EPE manufacturing companies?

For standard (non-EPE) foreign-invested manufacturers, import duty exemptions under Decree 134/2016/ND-CP include: (1) Fixed assets for production — machinery, equipment and transport vehicles forming part of the manufacturing line are exempt from import duty (not from VAT); (2) Raw materials, supplies and components imported for export production — exempt from import duty but subject to VAT; (3) Materials for manufacturing priority-sector products — expanded exemptions for high-tech, IT, and environmental-sector manufacturing. To claim exemption: goods must match the approved investment project scope; an import duty exemption list must be filed with the customs authority before importation; and manufacturing records (inventory control) must demonstrate the goods were used for the declared purpose.

How does the EPE customs boundary work in practice?

The EPE customs boundary defines the legal border between the domestic economy and the EPE’s customs territory. In practice: (1) All goods crossing the EPE boundary (inbound raw materials, outbound finished products, transfer between EPEs) must be accompanied by an electronic customs declaration filed with the customs authority; (2) Physical inspections at the EPE boundary gate are triggered by risk-scoring algorithms — low-risk shipments are cleared electronically without inspection; (3) EPE factories must maintain a customs book-keeping system (sổ sách theo dõi) recording all materials in and finished goods out, reconciled quarterly with the customs authority; (4) Internal materials movement between EPE and non-EPE entities within the same industrial park requires a full domestic import/export declaration as if crossing an international border.

How are import tariff rates determined for production inputs in Vietnam?

Import tariff rates are determined by HS code classification under Vietnam’s Preferential Import Tariff schedule (Decree 26/2023/ND-CP and annual updates). Classification requires: identification of the product’s 6-digit HS code under the Harmonized System (consistent with WTO members), then further classification to the 8-digit Vietnamese subheading. FTA preferential rates (lower than MFN rates) apply when: (1) the goods originate from an FTA partner country (EVFTA, RCEP, CPTPP, ASEAN FTAs); (2) a valid Certificate of Origin is presented at customs entry; and (3) the goods meet the relevant Rules of Origin. Misclassification of HS codes is a top customs audit finding — verify classification with a licensed customs broker before the first importation.

How does Vietnam’s participation in FTAs affect manufacturing import costs?

Vietnam is party to 17 FTAs as of 2025, including EVFTA (EU–Vietnam), RCEP (15 Asia-Pacific countries), CPTPP (11 countries including Japan, Canada, Australia), and ASEAN FTAs. For manufacturing companies: machinery and components from EU suppliers benefit from EVFTA preferential duty rates (most capital goods: 0% within 3–7 years of the agreement); inputs from Japan, South Korea, Australia benefit from RCEP/ASEAN FTA rates. The key compliance requirement is a valid Certificate of Origin (Form EUR.1 for EVFTA; Form RCEP or back-to-back CO for RCEP) issued by the relevant authority in the exporting country. Failure to present a valid CO means MFN (higher) rates apply.

What customs audit risks should a foreign-invested factory anticipate?

Vietnam Customs (General Department of Vietnam Customs) conducts post-clearance audits (kiểm tra sau thông quan) up to 5 years after importation. Top audit triggers: (1) Repeated HS code classification queries — pattern suggests deliberate misclassification; (2) High-value duty exemption claims without matching production records; (3) EPE quarterly reconciliation discrepancies (materials in vs. finished goods out vs. waste/scrap); (4) Significant changes in import volume without corresponding export growth; (5) Transfer pricing anomalies on related-party goods transactions. Customs audit findings can result in: back-payment of duties + interest (0.03%/day); administrative fines (1–3× the evaded duty); and in serious cases, criminal referral. Annual internal customs compliance reviews are the most effective mitigation.

What is bonded warehousing and when should a Vietnam factory use it?

A bonded warehouse (kho ngoại quan) is a customs-supervised storage facility where imported goods can be held in customs limbo — inside Vietnam physically but outside the domestic customs territory — without paying import duty or VAT until the goods are formally cleared into the domestic market. Key use cases for foreign-invested factories: (1) Machinery arriving before the company’s ERC and customs registration are complete (avoids port demurrage while avoiding duty obligation); (2) Goods arriving ahead of production schedule that will be cleared in batches to match production requirements; (3) Transit goods passing through Vietnam to a third country; (4) Goods held pending customer confirmation of specifications. Bonded warehousing incurs storage costs and a second customs clearance event — worth it to avoid demurrage or premature duty payment.

What documentation is required for export of finished goods from a Vietnam factory?

Export documentation requirements: (1) Electronic customs export declaration via VNACCS system; (2) Commercial invoice; (3) Packing list; (4) Certificate of Origin — for FTA preferential tariff claims by the buyer (Form B for MFN, Form D for ASEAN/ATIGA, EUR.1 for EVFTA, RCEP CO for RCEP); (5) Bill of Lading or Air Waybill; (6) Letter of Credit documents where applicable; (7) Inspection certificates where required by the importing country (e.g., phytosanitary for organic materials, REACH compliance for EU chemical-content products); (8) For EPE companies: EPE export declaration crossing the EPE boundary before the port export declaration. CO applications for EVFTA and RCEP must be filed with VCCI or the Ministry of Industry and Trade (MOIT) before shipment.

What are the most common customs compliance failures in foreign-invested manufacturing?

Top 7 customs compliance failures: (1) HS code misclassification — applying a lower-rate subheading to inputs or finished goods; (2) Duty exemption list non-filing — claiming exemption on machinery without the pre-filed list; (3) EPE quarterly reconciliation gaps — scrap/waste disposal not documented against customs records; (4) CO form errors — wrong form type for the destination country’s applicable FTA, or CO issued after shipment date; (5) Importing goods outside the approved investment scope — customs will query duty exemption for items not in the approved HS code list; (6) Non-EPE factory treating domestic raw material purchases as exempt from VAT/duty; (7) Failure to maintain customs import/export ledgers (bảng kê nhập xuất tồn) — required for all manufacturers claiming duty exemption on inputs.
