Incoterms Guide for Vietnam Factory Sourcing:
FOB, EXW, DDP — COO & FTA Impact
The Incoterm you choose determines who controls your Certificate of Origin documentation — and therefore whether you receive your FTA tariff benefit. Here's what global buyers sourcing from Vietnam factories need to know.
What Are Incoterms — And Why Do They Matter for Factory Sourcing?
Incoterms® (International Commercial Terms, ICC 2020) are global rules that define who pays for what and who carries risk in an international trade transaction. For buyers sourcing from Vietnam factories, there are three key impacts:
Cost Allocation
Who pays inland freight to port, export clearance fees, ocean freight, insurance, and import duties? Answers vary dramatically by Incoterm.
Risk Transfer
At what point does goods damage liability shift from the factory to you? Critical for insurance planning and claims management.
COO & FTA Document Control
This is the most important: WHO manages your Certificate of Origin and FTA certificate handling at customs? This determines your tariff benefit.
Incoterms Quick Reference: Vietnam Factory Sourcing
Ranked by buyer control over import COO documentation and FTA certificate management.
| Incoterm | Factory Handles | Buyer Handles | Risk Transfer Point | Buyer Controls COO Filing? | Dewin Guidance |
|---|---|---|---|---|---|
| FOB – Free On Board | Factory gate → inland Vietnam freight → export clearance → load onto vessel | Ocean freight, marine insurance, import customs entry, COO certificate submission | Loaded onto vessel at Vietnam port | ✅ Yes — buyer's broker controls | ⭐ Recommended for most buyers |
| EXW – Ex Works | Goods available at factory gate only | Everything: export clearance, inland Vietnam, port, ocean, insurance, import customs | At factory gate | ✅ Yes — but complex Vietnam-side | ⚠️ Needs Vietnam freight partner |
| FCA – Free Carrier | Export clearance + delivery to named carrier/location | Freight from named point, insurance, import customs + COO | Handed to buyer's first carrier | ✅ Yes — buyer controls import | ✅ Good for air freight / LCL |
| CIF – Cost Insurance Freight | Export clearance + inland + ocean freight + insurance to destination port | Import customs + COO filing + inland delivery | Loaded on vessel (freight paid by seller; risk passes at vessel load) | ✅ Yes — buyer controls import entry | ⚠️ Buyer pays hidden freight markup |
| CPT – Carriage Paid To | Export clearance + all freight to named destination | Insurance + import customs + COO filing | Handed to first carrier in Vietnam | ✅ Yes — buyer controls import | ✅ Reasonable for door-to-port |
| DDP – Delivered Duty Paid | Everything including import duties + delivery to buyer premises | Nothing — all-in price | At buyer's premises | 🚨 No — factory's agent controls | 🚨 Avoid — lose FTA document control |
How Incoterms Affect Your FTA Tariff Benefit
Vietnam has 16+ Free Trade Agreements. Under each, buyers receive preferential tariff rates — but only if the correct FTA certificate of origin is submitted with the import entry. Your Incoterm determines who controls that submission.

Dolphin Audit Pillar 5: Export Compliance — Verified In Person
Every factory in Dewin's network passes our 50-point Dolphin Audit. Pillar 5 is dedicated to Export Compliance — ensuring the factory is genuinely equipped to support your COO documentation chain, regardless of which Incoterm you choose.
Pillar 5: Export Compliance — What Dewin Verifies On-Site
VCCI Registration Status
Factory must be registered with VCCI and authorized to issue Form B. Dewin physically confirms registration certificate.
Form B Issuance History
Factory must demonstrate prior Form B issuance. First-time exporters without track record require additional scrutiny.
Manufacturing Record-Keeping
Production logs, material purchase records, and sub-contractor records that substantiate Vietnamese origin must be organized and accessible.
Chinese Input Disclosure
Factory must acknowledge that Chinese-origin raw materials or sub-components require disclosure on COO documentation.
Anti-Circumvention Awareness
Factory management must understand that transshipment of Chinese goods is prohibited and what "substantial transformation" in Vietnam means.
FTA Certificate Capability
Factory must confirm capability to provide EVFTA EUR.1 / REX declarations, CPTPP self-certification, and RCEP Form CO for key markets.
QCLDM Score: How Export Compliance Affects Factory Tier
| Tier | Score Range | Pillar 5 Requirement | FOB Recommendation |
|---|---|---|---|
| Tier 1 | 85–100 | Full VCCI registration + multi-FTA CO capability + complete records | ✅ FOB — low documentation risk |
| Tier 2 | 70–84 | VCCI registered + Form B history + basic record-keeping | ✅ FOB — verify Form B process |
| Tier 3 | 55–69 | VCCI registered but limited CO track record | ⚠️ FOB with Dewin logistics support |
| Probationary | <55 | Export compliance gaps identified | 🚨 Address before accepting orders |

5 Questions to Ask Any Vietnam Factory Before Agreeing on Incoterms
Before finalizing your Incoterm and placing an order, ask your factory these questions to verify they can support your COO and FTA documentation chain.
1. Are you registered with VCCI to issue Form B certificates?
Why it matters: Required for US buyers claiming $0 Section 301 Vietnam tariff. Without VCCI Form B, your customs broker cannot correctly declare Vietnamese origin.
Red flag if "no" or "we use a third party to issue the CO" — the factory should be the direct applicant.
2. Can you show me an example VCCI Form B from a previous shipment?
Why it matters: Verifies the factory has actually done this before. A factory that's issued Form B multiple times handles it smoothly; a first-timer needs more guidance.
Yellow flag if they hesitate or say "we haven't needed it before" — first-time Form B applications can delay shipments.
3. What percentage of your raw materials / inputs are sourced domestically vs from China?
Why it matters: FTA rules of origin require specific "content value" from Vietnam or partner countries. High Chinese input % can jeopardize COO eligibility.
Red flag if > 60% of material value is Chinese-origin for most FTAs — may not meet substantial transformation rules.
4. Have you been audited for COO compliance before?
Why it matters: Factories that have been through CBP or EU customs audits understand documentation requirements. Dewin's Dolphin Audit Pillar 5 covers this.
Not necessarily a red flag if "no" — but means you need more due diligence on documentation practices.
5. Which FTA certificates can you support? (EVFTA EUR.1, CPTPP, RCEP, UKVFTA)
Why it matters: Different FTAs require different CO forms. A factory exporting to EU, UK, and Japan buyers simultaneously should be familiar with multiple CO formats.
Yellow flag if only familiar with one CO type — may need Dewin's support for multi-market buyers.
What Global Buyers Say About Sourcing with Dewin
"We've sourced from overseas before, but never had this level of transparency on the documentation side. Dewin made sure our customs broker had everything they needed — COO certificates, inspection reports, the works."
"The tariff savings are real. We were nervous about the compliance side — making sure the Vietnam COO held up — but Dewin walked our broker through the documentation on our first shipment and we haven't had an issue since."
"What sold us was the audit process and the paper trail. When we showed our customs broker the Dolphin Audit report and the VCCI Form B, they were impressed. That's the level of documentation you need to claim $0 tariffs confidently."
