Key Stats — Vietnam Tet Sourcing 2026-2027

• Vietnamese factories close 7-14 days for Tet (Chinese New Year is 5-7 days; Vietnam runs nearly 2x longer)
• Productivity drops 30-50% in the 2 weeks before Tet, takes 3-4 weeks to recover full output after
• 2026 Tet: Feb 17 (Tuesday, Year of the Horse); 2027 Tet: Feb 6 (Saturday, Year of the Sheep)
• PO cutoff rule: typical 60-day production runs require orders signed 90 days before Tet
• Post-Tet first batch defect rate: typically 2-3x normal (senior workers not returning + new-hire ramp)

Vietnam Tet Sourcing Playbook: What to Do 90 Days Before, What Breaks 30 Days After (2026-2027)

Late January to late February is the most failure-prone window in Vietnamese sourcing. The problem is not Tết Nguyên Đán (Vietnamese Lunar New Year) itself. The problem is that foreign buyers extrapolate from Chinese New Year (CNY) experience and typically underestimate Vietnamese shutdown duration by 50-100%.

This guide is the operational playbook for foreign buyers: when to place orders, when to wire payments, why the first post-Tet batch breaks, and how to handle the perfect storm when Tet and CNY collide.

1. Why Tet hits harder than buyers expect

Chinese CNY runs 7 official days, with many coastal factories closing 3-5 days early and taking 7-10 days to fully recover. Vietnamese Tet is longer on every dimension:

Dimension	China CNY	Vietnam Tet
Statutory holiday	7 days	5 days (but practical 7-14)
Worker travel home	Mid-tier city to hometown 1-2 days	South to North 3-5 days (rail + traffic)
Worker return rate	Typically 90%+	70-85%, balance switch jobs
Factory shutdown	Official 7, practical 10 days	Official 5-7, practical 10-14 days
Time to full output	1-2 weeks	3-4 weeks

Why Vietnam runs longer: large North-South economic gap means 70%+ of southern factory workers come from northern and central provinces — multi-day journeys to hometowns. Tet is the only nationwide reunion holiday in Vietnam (Mid-Autumn and National Day are nowhere close). Workers will not skip Tet to keep a job; they will switch to one that lets them go.

2. Real Tet calendar 2025-2027

Year	Tet Day 1	Vietnamese Zodiac	Typical factory shutdown window
2025	Jan 29 (Wed)	Snake	Jan 27 - Feb 9
2026	Feb 17 (Tue)	Horse	Feb 14 - Mar 1
2027	Feb 6 (Sat)	Sheep	Feb 3 - Feb 16

Special note for 2026: Tet falls on Tuesday, so many factories pull in the prior weekend (Feb 14-15) to make a 9-day stretch. Effective shutdown runs Feb 13 to Mar 1 — 16 days.

2027 Tet collides with CNY: Both fall on Feb 6, the same day. This means:

• Vietnamese factories using Chinese raw materials face simultaneous supplier shutdown
• Both supply chains stall in parallel → post-Tet steel and electronic component restocking delayed 1-2 weeks
• All-Asia spot freight rates spike in late January

3. The 90-day PO cutoff rule

Typical hardware order timeline:

• RFQ negotiation: 14 days
• Sample approval: 14 days
• Production: 30-45 days
• Export prep + sea freight: 14-21 days
• Total: ~75-90 days

Reverse calculation: to ship before Tet, the PO cutoff for 2026 Tet (Feb 17) is Nov 19, 2025. Miss that date = your order ships after Tet, arrival delayed 4-6 weeks.

Practical workflow:

• D-120 (Tet minus 4 months): start negotiation, lock supplier
• D-90: PO signed, deposit wired, production starts
• D-45: sample finalized, tooling complete
• D-30: production progress check (don't wait until D-7 to discover delays)
• D-21: start export documentation
• D-14: last safe loading window
• D-7: balance wired — this is the last vessel that can guarantee pre-Tet destination arrival

4. Payment dynamics during Tet

Vietnamese factories collect payments aggressively in the 30-45 days before Tet (Tết tháng 13: legally mandated 13th-month bonus to workers, typically equal to one month's salary).

This means:

• Factories are most cash-strapped in the 2-4 weeks before Tet
• Even if your PO is 30/70, factories may "politely" ask for early balance, or 50% deposit upfront
• Refusing risks being scheduled behind clients who paid early

Buyer strategy:

• Early payment is OK, but require written confirmation that production schedule is unchanged
• Never go to 100% prepay. Always retain 20% for third-party FRI before final payment
• Don't sign new POs for post-Tet shipping. Factories are still ramping back; new orders get pushed to D+45

5. Why post-Tet first batches break

Quality risk is highest in the 2-3 weeks of post-Tet production:

1. Workers don't all return: typical 70-85% return rate. The remaining 15-30% are new apprentices with weak technical skill
2. Senior QC turnover spikes: QC managers are most actively poached during Tet
3. Equipment recommissioning: machines stopped for 2 weeks need calibration, lubrication, test runs. Skip this and dimensional drift appears
4. Raw material backlog: upstream suppliers are also just recovering, restocking is slow
5. Catch-up mentality: factories try to make up Tet revenue by accepting overflow orders, compressing QC

Buyer response:

• Mandatory FRI on every order shipping before D+30 (even if you don't normally do FRI)
• Expect defect rates 2-3x normal; budget 5% reorder buffer in the PO
• Don't drop surprise large orders within D+15 of Tet (they get pushed to D+60 production)

6. Tet + CNY perfect storm (next occurrence: 2027)

When Tet and CNY fall in the same week (Feb 6, 2027), the entire East Asia supply chain experiences:

Effect	Duration	Impact on you
Vietnamese southern factories using Chinese steel/electronics → simultaneous restocking delay	Post-Tet 2-3 weeks	Production timeline extended
Sea freight spot rates spike 30-60%	Jan 15 - Feb 15	Logistics cost surge
Port congestion (exporters racing to ship pre-Tet)	2 weeks pre-Tet	Missed containers pushed post-Tet
Customs understaffed, clearance slows	During Tet	Add 2-3 days to clearance time
Vietnam inland logistics (rail/truck) congestion	1 week each side of Tet	Factory-to-port delays

2027 prep should start one month earlier. From early November, all orders should be signed.

7. D-90 to D+30 complete playbook

D-120  Lock supplier, start RFQ + sample workflow
D-90   PO signed, 30% deposit wired, production starts
D-60   Sample finalized, tooling complete
D-45   50% production progress check (photos + random sampling)
D-30   Production complete, start export documentation
D-21   File CO (3 business days required)
D-14   Last safe loading window
D-7    Last pre-Tet vessel sails, 70% balance wired
D-3    Factory shutdown begins (senior workers leave 3 days early)
D+0    Tet Day 1
D+5    Statutory holiday ends, but factories still empty
D+10   Workers gradually return (typical 60% on-site)
D+14   Nominal "reopening" (actual 70-80% on-site)
D+21   Equipment recalibrated, production line ramping
D+30   Full output restored
D+45   First post-Tet batch ready for normal delivery

8. 8 Tet sourcing traps

1. "No problem, we don't close for Tet" — small/mid factories are lying. Vietnamese workers will quit a factory that doesn't honor Tet
2. "We can squeeze in extra orders the week before Tet" — workers are already mentally home. Rush orders generate quality problems
3. "Post-Tet first batch we can do cheaper" — sales tactic, you eat the quality issues
4. 100% prepayment — Tet is the highest factory-disappearance-risk window of the year
5. No safety stock for Tet period — even 6-8 weeks of destination-country buffer inventory is reasonable
6. Using 2026 timing for 2027 — Tet collides with CNY in 2027, add 2-3 weeks buffer
7. Assuming "Vietnam factories work like China" — Tet shutdown runs 50-100% longer than CNY
8. Sending email during Tet expecting reply — owners and salespeople have phones off, visiting ancestral graves. Treat Feb 13-22 as full radio silence

Conclusion: Tet is the most important annual supply chain planning event

Many foreign buyers start thinking about Tet in Q4. That is too late. Tet planning belongs on Q3 meeting agendas.

The single most critical decision: the mid-November PO cutoff (90 days before Tet). Miss it, and you accept 4-6 week post-Tet shipment delays. There is no middle ground.
