Heated Apparel Q4 2026 Compliance, Safety & Sourcing Playbook: Vietnam OEM Closure Deliverable (Cycle 7 Closure)

**Audience**: B2B private-label buyers, OEM procurement leads, supplier-side compliance officers, retail-channel Q4 launch managers.

Scope: This is the cycle-7 closure deliverable. It consolidates the nine prior cycle-7 deep-dives — compliance & certification, customs documentation & HS classification, product testing, IP protection, product safety testing, and sustainable sourcing — into one operationally usable Q4 2026 playbook for Vietnam-OEM heated apparel programs. The objective is to give a buyer or supplier team a single reference document that answers the question “What binder do I take into a Q4 2026 program review?” — without forcing them to assemble it themselves from ten separate guides.

1. Why a single closure playbook matters for Q4 2026

By 10 October 2026, a Vietnam OEM heated apparel program review has to answer ten different “show me the binder” requests from retail buyers, Amazon FBA inbound teams, US Customs & Border Protection officers, EU notified bodies, and brand-protection counsel. The documents that satisfy those requests overlap by 60-70% — the same UN 38.3 test summary, the same REACH SVHC declaration, the same Section 301 substantial-transformation binder — but each stakeholder wants them in a different order, with a different cover page, and with a different language. A fragmented set of nine PILLAR articles forces the buyer’s Q4 program manager to manually re-bundle every review.

This playbook reorganises the same 28-31 source documents into a single 9-tab closure binder keyed to the buyer’s actual Q4 calendar. It also bakes in the lessons learned from the nine prior PILLARs in this cycle: which documents Amazon FBA hazmat actually checks (the 5-doc pre-flight, not the full binder), which Section 301 substantial-transformation evidence CBP accepts (the BTN Form B plus yarn-forward BOM trace, not just a generic COO), and which REACH SVHC test cycles a Vietnam OEM can complete in 30-45 days versus 90 days. The result is a binder that does not just exist — it clears Q4 reviews.

2. The 9-tab Q4 2026 Vietnam OEM closure binder (overview)

The binder is organised into nine tabs that mirror how a Q4 review committee actually reads the package. The order is not alphabetical; it is sequenced for causal dependency — every later tab relies on at least one document in an earlier tab.

Tab	Document family	Stakeholder primary	Cycle-7 source PILLAR
—	—	—	—
T1	REACH SVHC + CPSIA + CA Prop 65 + UK REACH compliance	Buyer compliance team	10/1 P#88
T2	HS classification + Section 301 substantial transformation	US CBP / buyer customs	10/2 P#89
T3	UN 38.3 + IEC 62133-2 + UL 2054 battery pack test summary	Amazon FBA hazmat / EU NB	10/9 P#91
T4	IP protection NNN agreement + USPTO Class 009/011/025 + tooling ownership	Brand-protection counsel	10/8 P#90
T5	7-test product safety binder (drop, thermal, IP67, CPSIA, REACH, OEKO-TEX)	Buyer QA team	10/9 P#91
T6	GRS-RCS rPET chain of custody + ATIGA eco-procurement	EU sustainability team	10/10 P#92
T7	Supplier financing binder (L/C, milestone billing, supplier credit insurance)	Buyer’s CFO / supplier’s finance	10/10 P#92 + cycle-5 carry
T8	Q4 60-day hero-SKU launch calendar back-planner	Buyer’s launch manager	10/1 P#88 + cycle-6
T9	Post-launch RMA reserve + 6-metric after-sales scorecard	Buyer’s after-sales lead	10/10 P#92 + cycle-5 carry

Total binder weight: 28-31 source documents for a 5,000-unit PO; 41-46 for a 20,000-unit PO with the dual-source Cambodia backup. Per-5,000-unit PO compliance reserve sits at $0.42/unit FOB Vietnam (per the 10/1 P#88 estimate), and the OEM-side engineering reserve is $0.10/unit (10/1 P#91). Total reserves before freight: $0.52/unit, which lands as 1.4-1.8% of the FOB unit price — a known and budgetable line item.

3. Tab T1 — REACH SVHC + CPSIA + CA Prop 65 + UK REACH compliance

T1 is the first tab because every downstream tab (T3-T6) references at least one T1 artifact. The Vietnam OEM publishes four core documents in T1:

Document	Issuing body	Validity window	Lead time to obtain
—	—	—	—
REACH SVHC declaration (≤ 0.1% w/w per Annex XVII)	OEM compliance team	12 months	30-45 days for full test, 7 days for re-test
CPSIA certificate (lead + phthalates, 16 CFR 1303)	Intertek / SGS / TÜV	24 months	21-30 days
CA Prop 65 short-form warning label	OEM legal counsel	Indefinite (refresh on substance list update)	7 days
UK REACH SVHC (separate from EU REACH post-Brexit)	OEM compliance team	12 months	30-45 days

The combined T1 review window is 45-60 days if REACH SVHC and UK REACH are commissioned in parallel. The Vietnam OEM’s actual re-test cycle (when only the SVHC candidate list updates) is 7-10 days. The gap between the 45-60 day first-pass cycle and the 7-10 day refresh cycle is where most Q4 buyers miss the cut-off — they assume the binder is 60 days out when in reality the OEM can ship in 10 days once the cycle has stabilised.

B2B Soft Plant — OEM compliance reserve build**: A 5,000-unit PO at $28.40 FOB Vietnam generates $1,071 in T1 testing reserve (T1 cost = $0.21/unit per the 10/1 P#88 estimate, including 1 REACH SVHC re-test + 1 CPSIA + 1 CA Prop 65 + 1 UK REACH). This sits in a separate Vietnam-entity reserve account, not in the OEM’s working capital line, and is reconciled at the close of each PO. The buyer’s landed-cost calculator should add $0.21/unit to the FOB line as a “T1 compliance reserve” rather than rolling it into the contingency.

4. Tab T2 — HS classification + Section 301 substantial transformation

T2 is the customs tab. A Vietnam-OEM heated apparel shipment to the United States requires two layers of documentation: the HS classification itself and the evidence that the substantial transformation occurred in Vietnam (the legal threshold for claiming Vietnam as country of origin and avoiding the Section 301 25% China-origin tariff).

Document	Issuing body	Required for
—	—	—
HS classification (6101/6102/6110 garment HTS)	OEM customs broker	US CBP entry
BTN Form B (ASEAN originating goods)	Vietnam customs + VCCI	ATIGA duty-free entry to US
Section 301 substantial transformation binder	OEM compliance team + buyer	US CBP entry (if CBP challenges Vietnam origin)
VCCI C/O (Certificate of Origin)	VCCI (Vietnam Chamber of Commerce and Industry)	All ASEAN FTA claims
CBP ACE entry summary	US customs broker	Inbound clearance

The Vietnam OEM maintains the substantial transformation binder as a live document, refreshed every 6 months or whenever the BOM changes by > 5% (yarn-forward trace required). The binder contains: (a) yarn-forward BOM trace from filament to finished garment, (b) cut-and-sew operation log with timestamps and operator IDs, (c) graphene lamination NNN Tier-3 disclosure (per 10/8 P#90 IP protection tab), (d) battery pack sub-assembly evidence showing Vietnam-cell-final-assembly, and (e) a CFO-attested value-add calculation proving > 35% Vietnam value content.

B2B Soft Plant — Section 301 cost avoidance**: A 5,000-unit PO of men’s heated jackets at $28.40 FOB Vietnam, if classified as China-origin, would attract 25% Section 301 + 0% MFN = $35,500 in additional duty. Substantial transformation binder in hand saves the entire $35,500 for a 5,000-unit PO, equivalent to $7.10/unit savings. Per the 10/2 P#89 deliverable, this is the largest single savings lever in the entire Q4 2026 closure binder — larger than ATIGA, larger than GRS-RCS eco-savings.

5. Tab T3 — UN 38.3 + IEC 62133-2 + UL 2054 battery pack test summary

T3 is the lithium battery compliance tab and is the single most checked tab by Amazon FBA hazmat inbound. Amazon’s UN3481 pre-flight requires 5 documents — not 28. The 5 are:

1. UN 38.3.3 test summary (T1, T2, T3, T4, T5, T7, T8 — altitude simulation, thermal cycle, vibration, shock, external short circuit)

1. MSDS (Material Safety Data Sheet) for the cell

1. SoC ≤ 30% discharge evidence at the time of air freight tender

1. DGD (Dangerous Goods Declaration) for IATA air freight, signed by a trained shipper

1. P903 packing instruction compliance (battery alone or battery packed with equipment)

The Vietnam OEM’s UN 38.3 test summary is valid for 24 months if the cell chemistry and form factor are unchanged. For Q4 2026, the relevant test summary was issued in Q1 2026 for the 21700 cells in use, so the validity carries through Q1 2028 — no re-test required for Q4. However, if the buyer switches to a different cell vendor (per 10/10 P#92 sustainable sourcing), the entire UN 38.3 cycle restarts at $8,500-$12,000/test series and 60-90 days.

IEC 62133-2:2017 + AMD1:2021 is the EU-side equivalent and is valid for 36 months. UL 2054 (US) and UL 1642 (cell-level) are 24-month documents. The combined T3 validity for a Vietnam OEM heated apparel PO shipping Q4 2026 is: UN 38.3 valid through Q1 2028, IEC 62133-2 valid through Q1 2029, UL 2054 valid through Q1 2028 — so the battery compliance posture for Q4 2026 is stable.

B2B Soft Plant — Battery compliance reserve**: The 5-doc FBA pre-flight does not require re-testing — it requires only the existing T3 artifacts. The cost is purely documentation: $0.04/unit for the Vietnam OEM’s hazmat clerk time to package and ship the 5-doc PDF bundle to the buyer. Skipping this step is the single most common FBA inbound rejection cause — Amazon’s hazmat review checks the 5 docs, not the 28.

6. Tab T4 — IP protection NNN agreement + USPTO + tooling ownership

T4 is the brand-protection tab. The three core documents are the NNN agreement (Non-disclosure, Non-use, Non-circumvention), the USPTO trademark registration, and the tooling-ownership schedule. The NNN agreement is enforced under Vietnam Penal Code Article 289 for criminal remedies and Vietnamese Civil Code for civil remedies — Article 289 carries 3-7 years’ imprisonment for IP theft, which is the actual deterrent.

Document	Signatories	Term
—	—	—
NNN agreement (with Annex A: tooling ownership schedule)	OEM owner + buyer	5 years from last PO
USPTO trademark registration Class 009 (battery packs) + Class 011 (heated apparel) + Class 025 (garments)	Buyer’s US counsel	10-year registration, renewable
Vietnam NOIP house mark registration (optional, for OEM-side brand protection)	OEM owner	10-year registration
Tooling ownership Schedule B (per-tool transfer with royalty buy-back)	OEM owner + buyer	Co-terminus with NNN
Amazon Brand Registry 2.0 application (USPTO Class 009 + USPTO Class 025)	Buyer’s brand team	Indefinite

The NNN agreement and tooling ownership Schedule A/B together form the enforcement spine for any grey-market takedown. Without the tooling ownership documentation, the buyer cannot prove that the OEM is overproducing on its own tooling — which is the most common grey-market vector in Q4.

Internal link: heated apparel manufacturing IP protection — T4 detailed artifacts and NNN scope.

7. Tab T5 — 7-test product safety binder

T5 is the buyer-side QA tab. The 7 tests are:

1. **UN 38.3** (covered in T3, cross-referenced here)

1. **IEC 62133-2:2017 + AMD1:2021** (covered in T3, cross-referenced here)

1. **UL 2054** (US household / commercial battery pack)

1. **IP67 hipot 500V sealing test** (Vietnam OEM in-house, 30-day cadence)

1. **CPSIA + CA Prop 65** (covered in T1, cross-referenced here)

1. **REACH SVHC + OEKO-TEX 100** (covered in T1, cross-referenced here)

1. **Drop + thermal cycle 500→80%** (in-house, 30-day cadence for the first 3 POs, then 60-day cadence)

The third-party lab choice matters. Intertek, SGS, TÜV Rheinland, and Bureau Veritas are the four lab brands that 95% of Vietnam OEM heated apparel programs use. The Intertek–SGS axis is the most common pairing for the US/EU dual-market, with Intertek handling UN 38.3 + UL 2054 (US-focused) and SGS handling IEC 62133-2 + REACH SVHC (EU-focused). TÜV is used when German retailers demand the TÜV mark specifically. BV is the cheapest of the four but has the longest lead time.

Lab	UN 38.3 lead	IEC 62133-2 lead	REACH SVHC lead	Approximate cost per test series
—	—	—	—	—
Intertek	45-60 days	45-60 days	21-30 days	$9,500-$11,000
SGS	45-60 days	45-60 days	21-30 days	$9,000-$10,500
TÜV Rheinland	60-75 days	45-60 days	21-30 days	$11,000-$13,000
Bureau Veritas	75-90 days	60-75 days	30-45 days	$7,500-$9,000

For Q4 2026, the OEM should be running the T5 cycle in parallel with T2, not after. The 60-day T5 test cycle fits inside the Q4 calendar if started no later than T-60. The “test cadence slip” — where the buyer assumes T5 starts after T1 and T2 complete — is the most common cause of Q4 missed cut-off.

B2B Soft Plant — T5 cost optimisation**: For a 20,000-unit PO, the T5 cost (across all 7 tests) is approximately $32,000-$42,000 depending on lab choice. SGS is the cost-optimal default for a US/EU dual-market PO. TÜV is mandatory only when the German retailer’s compliance team requires it (Aldi, Lidl, Bauhaus). Intertek is the cost-optimal default when the US market is the primary target. The total T5 reserve per 5,000-unit PO is therefore $8,000-$10,500 for a typical Vietnam OEM heated apparel program — added to the FOB line as “T5 testing reserve” at $1.60-$2.10/unit.

8. Tab T6 — GRS-RCS rPET chain of custody + ATIGA eco-procurement

T6 is the EU sustainability tab and the most rapidly evolving tab in the binder. The Global Recycled Standard (GRS) and Recycled Claim Standard (RCS) certification is required by EU retailers (H&M, Decathlon, Zalando) and increasingly by US wholesale buyers (REI, Patagonia). The dual-certification (GRS-RCS) is the working standard for Vietnam OEMs as of Q4 2026.

Document	Issuing body	Validity
—	—	—
GRS-RCS dual certificate	Textile Exchange accredited CB	12 months, annual surveillance audit
rPET ≥ 75% post-consumer attestation (per Transaction Certificate)	Textile Exchange accredited CB	Per PO
ATIGA eco-procurement declaration (substantial transformation + rPET ≥ 75%)	Vietnam OEM + VCCI	Per shipment
5-step GRS-RCS chain-of-custody paper trail (input → processing → manufacturing → distribution → retail)	OEM compliance team	Per PO

The Vietnam OEM’s GRS-RCS chain-of-custody paper trail is the operational core. The trail is 5 steps: (1) input rPET chip supplier attestation, (2) yarn spinning mill TC, (3) fabric knitter TC, (4) garment cut-and-sew TC, (5) finished-goods distributor TC. Each step requires a Transaction Certificate from a Textile Exchange accredited CB. The cumulative lead time is 14-21 days for the full chain if all five TCs are commissioned in parallel; serial commissioning adds 5-7 days per step.

For Q4 2026, the rPET yarn cost adds $1.32/unit vs virgin PET ($3.80/unit premium). The buyer recoups this through two channels: (a) ATIGA substantial-transformation duty saving of $15.89/unit per 5,000-unit PO (per 10/10 P#92), and (b) the EU retailer’s willingness to pay a $5.00-$7.00/unit premium for the GRS-RCS certification. Net effect: the GRS-RCS cycle is margin-positive for the buyer, even before considering the brand-value benefit.

9. Tab T7 — Supplier financing binder

T7 is the financial-controls tab and bridges from cycle 5 (Q4 working capital, milestone billing, supplier credit insurance). For a Q4 2026 Vietnam OEM PO, the financing binder has four components:

Document	Issuing body	Validity
—	—	—
L/C at sight or L/C 30-day usance	Buyer’s bank	Per PO
Milestone billing 30/40/30 schedule	OEM + buyer finance	Per PO
Supplier credit insurance binder (Euler Hermes / Coface / Atradius)	Buyer’s credit insurance broker	12 months
21700 cell allocation reservation contract	OEM + cell vendor	60-65 day deposit-to-delivery window

The milestone billing 30/40/30 schedule is the operational core: 30% deposit at PO confirmation, 40% at ex-factory, 30% at destination-port-of-entry. The Vietnam OEM’s working capital line for a 5,000-unit PO at $28.40 FOB is $142,000 for the 60-65 day deposit-to-delivery window — financed through a combination of the buyer’s L/C (typically 70-80%) and the OEM’s own working capital (20-30%). Supplier credit insurance covers the buyer’s receivable exposure to the OEM in case of OEM default.

B2B Soft Plant — T7 cost-of-quality allocation**: The supplier credit insurance binder costs approximately 0.3-0.5% of the PO value. For a $142,000 PO, this is $426-$710 — a trivial line item that protects the buyer against the OEM’s potential default. The cost-of-quality (COQ) allocation across T1-T6 (compliance reserve) plus T7 (credit insurance) plus T9 (RMA reserve, see §11) totals approximately $1.30/unit for a 5,000-unit PO. This is the working-capital cost of doing a Q4 2026 Vietnam OEM program correctly.

10. Tab T8 — Q4 60-day hero-SKU launch calendar back-planner

T8 is the launch-readiness tab. The 60-day hero-SKU launch calendar is built backwards from the launch date, with T-60 being the start of the Q4 supplier-financing cycle and T-0 being the FBA inbound date. The 14 cut-off steps in the calendar are:

Step	T-day	Action
—	—	—
1	T-60	L/C opening + cell reservation contract
2	T-58	Milestone billing 30% deposit
3	T-55	Yarn forward BOM trace confirmation
4	T-50	Cut-and-sew PO + Vietnam OEM capacity reservation
5	T-45	T1 REACH SVHC + UK REACH commissioning (parallel with T5)
6	T-40	T2 BTN Form B + Section 301 binder refresh
7	T-35	T3 UN 38.3 + IEC 62133-2 commissioning (refresh only)
8	T-30	T5 7-test product safety binder commissioning
9	T-25	PPAP 18-element submission + AQL 2.5/4.0 PPAP lot
10	T-20	AQL inspection + PSI (Pre-Shipment Inspection)
11	T-15	T6 GRS-RCS chain-of-custody TC issuance
12	T-10	Battery pack assembly + SoC ≤30% discharge for air freight
13	T-5	UN3481 hazmat 5-doc FBA pre-flight + FBA inbound scheduling
14	T-0	FBA inbound + T9 RMA reserve activation

The calendar is built around the longest lead-time step (T5 at T-30 to T-15, 30-day cadence). For Q4 2026, the calendar should be started no later than mid-August for a mid-October launch (Black Friday Week starts 27 November 2026, so the FBA inbound target is mid-October).

11. Tab T9 — Post-launch RMA reserve + 6-metric after-sales scorecard

T9 is the after-sales tab. The RMA reserve is a landed-cost line item — for a 5,000-unit PO at $36.81 DDP-FBA (per the cycle-5 freight ladder), the 30-day RMA baseline of 2.8% requires a $5.15/unit reserve ($36.81 × 0.028 × 5 = $5.15; simplified: $5.15/unit). The 6-metric after-sales scorecard tracks:

1. **RMA rate at 30 days** (target: ≤ 2.8%)

1. **RMA rate at 90 days** (target: ≤ 4.5%)

1. **IP67 battery cycle count at 80% capacity** (target: ≥ 500)

1. **AQL-related field defects** (target: ≤ 0.8%)

1. **Customer NPS** (target: ≥ 45)

1. **FBA inbound RMA turnaround** (target: ≤ 14 days from RMA initiation to replacement shipment)

The 6 metrics roll up into a single Q4 program score: pass requires 5 of 6 metrics in spec, with the IP67 battery cycle count being non-negotiable (an IP67 < 500 triggers an automatic CAPA review per the cycle-5 forensic diagnostics playbook).

12. Frequently asked questions

**Q1: Do all nine tabs need to be in the buyer’s Q4 2026 review binder?**

Yes. Amazon FBA hazmat checks 5 of the T3 documents. EU retailers check T1, T5, T6. Brand-protection counsel checks T4. Customs checks T2. Buyer QA checks T5. The buyer’s CFO checks T7. The after-sales lead checks T9. Skipping any tab creates a stakeholder gap.

**Q2: Can the Vietnam OEM hold the binder centrally and ship PDFs on demand?**

Yes, and this is the recommended approach. The OEM’s compliance officer emails the relevant PDF subset within 24 hours of the buyer request. The cost ($0.04/unit per the 10/1 estimate) is built into the OEM’s hazmat clerk budget.

**Q3: What is the difference between GRS and RCS, and does the buyer need both?**

GRS (Global Recycled Standard) requires ≥ 50% recycled content and covers the entire supply chain. RCS (Recycled Claim Standard) only verifies the recycled content claim without the chain-of-custody. EU retailers require GRS. US wholesale buyers accept RCS. For a US/EU dual-market PO, GRS-RCS dual certification is the working standard.

**Q4: How long does the T1 REACH SVHC cycle actually take?**

30-45 days for a full first-pass cycle on a new fabric. 7-10 days for a re-test when the SVHC candidate list updates but the fabric is unchanged. The 7-10 day refresh cycle is the actual Q4 turnaround once the initial cycle has stabilised.

**Q5: Is the Section 301 substantial transformation binder required for every PO?**

No. The binder is refreshed every 6 months or whenever the BOM changes by > 5% (yarn-forward). For PO repeats within the same 6-month window, the existing binder carries over. For a 5,000-unit PO with the same yarn-forward BOM as the prior PO, the binder is a 1-day refresh (sign + date), not a 45-day rebuild.

**Q6: What is the cost saving from Section 301 substantial transformation?**

$7.10/unit for a men’s heated jacket at $28.40 FOB Vietnam, per the 10/2 P#89 estimate. For a 5,000-unit PO, this is $35,500 in duty avoidance — the single largest savings lever in the binder.

**Q7: What happens if the buyer switches cell vendors mid-PO?**

The T3 UN 38.3 cycle restarts at $8,500-$12,000/test series and 60-90 days. The cell vendor switch is the single most expensive mid-PO change. The buyer should commit to a cell vendor in the PO confirmation, not at the ex-factory milestone.

**Q8: How often does the buyer need to update the NNN agreement?**

Every 5 years, co-terminus with the agreement term. For long-running Q4 programs, the NNN agreement is signed at the first PO and auto-renews unless either party gives 90-day notice.

**Q9: Is the T7 supplier credit insurance binder mandatory?**

Not legally, but it is best practice for any PO > $100,000. The buyer-side cost is 0.3-0.5% of the PO value, which is trivial against the receivable-exposure protection.

**Q10: What is the difference between ATIGA and EVFTA for Q4 2026 US-bound shipments?**

ATIGA (ASEAN) covers Vietnam to US. EVFTA (EU-Vietnam) covers Vietnam to EU. For a US-bound PO, ATIGA is the relevant FTA, with $15.89/unit savings per 5,000-unit PO. For EU-bound PO, EVFTA applies.

**Q11: Can the Vietnam OEM hold both the GRS-RCS and the OEKO-TEX 100 certifications?**

Yes, the two certifications are independent. OEKO-TEX 100 covers harmful substance levels. GRS-RCS covers recycled content. A Q4 2026 EU retailer typically requires both.

**Q12: What is the FBA inbound turnaround for a Vietnam OEM heated apparel PO?**

7-10 days from FBA inbound scheduling to the item being live on Amazon. The bottleneck is the UN3481 hazmat 5-doc pre-flight (24-hour review window) and the FBA warehouse receiving queue. For Q4 2026, FBA inbound cut-off is mid-October for Black Friday Week.

13. Conclusion — Q4 2026 closure deliverable handoff

The nine-tab binder is the operational unit of work for a Q4 2026 Vietnam OEM heated apparel program. It is not a theoretical document; it is the actual checklist that buyer-side procurement, OEM compliance, US Customs, EU sustainability, Amazon FBA hazmat, and brand-protection counsel work from. The binder consolidates 28-31 source documents into one operationally usable reference, with a $1.30/unit reserve structure (T1 0.21 + T2 included + T5 1.60-2.10 + T6 0.10 + T7 0.30-0.50 + T9 5.15 — total working-capital cost $7.36-$8.36/unit, but T9 RMA is post-launch and only the upfront T1+T5+T6+T7 reserves of $2.21-$2.91/unit are pre-launch).

The next cron session will close cycle 7 and open cycle 8 (Q1 2027 launch readiness + EU ESPR DPP mandatory 2027 preparation). The cycle-8 deliverable will be a Q1 2027 launch readiness binder that adds the EU ESPR DPP mandatory data submission (mandatory 2027) on top of the existing T1-T9 structure.

14. Cross-format coverage — heated jackets, vests, gloves, hoodies

The nine-tab binder applies equally across the four core Vietnam OEM heated apparel form factors. The buyer-side procurement teams for heated jackets, heated vests, heated gloves, and heated hoodies all face the same T1-T9 dependency stack, but the per-form-factor accent shifts:

Form factor	T1 weight	T3 weight	T6 weight	Most-checked tab by Amazon FBA hazmat
—	—	—	—	—
Heated jacket	High (REACH SVHC fabric)	Highest (largest 21700 pack, 7.2V 6000mAh typical)	High (rPET shell fabric)	T3 + T2
Heated vest	Medium	High (slim 5V 5000mAh pack)	High (rPET liner)	T3 + T2
Heated gloves	Highest (REACH SVHC skin-contact)	High (3.7V 2200mAh micro-pack per glove)	Medium	T1 + T3
Heated hoodies	Medium	Medium-High (5V 4000mAh)	High (rPET fleece)	T3 + T2

For a Q4 2026 buyer-side program manager reviewing a Vietnam OEM PO that mixes all four form factors, the T3 battery pack test summary is the single most duplicated document — each form factor has its own UN 38.3 test series, IEC 62133-2 series, and UL 2054 series. The buyer should commission all four series in parallel, not in series, to fit the Q4 calendar.

15. Hand-off checklist for the buyer’s Q4 program manager
