Pre-Shipment Inspection Checklist (AQL + UN38.3 Re-check) — CN→VN Corridor

Verdict: Use this SOP for any EVSE shipment (AC/DC chargers and any lithium-ion auxiliary battery modules) moving from a Chinese OEM facility to a Vietnamese consignee when the buyer (or seller's appointed agent) is responsible for pre-shipment inspection. Expected cycle time: 5–8 working days from PO date T0. Mandatory sampling: ISO 2859-1 General Inspection Level II, with AQL 1.0 for major defects and AQL 2.5 for minor defects; zero critical defects allowed. Equipment scope: Sungrow AC011E-01 (AC, 11 kW), Sungrow IDC30E (DC fast, 30 kW), Huawei FusionCharge AC 7 kW and Huawei FusionCharge DC 60 kW families, plus EVE Energy LF105 cells used in charger buffer packs. Horizon: as of 2026-09-21. Limitation: this page is process guidance only — it does not replace OEM warranty terms, customs broker rulings, or the underlying sales contract.

This SOP defines the mandatory pre-shipment inspection (PSI) sequence for Sungrow AC011E-01, Sungrow IDC30E, Huawei FusionCharge AC 7 kW and Huawei FusionCharge DC 60 kW units, plus spare parts and EVE Energy LF105 lithium-ion auxiliary battery modules, shipped from Chinese OEM facilities to Vietnamese import consignees. It consolidates statistical sampling per ISO 2859-1, the UN Manual of Tests and Criteria §38.3 transport re-check, and INCOTERMS® 2020 allocation of inspection responsibilities.

1. Scope and Applicability

Applies to all EVSE shipments of Sungrow AC011E-01 (≤ IEC 62196-2 Type 2, 11 kW AC) and Sungrow IDC30E (30 kW DC fast), and to Huawei FusionCharge AC 7 kW and FusionCharge DC 60 kW units exported from CN factories to VN destinations.
Applies to lithium-ion battery modules integrated into or shipped alongside EVSE (e.g., EVE Energy LF105 buffer packs, RFID backup cells).
Not a substitute for in-process or during-production inspections; PSI occurs when production is ≥80% complete and ≥20% packed.

Item	Likely HS heading	Duty rate (VN import)	Source portal
AC EVSE (Sungrow AC011E-01, Huawei FusionCharge AC 7 kW)	8537.10 (control panels) or 8504.40 (static converters) — final classification depends on VN customs ruling	PENDING — lookup at Vietnam Customs Electronic Tariff	Vietnam General Department of Customs — https://www.customs.gov.vn/index.jsp?pageId=8
DC fast charger (Sungrow IDC30E, Huawei FusionCharge DC 60 kW)	8504.40 (static converters) — confirm at classification time	PENDING — lookup	Vietnam General Department of Customs — https://www.customs.gov.vn/index.jsp?pageId=8
Lithium-ion cells (EVE LF105 standalone)	8507.60	PENDING — lookup	Vietnam General Department of Customs — https://www.customs.gov.vn/index.jsp?pageId=8

HS classifications above are indicative only. Final HS assignment, applicable MFN or ACFTA preferential rates, VAT, and any anti-dumping or safeguard duties must be verified by a qualified customs broker at the time of shipment against the official Vietnam Customs Electronic Tariff. Tradvolt does not provide legal or fiscal advice.

UN38.3 summary review (per EVE LF105 shipment)	Per shipment	USD	indicative — 80–120
Form E issuance (CN authority)	Per invoice	CNY	UNCERTAIN — depends on local chamber
AQL rework / re-inspection (if fail)	Per re-visit	USD	indicative — 250–400
Vietnam import duty	Per HS code	% CIF	PENDING — lookup at Vietnam Customs
Vietnam VAT	standard rate	% (D + CIF)	UNCERTAIN — confirm at clearance

All cost figures are indicative and not quotations. Tradvolt will issue binding pricing only against a written Request for Quote.

8. Out-of-Scope / Limitations

This SOP does not replace container loading supervision (CLS) — a separate service is offered.
Pre-shipment inspection does not absolve the supplier of contractual warranties per CISG or the underlying sales contract.
AQL sampling carries an inherent producer's and consumer's risk per ISO 2859-1 Annex A.
Insulation resistance limit (≥ 1 MΩ), carton drop height (0.5 m), and IP ratings referenced are derived from the cited IEC/ISO/OEM documents; if the OEM manual revision on file is stricter, the OEM value prevails — model assumption until the as-shipped revision is matched.
