Document type: Process SOP | Module family covered: Jinko Tiger Neo 3.0 (JKM-N-66HL4R-V) and LONGi Hi-MO 7 (LR7-72HGD) | OEM manuals: JKM-TN3-EL-SM rev.2.1 (Jinko) / LR5/6-HM7-EL-SM rev.1.3 (LONGi) | Corridor: China → Kazakhstan | Edition: v1.1
Audience: procurement, QA managers, and customs brokers handling utility-scale PV module shipments from CN manufacturers to KZ project sites. This SOP defines how TradVolt performs in-house electroluminescence (EL) imaging-based quality control before cross-border dispatch for two confirmed product families: the Jinko Tiger Neo 3.0 (TOPCon, 670 W class) and the LONGi Hi-MO 7 (HPBC, 610 W class).
This procedure applies to the two crystalline silicon PV module families explicitly listed below:
It covers pre-dispatch EL imaging, AQL sampling per ISO 2859-1:1999, and customs pre-clearance documentation under DAP or DDP per ICC Incoterms 2020.

| Item | HS code (baseline) | Duty rate (KZ import) | Source / portal |
|---|---|---|---|
| Photovoltaic (solar) cells and modules (assembled) | 8541.43 | PENDING — lookup at time of shipment | Kazakhstan State Revenue Committee — official portal kgd.gov.kz; cross-checked against the Eurasian Economic Commission (EEC) Common Customs Tariff. |
| Parts of PV modules (e.g. junction boxes, frames) — where imported separately | 8541.90 | PENDING — lookup at time of shipment | Same as above. |
Disclaimer: HS classifications above are indicative starting points for the CN→KZ corridor. Final classification, applicable duty rates, VAT, and any exemptions (e.g. for renewable-energy equipment) must be confirmed by the nominated KZ customs broker via the official State Revenue Committee portal (kgd.gov.kz) at the time of shipment. TradVolt does not publish hardcoded duty rates.
Dispatch is executed under the ICC Incoterms® 2020 rule stated on the purchase order (DAP or DDP most common for KZ project sites). For road transport from CN to KZ, TradVolt issues a FIATA FCR or FCT per the carrier used; CMR consignment notes are accepted where the carrier operates CMR.

EL images, AQL sheets, defect tags, QC reports, and customs receipts are retained for the warranty period of the project (typically 12 years for PV modules) on TradVolt's secure archive. Access is restricted to QC and project personnel.
