This guide covers the maintenance and replacement process for a Surge Protective Device (SPD) used in a PV system when a replacement part is sourced from China and shipped by ocean carrier to the project location. The equipment family used as an illustrative example throughout is the CITEL DS50VGPVS-600, a Type 2 PV surge protective device with replaceable cartridges, publicly marketed by CITEL. [Claim — see Sources row S1]
Corridor: China (CN) origin → sea freight → overseas destination port.
Item class: SPD replacement part (PV Type 2 surge arrestor module / cartridge; equipment family example: CITEL DS50VGPVS-600).

An SPD replacement part is a plug-in module or cartridge of a Surge Protective Device installed in a PV combiner or inverter. It is replaced when the surge element has reached end-of-life following a surge event or when predictive monitoring indicates degraded clamping performance. The illustrative equipment family used in this guide is the CITEL DS50VGPVS-600, a Type 2 PV SPD certified to IEC 61643-31:2018 (edition 1.0, 2018-02). [Claim — see Sources row S1; standard reference S4]
When the replacement part is supplied from China, an exporter at the CN origin compiles export documents, the freight is consolidated at a CN port, and the part moves by sea to the destination port. The corridor definition in this guide is geographic / logistical, not a market-share claim. Where a specific part is manufactured is not stated by CITEL on the public DS50VGPVS-600 product page and must be confirmed with the supplier at RFQ. [Claim — see Sources rows S1, S5]
A commercial invoice, packing list, bill of lading or sea waybill, certificate of origin, and any test/certification documents requested by the destination authority are typically required. ISPM 15 compliance is required for any wood packaging under IPPC ISPM 15. Exact requirements vary by destination and must be confirmed with the destination customs authority before shipment. [Claim — see Sources rows S3, S6]
The total indicative duration shown in the timeline table is approximately 21 calendar days, dominated by sea transit and customs clearance. Air freight is faster but is not covered by this R14 guide. Sea transit durations are not stated by CITEL and depend on trade lane, carrier service and destination port congestion. [Claim — see Sources row S7; limitation noted]
No. R14 covers the sea-freight process only. An air-freight variant would use a separate IATA documentation chain (IATA Cargo Dangerous Goods Regulations programme if applicable) and a different customs channel at destination. [Claim — see Sources row S8]
