Release 14 · Maintenance / Process Guide · Audience: B2B green-tech trade operators · Reference equipment: Sungrow SH5/6/8/10/12T three-phase hybrid inverter (5–12 kW; pairs SBH100–400 / SBR064–256) — Reference corridor: China → Latin America · Evidence date: 2026-09-22 · Limitation: indicative only; broker/courier confirmation required for every numeric figure.
Verdict. Follow the 11-step sequence in §1 for a Sungrow SH5–12T three-phase hybrid inverter (5–12 kW, high-voltage battery) moving CN → LATAM. Indicative transit is 25–40 days sea or 3–7 days air; customs clearance adds 2–7 working days. All duty rates, HS subheadings and tax treatment are PENDING broker confirmation. Lithium-battery variants add IATA DGR (air) or IMO IMDG Code (sea) obligations on top of the standard export set.

| 9 | Customs clearance and duty / HS classification at destination. Reference starting point for hybrid inverters under the WCO HS 2022 edition is heading 8504 (static converters) / 8504.40 — PENDING broker confirmation per country. | LATAM customs broker | Export document set, HS code, import licence (if any) | Import declaration, duty receipt | Customs release is granted and any duty is paid or guaranteed. |
| 10 | Arrival output-balance verification at the LATAM warehouse. | LATAM importer / 3PL | CN pre-shipment QC log, regulated AC source, multimeter | Arrival QC log | Arrival readings are within tolerance versus the CN pre-shipment log. |
| 11 | Sign handover, attach all logs to the shipment file, archive for the OEM warranty period (Sungrow standard inverter warranty per the product page terms). | LATAM importer | CN pre-shipment QC log, arrival QC log, BL or AWB | Archived shipment file | Buyer signs handover and the file is stored for the OEM warranty period. |

Important — limits. Any torque value on battery terminals, SOC window for transport (typical industry guidance 30–50 % SoC for lithium shipping per IATA DGR), or DC bus voltage (per SH-series datasheet 100–600 V battery class; SBH100–400 / SBR064–256 battery voltage windows as listed on the respective product pages) must be taken from the exact OEM user manual title + revision printed on the product pages listed above, not from this guide.

Disclaimer. HS classifications, duty rates and tax treatment change by country, by product variant and by trade-agreement status. The values above are placeholders only and must be confirmed by the importer's licensed customs broker or by the destination tax authority before shipping. TradVolt does not provide legal, tax or customs advice.
It refers to keeping the unit's measured output (voltage, frequency, phase relationship and DC bus) within the tolerance band stated by the OEM datasheet, both before shipment from China and on arrival in the destination country in Latin America. For the named Sungrow SH-series reference unit (5–12 kW three-phase hybrid), the SH datasheet shows max efficiency 98 %, PV max 1000 V, 0 ms backup switchover and 200 % DC/AC overload — verify exact tolerance against the specific unit's OEM datasheet + manual revision.
The CN pre-shipment bench test should be done by the supplier's qualified QA staff or a third-party inspector, using a regulated AC source and a calibrated multimeter. The arrival bench test should be done by the importer's qualified electrical staff or a contracted service partner at the LATAM warehouse. TradVolt does not perform the test itself and does not certify the result.
No. The HS code field on this page is marked PENDING. Hybrid inverters can fall under different national subheadings depending on rating, battery integration and intended use (typical starting point 8504.40 under WCO HS 2022). The importer's licensed customs broker, or the destination customs authority, must confirm the correct HS code before the import declaration is filed.
Freight rates, bunker surcharges, destination handling fees and duty rates change by season, lane, carrier and country policy. TradVolt does not publish hard prices in maintenance guides because they would be wrong as soon as the next tariff revision is issued. Use the indicative cost slots to plan budget ranges, then request a firm quote through the corridor RFQ link.
