Verdict (answer-first, ~100 words): For the TradVolt BMS-HV-LTC6813 harness kit (cell-tap harness built around the Analog Devices LTC6813-1, controlled by datasheet Rev B (2024-02), §10.2), the buyer should run a 9-step CN→LATAM maintenance-and-shipment process on an ~8 working-day pre-shipment horizon plus 25–45 days sea transit. Decision: ship via standard container with calibration + UN R14 cross-check completed by D-2, customs filed by D-2, vessel cut-off D-1. PENDING items: (i) exact HS sub-heading per WCO HS 2022 explanatory note EN 8548, (ii) destination duty per the national tariff of the LATAM port of entry, (iii) UN R14 type-approval number of the parent vehicle. Evidence date: 2025-03-14. Limitation: this is a process SOP, not a vehicle type-approval opinion.

| Step# | Action | Owner | Input doc | Output doc | Done-when |
|---|---|---|---|---|---|
| 1 | Open supplier shipment pack and reconcile part numbers against the purchase order line for the TradVolt BMS-HV-LTC6813 harness kit; cross-check harness BOM against the Analog Devices LTC6813-1 datasheet Rev B (2024-02) reference designator list. | QC officer | PO + supplier pack + LTC6813-1 datasheet Rev B (2024-02) | Reconciliation sheet | All harness SKUs match the PO and the TradVolt BMS-HV-LTC6813 ordering code. |

| 5 | UN R14 anchorage cross-check: verify that seat/ISOFIX anchorages retain approval with the harness routed as designed (UN R14 consolidated text §3 anchorage geometry). | Homologation officer | UN R14 type-approval certificate copy (ECE/TRANS/505/Rev.3/Add.14) | Cross-check memo | No deviation from the approved routing; file reference recorded. |
| 6 | Pre-export labelling: CE / GB marks, lot number, and warning labels applied per OEM instructions. | Labelling operator | Labelling layout | Labelling photo set | Every pack carries the required marks before crate sealing. |
| 7 | Assemble export document pack: commercial invoice, packing list, COO, MSDS (if Li-ion), UN R14 certificate copy. | Document clerk | Doc-pack template | Export folder | All docs signed and counter-signed. |
| 8 | Customs filing: HS declaration under WCO HS 2022 (explanatory note EN 8548) and duty calculation for the LATAM port of entry per its national tariff. | Customs broker | Commercial invoice + WCO HS 2022 EN 8548 + national tariff of destination | Customs declaration | Declaration accepted by the national customs system. |
| 9 | Container stuffing, line-haul, and arrival handshake; consignee re-runs the isolation test on receipt. | Freight forwarder / LATAM consignee | Packing list + arrival checklist | Receipt log | Consignee counter-signs the receipt log. |

Sea transit windows are indicative; port congestion and customs holds are the most common drivers of variance on the CN→LATAM corridor.

TradVolt does not publish hard prices for any of these slots; each requires an authoritative quote from the named owner.
HS code: PENDING — classify against WCO HS 2022 explanatory note EN 8548 (electrical apparatus for switching/protecting/connecting/control of electrical circuits — wiring harnesses sub-heading) for the exact sub-assembly description.
Duty rate (LATAM destination): PENDING — destination-specific and subject to free-trade-agreement preferences; look up the national tariff of the named port of entry (Santos, Buenaventura, Callao, San Antonio, Buenos Aires) on the customs authority's tariff lookup page for that country.
Disclaimer: HS classification and duty rates are determined by the customs authority of the importing country. TradVolt is not a customs authority; always confirm the classification and any FTA preference with a licensed customs broker or the official national tariff database before invoicing.
UN Regulation No. 14 (ECE/TRANS/505/Rev.3/Add.14) covers anchorages for vehicle seating and ISOFIX systems; harness routing must not interfere with the approved anchorage geometry, hence the maintenance step.
No. The Analog Devices LTC6813-1 datasheet Rev B (2024-02) remains the controlling document for calibration values, torque limits, and isolation test voltages; this guide is a process wrapper around it.
Only if the Analog Devices LTC6813-1 datasheet Rev B (2024-02) §10.2 explicitly permits the lower test voltage. Otherwise the maintenance record will not be accepted by the homologation officer.
The homologation officer signs; the QC officer countersigns when the harness lot is closed. The reference for anchorage geometry is UN R14 consolidated text (ECE/TRANS/505/Rev.3/Add.14).
Use the official national tariff database of the destination country for the named port of entry (see §8) and cross-check any FTA preference (e.g., China–Chile FTA) via the destination's customs authority page. Classification should start from WCO HS 2022 explanatory note EN 8548.
