Battery Module EOL Grading SOP — CN→ES Corridor (LFP Vertical)

Process SOP | TradVolt Cross-Border Battery Programme | Reference equipment: CATL LFP 280Ah prismatic module (Contemporary Amperex Technology Co., Limited) | Accessed 2026-09-21

Verdict. The end-of-line grading and CN→ES shipment of CATL LFP 280Ah prismatic modules runs as a 12-step SOP (intake → OCV → IR → capacity & grade → AQL → UN 38.3 + P908/P909 pack → documents → FIATA forwarder → ENS → Spanish customs → warehouse → archive), with an expected ~14-day end-to-end timeline by air and ~30 days by sea, based on the EU Customs Trader Portal ENS pre-arrival window, UN 38.3 + UNRTDG P908/P909, and IEC 62619:2022 / EN 62619:2022 referenced below. The buyer must produce the OEM datasheet (CATL 280Ah), UN 38.3 test summary, MSDS, AQL plan per ISO 2859-1, commercial invoice, packing list, AWB/B/L and the ENS data set; the customs broker of record must confirm HS 8507.60, duty (TARIC lookup) and Spanish VAT (Agencia Tributaria) at the time of shipment. Limitations: this page uses CATL's publicly marketed 280Ah LFP prismatic cell family and its public product page as the reference equipment; specific test thresholds (OCV band, IR in mΩ, torque values, SOC window) must be taken from the CATL service manual revision supplied with the lot, and duty/VAT values are PENDING — broker lookup at time of shipment.

1. Scope and Applicability

The SOP applies to LFP battery modules in finished form, packaged for road and ocean transport on the China–Spain trade lane. The reference equipment family for this SOP is the CATL LFP 280Ah prismatic module family; equivalent LFP prismatic modules from other OEMs (e.g., EVE Energy LF280K, BYD Blade-based LFP modules) can be processed under the same 12-step sequence provided their own OEM datasheet, UN 38.3 test summary and service manual revision are substituted in the document checklist. It applies to both air freight and sea freight. Damaged or prototype modules are handled under special packing rules stated below. The SOP does not apply to cells in bulk (Class 9 dangerous goods under a different packing instruction set).

11. Notes and Exceptions

Damaged or defective modules are classified as Class 9 dangerous goods under UN 3480 and are packed to P908 (transport for disposal or recycling) or P909 (production, including for rework) per the UN Recommendations on the Transport of Dangerous Goods, 21st revised edition. Prototype modules follow the same P908 / P909 logic when the design has not completed UN 38.3 testing; otherwise the standard UN 38.3-marked carton set applies.

Air carriers and ocean carriers apply their own acceptance policies on top of the UN rules. Confirm acceptance with the named FIATA member forwarder before issuing the AWB or B/L.

Model assumptions flagged. The reference equipment family is the CATL LFP 280Ah prismatic module (public product page: https://www.catl.com/en/products/energy-storage/). Specific test thresholds used in steps 2–5 — OCV band in mV, IR in mΩ, capacity retention in %, SOC cycling window in %, and busbar / terminal torque values in N·m — are NOT reproduced here from the public product page; they must be taken from the CATL service manual revision supplied with the specific lot. The "5-year" archive period in step 12 follows CATL's typical industrial warranty convention and is a model assumption until confirmed against the warranty document for the lot.

This SOP is informational and is designed to be auditable against the named international standards. It does not replace professional customs, legal or fiscal advice. Confirm duty, VAT, HS classification and dangerous goods acceptance with the relevant authorities and carriers at the time of each shipment. Last reviewed: 2026-09-21.
