This SOP defines the controlled sequence for re-certifying an LFP-coupled inverter when Kenya's grid code changes, from receipt of the revised code to on-site recommissioning sign-off. It is intended for project engineers, QA officers, freight forwarders, and clearing agents handling shipments on FCL / LCL sea or air terms.

HS classification — to be confirmed per shipment:
8504.40 — Static converters (typical heading for inverters). Sub-heading depends on rated power and topology; verify against the WCO Harmonized System explanatory notes.8507.60 — Lithium-ion accumulators (LFP cells/modules). UN 3480 / UN 3481 marking still applies.8537 for boards/panels, 8538 for parts). Confirm line by line.Applicable duty and tax rates: PENDING — lookup on the official Kenya Revenue Authority iCMS tariff portal before each shipment. Rates change with the annual Finance Act and with EAC CET amendments.
Official portals to consult:
