A confirmed HMRC Advance Tariff Ruling gives The 22:23 CIC clearer import classification for specified Terra A Series residential battery energy storage systems in the UK.
1. What's Been Confirmed — and What Hasn't
The 22:23 Community Interest Company, UK partner and exclusive agent for the specified home energy storage systems, has received an Advance Tariff Ruling from HMRC. It confirms the commodity classification for the specified Terra A Series hybrid residential BESS.
For GeePower, this is a meaningful step in making the Terra A Series accessible to UK households through a clear, documentable import pathway.
2. The Ruling: Key Details
Field | Detail |
ATaR Reference | 600015493 |
Issued by | HMRC Tariff Classification Team |
Issued to | The 22:23 Community Interest Company |
Commodity Code | 8507600090 |
Valid | 07 May 2026 – 06 May 2029 |
Goods Description | Hybrid Home Battery Energy Storage System |
Commercial Denomination | All-in-one hybrid residential BESS – Terra A Series manufactured by GeePower |
Covered Models | GPTE-A-51.2-100 to GPTE-A-51.2-600 |
In practical terms, this gives the importer a documented basis for customs handling across the covered models. It supports better planning around import costs, documentation sequencing, and supply scheduling — and it gives UK partners something concrete to reference when discussing supply arrangements with households and installers.
It does not replace installation assessment, electrical compliance review, or market-specific product documentation. Those remain separate requirements.
3. What This Means for UK Households
Where this ruling makes a real difference is in the overall supply model. The 22:23 CIC's at-cost, community-first approach depends on being able to explain the full cost picture to households without ambiguity. A documented import classification is part of that picture. When the import pathway is easier to explain, the household conversation can stay focused on what actually matters: system suitability, usage patterns, and long-term value.
For UK households, this is progress in a practical sense — a clearer route for bringing the specified systems into the UK, a more transparent cost basis, and fewer unanswered questions around product classification. It's not a fixed price promise, and financial outcomes will vary across different tariff structures, property types, and usage patterns. But it's a step toward the kind of supply clarity that makes at-cost residential battery access workable at scale.
4. The 22:23 CIC as UK Partner

The 22:23 CIC's value in this collaboration isn't distribution. It's trust infrastructure — and that's exactly why GeePower chose to work with them for the UK market.
As a UK Community Interest Company operating on a non-profit, community-focused model, The 22:23 CIC is positioned to have a different kind of conversation with households than a conventional retail channel. Its model centres on at-cost access to home battery systems — not margin. That matters because residential energy storage customers don't only ask whether a battery works. They ask who is supplying it, why the pricing looks the way it does, and whether the process is built around them.
The division of responsibility in this partnership is deliberate. The 22:23 CIC handles local community engagement, household communication, and installer coordination. GeePower supports the product, technical documentation, and supply chain. Neither party is trying to do the other's job — and that clarity is part of what makes it function.
5. The Terra A Series: What the Product Actually Is

The Terra A Series is a modular residential ESS built for 5–30 kWh household storage needs. The models covered by the ATaR run from GPTE-A-51.2-100 to GPTE-A-51.2-600 — one to six battery modules.
The system uses LiFePO4 battery chemistry and an integrated inverter architecture. Key specifications include 6200 W rated output power, pure sine wave output, dual MPPT inputs, RS485 communication, and a 10 ms backup switch time. Capacity expands by adding modules — the product logic is stackable and straightforward.
For daily use: the system supports user-defined off-peak charging and peak-hour discharge schedules. It can draw from the grid during low-tariff periods and supply household loads during higher-tariff periods. Backup power during outages and solar PV input are both supported.
Any certification or compliance reference should be verified against the exact model, configuration, and target market before project discussions begin.

6. One Step in a Longer Process

A working UK route for residential energy storage requires more than product availability. It needs local partnership, customs clarity, installation coordination, transparent documentation, and a supply model households can actually understand.
This collaboration addresses several of those requirements together. The ATaR removes one source of uncertainty — how the specified systems are classified for import. That's not everything, but it's not nothing either.
The remaining work is still practical: site assessment, installation standards, configuration checks, customer education, after-sales coordination.
7. Compliance Note
The ATaR is a customs classification ruling issued to The 22:23 CIC. It confirms classification under commodity code 8507600090 for the specified goods.
Import duty treatment depends on applicable UK tariff measures, import conditions, and customs documentation at the time of import. Buyers, installers, and partners with import-specific questions should consult The 22:23 CIC or a qualified customs professional.
