Export HS Classification & Ruling Request SOP — Corridor CN→AT

Process / Standard Operating Procedure · Equipment: BYD MC Cube-T30 (5 MWh / 1500 V DC liquid-cooled LFP containerised BESS) · OEM: BYD Energy Storage · Corridor: China → Austria

Verdict (TL;DR). For a single BYD MC Cube-T30 container shipped CN→AT under Incoterms 2020 DAP, the expected working classification is HS 2022 subheading 8507.60 (lithium-ion accumulators) for the LFP battery subsystem, with 8504.40 (static converters/PCS) for the integrated power-conversion enclosure, subject to confirmation by an Austrian BTI ruling. Indicative BTI issue time is 90 calendar days from EU BTI portal acknowledgement, plus 5–6 working days for Tradvolt pre-filing scoping. The buyer receives a classified quotation, a BTI-ready dossier, and the issued ruling archived against the dossier.

1 Scope

This SOP governs how Tradvolt classifies the BYD MC Cube-T30 (5 MWh / 1500 V DC liquid-cooled LFP battery energy-storage system, integrated with a power-conversion enclosure, BMS, thermal-management skid and cabling) and its sub-components exported from the People's Republic of China to Austria under Incoterms 2020 delivery terms, and how it obtains a Binding Tariff Information (BTI) ruling to evidence that classification. The MC Cube family is a C&I / utility-scale containerised LFP product family; cabinet ratings are confirmed with the OEM at RFQ. It is a documentation process page; it does not constitute legal advice.

Steps 8–9 (reconcile, communicate, archive)	1 working day after ruling receipt	Receipt of the issued BTI ruling and availability of the importer of record.

[Claim | Src: European Commission — BTI portal | URL: https://ec.europa.eu/taxation_customs/dds2/ebti/ebti_consultation.jsp | accessed 2026-09-22] — The portal sets out the BTI procedure and the standard information that the applicant must provide; exact issue times depend on the competent authority handling the request.

7 Indicative cost slots

Cost slot	Status	Notes
Internal classification effort (Steps 1–4)	Indicative; charged per project	Scope confirmed at enquiry stage; depends on component count and number of candidate subheadings.
BTI dossier preparation (Step 5)	Indicative; charged per dossier	Includes technical review by Product Engineering.
BTI ruling fee — Austrian competent authority	UNCERTAIN	Fees for BTI decisions are set by the issuing Member State and must be confirmed on the Austrian BMF customs page at the time of filing.
Customs duties and import VAT	UNCERTAIN	Depends on the issued BTI subheading, applicable TARIC measures and any preferential treatment; to be confirmed before contracting.

[Claim | Src: European Commission — BTI portal | URL: https://ec.europa.eu/taxation_customs/dds2/ebti/ebti_consultation.jsp | accessed 2026-09-22] — Fees and procedural rules vary by issuing Member State; applicants consult the relevant national customs authority.

8 Periodic review

The SOP is reviewed whenever one of the following occurs: a new LFP product family is added to the scope (current scope: BYD MC Cube-T30); the World Customs Organization publishes HS amendments relevant to lithium-ion equipment (current edition HS 2022); an EU CN explanatory note changes; or an issued BTI is invalidated. The next review date is recorded in HS_Comms_Note_v1.0.docx.

[Claim | Src: World Customs Organization — HS Nomenclature 2022 edition | URL: https://www.wcoomd.org/en/topics/nomenclature/instrument-and-tools/hs-nomenclature-2022-edition | accessed 2026-09-22] — The WCO manages the Harmonized System nomenclature and its amendments; current edition cited as HS 2022.
