8. Duty Stack (HS / Duty / VAT)
Every rate below is PENDING — lookup on the Thai Customs Department tariff portal. Tradvolt does not publish a hardcoded rate. The scenario TCO above is pre-duty and will worsen once the duty stack is applied.
| Layer | Rate | Official portal | HS code |
|---|---|---|---|
| Import duty (Thailand national line) | PENDING — lookup | Thai Customs Department tariff portal | PENDING — lookup (likely subheading under Chapter 85 for lithium-ion storage) |
| VAT (Thailand) | PENDING — lookup | Thai Customs Department tariff portal (VAT line) | — |
| Excise / surcharge (if applicable) | PENDING — lookup | Thai Customs Department tariff portal | — |
| Anti-dumping / safeguard | PENDING — lookup | Thai Customs Department tariff portal | — |
| Preferential origin (e.g., RCEP / ACFTA, if claimed) | PENDING — lookup | Thai Customs Department tariff portal + rules of origin | — |
How to confirm: open the Thai Customs Department tariff portal, look up the HS subheading for the specific BYD Battery-Box Premium HVS 10.2 (or equivalent) configuration, and read off the import duty, VAT, and any excise line for the current quarter. For comparison lookups outside Thailand, see EU TARIC, USITC HTS, UK Global Tariff, Japan Customs, Australian Border Force, South African Revenue Service, Ghana Revenue Authority, and Uganda Revenue Authority.
9. Reading the result
The computed 5-year NPV is −2,024.88 USD at an 8% discount rate. Both simple and discounted payback are None within the 5-year horizon; the cost stream of 3,449.30 USD PV exceeds the benefit stream of 1,424.42 USD PV by 2,024.88 USD PV. LCOS is 0.3320 USD/kWh on 13,070.69 kWh discharged (sum of the Energy column). The Thai duty and VAT are not applied in this computed pass; the cost stream will increase once they are, deepening the negative NPV.
For a B2B buyer, this means the base-case avoided-downtime / shifted-energy value used here does not recover the all-in landed cost of one wall-mount 10 kWh LFP unit on a 5-year, 8% basis. To reach payback within 5 years, the buyer must either (a) raise the value-per-kWh-discharged (e.g., higher criticality, time-of-use arbitrage), (b) lower CapEx via a larger MOQ, (c) reduce duty + VAT via a preferential origin, or (d) extend the horizon.

12. FAQ
- Which real OEM model is the reference for LFP-Wall-10kWh?
- The reference SKU is the BYD Battery-Box Premium HVS 10.2 (BYD Company Limited), 10.24 kWh nominal, LiFePO4, wall-mount. Equivalent-class products include the Huawei LUNA2000-10-S0 and the Sungrow SBR096. Spec values must be confirmed against the OEM datasheet before any commercial commitment.
- What HS code applies to a 10 kWh LFP battery imported into Thailand?
- Classify the specific product on the Thai Customs Department tariff portal. Common candidate subheadings sit under Chapter 85 for lithium-ion storage systems; the exact national line is PENDING — lookup.
- Are the duty and VAT rates in this page final?
- No. Every duty and VAT rate on this page is PENDING — lookup. Confirm on the Thai Customs Department tariff portal before quoting landed cost. The scenario TCO figures above are pre-duty.
- Is this page an offer or a quote?
- No. This page is an educational TCO framework only. All CapEx / OpEx / NPV / payback / LCOS / sensitivity figures are ILLUSTRATIVE — NOT A QUOTE. Request a firm quote via the RFQ form.
- Which Incoterms are recommended for a first import from China to Thailand?
- For a first small-volume import into Thailand, FOB Shanghai or Ningbo with a Thai clearing agent is common; CIF Bangkok is also used when the buyer wants a single landed-cost line. Confirm with your logistics partner; see ICC Incoterms 2020.
- Which transport regulations apply to a lithium battery shipment?
- UN 38.3 (UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7) for the test summary, plus IATA DGR for air and IMDG for sea. Confirm classification (UN 3480 / UN 3481) and packing instruction with the freight forwarder.
