I. Clarifying the Two Aspects of “Tariffs”
Exporting photovoltaic connectors involves two types of tariffs: export tariffs levied by Chinese Customs at the export stage, and import tariffs levied by the destination country’s customs at the import stage. Under the *Tariff Law of the People’s Republic of my country*, while export tariff rates are established, the rate applicable to the vast majority of electromechanical products is zero; therefore, photovoltaic connectors generally do not incur export tariffs. The primary tax burden at the export stage is Value-Added Tax (VAT), and eligible enterprises may apply for export tax rebates.
The import tariff of the destination country is the figure that requires careful calculation.
II. HS Code Classification is the Prerequisite for Calculation
Import tariffs in the destination country are levied based on the rates corresponding to the product’s HS code; incorrect classification leads directly to incorrect tariff calculations.
Photovoltaic connectors generally fall under Chapter 85 (Electrical Machinery and Equipment) of the *Harmonized Commodity Description and Coding System* (HS), commonly under heading 8536 (apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits, for a voltage not exceeding 1,000 volts).
However, specific 8-digit or 10-digit sub-classifications vary by country, resulting in significant differences in tariff rates. It is recommended to verify the most detailed level of the code based on material, voltage rating, and application via the destination country’s customs website or tariff lookup tools prior to shipment.
If necessary, one may apply to Chinese Customs for a pre-classification ruling to confirm the classification.

How to Calculate Import Tariffs for the Destination Country
Import tariffs are typically levied on an *ad valorem* basis (based on value). The basic formula is: Tax Payable = Taxable Value × Tariff Rate.
The dutiable value is generally based on the Cost, Insurance, and Freight (CIF) price—that is, the value of the goods plus freight and insurance costs; if the transaction is conducted on a Free on Board (FOB) basis, freight and insurance costs must be calculated and added to the value.
Tax rates are determined according to the destination country’s tariff schedule, typically categorized into three tiers: Most-Favored-Nation (MFN) rates, preferential agreement rates, and general rates.
Additionally, taxes such as Value-Added Tax (VAT) are often levied at the import stage; for instance, the EU and many Southeast Asian nations impose VAT or sales tax in addition to customs duties, and these must be factored in when calculating the total landed cost.
IV.
Reducing Tariffs via Certificates of Origin
If China has signed a free trade agreement (FTA) with the destination country, the presentation of a valid Certificate of Origin allows for the application of preferential agreement rates, which are often significantly lower than MFN rates.
Examples include the Regional Comprehensive Economic Partnership (RCEP), as well as the China-ASEAN and China-Australia FTAs, all of which cover photovoltaic-related electrical products.
Certificates of Origin should be issued prior to or at the time of shipment; exporting enterprises can use the “Single Window” preferential origin service platform for international trade to check the agreement rates and rules of origin applicable to their goods in the destination country and apply for certificates online.
Tariff calculations are based on the rates in effect on the date of declaration, and the exchange rate used for assessment is the central parity rate of the RMB published by customs authorities.
V.
Considering Additional Costs from Trade Remedy Measures
Certain markets have implemented trade remedy measures—such as anti-dumping and countervailing duties—against specific photovoltaic products. If a product falls within the scope of these measures, additional duties are levied on top of standard tariffs, potentially leading to a significant increase in the overall tax rate.
Before exporting, companies should verify the destination country’s current trade remedy measures and latest updates, and assess risks by reviewing supply chain traceability documentation.
It is widely recommended within the industry to incorporate the four key factors—classification, tax rate, origin, and trade remedies—into the price quotation process to avoid discovering cost imbalances only after the goods have arrived at the port of destination.
Conclusion
The “calculation method” for export tariffs on photovoltaic connectors is straightforward: there are essentially no export tariffs at the point of departure; the focus lies on import duties in the destination country.
These are determined by the HS code and calculated based on the CIF value, with preferential rates under trade agreements secured via a certificate of origin.
Incorporating this calculation process into standard export workflows establishes a reliable cost baseline for overseas price quotations.
