China extends NPA tariffs on U.S. imports

China will continue to impose anti-dumping and anti-subsidy duties on imports of n-Propanol (NPA) originating from the United States for five years starting on November 6, 2026. The decision, announced by the commerce ministry, means the existing trade remedy measures will remain in place rather than expire. The extended period covers the same product scope as previous measures, including n-Propanol and its commonly used synonyms such as 1-Propanol and Ethylcarbinol.

The renewed tariffs apply to NPA, a chemical widely used in the production of food packaging materials and as an important component of the electrolyte in lithium batteries for new energy vehicles. By maintaining the duties, authorities aim to address continued concerns about subsidised imports and their impact on domestic producers in China’s NPA industry.

The extended framework keeps substantial anti-dumping duties in place, with rates set between 254.4% and 267.4% on U.S. n-Propanol imports. In addition, anti-subsidy duties will continue to range from 34.2% to 37.7%. These two layers of measures are designed to counter both alleged below-market pricing and government-backed support benefiting the imported products.

Under the continued anti-subsidy regime, importers of U.S.-origin n-Propanol must pay the applicable anti-subsidy tax to Chinese customs when the goods enter the country. The tax is levied ad valorem, using the formula: anti-subsidy tax amount equals the customs-determined dutiable price of the imported goods multiplied by the applicable anti-subsidy rate. Import-stage value-added tax is then calculated on the customs value plus any customs duties and the anti-subsidy tax.

The decision follows expiry review investigations carried out by the commerce ministry after the earlier measures approached their scheduled end. The review examined whether subsidies for U.S.-origin n-Propanol and the resulting damage to China’s NPA industry would continue or reoccur if the measures were allowed to lapse. The ministry concluded that both the subsidisation and the associated injury to domestic producers were likely to persist or emerge again without continued protection.

On the basis of these findings, and in line with provisions of China’s anti-subsidy regulations, the commerce ministry recommended that the anti-subsidy measures remain in force. The Tariff Commission of the State Council adopted this recommendation, deciding that, from November 6, 2026, anti-subsidy taxes on U.S.-origin n-Propanol will continue to be collected for a five-year period. The decision maintains continuity with earlier trade remedy actions, including the product definitions set out in prior official announcements.

With the extension of both anti-dumping and anti-subsidy duties, U.S. exporters of n-Propanol face continued high trade barriers in the Chinese market. Importers must factor in the combined impact of the anti-dumping and anti-subsidy rates, customs duties, and value-added tax on their overall costs. The measures are intended to limit the effects of underpriced or subsidised imports on China’s NPA producers while preserving existing rules governing the product range concerned.
