海南正式封关：液化气“零关税”落地

Core Insights - The launch of the Hainan Free Trade Port's full island closure operation on December 18 marks a significant milestone, allowing the first batch of "zero tariff" petrochemical raw materials to be imported through Yangpu Port, the largest maritime gateway for Hainan Free Trade Port [1] Group 1: Cost Reduction Benefits - The successful clearance of the first batch of "zero tariff" petrochemical raw materials signifies that the petrochemical industry can quickly benefit from both zero tariff imports and tax exemptions on value-added processing for domestic sales [1] - Propane has been officially included in the "zero tariff" raw material list for Hainan Free Trade Port, meaning that the tariff cost for propane imported from Hainan is effectively eliminated. In 2025, China's propane imports are projected to be approximately 26.235 million tons, providing a lower-cost procurement window for companies heavily reliant on overseas resources [1] - The processing value-added exemption policy encourages enterprises to utilize "zero tariff" imported materials for deep processing, with a cumulative value-added rate of over 30%, allowing products to enter the domestic market without additional import tariffs [3] Group 2: Impact on Trade Flows - The reduction in policy costs is rapidly changing the trade flow of propane and Hainan's industrial role. Previously, Hainan's annual import volume accounted for less than 3% of the national total, primarily used for ethylene raw material supplementation for local refining companies. This role is undergoing a fundamental transformation post-closure [4] - With the zero tariff advantage, Hainan, particularly Yangpu with its deep-water port, is poised to emerge as a propane distribution and trading center for South China and Southeast Asia. International traders can store propane sourced from the Middle East and the U.S. at lower costs in Hainan and flexibly choose to process locally or distribute to domestic and overseas markets based on price fluctuations [4] - The Hainan closure, through the "dual tax exemption" policy, creates a strong international competitive cost advantage for the propane deep processing industry, particularly for PDH projects, accelerating the concentration of related PDH projects in Hainan [4]
