On April 7, 2026, a piece of news caused quite a stir in the financial market and foreign trade industry.
In the morning of the same day, the electronic chemicals sector showed a straight upward trend. Among them, Tongyu New Materials (301630.SZ) hit the 20cm daily limit, Dongyue Silicon Materials (300821.SZ) also hit the 20cm daily limit, and Lingwei Technology (301373.SZ) rose by nearly 13%.
Related stocks such as Guangzhou Iron and Steel Gas (688548.SH), Fivotech (688371.SH), Fangbang Shares (688020.SH), Ruilian New Materials (688550.SH), Wanrun Shares (002643.SZ) have followed suit.

Behind this market movement is the 2026 Announcement No. 2 recently jointly issued by the Ministry of Finance and the State Administration of Taxation.
The announcement clarified that starting from April 1, 2026, the value-added tax export rebate policy for photovoltaic, battery and other series of products will be adjusted.
Among them, fluorine chemical-related industrial chain products such as lithium hexafluorophosphate and trichlorethylene are included in the scope of canceling export tax rebates.
The specific list of products involved includes 2404120000 products that do not contain tobacco or reconstituted tobacco, nicotine-containing products that are not burned and smoked, 28269020 lithium hexafluorophosphate, 29032200 trichlorethylene and other categories. The above-mentioned products will no longer be subject to the VAT export rebate policy from April 1.
For relevant foreign trade companies, the cost changes brought about by this policy adjustment have become an established fact, and companies need to make response plans as soon as possible.
In the short term, companies should quickly sort out existing export orders and accelerate orders that can complete customs declaration before April 1 in order to fully enjoy the current tax refund policy.
At the same time, companies also need to recalculate product export costs, negotiate pricing with overseas customers based on adjustments to tax refund rates, and reasonably transfer cost pressures.

From a medium- to long-term perspective, companies need to accelerate the pace of industrial upgrading.
Increase the added value of products through technological innovation, thereby reducing reliance on export tax rebate policies.
In addition, enterprises should also optimize their market layout, actively expand domestic market channels, and achieve dual-cycle development of domestic and foreign markets to offset the cost pressure of overseas exports.
In addition to the impact of the adjustment of export tax rebate policy, the international geopolitical situation is also continuing to ferment.
According to relevant reports, at a press conference held at the White House, U.S. President Trump stated that if Iran fails to “surrender” before 20:00 EST on April 7, he will launch an attack on Iran’s civilian infrastructure.
Trump claimed to destroy bridges and power plants in Iran, and also claimed that “a set of plans has been formulated.” Once launched, “every bridge in Iran will be completely destroyed, and every power plant in Iran will be completely paralyzed.” He even claimed that if the United States is willing, “the entire destruction process will only take four hours.” However, he also claimed that he “does not want this to happen.”
Iran has ruled out the possibility of a temporary ceasefire, emphasizing the need for a permanent end to the conflict. It also demands the formulation of an agreement on safe passage through the Strait of Hormuz, post-war reconstruction, and the lifting of sanctions.
Trump commented that although the proposal was meaningful, it was not good enough.
This geopolitical tension has undoubtedly brought more uncertainty to the global economy and trade.
