Trump tariff refunds have officially started as US businesses begin filing claims for money paid under tariffs struck down by the Supreme Court. A new online system went live on Monday, allowing importers and their brokers to request refunds for tariffs the court ruled were imposed without constitutional authority. The system is being run by US Customs and Border Protection. Companies were able to start submitting applications at 8 am through an online portal. The refund process is expected to take time, with payments likely issued within 60 to 90 days after approval. However, officials warn that delays are possible due to system load and technical issues. The case stems from a major ruling by the US Supreme Court. In a 6-3 decision, the court found that President Donald Trump exceeded his authority when he imposed broad import tariffs. The court said he used emergency powers to set trade taxes on goods from nearly all countries, citing trade deficits as a national emergency. The ruling confirmed that only Congress has the power to set taxes. Following the decision, lower courts also supported the idea that businesses should receive refunds. A trade court judge ruled that companies affected by the tariffs are entitled to repayment. This opened the door for a structured refund process now being rolled out nationwide. US Customs and Border Protection estimates that more than 330,000 importers paid around $166 billion in tariffs across millions of shipments. Not all of these payments will qualify immediately for refunds. The first phase focuses on more recent or unfinalized tariff cases. Businesses must register in the electronic system before submitting claims. As of mid-April, more than 56,000 importers had already registered. These companies are linked to potential refunds worth up to $127 billion, including interest, according to agency figures. The Trump tariff refunds process is complex and requires detailed documentation. Companies must list every import entry and provide accurate customs data. Officials warn that even small errors in paperwork could result in rejected claims. Each submission can include thousands of entries, making accuracy essential. Trade and tax experts say the system will require patience. Many businesses are still learning how to navigate the portal. Some reported technical problems during the first day, including slow loading times and difficulty creating accounts. Lawyers working with importers said the system improved later in the day after initial issues. Small and medium businesses are among those most affected. Many of them paid significant tariffs on goods imported from countries such as China, India, Bangladesh, and Peru. One clothing company estimated it paid about $32,000 in tariffs and is now waiting to recover that money. However, business owners say they are unsure how much they will actually get back or how long the process will take. Experts say companies importing mixed goods may face additional challenges. Not all products qualify for refunds under the first phase. Some entries may be partially approved while others are rejected. This means businesses must carefully track each shipment and its tariff status. Despite concerns, officials say the system is designed to process refunds in stages. More recent payments will be handled first, while older cases may take longer. This phased approach is intended to reduce pressure on the system and speed up early payouts. Legal and trade specialists say Customs has been responsive in handling early technical issues. Some companies were able to successfully submit claims after multiple attempts. Officials have encouraged businesses to remain patient as the system stabilizes. The Trump tariff refunds process is expected to have wide economic impact. Some refunds may eventually reach consumers if companies pass savings down the supply chain. However, experts say this will likely happen slowly over time rather than in immediate price changes. The ruling and refund system mark a significant moment in US trade policy. It confirms limits on presidential authority over tariffs and sets a major precedent for future trade actions. It also opens a large financial recovery process for importers affected over several years. As the system continues to roll out, businesses across the country are now watching closely. The final amount refunded and the speed of payments will depend on how smoothly the process runs in the coming months.
