Costa Rica maintains some of the world's strictest environmental customs laws in 2026 to protect its unique biodiversity. You are strictly prohibited from bringing in fresh agricultural products, including fruits, vegetables, seeds, and plants, as they may carry pests that could devastate local crops. Meat products—including fresh, dried, or even some canned items—are also banned unless they have specific international certifications rarely held by tourists. Additionally, you cannot bring in illicit drugs, weapons, or ammunition without complex prior permits. In 2026, Costa Rica has also tightened its stance on vaping products; while personal use is generally tolerated, importing large quantities of e-liquids for sale is prohibited. Finally, the export of local flora, fauna, or "natural souvenirs" like certain seashells and coral is strictly forbidden when leaving, with heavy fines enforced at the airport.
