Explore our premium product line designed to excel under rigorous environments, providing high salt-spray resistance and exact specifications for the Costa Rican electroplating and metal working sectors.
Costa Rica has positioned itself as the leading exporter of medical devices in Latin America and a crucial node in the global advanced manufacturing supply chain. Operating inside special free trade zones like the *Coyol Free Zone* and *Global Park*, manufacturers serve strict global markets requiring compliance with international standards such as ISO 13485 and FDA directives.
Our role as a specialized passivation agent manufacturer is to supply advanced chemical agents that ensure metal parts (from titanium surgical instruments to stainless steel valves and electronic housings) survive severe climatic conditions. Costa Rica's tropical climate—noted for high relative humidity and coastal marine environments—accelerates galvanic and atmospheric corrosion, rendering robust metal passivation essential.
Transitioning from hazardous hexavalent chemicals to eco-friendly, high-performance trivalent formulations that exceed RoHS and REACH standards.
Our trivalent zinc passivation agents (such as the 216 Iridescent Passivation) form a highly dense, hydrophobic chromium-zinc oxide barrier layer. This ensures neutral salt spray test (SST) performance exceeding 300 hours to white rust, matching or exceeding historical hexavalent chromium options.
Global regulatory pressure (especially for medical devices exported to North America and Europe) demands chemical treatments completely free of chromium (VI) and cobalt. Our research and development focus has successfully created zero-cobalt solutions that are non-toxic, safe for workers, and easily treated in wastewater systems.
By incorporating specialized silicon and polymer nanoparticles into the liquid concentrate, our chemical solutions yield self-healing passive films. If a surface is scratched, the surrounding active passivation ions migrate to the raw substrate, sealing it from oxidation.
Suzhou Hiyie Chemical Co., Ltd. runs state-of-the-art production sites in China with secondary R&D nodes in Wuhan and Shanghai. Through our resilient Chinese logistics hub, we guarantee uninterrupted shipping routes to Central America, mitigating potential supply chain disruptions.
We work directly with major logistics operators in Limón and Caldera ports to ensure seamless customs clearance and secure transport of hazardous and non-hazardous chemicals. Furthermore, our flexible manufacturing lines allow us to scale batch sizes depending on demand—assuring stable pricing and lead times for manufacturers operating in Costa Rica.

Get answers to standard questions about chemical shipping, compliance, and application processes for Costa Rica.
Yes. We regularly supply manufacturers in Costa Rica's Free Trade Zones (Zonas Francas). We work with logistics partners to handle export customs, shipping, and direct delivery to your factory floor.
Our trivalent formulations, such as the 216 Iridescent Passivation, are engineered for tropical, coastal, and high-humidity climates. They contain corrosion inhibitors that prevent premature white rust on zinc-plated components under high moisture conditions.
Our citric-acid and nitric-acid passivation chemicals are designed to meet ASTM A967 and ASTM F86 requirements. These processes strip free iron from stainless steel surfaces, creating a passive layer suitable for medical instruments and surgical implants.
We provide comprehensive support for all clients. We assist with initial bath setup, feed rate calculations, and analytical testing methods, and can help troubleshoot quality concerns via video call or by analyzing sent bath samples in our Shanghai lab.
