Chemical Reagent Import Duty Rates: US and EU Tariffs for China-Sourced Products

After two decades of sourcing from China, I've seen many importers overlook the fact that chemical reagents often enter the U.S. duty-free—but that doesn't mean the process is risk-free. While the Chinese chemical industry now supplies over a third of global demand, the real challenge lies in navigating veterinary controls, proper HS code classification, and supplier reliability—not just tariff lines.

Import from China – chemical reagents

As we know, the products of the chemical industry are very important for consumer goods production and the motor industry. Chemical reagents are used in the laboratory and experimental work. China is importing those products, so we can source chemical reagents. What are the duty rates on such substances?

EU duty rates on chemical reagents from China

EU duty rates on diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents whether or not on a backing:

• For malaria (3822110000) – 0%
• For Zika and other diseases transmitted by mosquitoes of the genus Aedes (3822120000) – 0%
• For blood-grouping (3822130000) – 0%
• For SARS-CoV virus species (3822190010) – 0%
• Other (3822190090) – 0%

Contrary to medical products, laboratory reagents are subjected to veterinary control.

US tariffs on chemical reagents from China

The good news is that many chemical reagents face 0% tariffs, but don't let that lull you into complacency. Incorrect classification or undocumented suppliers can trigger costly delays and inspections. Before placing your next order, have a China-Check team verify your supplier's credentials and perform a factory inspection to ensure your reagents meet both U.S. Customs and domestic quality standards.

• For malaria (3822.11.00.00) – 0%
• For Zika and other diseases transmitted by mosquitoes of the genus Aedes (3822.12.00.00) – 0%
• For blood-grouping (3822.13.00.00) – 0%
• Containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride (3822.19.00.10) – 0%
• Other (3822.19.00.80) – 0%
