Analysis
HTS 3822.90.00 covers certified reference materials under heading 3822 (diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory…).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 25% of the 179 tariff lines in chapter 38. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Goods from countries without normal trade relations pay the column 2 rate of 25% instead of nothing, so origin decides between free entry and a 25% duty.
The other lines in the same group are 3822.11.00 (diagnostic or laboratory reagents on a backing, prepared…, duty-free), 3822.12.00 (for Zika and other diseases transmitted by mosquitoes of…, duty-free), 3822.13.00 (for blood-grouping, duty-free) and 3822.19.00 (diagnostic or laboratory reagents on a backing, prepared…, duty-free).
Census statistics map these goods to NAICS 325413 (In-Vitro Diagnostic Substance Manufacturing), an industry of 267 US establishments employing 45,459 people. That is the industry code a US manufacturer of the same product would normally use.
