2850.00.05

Analysis

HTS 2850.00.05 covers hydrides, nitrides, azides, silicides and borides, whether or not chemically defined, other than compounds which are also carbides of heading 2849: of calcium under heading 2850 (hydrides, nitrides, azides, silicides and borides, whether or not chemically defined…).

Within this group the rate runs from 3.7% to 5.5%. Compared with 2850.00.20 (hydrides, nitrides, azides, silicides and borides, whether or not…), which pays 5.5%, a misclassification either way moves the duty by 5.5 percentage points.

The normal trade relations rate here is zero, shared by about 29% of the 274 tariff lines in chapter 28, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.

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 2850.00.07 (hydrides, nitrides, azides, silicides and borides, whether…, 4.9%), 2850.00.10 (hydrides, nitrides, azides, silicides and borides, whether…, 5.5%), 2850.00.20 (hydrides, nitrides, azides, silicides and borides, whether…, 5.5%) and 2850.00.50 (hydrides, nitrides, azides, silicides and borides, whether…, 3.7%).
