2818.10.20

Analysis

HTS 2818.10.20 covers in grains, or ground, pulverized or refined under heading 2818 (artificial corundum, whether or not chemically defined; aluminum oxide; aluminum hydroxide). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.

This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.

Within this group the rate runs from duty-free to duty-free. Compared with 2818.30.00 (aluminum hydroxide), which pays duty-free, a misclassification either way moves the duty by 1.3 percentage points.

The general duty rate is 1.3% of the customs value, which is in the middle of the rates in chapter 28 (34th percentile of 274 lines with an ad valorem rate). On a shipment valued at $10,000 that is $130 in duty before any Chapter 99 additions or preference claims.

For statistics it divides in two: 2818.10.20.10 for white, pink or ruby, containing more than 97.5 percent by… and 2818.10.20.90 for other. Both pay the same duty; the suffix records which kind was imported.
