Barium and strontium compounds in this heading serve distinct industrial niches: barium oxide and hydroxide are used in glass manufacturing, lubricant additives, and sugar refining, while strontium compounds find application in pyrotechnics and specialty ceramics. The US tariff schedule separates strontium compounds (2816401000) from barium compounds (2816402000), and China is the dominant import source across both lines. Importers of Chinese-origin goods should evaluate Section 301 tariff exposure, which applies broadly to inorganic chemicals from China.

Frequently Asked Questions

How are strontium and barium compounds distinguished at the US tariff line level under heading 281640?

The US schedule provides two separate 10-digit lines: 2816401000 for strontium oxides, hydroxides, and peroxides, and 2816402000 for barium oxides, hydroxides, and peroxides. Correct classification requires identifying the specific alkaline earth metal in the product.

Is China a significant source of barium and strontium compounds imported into the US?

Yes, China is the leading supplier under this heading, followed by France and Taiwan. Given China's dominant position, Section 301 tariff measures are a key cost consideration for importers sourcing these compounds.
