Phosphor Copper Alloy CuP8
Phosphor copper alloy CuP8 contains approximately 8% phosphorus by weight combined with copper, used in non-ferrous metallurgy for deoxidizing and alloying. Although its phosphorus content is below 15%, it is classified as a phosphide under heading 2853 as an inorganic compound. This tariff item covers phosphides whether or not chemically defined, excluding ferrophosphorus.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the phosphorus content is below 15% and the product is presented as a copper alloy
Copper alloys with less than 15% phosphorus are classified as copper-based alloys under Chapter 74, not as phosphides.

Import Tips & Compliance
• Ensure the phosphorus content is accurately documented on the commercial invoice, as the CBSA may verify the chemical composition
• Consider obtaining a binding tariff classification ruling from the CBSA before your first shipment to avoid delays
• Check if the alloy qualifies for preferential duty treatment under a free trade agreement by providing a valid certificate of origin

2-inch Undoped Gallium Arsenide Test Wafer
A 2-inch undoped gallium arsenide test wafer is used for process control and calibration in semiconductor fabrication. Chapter Note 8 to Chapter 28 states that chemical elements doped for electronics are classified in this chapter only in unworked forms; however, gallium arsenide is a compound, not an element. Undoped wafers cut into discs or wafers fall under heading 3818, not this tariff item.
