Import Guide
Base metals like copper and aluminum have complex classification by alloy and form. Learn the requirements and import tariffs.
Classification depends on purity, alloy, form (unwrought, wire, sheet, tube).
Some aluminum products from China have antidumping duties.
Classify by purity/alloy, form, and dimensions.
Certificate of analysis is essential for correct classification.
Customs may request lab tests to verify composition.
Pay applicable duties and taxes.
Tariffs: unwrought copper 0%, unwrought aluminum 0-5%, manufactures 5-15%. Under USMCA: 0% for most products.
Purity and alloy determine exact classification
Unwrought copper generally has low or zero duty
Check countervailing duties for Chinese aluminum
Chemical analysis certificate is key for classification
