Key takeaway: Importers of quartz from Malaysia must now certify origin or duty payment for any Chinese content, closing a tariff circumvention route.
What happened
On October 21, 2022, the U.S. DOC issued a final ruling stating quartz surface products manufactured in China and further processed (e.g., cut, polished) in Malaysia are subject to the existing antidumping and countervailing duty orders on Chinese quartz.
Commercial note
Importers and fabricators sourcing quartz slabs from Malaysia must immediately verify the origin of the raw stone. If the slabs originated in China, you are now liable for the corresponding AD/CVD duties. Ensure your Malaysian suppliers provide transparent documentation, and factor potential duty costs into your pricing.
Why it matters for importers, fabricators, and project buyers
This directly impacts supply chain costs and compliance for U.S. buyers using this route. Failure to provide proper certification can lead to customs delays, penalties, and unexpected duty liabilities, affecting project budgets and timelines.
