Steps
Confirm the original AD/CVD orders on Certain Quartz Surface Products from China were published 11 July 2019
Check trade.gov's scope information page for the current product-scope definition of 'quartz surface products'
Review the most recent continuation-of-order determination, published 30 January 2025, confirming the orders remain in force
Check for active administrative reviews — note a 2024-2025 review request from a Malaysia-based respondent was rescinded in May 2026 after CBP found no relevant entries
Cross-check CBP enforcement actions for transshipment evasion (Chinese-origin quartz routed through Malaysia/Vietnam and misclassified) before trusting a supplier's country-of-origin claim on paperwork alone
Known gotchas
CBP has documented cases of Chinese quartz transshipped through Malaysia and Vietnam and misclassified (e.g., as 'crushed glass products') to evade these duties — paperwork claims are not sufficient verification
These AD/CVD orders are separate from the 2026 Section 201 global-safeguard tariff action on quartz surface products — a shop could be subject to both, stacking differently by country
