Frequently Asked Questions
What is the U.S. antidumping duty requirement for importing industrial liquid filters from China under HTS 8421.29?
The U.S. Department of Commerce has issued an antidumping duty order on certain industrial liquid filters from China. Importers must pay a cash deposit rate at the time of entry, which is currently 2.4% for the 'China-wide entity' rate. You must file the appropriate AD/CVD case number (A-570-119) with U.S. Customs and Border Protection.
How does the filter element material affect the classification of industrial liquid filters under HTS 842129?
The material of the filter element (e.g., ceramic, sintered metal, polymer membrane) is critical for classification. If the filter element is made of ceramic, the entire assembly may be classified under HTS 6909 for ceramic wares if the filter element provides the essential character. For polymer membrane cartridges, the assembly typically remains under 842129 as the machinery provides the essential function.
Similar & Confused HTS Codes for Liquid Filters
Filters for internal combustion engines (8421.23) are a major classification distinction; if your liquid filter is specifically designed for a vehicle or aircraft engine, it does not belong in 8421.29. Laboratory-use filter funnels and similar apparatus often fall under 7017.10 or 8421.99. Furthermore, porous ceramic blocks and plates for filtering are classified in heading 6909, not as machinery. Always verify the primary function and any accompanying machinery to ensure proper classification.
