Frequently Asked Questions
What are the specific labeling and certification requirements for importing double glazed window units into China under HTS 700800?
China requires all imported insulating glass units to have a mandatory China Compulsory Certification (CCC) mark. For architectural windows, you must also provide the official CCC certificate from the manufacturer, issued by a designated Chinese certification body, and the product's permanent labeling must include the factory code, standard, and production date in Chinese.
Does the type of glass used in a double-glazed unit (e.g., tempered, laminated, tinted) change its classification under HTS 7008.00?
No, the specific type of glass panes used does not change the classification, provided the unit remains a 'multiple-walled insulating unit of glass'. HTS 7008.00 covers the assembled unit as a whole, regardless of whether the individual panes are tempered, laminated, or coated, as these are considered a single article of glass. However, if the unit incorporates other functional components like blinds permanently sealed between the panes, it may be classified elsewhere.
Key Alternative Classifications
Double glazed units can be classified under other headings if they are not final 'windows'. For example, sealed insulating glass units (the glass panels themselves) fall under HTS 7008.00.00 as 'multiple-walled insulating units of glass'. The complete windows, once framed, are classified in Chapter 94 (9403.20.00 for wooden frames, 9403.90.00 for other materials like PVC or aluminum). The distinction is critical: the glass units are in Chapter 70, while the finished, assembled window units are in Chapter 94 as 'other furniture and parts'.
