Frequently Asked Questions
What additional costs should I expect when importing parts classified under HTS 841590 beyond the basic duty rate?
Importers of air conditioning parts under this code commonly incur merchandise processing fees (MPF), a 0.3464% ad valorem fee, and may face Section 301 tariffs of 1.4% if the parts originate from China. Furthermore, if the parts contain aluminum or steel, you may be subject to additional duties under Section 232 tariffs.
Are there any specific regulatory compliance certificates required when importing parts for air conditioning machines (HTS 841590) into the United States?
Yes, parts containing or designed for use with refrigerants are subject to EPA regulations under Section 608 of the Clean Air Act. You must ensure the shipment is accompanied by a declaration that the components are either certified as containing no refrigerant or are intended for use with an approved refrigerant, to avoid customs holds and penalties.
What are the key packaging requirements for shipping HTS 841590 air conditioning parts internationally?
Parts must be securely packed in sealed, waterproof containers with adequate cushioning to prevent damage from moisture and vibration. Compressors and coils require specific bracing, while all packages must clearly display the HS code 841590 and a detailed parts list to facilitate customs clearance.
Seasonal Import Trends for Air Conditioning Parts
Imports of parts under HTS 841590 show a clear and strong seasonal pattern, peaking in the late winter and spring months (typically Q1 and Q2) ahead of the summer cooling season. U.S. import data reveals shipment volumes in March, April, and May can be 40-60% higher than in the autumn low period of October and November. This surge is driven by manufacturers and distributors building inventory for wholesalers and contractors who install and service systems before peak demand. Consequently, customs clearance and freight capacity from major manufacturing hubs in Asia can experience delays during this pre-season rush.
Compliance Notes for Air Conditioner Parts (8415.90)
Imported parts classified under 8415.90 are often subject to anti-dumping and countervailing duty (AD/CVD) orders in the United States. For example, the U.S. Department of Commerce has specific AD/CVD orders on unitary air conditioner components from China (Case A-570-090). Importers must ensure their shipments are not covered by these orders or correctly declare the applicable cash deposit rates. Furthermore, many parts, especially those containing motors or compressors, must comply with energy efficiency regulations like the U.S. DOE's standards. Always verify the specific compliance landscape for the country of import and the exact part's origin.
