Last updated: July 2026 dataRefrigerant blends built on the HCFC compounds enumerated in HS subheadings 2903.41 through 2903.48 — but formulated without any CFCs — are classified under tariff line 3827310000. HCFCs are transitional refrigerants under the Montreal Protocol, subject to a phased consumption reduction schedule, and EPA import allowances are required under the Clean Air Act. These blends are commonly used in commercial refrigeration and air-conditioning equipment as interim replacements for fully phased-out CFCs, though the HCFC phase-down timetable is progressively tightening allowable import volumes.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The split reflects the underlying HS structure, which distinguishes HCFC mixtures by the specific HCFC compounds they contain — those from subheadings 2903.41–2903.48 (382731), those from 2903.71–2903.75 (382732), and all other HCFC mixtures not elsewhere specified (382739). Correct classification depends on identifying which HCFC compounds are present in the blend.
EPA allocates consumption allowances annually, and the total pool shrinks each year under the phase-down schedule. Importers and blenders must secure allowances before shipment; once the annual allocation is exhausted, additional imports are not permitted regardless of commercial demand. Early-year procurement and allowance trading are common risk-management strategies.
