RT null T1 Guidelines on Harmonized System Customs Codes and National Statistical Codes for Energy-Efficient Lighting A1 United Nations Environment Programme, A2 Coyne, Steven K1 custom PB United Nations Environment Programme SN 978-92-807-4050-9 YR 2023 FD 2023-08 LK https://wedocs.unep.org/handle/20.500.11822/43126 UL https://wedocs.unep.org/handle/20.500.11822/43126 NO Harmonised Commodity Description and Coding System (HS) codes are a very effective means for monitoring trade statistics of commodities associated with energy efficient lighting regulations in a country and provide a valuable resource for monitoring, reporting and verification activities for regulatory programmes. As markets transition to LED technology-based lighting products, monitoring commodities based on their 6-digit HS code has become more complex. This guideline supports policymakers in understanding these codes and how they can be used with an additional four-digit national component with nation-centric codes unique to each country’s regulatory and statistical needs to maximize the effectiveness of monitoring, reporting and verification activities.
