China released its own version of RoHS in 2007 which is based upon the EU RoHS [55], but it only applies to imported materials, not exported electronics. It’s important to note that items exported from China to other parts of the world may have chemicals of concern that are banned from use in those countries. In the US for example, there have been several cases of imported goods from China containing chemicals (flame retardants and otherwise) that were banned from use in the US. There are even companies in China which produce flame retardants that are no longer produced in the US and EU because of their negative PBT profiles. It is unclear at this time how the China flame retardant regulations are enforced for domestic vs. export items, but local translation and guidance on Chinese environmental regulations is strongly recommended prior to selling into the Chinese market, or, getting exports of items potentially containing flame retardant chemicals from the Chinese market. An updated version of the China RoHS was issued in 2016, restricting the same six substances as the original EU RoHS. Products and parts that contain restricted substances exceeding limits can still be sold in China but need to be marked as such. A peculiar concept of China RoHS is the “Environment Friendly Use Period” (EFUP) designating the time before any of the RoHS substances might to leak out, causing possible harm to health and the environment. Every product that contains RoHS substances above the maximum permitted concentration is carries an orange circle label composed of two arrows containing a number that indicates the EFUP in years.
