I want to know about the issues regarding paints intended for export to Iran

“The statement that “export requires rust-proof paint that is completely lead-free” is inappropriate. It is impossible to make paint completely free of lead and chromium; there is always a certain amount present in it (for example, lead is present in the human body; of course, due to limitations in detection techniques, its level may not always be detected). For paints used in different applications, the requirements and definitions regarding the absence of lead and chromium vary. 1. For electronic and electrical products such as mobile phones, cameras, computers, etc., the EU has the ROHS directive which sets limits on the content of lead and chromium. There are also strict mandatory limits on the heavy metal content in the paints used on these products (ROHS stipulates that the lead content should not exceed 1000 PPM, and this figure refers to the total lead content). The manufacturer must provide a certification of compliance with limits issued by an authoritative body. 2. Toy paint: Both the American ASTM F963 standard and the European Union EN71 standard specify clear limits (requiring a lead content of no more than 90 PPM, with this lead content referring to soluble lead), and manufacturers must provide certification from an authoritative body confirming that these limits are met. Clear standard specifications exist for the lead content requirements of these two types of paint; they are mandatory and must be met. 3. For industrial protective paints, there are currently no mandatory standards in place that set limits on the content of heavy metals such as lead and chromium in these paints (if you come across any such standards or regulations, please share them with me). However, some organizations or companies have taken note of the environmental impact of such paints (or coatings); they consider that when carrying out repairs, if paints with high lead content were used previously (such as red lead paint), relevant environmental regulations require that the paint dust generated be collected and treated, which adds to the costs of repairs. As a result, they have put forward certain requirements, such as limits on VOC content, as well as requirements for paints to be lead- and chromium-free. If foreign manufacturers have requirements regarding lead content, standards should be established; complete lead-free status is not realistic.

This is a pigment; be careful with the resin. It is also necessary to note whether the additive contains
