Point XVI of the above-mentioned agreement and article stipulates that electrical and electronic products operating with voltages less than or equal to 24 V are exempt from the presentation of a certificate of conformity if they are contained in the mexican official standards NOM-001-SCFI-1993 (Electronic Apparatus – Household Electronic Apparatus Fed by Different Sources of Electrical Power – Safety Requirements and Testing Methods for Type Approval). NOM-003-SCFI-2000 (Electrical Products – Safety Specifications), NOM-016-SCFI-1993 (Electronic Devices for Office Use Powered By Different Sources of Electrical Energy – Safety Requirements and Testing Methods) et NOM-019-SCFI-1998 (Safety of Data Processing Equipment). On 2 September, the Economic Secretariat published the following amendments to Annex 2.4.1: On 1 October 27, 2020, the Minister of economy published an amendment to Annex 2.4.1 of the General Rules and Criteria of Foreign Trade with regard to the identification of specific harmonized customs codes that must comply with the NOLs upon entry into or departure from the country. There are up to 15 different NOMs that govern health, quality, safety, hygiene, environment, packaging, manuals, instructions and commercial and labelling information for certain products such as textiles, leather, vanilla, health, food and soft drinks, alcoholic beverages, cosmetics, toys, electro alcoholic, domestic and others. In accordance with this Annex, importers must prove their conformity, according to the Customs Code of a product, by adding to the Mexican entry form (pedimento) one or more documents relating to compliance with the name issued by the bodies authorised to do so. This is a good one-stop solution, in which you are able to look at the same law/cases from different angles. Overall, I would consider Lexology a good service. There are different laws, regulations, decrees and rules that contain specific provisions aimed at facilitating trade, exports, imports, trade in goods, etc. .
