# Register products with the fiscal classification > The fiscal type, the NCM, the origin and the CEST of the product are what the tax rule reads in each sale and purchase. In Odoo 18, by KMEE. Fonte: https://docs.kmee.com.br/en/odoo/18.0/funcional/fiscal/cadastrar-produtos-com-classificacao-fiscal/ The fiscal type, the NCM, the origin and the CEST of the product are what the tax rule reads in each sale and purchase. This guide registers goods for resale, manufactured goods with IPI, goods under tax substitution, services, fixed assets and consumables, and the taxable unit of an item sold in boxes. ## Before you start Have the company configured and, in hand, the NCM, the origin and the GTIN of the product as in the vendor's document. For services, the service provider company is configured with the municipal registration. This applies in Brazil with configuration: the NCM, the origin, the CEST and the taxable unit with the conversion factor are registered in the product, and the NCM table, with the IPI rate of each one, is kept by the company in Fiscal > Configuration > Products > NCM. ## Step by step ### 1. Register a product for resale In the Fiscal app, under Product and Service, click Products and New. Type the Product name and, in Barcode, the GTIN. On the Fiscal tab, choose Fiscal Type Goods for Resale, ICMS Origin and the NCM; in Taxable unit, choose Units and in Taxable unit factor, type 1.00. Save with the cloud icon. Example: Organizador de gavetas em aço, bought from an importer in the domestic market (origin 2), NCM 7326.90.90, GTIN 2154087507452. The rule then classifies the item by the NCM and by the origin in the sales and purchases. ### 2. Register a manufactured product with IPI In the company that manufactures, click New in Products, type the Product name and, on the Fiscal tab, choose Fiscal Type Finished Product and the NCM. Save and click the arrow next to the NCM to open its record and check the IPI. The IPI rate comes from the NCM: the product only needs to be classified correctly. Example: Mesa de reunião em madeira, NCM 9403.30.00, made by Garapeira Indústria de Móveis, with IPI of 3.25%. In a sale of 10 units at 1,000.00, the IPI base is 10,000.00 and the IPI is 325.00. ### 3. Register a product under tax substitution Register the product as in the first step and, in the CEST field, choose the code linked to the NCM: the field lists only the CEST of the chosen NCM. Save. The CEST is informed in the NF-e for the items of the ICMS Agreement 142/2018 list and, according to the state and the ICMS ST configuration of the company, the rule calculates the substitution. Example: Luminária de piso LED, goods for resale of Guatambu Móveis, NCM 9405.21.00, CEST 21.124.00 (indoor electric table and floor lamps). ### 4. Register a service In Products, click New and type the Product name. In Product type, choose Service. On the Fiscal tab, in Fiscal Type, choose Services; the service fields then appear. In LC 116 Service Type, choose the item of the list and, in National Taxation Code, choose the code. Save. The service invoice leaves with these codes and the ISS of the city. Example: Montagem de estação de trabalho, of Guatambu Montagem e Serviços, done at the customer's site with the furniture the customer bought: item 14.06 of LC 116/2003 and national code 140601. In São Paulo, the item 14.06 corresponds to the service code 07285, with ISS of 5%. ### 5. Register a fixed asset and a consumable For goods the company buys for its own use, click New in Products, type the Product name and uncheck Sales. On the Fiscal tab, choose Fixed Asset or Consumables and the NCM. The fiscal type defines the credits and the entry CFOP in the purchase: the fixed asset in the state uses CFOP 1.551 and generates ICMS credit taken in 48 monthly parts of 1/48; the consumable uses CFOP 1.556 and has no credit. Example: Estante de aço para o depósito (NCM 9403.20.90, Fixed Asset) and Flanela para limpeza (NCM 6307.10.00, Consumables), both bought by Guatambu Móveis for the store. ### 6. Sell in one unit and tax in another For the item sold in boxes and taxed in units, open the product, go to the Fiscal tab and choose the NCM, the origin and, in Taxable unit, Units (UN) with the factor 4: each box (CX) has 4 chairs. In Invoicing > Customers > Invoices, open the invoice, click Confirm, then Fiscal Details and View XML: 2 CX in the commercial unit and 8 UN at 150.00 in the taxable unit. The DANFE brings the item in both units. Example: Guatambu Móveis sells 2 boxes of Jogo de 4 cadeiras estofadas, NCM 9401.61.00, at 600.00, to Escola Corruíra Ltda, in São Paulo: total 1,200.00. ICMS 12% = 144.00; PIS 0.65% and COFINS 3% on the base of 1,056.00 = 6.86 and 31.68; CBS 0.9% and IBS 0.1% on 1,017.46 = 9.16 and 1.02, informative in 2026, and the total stays 1,200.00. ## Expected result Products and services registered with the fiscal type, NCM, origin, CEST and taxable unit that each sale and purchase needs, so the rule chooses the CFOP, the credits and the taxes of every item. ## If something goes wrong If Fiscal Type is required appears when saving, choose it on the Fiscal tab. If the NCM or the CEST does not appear in the list, check the code with eight digits and the NCM linked to the CEST. If the NF-e is refused for lack of CEST, fill in the CEST in the product and issue again. If the NF-e highlights an IPI different from the expected, check the NCM and the rate in its record. If the service fields do not appear, choose Services in Fiscal Type. If the purchase takes ICMS credit on a consumable, change the Fiscal Type to Consumables and redo the purchase. If the taxable quantity comes out equal to the commercial one, choose the taxable unit and the factor in the product and redo the invoice. ## Continue the process - [Register customers with the fiscal profile](https://docs.kmee.com.br/en/odoo/18.0/funcional/fiscal/cadastrar-clientes-e-fornecedores/) - [Check the taxes and the CFOP before issuing](https://docs.kmee.com.br/en/odoo/18.0/funcional/fiscal/conferir-impostos-e-cfop/)
