How the Brazilian government buys glass and window frames
Supply and installation of glass, mirrors, doors, and windows, plus metalwork and carpentry services. The work usually involves on-site measurement before fabrication, which favors nearby suppliers and makes installation time part of the evaluation.
What the tender notice usually requires
- On-site measurement before execution
- Installation included
- Thickness and technical standard as specified in the tender notice
Typical activity code (CNAE): 46.79-6 (wood, hardware, and glass). Make sure the company's registered
business purpose covers the activity before bidding — an incompatible CNAE is grounds for disqualification.
How to prepare to bid in Maranhão
Follow new publications daily: between the notice and the bid deadline there are usually about eight business
days, and much of that time goes into gathering documents. Download the tender notice and the terms of reference
from each tender page, check the specification item by item and work out your minimum price before the bidding
phase — including taxes, freight, payment terms and the margin that makes the contract viable.
Micro and small businesses (ME/EPP) get preferential treatment under Brazilian law: a tie preference, extra time
to fix tax certificates and, in smaller purchases, exclusive participation. See the step-by-step guide
how to participate in a tender.
