N.Y.C. Admin. Code § 17-1405: § 17-1405 Recordkeeping requirements for carpet businesses.

Carpet businesses shall not remove the original manufacturer's labels from carpets or carpet cushions unless removal is necessary during installation. Carpet businesses shall obtain documentation from the manufacturer, in a form the department finds acceptable, that all carpet or carpet cushion sold, offered for sale or installed within the city is compliant with the standards set forth in section 17-1404 unless the manufacturer's label otherwise indicates that the carpet or carpet cushion is compliant pursuant to section 17-1406. Such documentation shall be kept on file and available for inspection by consumers and officers and employees of the department or the department of consumer affairs within seventy-two hours of the request. If carpet or carpet cushion is sold outside the city for installation in the city, such documentation shall be available for inspection by consumers and the department at the site upon installation.
