The National Defense Authorization Act has been signed into law by President Obama without a controversial amendment covering military branded garments.

The amendment would have required military branded garments sold at US base retail stores to be sourced from companies which have signed the Accord on Fire and Building Safety in Bangladesh.

The amendment, backed by some US Democrat politicians, was drawn up after a number of garments and documents with US Marine insignias were found in the rubble of the Tazreen Fashions factory in Bangladesh.

The factory was destroyed by fire in November 2012, resulting in the deaths of 112 workers.

The Accord on Fire and Building Safety in Bangladesh has so far mainly been signed by European, rather than US, apparel companies.
