How can I check if a saree is real silk or synthetic?

Short answer

The quickest trade test is a burn test on a loose thread: real silk burns slowly, smells like burning hair and leaves soft, crushable ash, while polyester melts into a hard bead with a chemical smell. For high-value orders, use a laboratory test.

Ask the supplier for written fibre composition first; reputable traders will tell you. If you want to verify:

  • Burn test: pull a thread from the inside edge, never the visible fabric, and burn it safely over a non-flammable surface.
  • Feel and drape: real silk warms quickly in the hand; synthetics often stay cool and slippery.
  • Lab test: for bulk or export orders, a textile testing lab gives a certified composition.

Accurate fibre content matters for customs duty (silk is HS 5007; synthetic filament fabric is HS 5407) and for labelling laws in most importing countries.
