Illustrative situation
A box of new T-shirts arrives and the plastic bags smell strongly of chemicals. The buyer worries about customers’ skin and wonders whether to ship the goods, air them or return them.
Main answer
A chemical smell in new garments can come from finishing agents, dyes, coatings, packing materials or damp storage, and smell alone does not prove that a garment is unsafe or safe. Isolate the affected cartons, air a sample, and ask the supplier for test reports and certificates that match the product you received. Keep the packaging and cartons until the question is settled, because they are evidence if you need to claim.
Possible causes
Common sources include finishing agents added for softness or crease resistance, residual dye chemicals, print or coating components, and plastic bags and packing materials. Damp storage can also cause a musty smell that people sometimes confuse with chemicals. Smell strength varies with fabric, quantity and how long the cartons were sealed.
What smell can and cannot show
A smell is a signal to investigate, not a measurement. Some harmful substances have no smell, and some strong smells are harmless. It also depends on individual sensitivity. Treat the smell as a reason to test and to ask about processes, not as evidence of a specific substance.
Immediate steps
Separate the affected cartons, remove a sample from its bag and let it air in a ventilated room for a day or two, then compare. Wash a sample following the care label and check whether the smell goes away. Photograph the packaging and record carton numbers and dates before you contact the supplier.
What to ask the supplier
Ask which finishing and coating processes were used, which chemicals management programme the factory follows, and for test reports for restricted substances. OEKO-TEX STANDARD 100 is a product certification for textiles tested for harmful substances, and you can verify a certificate with the issuer. Check that the certificate covers your article and colour and is still valid. See quality and compliance.
Fact, recommendation, uncertainty
- Established fact
- OEKO-TEX STANDARD 100 is a certification for textiles tested for harmful substances, and certificates are verifiable with the issuer.
- Recommendation
- Quarantine affected cartons, air and wash a sample, and ask for test reports and certificates that cover the product received.
- Uncertainty
- Smell cannot identify a substance or prove harm, so only laboratory testing can answer the safety question.

Sino Finetex Editorial Team Sourcing
Ask the factory how long goods were stored and in what packaging before shipping. Limit: the answer may not explain a chemical origin, so ask for testing. Ask whether the supplier can send the safety data for finishing chemicals used on your lot.
Sino Finetex Editorial Team Product selection
Garments with heavy coatings or prints are more likely to smell, so consider this in product choice. Limit: a coating may be needed for the function you want. Request simple, uncoated finishes for products worn next to skin.
Sino Finetex Editorial Team Quality & care
Compare smell on unopened and aired pieces and note any change after washing. Limit: smell is subjective, so record observations with more than one person. Compare cartons from different pallets, because the smell can be limited to one stack.
