STH is not operating a public ecommerce checkout through this website. Returns and replacements for offline or business transactions depend on the product, written quotation, delivery acceptance, condition, reason and applicable law.
Draft website policy for implementation. Replace all demonstration contact details, warranty periods, operational promises and company identifiers with verified STH information, then obtain review from a Bangladesh-qualified legal professional before publication.
Different processes
A return, a replacement, a warranty repair and cancellation before delivery are different processes. Approval of one does not automatically create a right to another.
The applicable invoice, quotation, warranty document and signed agreement should be reviewed first.
Inspect on delivery
The receiving party should check package count, model, label, visible condition and obvious shipping damage before signing acceptance where practical.
Visible discrepancy or damage should be recorded immediately with photos, delivery documents and written notice to STH or the authorized seller.
Wrong item or quantity
If the supplied item materially differs from the accepted written order, notify STH promptly and do not install, register, modify or use it.
STH may verify the order and arrange correction, exchange, collection or another appropriate remedy.
Change of mind and business orders
Products sourced, configured, imported, allocated or delivered for a confirmed business order may not be returnable merely because needs changed, subject to the written agreement and any mandatory legal right.
Any discretionary acceptance may require the product to be unused, complete, uninstalled, undamaged, in original packaging and accompanied by records, and may be subject to reasonable handling or logistics costs disclosed before acceptance.
Installed or used products
Installation, charging, registration, use, alteration, programming or connection can affect return eligibility because product condition and resale status change.
A suspected defect in an installed or used product should normally follow the warranty or technical inspection process rather than a simple return.
Batteries and safety
High-energy batteries require controlled handling. Do not send, carry or store a damaged, hot, swollen, leaking, smoking or impacted battery without instructions.
STH may require safety assessment, discharge conditions, special packaging or a designated inspection location.
Parts identification
Customers must provide accurate model, rating, dimensions, connector and application information. Similar-looking parts are not necessarily interchangeable.
Where STH supplied the exact reference requested and the mismatch resulted from incomplete or incorrect customer identification, the outcome depends on the written transaction terms and product condition.
Request procedure
Contact STH or the authorized seller with invoice, product model, serial where applicable, reason, delivery date and clear photographs.
Do not return any product until an authorized return instruction, reference or inspection route is provided.
Condition and included items
Approved returns should include all components, charger, accessories, packaging, documents and promotional items supplied with the product unless instructed otherwise.
Missing, damaged, used or modified items may affect eligibility or value, subject to applicable law.
Refund timing and method
Where a refund is approved, the timing and method follow the written resolution, verification of returned condition and original payment route where appropriate.
Bank, payment, transport or documentation delays outside STH control may affect processing time, but STH should communicate the status reasonably.
Non-excludable rights
Nothing in this policy limits a right or remedy that applicable Bangladesh law does not permit STH to exclude.
The final policy should be aligned with STH’s real sales process and reviewed against the Consumer Rights Protection Act, 2009 and other applicable requirements.
