Terms of service
The rules for ordering from OnVolume. If anything here is unclear, ask support — open 9am–11pm, every day.
What OnVolume does
OnVolume buys products in China on your behalf and brings them to Bangladesh. You choose the product; our China team confirms stock and price, buys it, checks its quality (QC), and ships it to Dhaka. We are not the manufacturer of the products — the supplier in China is.
Ordering and payment
When you place an order you pay 70% in advance by bKash, using the TrxID. The remaining 30%, plus shipping, is paid on delivery in Dhaka. An order is confirmed only after we verify your advance payment. If the supplier is out of stock, or the price changed before we buy, we tell you before spending more than your advance — and in that case your advance is refunded.
Prices
The price shown on a product page is the product price only. It does not include shipping. Tier prices apply per product: the more pieces you buy, the lower the per-piece price. Prices can change if the supplier changes their price before we buy — in that case we tell you before buying.
Shipping and delivery
Shipping is charged per kg, by category, on the real weight measured in Dhaka after arrival — never on the approximate weight shown on the product page. The minimum chargeable weight is 500 g per parcel. Delivery: by Air 7–14 days (৳790/kg), by Sea 25–35 days (৳490/kg) — you choose at checkout. Customs is handled by us. Some items need approval before we can ship them — ask support first (see How it works).
Your account
You sign in with your mobile number and a one-time code (OTP) sent to that number. Keep your phone and your TrxIDs safe, and tell support at once if you think someone else used your account. You are responsible for giving a correct delivery address and mobile number.
Returns
Returns and refunds follow the Returns page. In short: damaged, wrong or lost item? Tell us within 7 days of delivery with photo proof — free replacement first, or a full refund of your advance if replacement is impossible; resolved within 7–14 days.
Changes to these terms
We may update these terms when the service changes. The current version is always the one on this page. If you keep ordering after a change, the new version applies to new orders.
