Many overseas buyers often encounter the predicament of "the quoted price looks cheap, but the final bill is much higher." To help you stay within your project budget, this article reveals our true business policy:
How can we identify hidden fees and demand truly transparent pricing?
We have no minimum order quantity requirement; even one piece can be charged at the wholesale price.
What is the typical delivery time? How can I safely negotiate the payment method?
The outer casing has a warranty period of 1-5 years, but what exactly is covered?
This article was written by the BSUMWELL technical team. We insist on transparent pricing, no MOQ, and flexible payment methods, making us your most worry-free source supplier. If you need customized openings or non-standard sizes, please refer to the "OEM Customization Full Process Guide".
In B2B procurement communities (such as Reddit or Alibaba forums), the most common complaint from buyers is about hidden fees.
Bare shell low-price traffic generation: When inquiring about the price, they gave an extremely low unit price for the bare shell, but at the time of settlement, the waterproof cable gland and the mounting brackets were all charged at a higher price.
Packaging Fee "Assassin": They only informed us before shipment that fumigation-free wooden pallets that meet sea freight export standards require an additional payment of several tens of US dollars.
Temporary surcharge on shipping: They only announced the shipping cost increase close to the delivery date, knowing that customers would be unable to cancel their orders.
When we provide you with a quote, we will offer a complete Bill of Materials (BOM). The outer casing, matching waterproof seals, standard installation accessories, and export-standard packaging (such as fumigation-free wooden pallets) will all be listed item by item, with no hidden charges. The unit price you receive is the final price charged upon delivery.

Traditional factories often require a minimum order quantity (MOQ) of 500 or even 1,000 pieces, forcing buyers of small and medium-sized renovation projects or early-stage testing to purchase high-priced retail items.
No MOQ limit: We do not have a minimum order quantity. We accept orders for 1 piece for testing or 10,000 pieces for large EPC projects.
Tiered pricing (discounts available for bulk orders): Although there is no minimum order quantity, we still offer transparent tiered pricing. For example, a reference price for a standard model casing would be as follows:
Purchase quantity (PCS) | Price nature | Advantages |
1 - 49 | Basic wholesale price | Supports trial orders without MOQ and project prototyping testing. |
50 - 499 | Small batch discount price | Suitable for small to medium-sized engineering renovation projects. |
500 - 2,999 | Bulk Discount Price | Suitable for regular distributors to stock up. |
3,000+ | Bulk ex-factory price | Suitable for large-scale EPC centralized procurement and OEM projects. |
(Note: The above is an example price list. Please refer to the official price list provided by the sales team for specific models.)
Real Cases: A European client initially purchased only 3 enclosures for project testing (no MOQ). Because we support small orders, he successfully won the local municipal project. He has since placed repeat orders with us 3 times, purchasing a total of over 1,500 enclosures.
For standard models, our delivery time is strictly controlled within [timeframe].7-15 daysTo prevent delivery delays, we recommend including a late payment compensation clause in the contract. We are committed to taking responsibility for delays.
To accommodate buyers of different sizes, we support the following common payment methods to ensure the safety of your funds:
Payment methods | Applicable Scenarios | Fund Security Statement |
T/T (Telegraphic Transfer) | Regular orders, sample orders | For example, 30% prepayment, and 70% payment before shipment (or upon seeing a copy of the bill of lading). |
L/C (Letter of Credit) | Large-scale projects/EPC procurement | Guaranteed by the bank, payment is made upon receipt of complete and accurate documents, providing protection for both parties. |
Third-party escrow transactions | First-time clients | Payment is released only after the recipient confirms receipt through platforms such as Alibaba Trade Assurance. |
The biggest fear after buying the casing is that the sealing strips will crack and leak after six months. We provide [services/support] for all products. 1 to 5 years The warranty period.
Material type | Recommended warranty period | Core protection scope | Common troubleshooting |
PC/ABS plastic | 1-2 years | The outer casing itself showed no severe deformation, and the foam strips showed no abnormal hardening. | Replacement tape or casing |
Aluminum casing | 1-3 years | The coating does not peel off and the structure does not crack. | Replacement or refund depending on the situation. |
304/316 stainless steel | 3-5 years | The main structure will not suffer corrosion or perforation due to material issues. | 1:1 replacement available |
If the problem is caused by our manufacturing defects (such as foam breakage of the rubber strip, stress cracking of the plastic, or stripped threads), the procedure is as follows:
Photo evidence collection: Please provide photos/videos of the defective product and the batch number on the bottom of the casing.
Confirming responsibility: Our engineers will confirm whether it is a manufacturing defect within 24 hours.
Quick replacement: After confirming that everything is correct, it will be directly added to your new order.1:1We will reissue the item or refund it according to the contract; we will never shirk our responsibility.
Q: I have no minimum order quantity and only want to buy 5 shells. International shipping is too expensive. What should I do?
A: For small orders, we usually use international couriers such as DHL and FedEx. You can provide us with your cash-on-delivery account information, or we can help you find the most cost-effective logistics channel.
Q: Does your quote include a cable gland?
A: Our standard quote includes the housing, standard foam sealing ring, and base. If you require a waterproof connector, please specify the cable outer diameter when requesting a quote, and we will add the cost of the Cable Gland to the BOM as a separate item.
Q: What kind of discount can I get if I place a larger order?
A: We offer tiered pricing. Specific discounts depend on the models and total quantity you purchase. Please contact us anytime to obtain a tiered quote tailored to your project quantity.
Require BOM (Bill of Materials) — When requesting a quote, ask for a complete price that includes accessories and packaging; avoid the trap of offering low prices for bare shells.
Confirm MOQ — Don't be tied down by the "minimum order quantity of 500 pieces"; our no-MOQ policy is always ready to support your trial orders.
Lock-in period — The standard timeframe is 7-15 days, and the contract must clearly state the penalty clause for late payment.
Protect funds — Choose a secure payment method, such as T/T, L/C, or platform guarantee.
Check quality assurance — Confirm the 1-5 year warranty terms for different materials and retain the batch number.
