How we quote, invoice, ship and warrant every order — the commercial terms that apply to wholesale buyers.
Last updated: 20 October 2026
BulkHDDHub is the trading name of Guangzhou QingYan Technology Co., Ltd. (广州青炎科技有限公司), a limited liability company registered in Guangzhou, China under Unified Social Credit Code 91440106MAK69C4Q9T, with its registered address at Room 302B1057, Building 1, No. 5 Changxing Road, Tianhe District, Guangzhou, Guangdong 510000, China.
"We", "us" and "our" refer to that entity. "You" refers to the business or sole trader placing an order. These terms apply to every quotation, proforma invoice and shipment unless we agree otherwise in writing on the proforma invoice.
Price bands shown on our catalogue are indicative only. They describe a range for bulk OEM units at the stated minimum quantity, FOB Guangzhou, and they move with nearline drive supply. A band is not an offer and does not create a contract.
The binding figure is the unit price on the proforma invoice we issue for your specific part numbers, quantity, condition grade and destination. A written quotation is valid for 7 calendar days from issue unless it states otherwise, because drive allocation changes weekly.
Unless stated otherwise, prices are in USD per unit for bulk OEM drives (no retail packaging). Prices exclude destination duties, taxes, VAT, import clearance costs, and any bank charges levied outside our bank.
An order is accepted only when we issue a proforma invoice and you confirm it in writing and pay the deposit. Until then we may decline or amend the order.
Every proforma invoice states: part number, capacity, interface, condition grade, quantity, unit price, Incoterm, warranty term, lead time and payment schedule. Please check the condition grade on the invoice — that line, not the product photograph, defines what ships.
30% deposit by T/T on order confirmation to reserve stock, and the remaining 70% before shipment. Goods are released for shipment only after the balance has cleared in our account.
Payment is made to the account named on the proforma invoice, in the currency stated. All bank charges outside our bank are for your account. We will never ask you to pay a different account by email — if you receive such a request, call us on the number in the footer before acting on it.
If the balance is not settled within 14 days of the ready-to-ship notice, we may suspend the order. Storage beyond that period may be charged at cost. Deposits are refundable if we cannot supply the confirmed goods.
The standard minimum is 10 drives per order. For a first order we will ship 5 drives so you can test the drives, the packaging and our paperwork before committing to volume. Mixed part numbers may share the same minimum.
Three grades are supplied, and the grade is stated on both the proforma invoice and the commercial invoice:
Goods shipped match the grade invoiced. A grade other than Brand-New may show cosmetic marks and will not carry an unbroken manufacturer service history. If a grade is critical to your deployment, say so before ordering and we will confirm it in writing.
Brand-New drives: 3 years from delivery. Recertified and Refurbished drives: 12 months from delivery. The warranty is provided by us and runs from the delivery date on the carrier record.
Advance replacement. For a confirmed warranty fault we dispatch a replacement before the faulty unit is returned, subject to stock. If an equivalent unit is unavailable we will offer a refund of the invoiced value of that unit.
Dead on arrival. Report a DOA within 30 days of delivery and we replace or refund it at our cost, including return freight.
To make a claim, send the order number, the serial numbers and a description of the fault with any SMART or diagnostic output. We respond within one working day.
Not covered: physical damage, liquid or electrical surge damage, improper handling or installation, unauthorised firmware modification, removal or tampering with serial labels, and use outside the drive's rated workload or environmental specification.
Manufacturer warranty. Where a drive's serial number remains eligible under Seagate's own warranty, you may also claim directly with Seagate in your region. Our warranty runs in parallel and does not replace it. We do not represent ourselves as a Seagate authorised distributor.
All shipments are made on Incoterms® 2020 terms, normally FOB Guangzhou. EXW, CFR, CIF and DDP can be quoted on request. Risk passes at the point named in the Incoterm; title passes only on full payment.
Lead times on the proforma invoice are estimates. Delays caused by carriers, customs, port congestion or export control checks are outside our control, and we will tell you as soon as we know of one.
Drives are packed in anti-static bulk OEM trays with foam suspension and palletised for volume shipments.
Before the balance is due we send photographs of your actual units together with a serial-number list, so the goods can be checked against the invoice before you pay the balance.
Third-party pre-shipment inspection (SGS, Bureau Veritas, TÜV or your nominated agent) can be arranged at your cost, and we cooperate fully with the inspector.
Visible shortage or transit damage must be reported within 7 days of delivery, with photographs and the carrier's delivery documents. Concealed faults are covered by the warranty above.
You may cancel free of charge within 24 hours of confirming the proforma invoice, provided the goods have not shipped and the deposit has not been applied to a special order.
Bulk OEM goods are not accepted back for non-defective reasons after shipment, except at our discretion and subject to a restocking charge to cover re-testing. Faulty goods are handled under the warranty section, not as returns.
Drives are sold for lawful commercial use. You confirm that you, your company and the end user are not subject to trade restrictions that would prohibit the transaction, and that the goods will not be re-exported in breach of applicable export control or sanctions rules.
Our products are not sold for military, weapons or prohibited surveillance applications. We may ask for an end-use statement for certain destinations.
Our total liability in respect of any order is limited to the invoiced value of that order. We are not liable for loss of data, loss of profit, loss of business or any indirect or consequential loss.
Drives are storage devices, not backups. You are responsible for maintaining independent copies of your data and for testing drives before putting them into production.
Neither party is liable for failure to perform caused by events beyond its reasonable control, including natural disasters, epidemic, war, sanctions, government action, port closure, or sustained failure of transport or power. The affected party will notify the other promptly and the obligation is suspended for the duration of the event.
These terms are governed by the laws of the People's Republic of China. The parties will first attempt to resolve any dispute by good-faith negotiation within 30 days. Failing that, the dispute will be submitted to the competent court at our registered place of business in Guangzhou, Guangdong, China.
