FAQ

We are a factory specialised in USB flash drive manufacturing in Shenzhen, China. Your order goes straight to our production line, not through a trading company.

We supply customized USB memory sticks to promotional distributors, corporate buyers and gift companies worldwide.

CCUSB is the brand of chinacustomusb.com. It is not a separate company name and not a retail brand.

Yes. Every drive uses an original NAND flash chip under strict quality control and is tested with dedicated QC software. If a drive is not real capacity, we refund five times the money.

No. Our pricing is based on real capacity and original flash chips, never upgraded or fake chips.

All memory sticks use high-quality NAND flash chips, are tested with dedicated QC software, and are checked for real capacity before shipment. Third-party or pre-shipment inspection can be discussed with our sales team before production.

A write-and-verify (full-capacity) test writes data across the whole drive and reads it back; a fake-capacity drive fails this test. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

In the custom USB industry, common capacities run from 128 MB up to 256 GB, with promotional orders most often using 4 GB to 32 GB. CCUSB lists capacities per model and they differ between models, so tell us the model and the size of the files you plan to preload. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

General industry guidance: USB 2.0 suits giveaways and small documents, while USB 3.x is faster and preferred for large video or software files, and remains backward compatible with USB 2.0 ports. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Formatting and the decimal-to-binary difference between marketing and operating-system units make a drive appear slightly smaller than its label. This is normal across the industry and is not a capacity fault.

USB flash drives are generally plug and play on Windows, macOS and Linux without a driver. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Samples are free of charge if they are in stock and the total sample value is under USD 5 — you only cover the courier freight, preferably on your own DHL / UPS or other freight-collect account.

You pay for the samples and the courier freight by T/T, and we ship as soon as your payment arrives. You may also send your own courier to collect the samples from our company.

Send your purchase order by email, or ask us for a proforma invoice. We reply with an exact quotation first. To prepare your order we need shipping information (company name, street address, phone number, destination airport or sea port, transportation method), product information (model numbers, quantity and unit price), required delivery time, freight payment (collect or prepaid), and your forwarder's contact details if you have one in China or Hong Kong.

It is the document we issue so you can confirm the products, quantities, unit prices, shipping terms and payment details before the order is produced. Payment schedules are agreed with our sales team in the proforma invoice.

Enquiry with quantity, drive style, capacity and branding → exact quotation within one working day → free virtual proof → optional physical sample → purchase order or proforma invoice → production (usually 10 days) → QC testing → shipment by courier, air or ocean. Our sales team confirms each step for your order.

An order can usually be finished in 10 days, and rush orders can be discussed. We cannot promise a specific delivery date in a chat window — tell our sales team your required delivery time and they will confirm what is feasible.

Changes to an order in production are handled by our sales team. Email [email protected] with your order number as early as possible so they can confirm what is still adjustable.

Third-party or pre-shipment inspection is common in bulk importing. If your order requires one, tell our sales team before production so it can be scheduled.

Preloading catalogues, presentations or videos before shipment is a common industry service. The accepted file types, size limit, cut-off date and any charge for your model are confirmed by our sales team. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Send our sales team the model and the file list first; they will tell you the accepted upload method and the cut-off date before production. We cannot take file transfers through a chat window.

Files written before shipment generally cannot be changed remotely afterwards. If you need different content for different recipient groups, tell our sales team before production so the batches can be prepared separately.

Undeletable or non-erasable preloads are a common industry option, sometimes implemented as a read-only or CD-ROM partition while the rest of the drive stays usable. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Dual-partition or CD-ROM-zone setups are common in the industry: one locked zone for your content and one normal removable drive for the recipient. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Autorun-style behaviour is a common industry feature, but modern Windows and macOS versions restrict or disable AutoRun for security reasons, so it is not reliable on all computers. Our USB Webkey category opens a nominated URL instead. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Custom drive icons and volume labels are common industry branding options. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

CCUSB lists Encrypted USB Flash Drive and Fingerprint USB Flash Drive as categories, so secure models exist in our range. Which security feature a model carries, and whether it suits your compliance needs, is confirmed by our sales team. We do not quote encryption standards or guarantee a specific security level here.

Per-unit serialisation and encoded identifiers are common industry options for access control or membership programmes. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

We treat customer artwork and files as customer material. Our site publishes a Privacy Policy and a Copyright Notice. NDA and confidentiality terms are agreed by our sales team, not in chat — email [email protected] with your company details and the team will reply within one working day.

Production file handling and retention are commercial and data-protection matters. If your project is subject to GDPR, CCPA or an internal data policy, raise it with our sales team before sending any files so the handling terms are agreed in writing.

Only supply content you have the right to distribute. Preloaded material must be licensed, and intellectual-property risk sits with the party supplying the files.

Yes — we can arrange courier, air and ocean transportation. The final choice is always yours, and freight depends on quantity, weight, volume, transportation way and destination.

Small shipments under 20 kg usually go by courier; orders from 20 to 500 kg go by air to the airport near you; large volumes usually ship in ocean containers. We confirm the exact freight cost with you before shipping.

Yes. Our order form explicitly asks for your forwarder's contact details if you have one in China or Hong Kong.

Company name, street address, phone number, destination airport or sea port, transportation method, required delivery time, freight payment (collect or prepaid), and your forwarder's contact details if you have one.

Our usual payment term is wire transfer (T/T). We also accept Western Union for urgent and critical orders, L/C for bulk orders (subject to order status), and all major credit cards and PayPal mainly for VIP clients — new clients can be considered depending on the order status.

All major credit cards and PayPal are available mainly for VIP clients; new clients can be considered depending on the order status. Our usual term is T/T. Please confirm the exact detail with our sales team.

Import duties, taxes and clearance responsibilities depend on the destination and the agreed shipping term. These are commercial terms decided with our sales team, not in chat. We can arrange the transportation and prepare the shipping documents.

Commonly a commercial invoice (description, quantity, unit price, total value, HS code, Incoterm), a packing list (cartons, weights, dimensions), a bill of lading for ocean freight or an air waybill for air freight, and a certificate of origin when preferential duty is claimed. Our sales team confirms which documents your shipment will carry.

Certificate-of-origin and preferential-tariff documents are arranged per shipment. Tell our sales team the destination country and the document your broker requires, and they will confirm what can be issued.

In most tariff systems, solid-state non-volatile storage devices fall under HS heading 8523.51 (for example 8523.51.0000 in the US HTS). National subheadings vary, so confirm the exact code with your customs broker or destination authority. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Incoterms such as EXW, FOB, CIF and DDP define where cost, risk and customs responsibility pass from seller to buyer. Under DDP the seller handles duties; under EXW/FOB the buyer normally does. Import duty and VAT depend on the destination and the agreed term. These are commercial terms decided with our sales team.

CE is the conformity mark for many products sold in the European Economic Area (usually EMC and Low Voltage directives for a USB drive); FCC Part 15 regulates unintentional radio-frequency emissions in the US; RoHS restricts hazardous substances; REACH regulates chemicals in plastics, coatings, inks and packaging; WEEE covers waste electrical equipment and take-back. These are regulatory frameworks, not quality awards.

These are market-access marks for the United Kingdom (UKCA), South Korea (KC), Japan (PSE) and Australia/New Zealand (RCM). Which ones apply depends on the destination country and the exact product configuration.

No. ISO 9001 is a factory quality-management system, while BSCI and Sedex/SMETA are social-compliance audits of the factory. They are not product-level certifications and do not replace CE, FCC or RoHS documents for a specific model.

CCUSB product pages list certification fields that differ by model, and documents are issued for the specific model and shipment. We do not confirm or issue a certificate in chat. Email [email protected] with the model number and the destination country, and our sales team will supply the applicable report or certificate.

Ask our sales team for the full report for your model. A useful report includes the report number and date, the tested model, the standards and clauses, the measurement results and the issuing lab's accreditation details.

Many markets require the manufacturer or importer name and address, country of origin, accurate capacity labelling and the applicable regulatory marks on the product or packaging. Confirm the exact requirement with your broker. This is general industry information, not a CCUSB commitment. Please confirm the exact detail with our sales team.

Standard USB flash drives generally do not need a specific import licence, but rules vary by country and labelled or preloaded content can trigger other requirements. Confirm with a licensed customs broker in your destination market.

Yes. Only use logos, trademarks and preloaded content you are licensed to distribute. Counterfeit branding or unlicensed software can lead to shipment seizure or platform takedowns.

6 to 12 months, depending on the product. Unqualified products are replaced free of charge during the warranted period. In addition, every drive is built with real capacity and an original flash chip — if it is not, we refund five times the money.

Flash memory is rated for long-term retention under proper storage, but real life depends on write cycles, temperature and handling. Industry pages commonly claim around 10 years. CCUSB's published warranty is 6 to 12 months depending on the product — that warranty, not an industry claim, is our commitment.
