A supplier's quoted unit price is only one part of the cost of importing watch batteries. For Vinnic products, the stated commercial details include a minimum order of 10,000 units, a 30-day delivery estimate, inspection procedures, and sea freight as an available shipping method. Customs duties, taxes, insurance, and destination fees are not specified, so confirm them before placing an order.
Ask for an itemized quotation that makes clear what the battery price covers. Request separate figures, or written confirmation of inclusion, for freight, duties, taxes, insurance, customs clearance, port handling, and delivery to the final destination. The available information does not provide rates for these charges.
Sea freight is listed as an option, described as offering low freight cost per unit and capacity for large loads. However, no shipment-specific freight quote or related handling charges are provided. Confirm the shipping route, charges, and responsibility for each logistics step with the supplier and freight provider.
The stated minimum order quantity for batteries is 10,000 units. Before combining products in one order, check whether the minimum applies to each model or series, or whether several models can count toward the same total. Orders below the stated threshold may require different terms.
The indicated delivery time is 30 days, but its scope is not defined. Ask when the period begins and whether it covers production alone or also shipment and delivery to the destination. Clarifying this point helps align inventory plans and any costs associated with timing.
Vinnic button-cell products include alkaline manganese, manganese dioxide lithium, and silver oxide types. Confirm the exact series and model against the device's requirements before ordering. Alkaline manganese and 0% mercury silver oxide cells are listed for applications including quartz watches, pocket watches, wall clocks, sports stopwatches, and laboratory precision timers. Manganese dioxide lithium cells are listed for compact electronic equipment and backup uses.
The supplier describes three quality checks: 100% inspection on the production line, laboratory sampling and testing, and inspection of incoming raw materials. Ask whether any requested third-party inspection, specialized testing, certification review, or extra documentation would incur additional charges.
Available certifications include ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, and UL certification for lithium batteries in the United States. These credentials can inform supplier due diligence, but they do not indicate that freight, taxes, or other import expenses are included in a product quote.

The information provided does not say that shipping is included. Since sea freight is identified as an available method, request a freight quote or written confirmation that it is covered by the quoted price.
The stated MOQ is 10,000 units. If your purchase includes more than one model or product series, verify whether those quantities can be combined to meet the minimum.
No. Customs duties, taxes, insurance, port charges, clearance fees, and local delivery costs are not specified. Confirm these costs with the supplier and relevant logistics providers before approving the purchase.
Compare offers using the estimated total landed cost, not the unit price alone. Include the 10,000-unit minimum, the 30-day delivery estimate, applicable inspection requirements, and shipping arrangements in your review. Request written confirmation of all costs that are not stated, especially duties, taxes, insurance, and destination handling.
