Instrument principles:
Dear friend, thank you very much for ordering our products. Our default shipping method is sea or rail. This kind of transportation is door-to-door and does not require customs declaration. The time frame is 45-70 days. You can also choose express delivery. The time limit is 15-30 days. Selecting express delivery requires you to pay additional fees, and express delivery requires you to handle customs declaration fees and customs clearance issues yourself. Of course, when you are dealing with customs clearance, we will assist you with customs clearance and provide you with the required documents for customs clearance. Note: Our service does not include handling customs declaration fees and customs clearance issues arising from express logistics. And during shipping, we do not accept chargebacks or disputes of any kind. If you have any questions after receiving the goods, please contact the seller as soon as possible. We will serve you wholeheartedly, but will not accept disputes submitted in bad faith. Once submitted, we will automatically give up after-sales service by default.
