　　12. Most gold-plated watches are made of 14K gold. When wearing them, avoid contact with chemicals and exhaust gas (such as coal gas, liquefied gas and sulfur soap, etc.). It is best to wipe it with flannel once a week to keep it dry and clean.

　　I don’t know when it started, but when I searched for international express delivery on a certain book, I saw all the ads holding signs saying “XX from China, 10KG = 38 yuan, regardless of whether it is ordinary or not.”in fact freight forwarder Our related products were once praised by users, which is the best self-affirmation of the products. https://www.freeseaship.com/

　　On average, this means less than two yuan per pound. Do you have any idea whether you can get this price?

　　0.jpg

　　Let’s think about it first. This price is impossible even in China, let alone international express delivery. Is it possible?

　　Secondly, families should know that international express delivery does not distinguish between sensitive goods and general goods.

　　In terms of cost alone, sensitive goods are higher than general goods. The fear is that you will be warmly received at the beginning, but then turn your back on them.

　　00.jpg

　　Then there may be such a situation: you don’t find such a shipping company, but you still fall into the trap. How should you avoid these pitfalls?

　　Family members have done their homework, and the key points are as follows! !

　　international shipping

　　1. Check the business license

　　Whether a company is operating in compliance can be determined by checking the company’s qualification certificates, such as whether it has international freight forwarding qualifications and other permissions.

　　2. Be wary of ultra-low prices

　　International express delivery costs cannot be much lower than the market price. Too low quotes often hide traps

　　There may be other charges, such as packaging fees, photo fees, etc., and there may even be extremely expensive additional weight prices, which are more expensive than the generally advertised 60 yuan per kg. Don’t try it at the cost of losing more for a small price. It’s not worth it.

　　3. Whether the price is clearly marked

　　See whether the fee is charged according to the quotation form. Many companies often start charging various fees after the user places an order to the warehouse: handling fees, material fees, labor fees, etc.

　　4. Is there an official website system?

　　Generally, regular shipping companies have their own official website systems. Global Express not only has its own official website but also has a mini program. All package information can be checked, and there will also be exclusive customer service to follow up.

　　5. Pay attention to surcharges

　　Pay special attention to surcharges, which may be more expensive than the freight in a few minutes! You must ask clearly what surcharges there are before placing an order.

　　6. Keep evidence

　　When communicating with the shipping company, keep chat records, quotations, contracts and other evidence in case of emergency.

　　Dear family members, don’t be greedy for small profits. Be sure to keep your eyes open before sending express delivery! After all, it’s all money!

　　Finally, if you still have questions that you don’t understand, or if you have any shipping needs, you can consult us~
