　　Save money and worry!

　　1. Why are taxes and fees generated?

　　In international express delivery, taxes and fees are usually the result of a combination of factors such as the value and type of goods and the import policy of the destination country, and are generally due to the following two points:

　　1) Spot checked by customs

　　2) The total value of the package exceeds the tax point of the destination country

　　2. How to determine whether your express delivery is taxed?

　　1) Generally speaking, if the package is taxed, you will receive a text message/phone reminder from the express company

　　2) Track and query the package logistics information through the logistics company’s official website/third-party logistics query website

　　3) Call 11183 for inquiries

　　3. How to deal with the tax?

　　1) Pay taxes by yourself: If it is convenient, you can choose to go to the designated tax payment location or online platform to pay taxes by yourself.

　　2) Entrust a courier company to pay on your behalf: Some courier companies provide tax payment services. You can contact the courier company to learn about the specific process and fees of the payment.

　　3) Consult the customs or professional institutions: If you have any questions about the tax payment process or tax calculation, you can directly contact the customs or consult a professional customs declaration agency.

　　4. How to avoid being taxed?

　　1) Understand the import policy of the destination country

　　Different countries have different import policies, and there are certain restrictions on the types and quantities of goods. Before sending express delivery, it is best to understand the import policy of the destination country to avoid being taxed due to violations.

　　2) Reasonably declare the value of goods

　　Customs clearance principle: Taxes are collected according to the value of the goods and the tax number.

　　Therefore, when filling out the express delivery form, be sure to accurately and reasonably declare the value of the goods, and do not over- or under-estimate!

　　3) Choose the right mode of transport

　　Different modes of transport will have different taxes and fees. Generally speaking, air transport will have higher taxes and fees, while sea transport will have lower taxes and fees.

　　4) Take advantage of the tax-free quota

　　Many countries have a tax-free quota policy, which means that goods below a certain amount can enter the country tax-free. When sending express delivery, the value of the goods can be controlled within the tax-free quota.

　　5) Choose a reliable shipping company

　　It is also important to choose a shipping company with strong customs clearance capabilities, high service quality, and multiple channels.

　　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 order to facilitate users to have a better experience, shipping agent Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. 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~

　　Generally speaking, the service life of a memory foam pillow is 3-5 years, while the service life of a down pillow or a synthetic pillow may be slightly shorter, at 2-3 years. However, this is only a rough reference, and the actual service life may vary depending on personal usage habits and environmental conditions.However, in other words, we should know more about it. travel pillow memory foam The law of development has brought new vitality to the whole industry and revitalized the market. https://tainengjikang.com/

　　How long is the lifespan of a memory foam pillow?

　　How to judge whether the pillow needs to be replaced

　　First, you can observe the appearance of the pillow. If the surface of the pillow is obviously deformed, dented or discolored, it means that it has lost its original elasticity and support and needs to be replaced. Secondly, you can try to press the pillow. If the pillow feels very hard or very soft, it means that it has lost its original comfort and needs to be replaced. Finally, if your pillow has been used for more than 3 years, it is recommended to replace it even if there is no obvious deformation or dent to ensure its hygiene and function.

　　In terms of pillow maintenance, we should clean the pillowcase regularly to keep the pillow clean and hygienic. For memory foam pillows and down pillows, we cannot wash them directly with water, but should use a vacuum cleaner or professional cleaning tools to clean them. In addition, we should also avoid placing heavy objects on the pillow or sitting on the pillow for a long time to avoid damaging the structure and elasticity of the pillow.
