How to Source Products from China

When you are looking to source products from China, you may be confused or overwhelmed by the process. After all, China is a huge country and different manufacturers make different items. In addition, the language barrier can often be a problem.

You must have the right strategy and avoid common mistakes, or you could miss out on the best opportunities available to you. Follow the steps below to put yourself in the best position to make more money in a shorter amount of time.

1. Research the Market
Your first step is research.

You cannot skip this step if you want to be profitable because many businesses and entrepreneurs are now selling products that compete with each other. If you enter a crowded niche, you will simply struggle to maintain the margins necessary to rise to the top of the crop.

When researching, first find out what the market wants. You can search on Amazon for such as the top 1,000 products in any category.

Once you have found a product that fits the criteria, select two or three that you personally feel you know a lot about already.

When you have a found a top-1000 product with poor marketing that you have experience with, it’s time to move to the next step.

2. Contact Your Chinese Manufacturers
Don’t worry, most reputable manufacturers in China have English speaking support.

Then you can go to Alibaba, a huge website that connects you with thousands of qualified manufacturers in China for any product you could imagine. You can chat with them, search for different criteria (such as years they have been in business, their quality rating, payment options, and more). You should narrow it down to three or four manufacturers that have images of similar products to what you want.

3. Negotiate

Factories make money on large volumes, since their prices are usually low.

Therefore, you must project the idea that you are planning on going big from the start.

Once you have selected the few companies you would be happy buying from, you can send them to get better pricing.

4. Asking for Samples or making orders directly
When you have received the quotes from the final manufacturers who you narrowed it down to, it’s time to pick the best price and order your first round.

You can asking for some samples or place a small order directly. Of course, if you worry about trusty of the supplier, you can hire a third party inspection company to do company or factorty audit for you before transferring money to supplier.

5. Give all the requirements of product to your supplier and waiting for the goods
First, take some great photos of your product (links to step-by-step DIY product photo guide) from every angle you can.

The more photos, and higher quality, the better. This is one of the key ways to make your item stand out in a competitive online marketplace. Hire a photographer or use your own phone if you need to, but make it happen.

Now, you will create a product description. When writing this, you will list the actual features of the physical product.

You must also connect the features, which are simply characteristics, to the real benefits the customer is getting.

6.Doing quality inspection
Hire a third party inspection company to help to do quality inspection before goods leave China.

7. Checking the products after receive
After you receive the goods, you can check by your side again.

8. Re-order or stop this business
After checking the goods, you will come to a conclusion about re-order or stoppinmg the business with your supplier.

Toilet inspection function test standard

Toilet inspection function test standard

1.Odor isolation function

The height of the water seal is greater than 50mm. (The height of the water seal is the distance from the water surface in the toilet to the upper edge of the front of the sewage outlet after the water in the toilet is stationary after flushing

2. Sewage function

Toilet inspection function test standard

Method 1. Put 100 polypropylene balls with a diameter of 19mm and a density of 0.85-0.90 g / dm3 into a toilet bowl filled with water, and then turn on the flush button to rinse and rinse three times. An average of 75 polypropylene spheres were passed through at least three rinses.

Method 2. Put 6 ping-pong balls with a diameter of 38mm into the toilet bowl filled with water and inject about 26 ± 4 grams of water inside, then turn on the flush button and rinse three times. An average of at least 5 ping pongs were washed in three flushes.

3.Wash function

Draw a circle with colored pencils on the washing surface about 30mm below the spray hole of the toilet, and then press the button to rinse. The total length of residual ink after flushing cannot exceed 50mm.

How to test the lamps, the lamps test standard

1.Marking of lamps

When inspection lamps and lanterns should check the mark on lamps and lanterns above all, wait like trademark, model, rated voltage, rated power, judge whether its accord with the use specification of the masses. Marking safety is the basic requirement in the safety performance of lamps and lanterns, among which rated power is particularly important. For example, if a lamp is designed to be 40w, without marking rated power, users are likely to install 60w or 100w bulbs, which may cause shell deformation, insulation damage, even electric shock, and possibly cause fire.

Additional, standard stipulates, the wire minimum cross section that USES on lamps and lanterns is 0.5 square millimeter, some manufacturer is to reduce cost, the traverse sectional area that USES on the product is less than 0.5 square millimeter, make electric wire scorch possibly so, short circuit happens after insulator layer burns out, produce danger. During the inspection, you can see the marks printed on the insulating layer outside the wire on the lamp.

2.Protection against electric shock

Should pay attention to the protection against electric shock, after the lamp is energized, the person should touch the live parts, there is no danger of electric shock. If be incandescent lamps and lanterns (for example droplight, wall lamp), install bulb to go up below the circumstance that is not electrified, if touch with little finger cannot live part, prevent electric shock performance is basically accord with.

The antishock performance of lamps and lanterns does not meet the standard, it is to use the lamp holder that does not meet the requirements or the live parts of lamps and lanterns do not add cover to prevent electric shock protection measures caused by.

3. identification from the structure of the luminaire

There should be no sharp edge at the entrance and exit of the metal pipe after the wire, so as not to cut the wire, resulting in electrification of the metal parts, the risk of electric shock. Table lamp, floor lamp and other movable lamps in the power line entrance should be wire fixator, its role is to prevent the power line push back to hit the heating element, wire overheating caused by melting insulation layer, exposed wire and metal shell contact, shell electrification and lead to electric shock.

4. identification from the accessories used on the luminaire

(1) If the lamps and lanterns with electronic ballast, should choose and buy with abnormal protection of electronic ballast lamps, the so-called abnormal protection refers to the fluorescent line when there is an abnormal state of protection, so that the electronic ballast can still work normally.

(2) Lamps such as the use of inductive ballast, look at the ballast on the logo, try to choose the Tw value of a higher (such as Tw130) especially lamps and lanterns cooling conditions poor, should pay attention to this point. Tw is the rated maximum operating temperature of the ballast coil, at which the ballast can operate continuously for 10 years.

The WHO says a COVID-19 vaccine could be developed by the end of the year

On June 18 local time, WHO chief scientist Sumiya Swaminathan said that at least 200 COVID-19 vaccines are under development and about 10 have entered human trials. Three of them will soon enter phase III clinical trials, including one from China.

Sumiya Swaminathan notes that China has several vaccine candidates, and the results of phase I and II clinical trials show promise.

Sumiya Swaminathan also says one or two successful vaccine candidates could be available by the end of the year. The goal is to have 2 billion doses of vaccine produced by 2021. Fortunately, novel Coronavirus appears to have far fewer mutations than influenza viruses, and the mutations that lead to such critical parts as disease severity and immune response have not yet been shown.
