How to Become a Walmart Vendor

Ten steps to make good business !

Step 1

Choose the program that applies to the products or services you sell. If you plan to apply as a minority- or woman-owned business, your company must supply a current certificate.

Step 2

Register your company with Dun & Bradstreet at, if you have not already done so. Walmart buyers pull a D&B report before deciding whether to accept your business as a vendor. Dun & Bradstreet will assign a number to you upon registration. Include this number in the financial section of the application. Walmart does not accept risk ratings of seven or above. A score of one indicates low risk and nine reflects the highest risk.

Step 3

Download the proposal packet from the Walmart website at and fill it out completely. Requirements include product liability insurance, a copy of the Uniform Code Council that lists your business bar code and sometimes, you must mail a sample of the product with the bar code on it.

Step 4

Submit the application online for the National Supplier Program. Visit your local store manager with the paperwork and a sample product, if your business wishes to participate in the local purchase program. The store manager will notify corporate if he is interested. All other requirements are the same. Call the appropriate phone number listed on the Walmart website for the type of service you provide. Write down the reference number assigned to your application for future use.

Step 5

Respond to the buyer’s request for a meeting or to provide additional information. Sometimes the buyer skips this step if he already has sufficient information.

Step 6

Complete and return the vendor agreement paperwork. After approval, call the Electronic Data Interchange help desk to set up electronic access to the Walmart vendor system. The EDI will set up an electronic work desk within the Walmart vendor database, and assign a temporary pass code so you can access the system.

Step 7

Access your account online and complete the Supplier Agreement. You will find the link to this form on the "New Agreements" tab of your work desk. After approval, the Walmart corporate office will assign a vendor number to your business. It sends the vendor number to your company email and to the buyer with whom you have been working.

  • Plutonium is a heavy gray, metal
  • It look rather like nickel when freshly machined.
  • In air it discolors and soon begins to look like tarnished silver; it turns black. The rate of tarnishing depends on the particular alloy of plutonium and atmospheric humidity, but might typically occur within a day. in a few days then corrosion layer thickness, turns olive-colored, and flakes off as plutonium oxide
  • plutonium metal in pieces like the one shown here is not pyrophoric .it does not burn spontaneously in air
  • Its density 19.86 g/cm3, a little greater than gold.


  • A Soft Silvery metal was discovered in 1885 by Austrian Chemist having symbol Nd and atomic number 60.
  • Classified as a rare earth metal and one of the third most abundant element in earth crust which is mostly  mined in China.
  • Neodymium metal is paramagnetic and when alloyed with iron and boron can form one of the world's most powerful magnetic compounds.
  • Products which have small volume need to have a strong magnetic field requires neodymium to be installed inside such as, loudspeakers, headphones, guitar pick-ups, microphones & mostly computer hard disks.
Pig Iron

  • Pig Iron is the intermediate product of smelting iron ore.
  • Pig Iron contains a large amount of carbon.
  • Pig Iron can also be used to produce Gray Iron. 
  • Pig Iron always contain  foreign substances, among which are Carbon, Silicon, Sulphur, Phosphorus and Manganese besides many others in smaller proportion.

Asphalt from Waste Rubber      

  • A pavement material which is obtained by blending the crumb rubber (produced from recycled scrap tires) into liquid asphalt  that results in extremely high performance binder used in paving process.
  • Techniques for incorporating rubber into asphalt are wet process and dry process.
  • The asphalt market uses ground rubber to modify the asphalt binder used in road paving, resulting in more durable roads.
  • Foremost reason to pick the asphalt rubber is that it holds up better to extreme temperature changes.
  • When compared to conventional asphalt, it is more durable, skid resistant , reduces traffic noise and provides a smooth, quiet ride.



  • Actinium is a radioactive chemical element with atomic number is 89 and it symbol Ac.
  • The chemical behaviour of actinium is similar to that of the rare earths, particularly lanthanum.
  • Although actinium is present in the earth's crust and it is found in only trace amounts. It is one of the ten rarest elements.
  • Actinium glows in the dark as it is so highly radioactive. The glow emitted by actinium is bluish in color.

Iron Based Cellular Material

  • Cellular materials structures have solid surfaces or face sheets and cores with complex architectures which may be more than 95 percent voids.
  •  These are similar to foams, but with a periodic rather than stochastic structure.
  • These materials are designed to maximize load bearing, energy absorbing and thermal dissipation capability while reducing the overall weight of the structure.
  • Cellular structures can also play a significant role in the thermal management in and around heat-producing systems and components.


  • Platinum is a chemical element with the chemical symbol Pt and an atomic number of 78.
  • Platinum has an atomic weight of 195.23, which gives it a density almost as great as gold.

Bone Implant 

  • A bone implant or bone graft is a medical procedure through which a damaged or missing piece of bone is replaced with a graft. 
  • If the graft takes successfully, there is a good chance that the area will heal well.
  • Bone implants may also be used to repair chipped, broken, or severely damaged bones.
  • The implant manufactured must be made of a material that is non-corrosive and that does not produce any immunological reaction.
  • Due to high corrosion resistance, excellent strength and light weight, titanium & its alloys are widely used as implants.
