Certifications that kettlebell manufacturers should have

The best kettlebell manufacturers have to provide quality, safety, and health certificate.


SGS is an internationally recognized certification for kettlebell manufacturers. It is currently the leading verification, authentication, and inspection method in the industry today.

An SGS certificate reveals if a brand produces its products at global standards set by organizations like the World Kettlebell League (WKL). They have determined that these are the requirements necessary to produce safe fitness equipment of this type on a global scale.

Another certificate about quality is ISO that stands for the International Organization of Standardization. They are an international and independent organization in charge of ensuring accurate product quality while also promoting efficiency among services from different countries around the world.

Safety and Health

The OHSAS certificate is crucial to any company manufacturing kettlebells. It ensures your safety and helps enhance performance in this industry as well.

When selecting a supplier, ensure they are certified by meeting these requirements. It has to be public knowledge so that everyone can see how compliant their suppliers are.

What kettlebell types that manufacturers produce?

At least two types of manufacturing the kettlebell :

  • Commercial cast iron kettlebells
  • Competition kettlebells

The difference between these two types lies within their shape and handle diameter. While the commercial kettlebells are usually large in size, rounder in shape, and have more grip space for a better hold, the competition kettlebells tend to be smaller with narrower handles that allow users to gain a stronger grip on them.

Methods that manufacturers do to produce kettlebells

Kettlebells are typically cast from metal in standard-shaped molds. There are two methods to make kettlebells :

  • The single-piece casting, or lost foam casting
  • The two-piece casting

The casting process of lost foam is the best way to make kettlebells because they are stronger, durable, and safer. The two-piece casting, on the other hand, may have an even shorter lifespan.

Kettlebell manufacturers that joint the handles onto the bell are not a safe choice. The risk of injury is much too high, and you have to avoid them at all costs.

Understanding the process of quality control for kettlebell manufacturers

The process of quality control is what any gym equipment or kettlebell manufacturers should have. This fundamental process in factoring the quality equipment is important for :

  • All of the products meet the quality specifications
  • Meeting the regulatory requirements for fitness equipment manufacturing
  • Meeting the client’s requirements
  • Minimize the number of products being returned

Manufacturers will split the manufacturing process into some steps to achieve the best results. The operators, engineers, and manufacturers work together to ensure that every detail of the product’s production goes smoothly from start to finish.

There are many steps in the manufacturing process. First, a product sample is made to test quality control and see if it should be mass-produced or not. If the kettlebell product passes inspection, then manufacturers make more of them.

However, this doesn’t mean that they are perfect because there will likely need to be some modifications before production can start from scratch again.

High-quality grade kettlebell manufacturers will follow these strict guidelines :

  • Create products from high-quality materials such as steel or cast iron
  • Use the single piece casting process
  • Use a single dimension of the bell to provides an appropriate noise level for all weights
  • Apply a high-quality coating to help protect against durability, chips, and rust.
  • Provide a flat finishing
  • Avoid visible seams, holes, or any other kind of construction imperfection

Be wary of any kettlebell manufacturer that doesn’t make an effort to use higher quality materials. You will be able to tell a cheap producer by their product’s uneven weight distribution and weak grip handles.

Where do the China manufacturers ship kettlebells most?

The kettlebell market in China is dedicated to large consumers. Most of China’s clients are located in Europe, Asia, and the U.S, with a recent demand spike due to pandemic situations that left them scrambling for supply.

How much price of wholesale from kettlebell manufacturers?

Gym owners have to be aware that the piece does not pay kettlebells. They are priced according to their weight, starting at $1 per kg, and they depend on your desired quantity of final purchases.

However, you must not always purchase the cheapest kettlebells product but also consider the quality too. The kettlebell is made from steel, or cast iron will last longer. Even if it might cost an extra penny, this investment is worth it because they will last longer than kettlebells that are cheaper but break easily after only a couple of uses.

Do the manufacturers provide documents to export the kettlebells?

Yes, they do. You will find all necessary export documentation in your shipment box. The required documentation is :

  • Contract of sales
  • Invoice
  • Airway bill
  • Certificate of origin
  • Insurance of the products

Before placing an order, you have to consult with the kettlebell manufacturer. The export regulations can be difficult to understand, so make sure that they are clear on precisely what is and isn’t allowed for the destination country.

If there are any problems that occur during transport, this manufacturer cannot help because they only deal in shipping goods from one place to another and not customs or anything else involved after the product leaves their facility.

You will also need a customs agent’s assistance if issues are clearing through customs or hiring someone who has experience dealing with these types of situations before exporting it overseas.

What most helpful payout scheme for kettlebell manufacturers?

It is not uncommon for manufacturers to require a deposit before they will start producing them. It is also true in the gym world, where you will typically pay for your equipment upfront and then have installments due throughout the installation.

Although this can be more expensive, most gyms owner find that the payment scheme gives them better control over budgeting costs with multiple deadlines instead of one lump sum upfront fee.


The deposit is regarded as a warrant from buyers and should be done before the kettlebell production starts. It can be anything from the total price, 0 to 50%, but usually, be 20%.

Quality Control

When you purchase kettlebells from a manufacturer, they may ask for payment after their quality control. It is to ensure the weight and shape of your product are up to standard.

If any errors or issues arise during testing, manufacturers will contact you with the proof before making final adjustments in price, which can be 30 to 50% of the total cost.


You will be given a final payment after inspecting the equipment and delivering it to your country. Usually, you will need to pay about 30% of the total price.

It is essential to know that there are various payment options available for kettlebells, depending on the manufacturer. Some clients may pay 100% in front, while others will make the full payment after they’ve been delivered.

These terms could be negotiated by both parties as needed. All that’s required is communication.

How to build a long-term business relationship with kettlebells manufacturers?

  • Have a good track record with payments
  • Never break a contract

Is it difficult to refund the kettlebells order to the manufacturer if unsatisfied with its quality?

No. If you own a business contract with the manufacturer, following contractual agreements should be enough for an efficient and timely refund or replacement of any products that are found defective in some way.
