  5. Benefits of working with a small company that interacts with customers

    Leave a Comment

    Customer service is the main reason consumers choose small businesses over their larger competitors. Their top requirements are for personalized interactions and the supplier’s extensive knowledge of customers’ needs. Today’s business conditions often require suppliers to be agile and able to respond to changes in the market at short notice. This is where small businesses come into their own and why we at Jefferson strive to always keep the customer front and center.

    Why work with a small company?

    #1 – Culture

    Smaller companies are likely to be run by management and staff who have taken the company from a start-up business to become a reputable supplier. During this process, the company will have developed a corporate culture that its employees fully understand and subscribe to. Corporate culture forms a big part of the brand that customers identify and will want to work with.

    #2 – Customer Relationships

    The customer is the reason for the business. Smaller businesses and their customer-facing staff are more sensitive to this fact than their larger competitors. Customers are more likely to be dealing with the same person regularly when dealing with a smaller company and, in the process, develop closer inter-personal relationships. The person responding to the customer call in a small business is also likely to be an owner or someone who has a deep understanding of the company, its products and be a decision-maker, This makes them able to attend to a customer’s requirements immediately.

    #3 – Flexibility

    Small companies are inherently more flexible than their larger competitors. The decision-making process is shorter and often only involves a single person. They are, therefore, able to react quickly to any change in customer requirements or any potential problem arising from an order. These businesses have also learned that their survival depends on being able to respond rapidly to changing market conditions or lapses by competitors.

    #4 – Specialization

    Smaller businesses tend to focus on niche markets where either their specialized knowledge or unique products set them apart from their competitors. By specializing, a small business can often charge a premium for their products and improve margins. Being a specialist in a specific field and delivering a quality product are essential factors in ensuring the sustainability of a small enterprise.

    #5 – Communication

    Well run smaller businesses place a significant emphasis on internal and external communications. They focus on regular communication and feedback to their clients while at the same time keeping their staff well informed of the latest developments and changes in customer requirements. They also stay abreast of the latest technology and communication aids and incorporate their customer’s needs into these systems.

    #6 – Employee Engagement

    Staff in smaller companies tend to have a closer relationship with their employer than might be the case in a larger business. Although opportunities for advancement may not be as readily available as in more prominent companies, levels of commitment to quality and meeting production targets are often very high. They are also open to cross-skilling which adds to employee satisfaction levels and ultimately to a better understanding of customer needs.

    Jefferson Rubber Works is a leading supplier of custom rubber products based in the United States of America. Their highly skilled staff and a company with more than 40 years of experience can meet every custom rubber molded injection requirement. They will give you a fuss-free “one-stop shop” experience from concept and design to the final high-quality product you need.

  6. Tarrifs

    Leave a Comment

    Understanding different tariffs and duties in important for US businesses as it helps to give context to buying locally made products that don’t have the same high taxation rates. Tariffs or duties are taxes imposed on imports or exports between countries. The primary aim of an import tariff is to regulate foreign trade. Import tariffs are a part of a government’s policy that taxes foreign products to encourage or protect domestic industries and businesses. They serve as a source of income for governments, much the same as various other forms of consumption taxes.

    The tariffs that the government of the United States of America are applying to imported goods and services from countries across the globe are intended to support local American industries and increase employment opportunities.

    Learn more about our USA rubber molding capabilities.

    Why import tariffs and duties?

    • Protecting domestic employment – Political parties often raise the possibility of increased competition from imported goods that can threaten domestic industries to mobilize an electorate;
    • Protecting consumers – In some instance’s tariffs may be imposed to protect local consumers from sub-standard or hazardous products;
    • Infant industries – Governments, particularly in developing countries, may impose tariffs to shield infant and start-up industries from the external competition;
    • National security – Tariff barriers may be employed by governments to protect strategic economic sectors such as defence contractors or providers of information and communications technology;
    • Retaliation – Countries can set tariffs as retaliation for a perceived or real subversion of trading rules or solely for political purposes.

    Who pays for the import tariffs or duties?

    Ultimately domestic consumers in the importing country pay for the tariffs levied by their government on specific categories of imported goods or services.  The tariffs are not levied at the source of the import so they do not directly affect the exporting country. The net effect is, however, to make foreign products more expensive for consumers and may ultimately lead to reduced demand for such products or import substitution.  If manufacturers rely on imported components or other inputs in their production process that are subject to import tariffs, they will either have to pass on the increased cost to consumers or absorb this cost while reducing their profit margin.

    Types of tariffs and duties

    • Specific tariffs – the duty is calculated at fixed amount per unit that is imported;
    • Ad valorem tariffs – the tariff payable is based on a percentage of the value of the goods;
    • Licenses – importers must obtain costly licenses to import certain products. The cost of these licenses is passed on to the consumer, pushing up the cost and reducing demand. This ultimately leads to a reduction in business competitiveness;
    • Import quotas – quotas are set to limit the imported volumes of certain targeted items;
    • Voluntary export restraints – these are export limitations imposed by exporting countries in response to similar restraints set by trading partners to protect certain industries or sectors in each other’s countries;
    • Local content requirements – local content requirements are introduced to support to ensure that a portion of inputs for local production are locally sourced and not imported.

    Jefferson Rubber Works is an American owned and based company, primarily supplying customers within the United States of America. Our history of supplying high-quality rubber molded products stretches over more than 40 years. We’re proud that over 85% of our comprehensive range of products are manufactured locally in our modern production facility in Worcester, Massachusetts.

    All rubber molding formats consist of several steps. Each process is carefully analyzed for potential flaws that can lead to disruption of the production cycle or cause quality control challenges. These are then reviewed by management and line workers, and where deemed necessary, the process is changed and documented in the ISO manual as an upgraded standard.

    Process Flows

    Process flows provide a schematic view of how the processes interact and the sequences in which they are applied. These processes flows include both the physical aspects of production and the associated documentary records. Any deviation will result in investigations leading to a review and amended process flow in the ISO manual if necessary.


    ISO 9001 sets demands for the business to maintain extensive records about all its production and administrative processes. To maintain certification, the company must submit all its quality management system records for independent verification on an annual basis. The yearly audit reviews the control of documents and records, internal audits, control of nonconforming products, corrective actions, and preventative measures taken.

    Jefferson Rubber Works, having noted the advantages of ISO 9001:2015 certification, is currently exploring further ISO certification standards with regards to Environmental Management ISO 18001 and Occupational Health and Safety ISO 45001 (formally ISO 18001).
