Independent third parties manufacture all of our products for us. As a result, we are directly impacted by increases in the cost of those products.
If we experience significant increases in demand or need to replace an existing vendor, there can be no assurance that additional manufacturing capacity will be available when required on terms that are acceptable to us or that any vendor would allocate sufficient capacity to us to meet our requirements. In addition, for any new manufacturing source, we may encounter delays in production and added costs as a result of the time it takes to train our vendors in our methods and products, as well as our quality control, environmental, labor, health, and safety standards. Moreover, in the event of a significant disruption in the supply of the fabrics or raw materials used by our vendors in the manufacture of our products, our vendors might not be able to locate alternative suppliers of materials of comparable quality at an acceptable price. Any delays, interruptions, or increased costs in the manufacture of our products could impact our ability to source product and result in lower than anticipated sales.
A large portion of our global sourcing comes from a few specific countries. For example, in fiscal 2023, approximately 29 percent and 18 percent of our merchandise, by dollar value, was purchased from factories in Vietnam and Indonesia, respectively. Delays in production and added costs in these countries have in the past and may in the future adversely affect our results of operations.
Because independent vendors manufacture virtually all of our products outside of our principal sales markets, third parties must transport our products over large geographic distances. Increases in transportation costs or delays in the shipment or delivery of our products due to the availability of transportation, work stoppages, port strikes, port and infrastructure congestion, public health crises, social unrest, changes in local economic conditions, political upheavals, or other factors, and costs and delays associated with transitioning between vendors, could adversely affect our results of operations. Attacks on cargo ships in the Red Sea, catalyzed by the Israel-Hamas conflict, have disrupted Red Sea shipping lanes and may continue to disrupt global trade flows and impact shipping capacity. Operating or manufacturing delays, transportation delays, or unexpected demand for our products may require us to use faster, but more expensive, transportation methods such as air freight, which have in the past and may in the future adversely affect our gross margins. In addition, the cost of fuel is a significant component of transportation costs, so increases in the price of petroleum products (including due to inflationary pressures, geopolitical instability, or regulation of energy inputs and greenhouse gas emissions) could adversely affect our gross margins.
If our vendors, or any raw material suppliers on which our vendors rely, suffer prolonged manufacturing or transportation disruptions due to pandemics and public health crises, extreme weather conditions and natural disasters, geopolitical instability, or other unforeseen events, our ability to source product could be adversely impacted which would adversely affect our sales and results of operations.
