Logistics and transportation costs:
- Transportation distance: The distance between the production site and the sales market will affect transportation costs, and long-distance transportation will increase logistics costs.
- Transportation mode: Different modes of transportation (such as sea, air, and land transportation) have different costs, which will also affect costs.
Certification and compliance costs:
- International certification: The cost of obtaining international certification and meeting national standards. These certifications are essential for entering the international market, but they will increase costs.
- Regulatory compliance: Environmental regulations and quality standards vary from country to country, and compliance with these regulations may require additional costs.
R&D and innovation investment:
- New technology research and development: Continuous R&D investment and technological innovation can lead to more efficient products, but will increase costs in the short term.
