The International Oil Prices Have Risen. Which Parts Of The Cost in The Hot Water Bag Industry Will Increase?

The increase in oil prices will raise the costs of the hot water bag industry in four major areas: raw materials, production energy consumption, logistics, and packaging. Among these, plastic/rubber-based raw materials have the most direct and significant impact.
Ⅰ. Core raw material costs (the most sensitive)
- PVC (accounting for approximately 28% of the total cost): The mainstream material for hot water bags, the raw material ethylene/vinyl chloride comes from petroleum; an increase in oil prices leads to a simultaneous rise in PVC resin and plasticizers (DOP/DINP), directly raising the main cost.
- Synthetic rubber (styrene-butadiene/isonitrile-butadiene): Raw materials for inner casings and seals, 100% derived from petroleum; an increase in oil prices leads to an increase in synthetic rubber prices, squeezing the profit of rubber hot water bags.
- TPE/silicone/PP: Environmental-friendly alternative materials, all based on petroleum; an increase in oil prices leads to a simultaneous increase in the cost of these alternative materials.
- Plasticizers/auxiliary agents: Essential for PVC, completely dependent on petrochemicals; an increase in oil prices leads to an increase in the prices of auxiliaries, causing a rise in the individual cost.
II. Energy Consumption Costs in Production and Manufacturing
The processes such as injection molding, blow molding, vulcanization, and drying consume electricity and gas; as oil prices rise, the costs of electricity and natural gas increase, leading to a rise in energy consumption expenses for factories.
III. Logistics Transportation Costs
- Land or sea transportation for raw material procurement and finished product delivery: Increase in diesel/fuel prices → Rise in transportation costs, accounting for 3% - 8% of the total cost.
- Cross-regional supply chain (such as importing rubber/plastic particles): Rise in shipping costs further drives up the arrival price.
IV. Packaging Material Costs
- PET/PE plastic bags, heat shrink films, and foam: All are petroleum-based; rising oil prices → increase in packaging costs (accounting for approximately 5% of the total cost).
V. Additional Costs of Electric Hot Water Bags
- Power cord, plug, plastic casing (PP/ABS): Derived from petroleum, prices have risen simultaneously.
- Energy consumption in production processes such as injection molding, welding, and aging tests has increased.
Summary of Cost Transmission
- Raw materials (PVC + synthetic glue + additives): account for 55% - 65% of the total cost. A 10% increase in oil prices leads to a reduction of approximately 2 - 3 percentage points in the industry's gross profit margin.
- Logistics + packaging + energy consumption: together account for 10% - 15%. A 10% increase in oil prices results in an overall increase of 3% - 5%.
- Small and medium-sized enterprises are under greater pressure: lacking the advantage of large-scale procurement, the cost increase can reach 12% or more.
