ire, Inner Tube and Flap Supply Chain Under Pressure: Qingdao Florescence Adjusts Prices Effective September 15
QINGDAO, China — September 20, 2026 — Tire, inner tube and flap manufacturers worldwide are absorbing a simultaneous surge in the cost of their three most important raw materials: carbon black, crude-oil-derived chemicals and natural rubber. The pressure has travelled through the supply chain with unusual speed, and QINGDAO FLORESCENCE CO., LTD has adjusted its selling prices effective September 15, 2026.
Carbon Black: +RMB 5,800 per Ton
On September 15, 2026, Cabot issued a price increase notice, raising specialty carbon black by RMB 5,800 per ton. Carbon black is the key reinforcing material in tire, inner tube and flap production, and its price has been climbing steadily in recent weeks.
The trigger lies upstream in coking coal. Mines in major producing regions have been affected by the combined impact of safety production inspections and environmental supervision, and the resumption of halted mines has fallen short of expectations. With the supply gap for high-quality coking coal continuing to widen, the cost pressure is being transmitted down the industrial chain step by step.
Crude Oil: Brent Breaks the $100 Mark
Brent crude continues its upward trend, breaking through the $100 level. Geopolitical tensions and tightening oil supply have supported firmer prices and pushed up the cost of oil-based inputs. Crude oil is the feedstock for a wide range of chemical products and downstream tire, inner tube and flap materials, so higher crude prices raise raw material costs for the manufacturing sector — including tire, inner tube and flap production.
Natural Rubber: A Five-Year High
On September 8, 2026, the main natural rubber contract price reached RMB 19,810 per ton, after climbing steadily since early August and ending the earlier low-price range.
Rubber is the single most important raw material in a tire, inner tube or flap, and every round of price increases is transmitted directly into tire, inner tube and flap production costs. At around RMB 19,000 per ton, the current price level represents a five-year high and adds a further layer of cost for every tire, inner tube and flap manufacturer.
Qingdao Florescence Adjusts Prices
QINGDAO FLORESCENCE CO., LTD, a manufacturer of tire, inner tube and flap products, has adjusted its prices effective September 15, 2026 in response to the sustained increases in carbon black, crude oil and natural rubber costs.
The adjustment reflects raw material cost movements only. Despite the pressure, the company has worked to keep the increase as moderate as possible and continues to hold its quality and service standards unchanged.
What This Means for Buyers
With all three major raw materials rising at the same time, further cost volatility across the tire, inner tube and flap supply chain is likely in the weeks ahead. Buyers are encouraged to confirm quotations and plan orders early, and to lock in pricing for confirmed volumes wherever possible.
