September 28, 2026 – A Time-Sensitive Update from Sanonpipe
This is not the usual market commentary. It is a practical, time-sensitive notice for buyers of seamless steel pipe, welded steel pipe, and structural hollow sections who are planning shipments into the fourth quarter of 2026. With China's National Day holiday approaching, the window for pre-holiday production and shipment is closing fast.
The Immediate Issue: A Seven-Day Pause Is About to Hit the Supply Chain
China will observe the National Day holiday from October 1 to 7, 2026. For the steel pipe industry, the impact is not limited to those seven days.
What actually happens:
Mills in most regions stop production or run at reduced capacity during the holiday week.
Logistics and port operations slow significantly, with limited vessel bookings and customs processing.
Workers return gradually after the holiday, meaning most mills do not reach full output until roughly October 10 to 12.
In practical terms, buyers lose about two working weeks. Any order for API 5L line pipe, ASTM A106 seamless pipe, ASTM A335 alloy boiler tubes, or EN 10219 hollow sections that is not confirmed before the end of September will almost certainly slip into mid-to-late October production.
What This Means Right Now for Buyers
| Your Situation | Practical Consequence |
| You need material delivered in November | Orders must be confirmed this week, or you risk delay into December. |
| You need material delivered in December | Still workable, but production slots are filling fast, especially for alloy steel pipe and large-diameter seamless pipe. |
| You are still comparing prices | Delivery timing is now a bigger variable than price. The cheapest offer may not be the one that ships first. |
| You are planning for Q1 2027 | This is actually the ideal time to place orders, ahead of the post-holiday rush. |
International Situation: Quiet but Not Settled
The global backdrop remains a factor, though it is no longer the dominant story it was earlier in the year.
Middle East shipping lanes: The Strait of Hormuz remains monitored but stable. Risk premiums and routing adjustments are now built into freight quotations rather than being separate surcharges.
Europe compliance environment: Carbon documentation requirements for carbon steel pipe, alloy steel pipe, and stainless steel seamless pipe continue to tighten. Buyers are advised to request sample documentation before confirming orders, not after.
Energy prices: Oil remains range-bound, offering some stability to production costs but no significant relief.
Q4 2026 Market Outlook: Three Realistic Scenarios
Rather than a single forecast, here are three scenarios buyers should prepare for.
| Scenario | Likely Conditions | What Buyers Should Do |
| Base case: Stable with friction | Prices steady, lead times 30–50 days, freight high but predictable. | Confirm orders before the holiday. Lock production slots for API 5L X60/X65, ASTM A106 Grade B, and ASTM A335 P11/P22. |
| Tight case: Alloy and specialty squeeze | Longer lead times for ASTM A335 P91, ASTM A213 T91, and ASTM A790 duplex grades. | Order early for high-specification materials. Accept that price negotiation room is limited. |
| Disruption case: Logistics or compliance delay | Port congestion or documentation issues push deliveries back by 2–3 weeks. | Ensure carbon footprint files, green power certificates, and scrap ratio records are ready before shipment. |
Material Focus: What to Prioritise Before the Holiday
| Material Grade / Standard | Key Application | Pre-Holiday Priority |
| API 5L X52 / X60 / X65 | Oil and gas transmission pipelines | High. Demand is steady and production slots are competitive. |
| API 5L X70 | High-pressure long-distance pipelines | Medium-high. Fewer mills, longer lead times. |
| ASTM A106 Grade B/C | High-temperature service, boilers, refineries | High. Widely used but volume is large. |
| ASTM A335 P11 / P22 / P91 | Power generation, superheaters, reheaters | High for P91, steady for P11/P22. Heat treatment capacity is limited. |
| ASTM A213 T11 / T22 / T91 | Boiler tubes and heat exchangers | Steady. Often overlooked until maintenance season. |
| ASTM A312 TP304 / TP304L | Chemical, food, and process industries | Moderate. TP304L preferred for welding. |
| ASTM A312 TP316 / TP316L | Marine, chemical, high-corrosion environments | Growing. TP316L increasingly specified as default. |
| ASTM A333 Grade 6 | LNG and low-temperature service | Niche but critical. Limited supplier pool. |
| ASTM A790 Duplex 2205 | Offshore and chemical processing | Growing. Long lead times, plan well ahead. |
| EN 10210-1 S355J2H | Hot-finished structural frameworks | High for European projects. Documentation is strict. |
| EN 10219-1 S355J2H | Cold-formed structures and scaffolding | Stable. Widely available but quality varies by mill. |
| NACE MR0175 Sour Service | H2S-resistant oil and gas applications | Mandatory for harsh environments. Certified mills only. |
| Precision Seamless Tubes | Hydraulic cylinders and automotive components | Moderate. HSLA grades gaining interest. |
Currency and Freight: A Quick Practical Note
USD/CNY: The yuan remains relatively weak against the dollar, which slightly favours buyers settling in USD.
EUR/CNY: The effect is smaller for euro-based buyers, but still worth factoring into contract timing.
Sea freight: Rates remain elevated but no longer spiking. The bigger risk now is schedule reliability, not price.
Incoterms: With freight and compliance costs rising, the choice between FOB and CIF has a larger impact on total cost than in previous years.
Action Checklist Before September Ends
Confirm any November delivery orders this week.
Request sample carbon documentation for European-bound shipments.
Lock production slots for high-specification grades such as ASTM A335 P91 and ASTM A790 duplex.
Decide currency and Incoterm before negotiations conclude.
Ask your supplier directly: what happens to my order during the holiday?
Closing Note
The National Day holiday is a predictable event, but its impact on delivery schedules is often underestimated. Buyers who act this week will avoid the delays that catch others off guard in November.
