The Eurasian Duty on Chinese Oil Pipes Runs 12.23% to 31% — and One List Decides Which

AI Summary

The Eurasian Economic Commission extended its anti-dumping duty on Chinese seamless oil well pipe for five years on 6 October 2026, keeping the rates it set in 2015: 12.23% to 31.00% of CIF value. One decision in the same announcement matters more to a buyer than the rates — Hunting Energy Services (Wuxi) lost its place on the price undertaking list, which is the mechanism that lets an exporter sell without the duty at all.

What happened

The Eurasian Economic Commission’s Internal Market Protection Department published announcement 2026/520/AD16R2 on 9 October 2026, acting under Board Decision No. 127 of 6 October 2026. It maintains Decision No. 101 of 2015 unchanged: an anti-dumping duty on seamless steel pipes used for drilling and operating oil and gas wells, originating in China, at 12.23% to 31.00% of CIF value.

The rates are ten years old. They were set in the original determination of 18 August 2015, kept through the first sunset review that ran the measure to 26 April 2026, and kept again now. A buyer reading only the headline learns that nothing changed, which is the wrong conclusion: the rate spread is what decides the invoice, and one list changed.

Price undertaking — a commitment by an exporter to sell at or above a minimum price, accepted by the investigating authority in place of the duty. An exporter on the list sells without the anti-dumping duty being collected. An exporter off the list attracts the full rate, and the buyer pays it. It is the single most valuable question to ask a pipe supplier in this market, and it is answered by a list rather than by a negotiation.

Why now

This is the third time the measure has come up for renewal, and the pattern of the three is the useful part.

The original investigation opened on 31 March 2014. The determination followed on 18 August 2015 and imposed the duty at these rates. The first sunset review opened on 13 May 2020, and the extension took effect on 29 April 2021, running to 26 April 2026. The second sunset review opened on 22 December 2025, covering a dumping investigation period of July 2024 to June 2025. Final disclosure came on 20 July 2026, and the decision on 6 October 2026.

Twelve years, three reviews, one rate. The application that triggered this review came from six EAEU producers — Chelyabinsk Pipe Rolling Plant, Pervouralsk New Pipe Plant, Volzhsky Pipe Plant, Seversky Pipe Plant, Taganrog Metallurgical Plant and Sinarsky Pipe Plant — which is the ordinary mechanics of a sunset review and also the reason to expect a fourth: the domestic industry has asked twice and been granted twice.

The Belt-and-Road point is structural rather than incidental. The EAEU is five member states with a single external tariff, and for a Chinese pipe exporter it is one of the few large markets that is neither the United States nor the European Union. Until this article, this site had priced measures in North America, Europe and ASEAN but not in Eurasia, and the corridor running from Chinese mills to Kazakh, Russian and Belarusian oilfields is exactly the kind of route the customer definition names.

So what

The duty is charged on CIF value, so the same physical pipe carries a different duty depending on who made it. That is the whole decision, and it happens before a purchase order exists.

The spread is 2.535 times the lowest rate. Put differently: choosing a supplier at the top of the range costs 2.5 times the duty of choosing one at the bottom, on identical goods, at identical prices. No negotiation recovers $93,850 on half a million dollars of pipe; changing the mill does.

The undertaking list cuts deeper than the range. An exporter on it sells without the duty, so the gap between a listed exporter and an unlisted one is not 18.77 points but the full rate — up to $155,000 on the same order. Hunting Energy Services (Wuxi) was on that list and is not any more, by this decision. A buyer who contracted with that entity on the assumption that no duty was payable is now exposed to the full rate on shipments arriving after the measure takes effect.

How confident

Confirmed. The announcement number, its date, the decision it rests on, the maintained rate range of 12.23% to 31.00%, the five-year term ending 5 October 2031, the removal of Hunting Energy Services (Wuxi) from the undertaking list, and the covered tariff headings are read from the Commission’s own announcement as recorded by the China Trade Remedy Information Network. The decision and its date are independently confirmed by Rossiyskaya Gazeta, the Russian government’s newspaper of record, which also names the six EAEU producers that applied. Interfax, reporting in English on 9 October 2026, independently confirms the five-year extension, the product, the 12.23 rate and the existence of the undertaking list.

Inferred. The per-order dollar figures are my arithmetic on a CIF value I chose. $500,000 is an illustration, not a market observation, and a reader’s own order value replaces it directly — the percentages are the published part and the dollars follow from the value. I have taken the duty as applying to the CIF value as entered, which is the ordinary basis for an ad valorem anti-dumping duty and is not restated in the text of the announcement I was able to read. I have also read “30 days after publication” as running from the publication date of 9 October 2026, which puts the measure in force around 8 November 2026; the announcement states the interval rather than a calendar date, and the operative date is the one customs will apply.

What would change my mind. If the price undertaking list contains entities beyond those named in the summary I read, then the practical choice for a buyer is wider than this article implies — the announcement lists the removals, and I did not obtain the full current list, so a company that appears absent here is not thereby off it. If the Commission applies the duty to a value other than the declared CIF, every dollar figure above moves. And if the measure is challenged or suspended before it takes effect at the end of the 30-day interval, the operative date changes while the rates do not.

For you

• Buyers of oil country tubular goods into Russia, Kazakhstan, Belarus, Armenia or Kyrgyzstan: ask the mill for its undertaking status in writing before the order, not at the port. The question is whether the specific exporting legal entity is on the list, because the list names entities and the removal this month named one.
• Anyone who has been buying from Hunting Energy Services (Wuxi): the duty now attaches where it did not. Model the full rate against your landed cost on shipments that arrive after the measure takes effect, and start the alternative-supplier conversation now rather than when the goods are afloat.
• If you are choosing between two mills at the same price: the duty spread is 2.535 times, so the cheaper-looking quotation is not the cheaper landed cost until the rate is attached to it. Ask for the rate alongside the price.
• Exporters and their agents: the ten-year stability of these rates is itself the argument to make to a customer. Twelve years and three reviews produced one range and one set of names, which is long enough to plan a contract around. Where freight is a separate line, the same discipline applies to the index mechanism — see the two errors in linking a contract to a freight index before you tie a duty-inclusive price to one.
• Anyone tracking the corridor: a fourth sunset review is the base case given the domestic industry has applied twice and succeeded twice. The pertinent date is now 5 October 2031, and the pertinent question each time is who is on the undertaking list, not what the rate is.

The data point

FAQ

Does the duty apply to the pipe or to the company that made it?

To the pipe, at a rate that depends on the exporter. The measure is an anti-dumping duty on seamless steel pipe for oil and gas wells originating in China, and the rate applied is the one determined for the exporting producer concerned, between 12.23% and 31.00%. That is why the supplier’s identity is a cost input rather than a commercial detail: two mills quoting the same price per tonne deliver different landed costs by up to 18.77 percentage points. The duty attaches at import, on CIF value.

What is a price undertaking and why does losing it matter?

An undertaking is an exporter’s commitment to sell at or above a minimum price, accepted by the investigating authority in place of the duty. While it is in force, the duty is not collected on that exporter’s shipments. Removing a company from the list means the undertaking no longer covers it, so its goods attract the full rate. For a buyer, the practical difference between a listed and an unlisted supplier is the entire duty, not a portion of it.

When does this take effect?

The announcement was published on 9 October 2026 and the measure takes effect 30 days later, which places it in force around 8 November 2026, running to 5 October 2031 inclusive. Shipments arriving after that date carry the duty. Goods in transit and contracts already signed are the obvious questions, and the answer depends on the entry date rather than the contract date, which is why the interval between publication and effect is the window in which existing arrangements can still be adjusted.

Is this the same as the European Union steel measures?

It uses the same instrument in a different jurisdiction. The European Union runs anti-dumping and countervailing measures on Chinese steel under its own regulations, and the per-tonne cost of those has to be modelled separately because the bases differ — the EU’s carbon border adjustment sits alongside its safeguard, while this EAEU measure is a straightforward ad valorem duty on CIF. A seller shipping to both markets carries both, and neither offsets the other.

Why are the rates unchanged after twelve years?

Because a sunset review asks whether the injury would recur, not whether the margin should be recalculated. The Commission examined a dumping period of July 2024 to June 2025 and concluded the measure should continue, which it can do at the existing rates. That is why the useful information in a renewal is rarely the rate: it is what else the decision does, and in this one that was the undertaking list.

How we calculated this

The duty is ad valorem, so it is a percentage of the CIF value the importer declares. The order value is an input, and the arithmetic is:

duty on an order = CIF value x rate

lowest rate    $500,000 x 12.23% = $61,150
midpoint       $500,000 x 21.62% = $108,100   (midpoint shown for reference only)
highest rate   $500,000 x 31.00% = $155,000

spread = $155,000 - $61,150 = $93,850
       = 18.77 percentage points

ratio  = 31.00 / 12.23 = 2.535

per tonne, on a $1,200 per tonne CIF price:
  12.23% = $146.76 per tonne
  31.00% = $372.00 per tonne

Replace the CIF value with your own invoice value and the rate with the one your supplier attracts. The percentage is the published fact; the dollars follow from your order.

The point

A ten-year-old rate range that did not change is not the story, and reading the headline as “nothing changed” is the mistake available to anyone who stops there. The measure covers a spread of 2.535 times, decided by which mill produced the pipe, and the same decision quietly moved one exporter off the list that removes the duty entirely.

For an importer, the question is not what the duty is. It is which rate your supplier attracts, whether that supplier still holds an undertaking, and what the answer does to your landed cost before the order is placed. Ask it in writing, and ask it about the exporting entity rather than the brand.
