US anti-dumping duties on Chinese oil-country tubular goods confirmed
The US International Trade Commission (ITC) has issued final determinations on anti-dumping duties on oil-country tubular goods (OCTG) from China, following a review of existing trade remedy orders. The ruling maintains duties on Chinese OCTG imports, affecting manufacturers and importers of steel pipes and tubes used in oil and gas drilling operations. Importers must ensure duty payments are calculated correctly and that origin marking complies with US customs requirements.

On 19 May 2026, the US International Trade Commission published final determinations in an anti-dumping investigation into oil-country tubular goods (OCTG) from China, as announced in the Federal Register.
What OCTG covers
Oil-country tubular goods—steel pipes, casings, and tubing used in oil and gas well drilling, extraction, and production—fall primarily under HS chapter 73 (iron and steel products). The anti-dumping order applies to seamless and welded OCTG imported from China, whether finished or in semi-finished form.
Who is affected
The determination impacts:
- Importers and distributors of OCTG from China into the United States
- Domestic US OCTG manufacturers competing with Chinese suppliers
- Oil and gas operators who purchase OCTG-containing equipment or services
Importers must pay anti-dumping duties on all covered merchandise. The ITC's affirmative determinations mean the duties remain in place and are enforceable at US ports of entry.
Duty implications
Anti-dumping duties are assessed as a percentage of entered value and vary by exporter. Importers are responsible for:
- Declaring the correct country of origin (China) on entry documents
- Ensuring proper HS classification (typically 73.04.41, 73.04.49, or 73.05.19 depending on pipe type and finish)
- Paying estimated duties at entry; final assessments are reconciled after ITC annual reviews
- Maintaining cost and pricing records to support landed-cost estimates
The ITC determinations are based on evidence of price undercutting and material injury to the US OCTG industry, and confirm that Chinese producers continue to dump OCTG into the US market at less than fair value.
What this means for shippers
If you import OCTG from China, verify HS classification immediately—misclassification can trigger penalties on top of anti-dumping duty. Update your landed-cost models to include current anti-dumping rates by exporter; rates are published by US Customs and Border Protection (CBP) and change annually. Document supplier invoices and origin certificates to prove China sourcing and calculate duties accurately. File cost entries and reconciliation statements on schedule or face duty shortfall assessments and interest charges. Use our tariff lookup to confirm duty rates and model landed cost.
