China‑based Hebei Smart Steel Pipe Mill Co., Ltd lists seven active products. The catalogue covers steel pipe products such as seamless steel pipe, API 5L Grade B steel pipe, carbon seamless steel pipe (HS 7304.11, carbon steel API 5L Grade B / ASTM A106 Grade B), seamless steel pipe to ASTM A106 (HS 7304.31, carbon steel ASTM A106 Grade B with typical chemical limits of C ≤0.30 %, Mn 0.29‑1.06 %, S+P ≤0.035 %), DIN‑standard seamless steel pipe (HS 7304.31, carbon steel ST35.8, ST45.8, ST52.3 per DIN 17175/1629), and seamless steel pipe to ASTM A53 Grade B. The remaining entries are generic “seamless steel pipe” and “seamless steel pipe (ASTM A53 Gr B)” without HS codes in the supplied data.

Product Range and Specialties of Hebei Smart Steel Pipe Mill Co., Ltd

The catalogue includes seamless carbon steel pipes that meet API 5L Grade B, ASTM A106 Grade B, ASTM A53 Grade B and DIN ST35.8/ST45.8/ST52.3 specifications. In the industry, API 5L Grade B pipes are commonly supplied in NPS 4‑24 with wall thicknesses ranging from 2.77 mm to 12.70 mm, pressure ratings up to 2.9 MPa, and compliance with API 5L and ISO 3183. ASTM A106 and A53 Grade B pipes are typically produced in sizes NPS ½‑24, with carbon content ≤0.30 % and tensile strength 415‑690 MPa, and are inspected under ASTM A106/A53 standards. DIN‑specified pipes follow DIN 17175/1629, with mechanical properties defined by the respective steel grades. Buyers usually request mill test reports, chemical analysis, dimensional tolerance (±0.5 mm), and surface condition (free of defects). Standard export packaging for seamless steel pipes from China involves bundling lengths of 6 m or 12 m, placed on wooden pallets, and loaded into 20‑ft or 40‑ft containers with a typical net weight of 18‑22 tonnes per container. Thickness, diameter and length are recorded on the shipping document and matched to the HS sub‑heading for customs clearance.

Trade and Export Information - Hebei Smart Steel Pipe Mill Co., Ltd

China is one of the world’s largest exporters of seamless steel pipe, with the majority of shipments destined for the Middle East, Africa, South‑East Asia and Europe. The HS codes 7304.11 and 7304.31 are subject to standard customs duties and may require a certificate of origin, commercial invoice and packing list. Importing countries often demand compliance with ISO 9001 quality management, API product certification, and, where applicable, CE marking for European markets.

Typical Incoterms used by Chinese pipe exporters are FOB Tianjin or Dalian, with buyers arranging inland transport. Inspection agencies such as SGS, Bureau Veritas or Intertek are frequently engaged for pre‑shipment verification, including visual inspection, dimensional checks and hydrostatic pressure testing according to API 5L or ASTM standards. Container loading follows the container weight limits of 21 tonnes for 20‑ft and 26 tonnes for 40‑ft containers, and the pipes are often protected with anti‑rust coating or oil‑based preservative.

Sourcing from Hebei Smart Steel Pipe Mill Co., Ltd - Buyer Guidance

When sourcing from Hebei Smart Steel Pipe Mill Co., Ltd, buyers should request the specific mill test report (MTR) that details chemical composition, mechanical properties and heat‑treatment records for the listed standards (API 5L, ASTM A106, ASTM A53, DIN). Verify that the HS code on the commercial invoice matches the product specification (7304.11 for carbon steel pipes, 7304.31 for other seamless pipes).

Buyers are advised to confirm the product dimensions (outside diameter, wall thickness, length) and tolerances, request a third‑party inspection certificate, and clarify the packaging format (bundles, pallets, container size). Typical minimum order quantities range from one 20‑ft container (≈18 tonnes) to larger volumes, with lead times of 30‑45 days after order confirmation, depending on the grade and size.

What steel pipe standards are available in the catalogue?

The catalogue lists seamless pipes to API 5L Grade B, ASTM A106 Grade B, ASTM A53 Grade B and DIN ST35.8, ST45.8 and ST52.3 specifications.

Which HS codes correspond to the listed pipe products?

Carbon seamless steel pipe is under HS 7304.11, while the ASTM A106, DIN and other seamless pipe variants are classified under HS 7304.31.

What documentation should a buyer request before purchase?

Buyers should request a mill test report, a certificate of origin, and, if required by the destination market, third‑party inspection certificates such as SGS or Bureau Veritas reports.

What are typical packaging and container loading practices?

Pipes are usually bundled in 6 m or 12 m lengths, placed on wooden pallets, and loaded into 20‑ft or 40‑ft containers with a net weight of approximately 18‑22 tonnes per container.

Which certifications are commonly required for these steel pipes?

Importers often require ISO 9001 quality‑management certification, API product certification, and, for European buyers, CE marking where applicable.

What are the usual lead times and minimum order quantities?

Lead time is typically 30‑45 days after order confirmation, and the minimum order is generally one 20‑ft container (about 18 tonnes), although larger orders are accepted.

How are the pipes inspected before shipment?

Pre‑shipment inspection generally includes visual checks, dimensional verification, and hydrostatic pressure testing according to the relevant API or ASTM standard, performed by an accredited inspection agency.
