Additional entries are ASTM A519 honed seamless tube (HS code 7304.31) using 4130/4140 alloy steel, ASTM A333 low‑temperature seamless pipe (HS code 7304.31) of carbon low‑temperature grade, and a JIS G3445 carbon steel mechanical tubing entry without a listed HS code.

The supplier’s catalogue spans the top categories of Steel Tubes, Steel, Steel Pipes and Agriculture, although the listed items focus on seamless tubing and structural steel products. HS code 7304.31 is the standard tariff heading for seamless cold‑drawn steel tubes, while HS code 7306.30 covers structural steel shapes and bars. Materials range from plain carbon steel to low‑alloy alloy grades, reflecting typical specifications demanded by automotive, construction and machinery sectors.

Product Range and Specialties of Shaanxi Shew-E steel pipe Co.,Ltd

The product range includes DIN 2391‑1 tubes supplied in carbon steel grades ST52.4 (E355) and ST37.4 (E235), which are commonly delivered with tolerance of ±0.2 mm and surface roughness Ra ≤ 0.8 µm. EN 10210‑1 structural steels listed cover non‑alloy grades S235JR, S275JR and high‑strength S355J2H, typically offered in hot‑rolled sections with yield strength 235 - 355 MPa. ASTM A519 tubes are made from 4130/4140 alloy steel, a grade frequently required for high‑strength automotive components, and ASTM A333 pipes meet low‑temperature specifications down to - 50 °C for oil‑field and cryogenic applications. JIS G3445 mechanical tubing, while not assigned an HS code in the data, generally follows Japanese standards for carbon steel dimensions and tensile properties.

Industry practice for these categories includes offering wall thicknesses from 1.5 mm to 20 mm, diameters from 6 mm to 300 mm, and providing mill test certificates (MTC) that confirm chemical composition and mechanical performance. Buyers often request compliance with DIN, EN, ASTM or JIS standards, along with optional CE marking for EU markets. Typical packaging involves wooden crates with internal padding, and bulk shipments fill 20‑ft or 40‑ft containers depending on tube length.

Trade and Export Information - Shaanxi Shew-E steel pipe Co.,Ltd

China remains one of the world’s largest exporters of seamless steel tubes and structural steels, supplying Europe, the Middle East, Southeast Asia and North America. HS code 7304.31 products are subject to customs inspections that verify conformity with the declared standards (DIN, EN, ASTM) and may require an SGS or Bureau Veritas pre‑shipment inspection for high‑value orders. Common certifications requested by importers include ISO 9001 quality management, CE marking for EU entry, and compliance with ASTM or EN specifications depending on the destination market.

Logistically, these steel products are typically shipped FOB Shanghai or Tianjin, with buyers arranging container loading on 20‑ft (≈ 22 tons) or 40‑ft (≈ 44 tons) units. Because the items are heavy and prone to corrosion, they are often coated with a light oil film and packed in moisture‑controlled crates. Import regulations in the EU and US frequently mandate a Material Safety Data Sheet (MSDS) and a declaration of compliance with REACH or the US Toxic Substances Control Act for alloyed steels.

Sourcing from Shaanxi Shew-E steel pipe Co.,Ltd - Buyer Guidance

When sourcing from Shaanxi Shew‑E, buyers should request the latest mill test certificate that details chemical analysis, tensile strength, elongation and impact values for each grade. For ASTM A519 and A333 items, a heat‑treatment report confirming quench and temper parameters is standard practice. Verification of ISO 9001 certification and, if required, CE conformity assessment should be obtained before finalizing the order.

Samples of the tube dimensions, surface finish and mechanical properties are typically provided on a small‑scale basis; buyers should specify the required length, diameter and wall thickness to ensure the sample matches the production spec. Confirm packaging details - whether the shipment will be in wooden crates, palletized bundles or bulk containers - and clarify Incoterms (FOB, CIF) to align responsibilities for freight and insurance.

What standards do the listed steel tubes comply with?

The DIN 2391‑1 tube follows German DIN standards, EN 10210‑1 structural steel complies with European EN specifications, and the ASTM A519 and A333 items meet the corresponding American ASTM standards. JIS G3445 tubing adheres to Japanese Industrial Standards.

Which HS codes are associated with the products?

Seamless steel tubes and pipes are classified under HS code 7304.31, while the EN 10210‑1 structural steel shapes use HS code 7306.30. The JIS G3445 entry does not have an HS code listed in the catalogue.

What material grades are available for the seamless tubes?

Grades include carbon steel ST52.4 (E355) or ST37.4 (E235) for DIN 2391‑1, carbon steel E235/E355 for EN 10305‑1, and alloy steel 4130/4140 for ASTM A519. Low‑temperature carbon steel is supplied for ASTM A333 pipes.

What documentation should I request before purchase?

Ask for the mill test certificate, heat‑treatment report (for alloyed grades), ISO 9001 certification, and, if shipping to the EU, a CE declaration of conformity. An SGS pre‑shipment inspection report adds an extra layer of verification.

What are typical packaging and shipping methods?

Products are usually packed in moisture‑controlled wooden crates with internal padding, loaded into 20‑ft or 40‑ft containers. Common Incoterms are FOB Shanghai or Tianjin, with buyers arranging freight forwarding.

Which markets commonly import these steel products?

Major importers include automotive manufacturers in Europe, construction firms in the Middle East, oil‑field equipment suppliers in Southeast Asia, and machinery producers in North America. These regions frequently require compliance with EN, ASTM or DIN standards.

Is there a minimum order quantity (MOQ) for the tubes?

MOQ varies by grade and dimensions, but suppliers typically require a minimum of one standard 6 m length per size, which translates to roughly 2‑3 tons per order for common diameters.

What lead time can I expect for a new order?

Standard lead times range from 30 to 45 days after order confirmation, depending on the grade, size and any required heat‑treatment or certification documentation.
