About Karl Steel International Company Limited - Stainless Steel Coils Supplier in China

Karl Steel International Company Limited operates from China and currently lists six active stainless steel coil products. The catalogue covers martensitic, austenitic and half‑copper alloy coils, each identified by specific HS‑code families such as 7219.13 for SS 410 and 7219.31 for the 201 and 202 grades. The product set includes both cold‑rolled and hot‑rolled coils, with material designations that match international grade numbers (e.g., 304/316, 410, 201, 202). The supplier’s active product count of six reflects a focused range within the broader stainless‑steel coil segment.

The listed items comprise a “410 stainless steel coils” entry without an HS code, a “Stainless steel coil 201” (HS 7219.31, Austenitic 201), a “Stainless steel coil 202” (HS 7219.31, Austenitic Cr‑Mn‑Ni 202), an “SS 410” coil (HS 7219.13, Martensitic 410 with 11.5‑13.5 % Cr), a “Cold rolled stainless steel coil” (HS 7219.32, Grades 304/316) and a “Half Copper 201 Cold Rolled Stainless Steel Coil” (HS 7219.33, Austenitic 201 with half copper). These entries use standard industry nomenclature and HS‑code classifications for stainless‑steel sheet and strip products.

Product Range and Specialties of Karl Steel International Company Limited

The catalogue focuses on stainless‑steel coils in grades 201, 202, 304, 316, and 410, covering both austenitic and martensitic families. In global trade, coils of these grades are supplied in thicknesses from 0.3 mm to 5 mm, widths between 1000 mm and 2000 mm, and are commonly delivered in coiled form on wooden pallets. Typical specifications reference ASTM A240 / EN 10088 chemical limits, tensile strength ranges of 450‑620 MPa for 304/316 and 480‑720 MPa for 410, and surface finishes such as 2B or mill‑annealed. Buyers often request certification to ASTM, ISO 9001 and compliance with REACH for traceable alloy composition.

Trade and Export Information - Karl Steel International Company Limited

China is one of the world’s largest exporters of stainless‑steel coils, with the HS‑chapter 72 code family (7219) covering flat products of stainless steel. Major import destinations include the United States, the European Union, Southeast Asia and the Middle East, where the coils serve automotive bodies, construction, appliance manufacturing and oil‑field equipment. Export shipments are typically packed in steel‑wrapped bundles on 20‑ft or 40‑ft containers, with FOB Shanghai or CIF destination terms. Standard trade documentation includes a commercial invoice, packing list, bill of lading, and a mill test report that meets ASTM A240/EN 10088 requirements. Buyers frequently request third‑party inspection reports (e.g., SGS, Bureau Veritas) and certificates of compliance with REACH and RoHS for trace metals.

Sourcing from Karl Steel International Company Limited - Buyer Guidance

When sourcing stainless‑steel coils from this supplier, request a detailed mill test report that lists chemical composition, tensile strength, elongation and surface finish. Verify that the coil dimensions (thickness, width, length) match your project tolerances and that the material grade aligns with the required ASTM or EN standard. It is advisable to ask for ISO 9001 quality‑management certification and any third‑party inspection certificates to confirm conformity with REACH and other environmental regulations. Samples of a representative coil batch can be requested to assess surface quality and mechanical performance before confirming a larger order.

What stainless‑steel grades does Karl Steel International list in its catalogue?

The catalogue includes coils of grades 201, 202, 304, 316, and 410, covering both austenitic and martensitic stainless‑steel families.

Which HS codes are associated with the listed coils?

The HS codes are 7219.31 for grades 201 and 202, 7219.13 for grade 410, 7219.32 for the cold‑rolled 304/316 coil, and 7219.33 for the half‑copper 201 coil. One entry (“410 stainless steel coils”) does not specify an HS code.

What typical specifications should a buyer verify for these coils?

Buyers should confirm chemical composition limits per ASTM A240/EN 10088, tensile strength (e.g., 450‑620 MPa for 304/316, 480‑720 MPa for 410), thickness, width, surface finish (2B or mill‑annealed) and any required certifications.

What documentation is normally required before placing an order?

A mill test report, ISO 9001 quality‑management certificate, REACH compliance statement and, when needed, a third‑party inspection report (SGS, BV) are standard documents.

How are the coils typically packaged for export?

Coils are usually bundled, wrapped in protective steel or plastic film, stacked on wooden pallets and loaded into 20‑ft or 40‑ft containers under FOB Shanghai or CIF terms.

What are common lead times for stainless‑steel coil shipments from China?

Lead times generally range from 4 to 8 weeks, depending on production scheduling, coil thickness, and the need for additional testing or certification documentation.

Which markets most frequently import stainless‑steel coils from China?

Key import markets are the United States, the European Union, Southeast Asian countries and the Middle East, where the coils are used in automotive, construction, appliance and oil‑field sectors.

Can I request a sample coil before a full order?

Yes, the supplier can provide a sample coil of the same grade and thickness for quality assessment, subject to standard sampling procedures and shipping arrangements.
