About T.F.T. International New Material Engineering Co., Ltd. - Tungsten Products Supplier in Hong Kong

Hong Kong‑based T.F.T. International New Material Engineering Co., Ltd. lists six active products in its catalogue. The company focuses on tungsten‑related oilfield components and steel pipe products, primarily falling under HS‑code families 7304 (steel tubes and pipes) and 7307 (tube fittings). All items are described using API designations such as “Well Tubing A Class” or “Screw Drill 1.5‑5.5 m”, indicating compliance with API 5CT and related drilling standards. The supplier’s tier is recorded as imported with a harbor trust tier, reflecting its role in cross‑border trade.

The catalogue includes API Well Tubing C Class, API Screw Drill 1.5‑5.5 m, API Mandrel 1.5‑5.5 m, API Well Tubing A Class (HS 7304.23, tungsten‑alloy coated carbon‑steel base), API Well Tubing B Class (HS 7304.29, steel substrate with tungsten‑nickel‑iron or tungsten‑cobalt coating), and Well Tubing Coupling 107 (HS 7307.23, carbon/alloy‑steel base with WC/Co overlay). Materials are specified as tungsten‑alloy coated carbon steel or alloy steel bases, typical for high‑wear oilfield tubing that must resist abrasion and corrosion. The product names follow API naming conventions, which signal dimensional standards, pressure ratings and threading profiles used worldwide.

Product Range and Specialties of T.F.T. International New Material Engineering Co., Ltd.

The listed products cover three main API‑defined families: well tubing (Classes A, B, C), drilling tools (screw drill and mandrel), and a coupling accessory. In the oil‑field market, API 5CT tubing is graded by class (A, B, C) with Class A representing the highest tensile strength (≈ 620 MPa) and Class C the lowest (≈ 415 MPa). Tungsten alloy coatings are commonly applied in thicknesses of 0.5 - 2 mm to provide hardness values above 1 800 HV and improve wear resistance. Typical specifications for the screw drill and mandrel include a 1.5 - 5.5 m length range, Ø 30 - 120 mm, and a hardened steel core meeting ASTM A193 standards.

Industry practice for these categories includes optional certifications such as API 5CT product data sheets, ISO 9001 quality management and, for certain regions, CE marking for pressure equipment. Buyers often request detailed coating reports (e.g., X‑ray fluorescence composition, micro‑hardness, adhesion tests) and dimensional inspection certificates (ISO 2768 tolerance). The coupling accessory (HS 7307.23) is usually supplied in standard 40 ft containers with protective palletizing to prevent coating damage during transit.

Trade and Export Information - T.F.T. International New Material Engineering Co., Ltd.

Hong Kong serves as a major trans‑shipment hub for oil‑field equipment destined for the Middle East, Southeast Asia and African markets. HS 7304.23 and 7304.29 products are classified under chapter 73, which commonly requires a commercial invoice, packing list, and a certificate of origin for customs clearance in importing countries. Many importers in the Gulf Cooperation Council (GCC) and West Africa request API certification and material test reports in addition to a Declaration of Conformity to meet local regulator standards.

Logistically, steel tubing and couplings are typically packed in wooden crates or bulk steel drums, with a maximum gross weight of about 20 t per 40 ft container. Common Incoterms used by Hong Kong exporters include FOB Hong Kong and CIF destination port, allowing buyers to arrange inland freight and insurance. Export compliance in Hong Kong often involves the Trade and Industry Department’s export licensing for controlled metal products, though no specific licensing is indicated for the listed items.

Sourcing from T.F.T. International New Material Engineering Co., Ltd. - Buyer Guidance

Buyers should request the full API 5CT product data sheet for each tubing class, confirming dimensions, pressure rating (e.g., 10 kpsi for Class A) and tensile strength. A material certificate verifying the tungsten alloy composition (e.g., W‑Ni‑Fe 70‑30 % or WC/Co 80‑20 %) and coating thickness report should be obtained before finalising the order. Verify that the HS codes supplied (7304.23, 7304.29, 7307.23) match the product description on the commercial invoice to avoid customs delays.

Typical minimum order quantities for coated tubing run in multiples of 5 m lengths, with lead times of 4 - 6 weeks after receipt of approved test reports. Requesting a pre‑shipment sample of the coating (approximately 100 mm × 100 mm) can help verify hardness and adhesion. Ensure that the supplier can provide ISO 9001 or equivalent quality management documentation, as this is a common prerequisite for downstream manufacturers in the oil‑field sector.

What are the HS codes for the well tubing products?

API Well Tubing A Class is listed under HS 7304.23 and API Well Tubing B Class under HS 7304.29. Both codes fall within chapter 73 for steel tubes and pipes.

Which certifications should I ask for before purchasing?

Request the API 5CT product data sheet, a material test report for the tungsten alloy coating, and any ISO 9001 quality management certificate the supplier holds. Additional CE or local pressure‑equipment certification may be required by the import market.

What typical dimensions are offered for the screw drill and mandrel?

Both the API Screw Drill and API Mandrel are offered in lengths from 1.5 m to 5.5 m, with standard diameters ranging from 30 mm to 120 mm. Exact dimensions are specified in the product data sheet.

How is the tungsten coating applied and verified?

Coating is usually applied by high‑temperature sintering of WC/Co or W‑Ni‑Fe powders onto the steel substrate, achieving a thickness of 0.5 - 2 mm. Verification is done through X‑ray fluorescence for composition and micro‑hardness testing (≥ 1 800 HV).

What packaging is used for the well tubing and coupling?

Products are typically packed in wooden crates or bulk steel drums, with pallets for the coupling accessory. Packaging is designed to protect the coating from mechanical damage and moisture during sea freight.

What are the common Incoterms used for these exports?

Exporters from Hong Kong frequently use FOB Hong Kong for buyer‑controlled shipping or CIF destination port when the seller arranges freight and insurance.

Are there any import restrictions for these items?

Importing countries usually require a commercial invoice, packing list, certificate of origin and the API product data sheet. Some jurisdictions may also demand a local conformity assessment for pressure equipment.

What is the typical lead time after order confirmation?

Lead times are generally 4 - 6 weeks, depending on coating verification, material availability and the size of the order.
