The products covered by this Order are large diameter seamless carbon and alloy (other than stainless) steel standard, line, and pressure pipes produced, or equivalent, to the American Society for Testing and Materials (ASTM) A-53, ASTM A-106, ASTM A-333, ASTM A-334, ASTM A-589, ASTM A-795, and the American Petroleum Institute (API) 5L specifications and meeting the physical parameters described below, regardless of application. The scope of this Order also includes all other products used in standard, line, or pressure pipe applications and meeting the physical parameters described below, regardless of specification, with the exception of the exclusions discussed below. Specifically included within the scope of this Order are seamless pipes greater than 4.5 inches (114.3 mm) up to and including 16 inches (406.4 mm) in outside diameter, regardless of wall-thickness, manufacturing process (hot finished or cold-drawn), end finish (plain end, beveled end, upset end, threaded, or threaded and coupled), or surface finish. The seamless pipes subject to this Order are currently classifiable under the subheadings 7304.10.10.30, 7304.10.10.45, 7304.10.10.60, 7304.10.50.50, 7304.19.10.30, 7304.19.10.45, 7304.19.10.60, 7304.19.50.50, 7304.31.60.10, 7304.31.60.50, 7304.39.00.04, 7304.39.00.06, 7304.39.00.08, 7304.39.00.36, 7304.39.00.40, 7304.39.00.44, 7304.39.00.48, 7304.39.00.52, 7304.39.00.56, 7304.39.00.62, 7304.39.00.68, 7304.39.00.72, 7304.51.50.15, 7304.51.50.45, 7304.51.50.60, 7304.59.20.30, 7304.59.20.55, 7304.59.20.60, 7304.59.20.70, 7304.59.60.00, 7304.59.80.30, 7304.59.80.35, 7304.59.80.40, 7304.59.80.45, 7304.59.80.50, 7304.59.80.55, 7304.59.80.60, 7304.59.80.65, and 7304.59.80.70 of the Harmonized Tariff Schedule of the United States (HTSUS). Specifications, Characteristics, and Uses: large diameter seamless pipe is used primarily for line applications such as oil, gas, or water pipeline, or utility distribution systems. Seamless pressure pipes are intended for the conveyance of water, steam, petrochemicals, chemicals, oil products, natural gas and other liquids and gasses in industrial piping systems. They may carry these substances at elevated pressures and temperatures and may be subject to the application of external heat. Seamless carbon steel pressure pipe meeting the ASTM A-106 standard may be used in temperatures of up to 1000 degrees Fahrenheit, at various American Society of Mechanical Engineers (ASME) code stress levels. Alloy pipes made to ASTM A-335 standard must be used if temperatures and stress levels exceed those allowed for ASTM A-106. Seamless pressure pipes sold in the United States are commonly produced to the ASTM A-106 standard. Seamless standard pipes are most commonly produced to the ASTM A-53 specification and generally are not intended for high temperature service. They are intended for the low temperature and pressure conveyance of water, steam, natural gas, air and other liquids and gasses in plumbing and heating systems, air conditioning units, automatic sprinkler systems, and other related uses. Standard pipes (depending on type and code) may carry liquids at elevated temperatures but must not exceed relevant ASME code requirements. If exceptionally low temperature uses or conditions are anticipated, standard pipe may be manufactured to ASTM A-333 or ASTM A-334 specifications. Seamless line pipes are intended for the conveyance of oil and natural gas or other fluids in pipe lines. Seamless line pipes are produced to the API 5L specification. Seamless water well pipe (ASTM A-589) and seamless galvanized pipe for fire protection uses (ASTM A-795) are used for the conveyance of water. Seamless pipes are commonly produced and certified to meet ASTM A-106, ASTM A-53, API 5L-B, and API 5L-X42 specifications. To avoid maintaining separate production runs and separate inventories, manufacturers typically triple or quadruple certify the pipes by meeting the metallurgical requirements and performing the required tests pursuant to the respective specifications. Since distributors sell the vast majority of this product, they can thereby maintain a single inventory to service all customers. The primary application of ASTM A-106 pressure pipes and triple or quadruple certified pipes in large diameters is for use as oil and gas distribution lines for commercial applications. A more minor application for large diameter seamless pipes is for use in pressure piping systems by refineries, petrochemical plants, and chemical plants, as well as in power generation plants and in some oil field uses (on shore and off shore) such as for separator lines, gathering lines and metering runs. These applications constitute the majority of the market for the subject seamless pipes. However, ASTM A-106 pipes may be used in some boiler applications. The scope of this Order includes all seamless pipe meeting the physical parameters described above and produced to one of the specifications listed above, regardless of application, with the exception of the exclusions discussed below, whether or not also certified to a non-covered specification. Standard, line, and pressure applications and the above-listed specifications are defining characteristics of the scope of this review. Therefore, seamless pipes meeting the physical description above, but not produced to the ASTM A- 53, ASTM A-106, ASTM A-333, ASTM A-334, ASTM A-589, ASTM A-795, and API 5L specifications shall be covered if used in a standard, line, or pressure application, with the exception of the specific exclusions discussed below.

Case number A-588-850 is one of 540 active orders tracked in the database and was established 2022-12-29; the described product range determines which ten-digit lines inherit the cash-deposit obligation. Scope language in the Federal Register document controls.
As of dataset vintage 2026-10-16T16:09:24Z, yes: importers entering covered goods post a cash deposit at the current rate until Commerce's next administrative review publishes revised margins in the Federal Register. Deposit rates can change every review cycle, so confirm the latest Federal Register notice before you quote a figure to your customs broker.
These HTS headings are recorded in the case linkage: 7304.19.10, 7304.19.50, 7304.31.30, 7304.31.60, 7304.39.00, 7304.51.10, 7304.51.50, 7304.59.10, 7304.59.20, 7304.59.60, 7304.59.80. Confirm the exact ten-digit code against the published scope language, because product descriptions rather than codes alone define the legal boundary of the order, and scope rulings occasionally widen or narrow which lines inherit the deposit obligation.
