Last updated: July 2026 data

Seamless and welded copper tubes and pipes are the dominant material for residential and commercial plumbing, HVAC refrigerant lines, and medical gas distribution — sectors governed by ASTM standards (B88 for plumbing, B280 for ACR) that specify dimensional tolerances, temper, and cleanliness requirements. The distinction between plumbing tube (Type K, L, M) and air-conditioning/refrigeration (ACR) tube is commercially critical and should be reflected in the product description and mill certification accompanying the import entry. Section 232 tariff measures apply to copper tube and pipe, and importers should verify whether any country-specific exclusions are in effect for their supply source. Antidumping and countervailing duty orders have historically covered certain copper pipe and tube products from specific origins, making origin verification a recurring compliance priority.

Frequently Asked Questions

What is the difference between ASTM B88 plumbing tube and ASTM B280 ACR tube, and why does it matter for import compliance?

ASTM B88 tube (Types K, L, M) is sized by nominal outside diameter for water plumbing and is sold in straight lengths or coils; ASTM B280 ACR tube is sized by actual outside diameter, is cleaned and capped for refrigerant service, and must meet stricter internal cleanliness requirements. Importing ACR tube labeled or invoiced as plumbing tube (or vice versa) can create both classification issues and product liability exposure if the tube is used in the wrong application.

Have antidumping orders applied to copper tube and pipe, and how should importers manage that risk?

Yes, antidumping and countervailing duty orders have been imposed on certain copper pipe and tube products from specific countries. Importers should search the ITA's active order database using the product description and country of origin before sourcing, obtain a scope ruling if the product's coverage is uncertain, and work with a licensed customs broker to determine bonding and cash deposit requirements.
