Shipping Container Suppliers in Massachusetts

Mini Warehousing keeps more than 4,000 units on the ground in Mansfield. That is a lot of steel for one yard, and it means the box you want is usually there this week rather than next month. They sell one-trip, refurbished and used, and they say which is which. Sizes run from 6ft up to 45ft. Nobody else in Massachusetts sells a container that small, and a 6ft box fits in a driveway where a 20ft never will. The shop does its own cutting and welding, turning boxes into concession stands, kiosks and offices. Their steel has held food vendors on the Rose Kennedy Greenway and gear at Fenway, so they know how to work a permit and a tight city drop.

Valtran runs four yards in Massachusetts, at New Bedford, West Bridgewater, Freetown and Mashpee. That Mashpee yard matters more than it looks. Getting a 40ft box over the Sagamore or Bourne bridge adds real money to a Cape delivery, and starting the trip on the Cape side takes that cost off the invoice. The company has sold and rented boxes here since 2002. Stock covers 10ft through 40ft high cube, and they carry the side door and double door units most small yards skip. A side door 20ft is worth asking about if you are loading pallets and cannot swing a full end open. Grades are sold as used, refurbished or new, so ask which tier a quoted price sits in.

Bee Line has sold and rented steel out of the same Springfield yard since 1972. Fifty four years on Page Boulevard is a long run in a trade where yards come and go. The location does work that matters west of Worcester. Most of the Pioneer Valley and all of the Berkshires have no container yard of their own, so a box for Pittsfield or Greenfield gets trucked in from somewhere, and Springfield is the closest somewhere there is. They deliver on their own tilt bed, often the same day. Sizes run 10ft, 20ft, 24ft and 40ft in both standard and high cube heights. No other yard in Massachusetts stocks a 24 foot box. One caution: they publish no grades and no prices, so ask what condition you are buying.

Sterling Container Sales is built around selling, not renting, and the difference shows in how the place is set up. There is an inventory page to browse, a delivery and placement service written out, and a phone number that reaches an owner rather than a call center. They sell 20ft, 40ft and 40ft high cube ground level units and quote delivery against your zip code. Coverage runs from Hingham down through Plymouth and Wareham and out across the canal to the Cape. Buyers listed include towns and municipalities, transportation firms, event organizers and homeowners moving house. The one thing to weigh is age. The company opened in 2024, so there is not much history to check, though it took BBB accreditation early and has no complaints on file.

Trans East posts its container stock in public with prices attached, which very few yards do. The dealer listing carries around 185 units across ten entries, from 20ft boxes built in 2015 at $2,200 up to 2025 40ft units at $8,600. You can see what is on the lot and what it costs before you pick up the phone. Most Massachusetts yards quote by phone and you find out the number after you ask twice. The yard sits on Route 95 in Salisbury, close to the New Hampshire line, and you can collect yourself or have it delivered. Two things to know. They stock 20ft and 40ft only, nothing else, and condition is given by build year rather than by grade, so ask what the steel actually looks like.

Seaspray Container Company sells to homeowners and small businesses along the South Coast, and the whole operation is shaped around that. Boxes go out painted in neutral colors so a 20ft unit sitting beside a house does not look like it fell off a ship. Full inside and outside dimensions are published for every size they carry, which helps when you are measuring a side yard. Patrick and Erin Carr started the company in 2021 and run it as a father and daughter shop. The yard is on Middle Street near the harbor, shared with the family crane business, so they own the trucks that bring your box. They belong to the National Portable Storage Association. Sizes are 20ft, 40ft and 40ft high cube, and grades are not published.
