Frequently Asked Questions (FAQs)

General

We supply shipping containers and modular container cabins for storage, logistics, and project use. This includes standard sizes (10ft, 20,ft 40ft), high cube units, side-access configurations, insulated containers, and occasionally refrigerated containers, depending on inventory availability.

Mariner Containers operates in the United States with order fulfillment through our Houston, Texas facility. International deliveries are arranged on a case-by-case basis.

Yes—delivery is available nationwide, subject to carrier access, road restrictions, and site accessibility. Remote locations may require additional scheduling or special routing.

In many cases, we can provide detailed photos and specifications prior to dispatch. Physical inspection depends on the inventory location, safety rules at the yard, and scheduling. Contact us early to confirm viewing options.

Container Conditions & Specifications

  • New (One-Trip): Used once in international cargo; minor handling marks may be present.

  • Used (Wind & Watertight): Pre-owned but sealed against wind and water; cosmetic wear is normal.

  • Used (Cargo-Worthy): Suitable for continued transport use; visual wear consistent with prior service is expected.

No. Used containers vary in appearance. Dents, surface rust, paint variations, and markings are normal and generally do not affect structural or functional performance. The condition category guides expectations.

Containers labeled as “New (One-Trip)” are not factory-fresh; they have completed a single cargo journey and may show light handling marks.

Refrigerated units may be available depending on inventory. Listings will specify if the container is refrigerated, insulated-only, or intended for storage use. Confirm intended use before purchase.

Pricing & Quotes

Pricing depends on container size, type, condition category, market availability, and any requested upgrades or modifications.

Unless stated otherwise, product prices exclude delivery. Shipping fees depend on distance, container size, and site access, and are confirmed prior to dispatch.

Yes, pricing may vary for multi-unit orders due to logistics and volume handling. Request a quote with quantity and delivery ZIP code(s) for accurate pricing.

Shipping & Delivery

Estimated transit time for most U.S. deliveries is 3–10 business days after order confirmation, depending on routing, carrier availability, and site accessibility. Timelines are estimates and not guaranteed.

    • Clear vehicle access and turning space

    • Stable, level placement surface

    • No overhead obstructions (trees, power lines, structures)

Customers are responsible for local zoning, permitting, and compliance. We can provide general guidance but final responsibility remains with the buyer.

Risk transfers to the customer upon successful delivery at the agreed location. Customers are responsible for damage, theft, or relocation after delivery.

Payments, Tax & Documentation

Bank wire transfers are preferred for high-value orders. Credit/debit card payments may be available depending on order value and verification requirements. Full payment is required before dispatch unless a written deposit arrangement is approved.

Sales tax is based on the delivery location. Tax-exempt customers must provide valid exemption documentation prior to payment for review and approval.

Yes. Invoices and purchase documentation can be provided for accounting and procurement purposes. Request them at the time of order.

Returns, Refunds & Cancellations

We have a two-stage return framework:

  • 7-day inspection period: For reporting incorrect unit, condition, major functional defects, or transport damage.

  • Up to 30 days: Conditional returns may be requested if the container remains unmodified, unused, and in substantially the same condition.

Conditional returns are assessed case-by-case. Eligibility depends on the container remaining in the delivered condition, without modifications or extended use. Return freight costs may apply depending on the reason.

Cancellations are possible before dispatch scheduling. If logistics or carrier planning has begun, administrative or carrier costs may apply.

Customization & Modifications

Some modifications are available depending on project scope. Each request is assessed individually.

Timeframes vary based on complexity, materials, and workshop schedule. Discuss deadlines before placing an order.

Yes, project-based or multi-unit modifications can be arranged. Time and pricing depend on scope and coordination requirements.

High-Value Transactions & Fraud Prevention

Shipping containers are high-value industrial goods. Identity verification and fraud monitoring help ensure secure transactions and prevent chargebacks or unauthorized payments.

All payments are processed through secure channels. Mariner Containers never changes bank instructions via email without formal verification. Customers are responsible for confirming payment details before sending funds.
