For many buyers, arranging the first container of commercial air-conditioning equipment feels more complicated than selecting the equipment itself. This guide explains how HVAC equipment is packed, containerized, documented, and insured for sea freight from China — covering container selection, Incoterms, shipping documents, lead times, and damage claims in one place. It reflects how we prepare export orders at our factory in Zhengzhou across our full product range, from light commercial units to industrial chillers.
How HVAC Equipment Is Packed for Sea Freight
Export packing has one job: get the unit through container loading, ocean transit, and at least one transshipment without damage. The standard method is a protective carton around each unit, reinforced by a wooden case, crate, or pallet engineered for container transport. Corner protection, internal bracing, and moisture barriers are added according to the unit type and route.
Accessories — piping kits, controllers, remote units, mounting hardware — are consolidated in the same shipment, packed separately, and itemized on the packing list so nothing is missed at the receiving end.
One detail worth understanding before your first order: smaller equipment such as light commercial AC units typically ships factory-charged with refrigerant and sealed. Larger equipment, including many water-cooled chillers, often ships with a nitrogen holding charge instead, depending on the model and the regulations of the destination country. The nitrogen protects the circuit from moisture and leaks in transit; refrigerant is then charged during commissioning on site.
Choosing a Container: 20GP vs 40GP vs 40HQ
Three container types cover almost all HVAC shipments:
| Container | Internal dimensions (approx.) | Volume (approx.) | Typical use |
|---|---|---|---|
| 20GP | 5.90 × 2.35 × 2.39 m | 33 m³ | Trial orders; dense, heavy cargo such as compact chillers |
| 40GP | 12.03 × 2.35 × 2.39 m | 67 m³ | Standard full-container orders and mixed-model loads |
| 40HQ | 12.03 × 2.35 × 2.69 m | 76 m³ | Volume-driven cargo; the most common choice for HVAC equipment |
Because HVAC equipment is bulky rather than heavy, the 40HQ usually delivers the lowest freight cost per unit. How many units fit depends entirely on the dimensions of the specific models you order, so treat any generic “units per container” figure with caution. We provide a container loading plan with every quotation, showing exactly how your model mix fills the container.
Incoterms for HVAC Buyers: EXW, FOB, CIF, DDP
The Incoterm on your contract determines who books the freight, who insures the cargo, and where responsibility passes from seller to buyer.
| Incoterm | Who books ocean freight | Who insures | Where risk transfers | When it makes sense |
|---|---|---|---|---|
| EXW | Buyer, from the factory door | Buyer | At the factory | Buyers with a strong forwarder network inside China |
| FOB | Buyer’s forwarder; seller handles export clearance to the port | Buyer | On board the vessel at the Chinese port | The most common starting point for first-time importers |
| CIF | Seller | Seller, to the destination port | On board the vessel at origin (despite seller paying freight) | Buyers without their own freight forwarder |
| DDP | Seller, through to delivery | Typically seller | At the named destination | Buyers who want a landed price; availability varies by country |
Most first orders run on FOB: you appoint a forwarder, control your freight cost, and the factory delivers export-cleared goods to the port. If you do not yet have a forwarder, CIF is the simpler route — the factory books the vessel and insures the cargo to your port. Payment terms are agreed separately from the Incoterm, typically by T/T or L/C.
Shipping Documents You Will Receive
A complete HVAC export shipment travels with a predictable document set:
- Commercial invoice — the transaction value used for payment and customs valuation.
- Packing list — every carton, case, and accessory box with weights and dimensions; your checklist at unloading.
- Bill of lading (B/L) — the carrier’s receipt and the document of title; you or your agent need it to release the cargo.
- Certificate of origin — required by most customs authorities. For ASEAN destinations, a Form E certificate may qualify the goods for preferential tariffs, and RCEP certificates apply in other member countries — check with your customs broker before the goods ship, as certificates are easier to issue correctly than to amend.
- Quality certificates — CE, SASO, ESMA, or other conformity documents as applicable to your market.
- Warranty card and manuals — packed with the goods and available in advance as digital copies.
Lead Times: Production + Ocean Transit
Commercial HVAC equipment is generally produced to order. Production typically takes 15–30 days depending on the model and order size; the current lead time is stated on every quotation so you can plan backwards from your project date.
Ocean transit as of 2026 typically falls within these ranges, subject to carrier schedules, routing, and port conditions:
- China to Jebel Ali or Dammam: typically 2–4 weeks
- China to European ports: typically 4–6 weeks
- China to West Africa: typically 4–7 weeks
- China to Latin America: typically 4–8 weeks

Insurance and Damage Claims
Marine cargo insurance is inexpensive relative to the value of a container of HVAC equipment, and someone must arrange it. Under CIF and DDP, the seller insures. Under FOB and EXW, insurance is the buyer’s responsibility — your forwarder can add it to the booking for a small premium. Do not let a first shipment sail uninsured.
On arrival, inspect the cargo before signing the delivery receipt. If cartons or crates show damage, note it on the receipt, photograph everything before and during unloading, and keep the packaging. Notify the insurer and the supplier promptly: claim windows are short, often a matter of days for visible damage, so check your policy terms in advance.
How to Reduce Shipping Cost per Unit
- Ship full containers (FCL) rather than LCL. LCL adds handling charges and extra touchpoints per unit; a full container is cheaper and safer per unit shipped.
- Mix models in one container. Combining chillers, splits, and accessories in a single container is routine — confirm the loading plan with the factory before ordering.
- Use flat-packed options where available. Some models and components can ship partially knocked down, saving volume.
- Order to container-fill quantities. Ask what quantity of your model mix fills a 40HQ; topping up an order to fill remaining space often costs little against the freight already paid.
Frequently Asked Questions
More answers for importers are available on our FAQ page.
Can different HVAC models be mixed in one container?
Yes. Mixed loads — for example chillers plus light commercial units plus accessories — are common. The factory prepares a container loading plan showing how each model is positioned and secured, so you can confirm the mix before production begins.
Does the factory arrange shipping?
Under CIF or CFR terms, yes — the factory books the vessel and, under CIF, insures the cargo to your port. Under FOB or EXW, your own freight forwarder books the shipment while the factory handles export packing and, under FOB, export clearance and delivery to the port.
How is the equipment protected against transit damage?
Each unit ships in a carton reinforced by a wooden case, crate, or pallet engineered for container transport and transshipment, with internal bracing and corner protection. Larger chillers often carry a nitrogen holding charge to protect the refrigerant circuit, depending on model and destination regulations.
What happens if goods arrive damaged?
Note the damage on the delivery receipt before signing, photograph the cargo and packaging, and notify the insurer and supplier immediately. With marine cargo insurance in place and prompt documentation, claims are normally resolved between the insurer, carrier, and supplier without the buyer absorbing the loss.
