Ice Machine Export: How SP277 Exemption Saved 70% on Freight Costs

2026-07-31 · DocumentationHS 8418.69SP277

The Situation

A home appliance exporter had a batch of commercial ice machines to ship from Shanghai to Southeast Asia. Each unit contained R290 (propane) refrigerant — approximately 0.15 kg per machine. The client had been told by another forwarder that any equipment containing refrigerant gas must be declared as DG Class 2.1 (flammable gas), requiring UN packaging certification and full dangerous goods procedures.

The Problem

Quoted freight costs 3–4× higher than general cargo due to DG surcharges
Shipping lines refused bookings for DG-classified equipment
UN packaging certification not practically achievable for the complete machine
Estimated 7–10 working days for DG declaration and inspection alone
Shipment delayed by over one month

The Regulatory Basis

Under IMDG Code Special Provision 277 (SP277):

Equipment containing refrigerant gas where the charge per unit does not exceed 12 kg is not subject to the IMDG Code
This exemption applies to: refrigerators, freezers, air conditioners, ice machines, heat pumps, dehumidifiers, and other refrigerant-containing appliances
Equipment must be secured to prevent accidental activation and leakage during transport

How We Solved It

Step 1 — Verify the Threshold

We requested the technical specification sheet and confirmed: R290 refrigerant charge = 0.15 kg per unit, well under the 12 kg SP277 limit.

Step 2 — Reissue All Transport Documents

Every document was reissued with the correct classification: "Not restricted per IMDG Code SP277."

SDS — with SP277 exemption noted on the shipping section
DG Classification Report — conclusion: "Non-restricted cargo per SP277"
Exemption Letter — bilingual (CN/EN) explaining SP277 applicability, with refrigerant charge data
Letter of Compliance — for the shipping line, confirming all regulatory requirements

Step 3 — Booking & Declaration

With the revised documents, the same shipping line accepted the booking as general cargo immediately. The booking note was annotated "IMDG SP277 — NOT RESTRICTED" for clear communication to destination agents and customs.

Key Takeaway

SP277 is an automatic exemption under the IMDG Code — it does not require any application or approval. If your documents clearly demonstrate a refrigerant charge < 12 kg per unit, you can ship as non-DG. Many forwarders either don't know this rule or don't proactively apply it.

Result

✅ Shipped as general cargo — no DG surcharges, no UN packaging certification
✅ Freight cost reduced by approximately 70%
✅ All documents prepared in 2 working days
✅ Same document template reused for all subsequent shipments
