China CCC for cables: scope and what it does not cover

What CCC is

China Compulsory Certification (CCC) is the mandatory product certification scheme for products sold on the Chinese domestic market in listed categories. It is administered under the Certification and Accreditation Administration of China (CNCA), with implementation rules for each product category, testing by designated laboratories and factory inspection. Products in scope need the certificate and the CCC mark before they are sold in China.

For wire and cable, the scheme covers only part of what a cable plant makes. Several consistent secondary sources, including certification consultancies, describe the scope as follows; the desk recommends checking the current CNCA implementation rules for a specific product, because the rules are revised from time to time.

Scope: low-voltage PVC and rubber insulated cable

The key line is the voltage. CCC covers PVC and rubber insulated cable rated 450/750 V and below; the 0.6/1 kV XLPE power cable that makes up much of a project bill of quantities sits under GB/T 12706 and is outside CCC. Some sources have claimed otherwise; the desk does not use those claims because they conflict with the consistent summaries of the scope.

The reference models on this site show the split. The 450/750 V single-core 2.5 mm2 PVC wire on the building wire page is the 60227 IEC 01 type, the family CCC covers for the Chinese market. The 0.6/1 kV Cu/XLPE/PVC 4x25 mm2 YJV cable on the LV power cables page is a GB/T 12706.1 product and is not in CCC scope.

Some products sit closer to the line. Control cable such as the 450/750 V KVV type is made to GB/T 9330, a different standard from GB/T 5023, so whether a given control cable type needs CCC is a question for the current implementation rules rather than an assumption either way. The desk records the answer per product when it matters, for example for a project inside China.

Testing for CCC is carried out by laboratories designated by CNCA, and these include international organisations operating in China: UL's wire and cable laboratory in Suzhou, for example, was accredited by CNCA as a CCC testing laboratory for parts of GB/T 5023. That does not link a CCC certificate to any UL listing; the two schemes remain separate.

What a CCC mark tells an export buyer

When a plant shows CCC certificates, three things can reasonably be inferred, and several things cannot.

• It can indicate that the plant sells the certified types on the Chinese market, that those types have been tested by a designated laboratory against GB/T 5023 or GB/T 5013, and that the plant has been through CCC factory inspection for them. That is useful background for an audit.
• It does not show that a power cable, control cable, fibre cable or any type outside the certificate meets any standard. It does not replace the certificate your destination market needs: a DoP under the EU CPR, a listing for US projects, a TISI licence in Thailand, a SABER PCoC, an NRCS LoA or a BASEC approval.
• It does not transfer to export production automatically. An export order is made to the buyer's specification, which may differ from the certified domestic type in colour, marking, thickness or standard.

Because GB/T 5023 follows IEC 60227 and GB/T 5013 follows IEC 60245, a plant with CCC for those types usually already understands the IEC construction. That makes it a reasonable candidate for IEC 60227 based export products, including the identical-adoption parts of Thailand's TIS 11, but the destination certificate still has to be obtained for the export construction. See Thailand TIS 11 and the cable standards map.

Using CCC information in a factory audit

The desk treats CCC as one data point in a wider plant assessment. It helps to know which product lines a plant runs for the domestic market under third-party inspection, but the audit still looks at the lines, laboratory and records directly. The points checked include:

1. Certificate status and scope: current, and covering the types the plant claims.
2. Laboratory equipment: conductor resistance bridge, high-voltage test set, thickness measurement, and for power cable the routine voltage test equipment.
3. Routine records: conductor resistance against IEC 60228 per drum, spark test logs, dimension checks.
4. Raw material control: copper rod sourcing and compound incoming inspection.
5. Export experience: which destination certificates the plant already holds for which constructions.

The full checklist is in the cable factory audit checklist and on the factory audit page.

Where CCC matters for sourcing

For most buyers using the desk, CCC is background rather than a requirement, because the goods are exported. It becomes directly relevant in three cases: when cable is supplied into a project inside China, when a buyer wants domestic-market types as a reference for the construction, and when a plant's certified range is used to shortlist suppliers for IEC 60227 type products.

China's cable industry is large and concentrated. Yixing in Jiangsu passed 100 billion yuan of wire and cable output by the end of 2020 (Jiangsu provincial news, 2021), and the Ningjin cluster in Hebei reported revenue of 68.89 billion yuan across 2,393 enterprises in 2024 (Hebei industry department, 2025). Within clusters of that size, CCC status is one of several filters the desk applies to narrow the shortlist, alongside destination certificates and audit results.

If your order mixes in-scope and out-of-scope products, such as building wire and 0.6/1 kV power cable for the same site, list each item with its standard and destination in the quote request. The desk will confirm in writing which certificates apply to each line and which partner plant holds them.
