CPTPP and Insole Sourcing from Vietnam: Tariff Benefits, Rules of Origin and OEM/ODM Opportunities

CPTPP can reduce or eliminate import duties on qualifying insoles sourced from Vietnam, creating cost-saving opportunities for brands, distributors and OEM/ODM buyers. These benefits depend on the product’s tariff classification, rules of origin and supporting documentation. This guide explains how to assess potential savings and align materials, manufacturing and sourcing decisions with your target market’s requirements.

CPTPP is a trade agreement that provides preferential market access between its members, including reduced or eliminated import duties for eligible goods.

As of October 2026, its 12 members are Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United Kingdom and Vietnam. The United States, China and EU countries are outside the agreement.  

For insole buyers, CPTPP creates a reason to evaluate Vietnam within a wider sourcing strategy. A qualifying shipment may carry a lower import duty than an otherwise comparable shipment entering under the standard tariff.

Three questions should guide the assessment:

• Commercial value: Does the available preference create a meaningful saving for the intended product and order volume?
• Origin eligibility: Can the proposed materials and production process satisfy the applicable rule?
• Practical delivery: Can the supplier provide consistent products and the information needed to support the preference claim?

A Vietnamese supplier address or a “Made in Vietnam” label does not, by itself, establish eligibility for CPTPP treatment. Preferential origin requires its own assessment.

The purchasing objective is therefore to combine a suitable product, reliable manufacturing and a supportable tariff position.

Canada, Mexico, Japan, Australia, New Zealand and the United Kingdom provide a useful initial shortlist for buyers evaluating Vietnam-made insoles. Their inclusion here is a starting point for commercial investigation, rather than a ranking of market size or expected growth.

The following product directions are illustrative. Buyers should validate them through their own customers, retail partners and sales data.

Start with the market where the business has the clearest customer relationship and product proposition. A distributor with established work-footwear accounts may have a stronger initial opportunity in work insoles than in an unfamiliar specialist sports category.

Before expanding, establish a realistic retail price, channel margin, size range and replenishment plan. A tariff preference can support those economics, but it cannot establish consumer demand.

Begin with the importing country’s tariff schedule. Identify the finished product’s national tariff code, the import date, the standard most-favoured-nation (MFN) rate and any preferential rates that may apply.

For example, Canada’s 2026 tariff schedule lists an MFN duty of 5% and a CPTPP rate of Free for tariff item 6406.90.90. This comparison applies only when the goods are correctly classified under that item and qualify for the preference. It is not a universal rate for every product marketed as an insole. cbsa-asfc.gc.ca

Buyers should also compare other available tariff treatments. The relevant saving is the difference between CPTPP and the alternative the shipment could actually use.

Consider an illustrative Canadian shipment correctly classified under the item above, with a confirmed customs value of C$100,000.

This calculation isolates import duty. It does not represent the shipment’s full landed cost or imply that every order becomes 5% cheaper overall.

A purchasing comparison should also account for:

• Product price, tooling and development costs.
• Packaging and pre-shipment inspection.
• Inland transport, international freight and insurance.
• Customs clearance, applicable taxes and delivery charges.
• Origin assessment and document preparation.
• Inventory financing, storage and expected replenishment costs.

Compare quotations on the same delivery basis, with equivalent specifications, order quantities and quality requirements. A lower duty bill may be offset by higher freight, an unsuitable minimum order quantity or additional development work.

For repeat programmes, assess the annual effect. Smaller duty savings can become commercially useful across multiple shipments, provided the supply arrangement remains stable.

CPTPP may operate alongside another trade agreement. For example, the UK–Vietnam Free Trade Agreement remains available alongside CPTPP for trade between the two countries. Qualification under one agreement does not automatically establish qualification under the other.

For each product, compare:

1. The tariff rate available at the intended import date.
2. The original rule is that the actual supply chain can satisfy.
3. The accepted proof of origin and document-preparation process.
4. The ongoing cost of maintaining the evidence.

Where two agreements offer the same duty rate, the more practical option may be the one that fits the established materials, production and documentation process.

Record the selected agreement in the sourcing plan so the supplier, exporter, importer and customs broker work from the same assumptions.

Classification comes first because it determines which tariff and product-specific origin rule must be examined.

Heading 64.06 includes removable insoles and heel cushions. However, Chapter 64 excludes certain orthopaedic articles classified under heading 90.21. Buyers should avoid assuming that all products described commercially as “insoles” share one classification.

Prepare a classification file containing the product description, materials, construction, intended function, photographs and, where useful, a physical sample. A marketing term such as “orthotic” should not replace a review of the actual product.

Ask the customs broker to confirm the destination-specific code before using a duty rate in a quotation or margin calculation. Where classification remains uncertain, discuss whether an advance ruling would be appropriate.

For goods classified under heading 64.06, the published CPTPP product-specific rule provides two alternative routes:

These are alternatives within the product-specific rule, subject to the agreement’s other applicable conditions. Confirm the rule and tariff version used by the importing country. Specific Rules of Origin

The build-up and build-down methods use different calculations involving the value of the good and originating or non-originating materials. The thresholds should not be presented as a simple requirement to purchase a fixed percentage of materials from Vietnamese suppliers.

For the development team, the practical task is to document component classifications and values early. That makes the origin assessment part of the product brief, before tooling and volume commitments.

Yes, potentially. CPTPP allows qualifying production using non-originating materials when the finished goods satisfy the applicable requirements. China is outside CPTPP, so Chinese-origin inputs cannot be treated as originating merely because the buyer operates factories in both countries. Cumulation applies to eligible materials and production within CPTPP parties under the agreement’s conditions.

A practical implication of the heading 64.06 rule is that properly classified raw materials outside Chapter 64 may support the chapter-change route when processed into the finished product. Imported components already classified within Chapter 64 require a closer assessment, the RVC alternative may be relevant.

The review should cover the complete bill of materials: cushioning, support components, top covers, adhesives and other inputs, together with the operations performed in Vietnam.

For purchasing teams, the useful question is: Can this particular construction and production plan be documented against the applicable rule?

Agree how material substitutions will be reviewed. A component change that appears minor commercially may still require the origin assessment and product validation to be updated.

Before finalising an OEM/ODM order, buyers should turn discussions about preferential duties into a documented review of the product, manufacturing plan and shipment requirements.

• Start with the destination and tariff treatment. Confirm the importing country, expected shipment date, product description and tariff classification. Compare the applicable standard and preferential rates, then identify the trade agreement intended for the shipment.
• Review the materials and production arrangements. Check the approved bill of materials, relevant component classifications, origin evidence and actual manufacturing site. The eligibility assessment should identify the applicable origin rule, any required calculations and the assumptions supporting the conclusion.
• Agree on documentation responsibilities. Establish which proof of origin is accepted for the trade route, who prepares it and who checks it before shipment. The manufacturer can provide material and production information, while the exporter and importer should coordinate how that evidence reaches the party claiming preferential treatment. Responsibilities for retaining supplier, production and shipment records should also be clear.
• Check the shipping route and any third-country transit. CPTPP allows transit through non-member countries under specified conditions, including customs control and restrictions on processing. Buyers should therefore review the actual route, handling arrangements and supporting transport records when assessing eligibility.
• Establish change control for repeat orders. Changes to materials, suppliers, production sites or product construction should trigger a review of the relevant specifications and origin assessment. The bill of materials used for customs purposes should correspond to the product that is approved and manufactured.

Request a proposed document pack during sampling. Reviewing it before production gives the team time to resolve missing information, clarify responsibilities and align product approval with the requirements for claiming preferential duties.

A manufacturing network in China and Vietnam gives buyers more production-planning options, but each project still needs a defined allocation of work.

A useful starting point is to separate development, material procurement, component production, final manufacturing, quality inspection and export preparation. Determine which site can perform each activity to the approved specification, then assess the resulting cost, lead time and origin position.

For example, a proposed programme might use development resources or material suppliers in China while carrying out specified production operations in Vietnam. That arrangement should be evaluated against the product’s origin rule before preferential duty treatment is included in the business case.

Buyers should compare three practical scenarios:

• Production at the current site: Establish the existing cost, quality and delivery baseline.
• Production at the alternative site: Identify tooling, process, sampling and documentation work needed to qualify the transfer.
• A planned allocation across both sites: Evaluate the additional material movements, coordination and inspection requirements.

Transferring a design does not remove the need to approve production samples from the receiving factory. Confirm dimensions, fit, material behaviour, bonding and appearance against the agreed reference.

Similarly, a shared corporate group should not be treated as evidence that both factories have identical equipment, processes or approved capacity for the project. Ask which operations will occur at each location and how repeat orders will be controlled.

The strongest sourcing plan connects a commercial advantage with a repeatable manufacturing process. It also identifies the changes that would trigger renewed technical and origin checks.

For a Vietnam sourcing project, the discussion should begin with the intended market and product requirements. An effective development brief connects five areas:

1. Market and application: Define the destination, sales channel, intended user and footwear type.
2. Product specification: Establish support geometry, cushioning, thickness, materials, sizing, branding and packaging.
3. Commercial requirements: Agree expected volumes, target cost, launch timing and replenishment needs.
4. Manufacturing and validation: Review the proposed production arrangement, prototypes, relevant tests and approval criteria.
5. Origin and shipment preparation: Identify the manufacturing and material information needed for the importer and customs adviser to assess preferential treatment.

This approach gives the project team a common basis for evaluating samples, production feasibility and the economics of importing the finished product.

CPTPP can be a useful part of that assessment when the product and supply chain qualify. The development programme should make those conditions clear before the buyer commits to a launch price or production order.
